v0.29.2 feat: thin-client mode (gbrain init --mcp-only + gbrain remote ping/doctor + topologies) (#732)
* feat(config): add remote_mcp field + isThinClient() helper Adds a top-level optional remote_mcp config block to GBrainConfig (issuer_url, mcp_url, oauth_client_id, oauth_client_secret) for thin-client installs that consume a remote `gbrain serve --http` over MCP instead of running a local engine. isThinClient(config) returns true when remote_mcp is set; used by the CLI dispatch guard, doctor branch, and init re-run guard. The engine field stays as today (postgres|pglite); thin-client mode is a separate config field, NOT an engine kind extension (codex outside-voice review flagged the engine='remote' extension as overreach). GBRAIN_REMOTE_CLIENT_SECRET env var overrides the config-file value at load time so the secret can stay out of disk for headless agents. Foundation commit for multi-topology v1; no behavior change yet. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(probe): outbound OAuth + MCP smoke probes Adds three pure async functions over the standard fetch API: - discoverOAuth(issuerUrl): GET /.well-known/oauth-authorization-server - mintClientCredentialsToken(tokenEndpoint, id, secret): POST /token - smokeTestMcp(mcpUrl, accessToken): POST /mcp initialize Discriminated 'ok=true' / 'ok=false + reason' return shapes so callers render error messages consistently. No SDK dependency to keep init's setup-flow scope tight; Lane B's mcp-client.ts will pull in the official @modelcontextprotocol/sdk Client for full session semantics. Used by both 'gbrain init --mcp-only' (Lane A's setup smoke) and runRemoteDoctor (Lane A's thin-client doctor checks). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(init): --mcp-only branch + re-run guard Adds 'gbrain init --mcp-only' for thin-client setup. Required flags (or env vars): --issuer-url OAuth root (e.g. https://host:3001) --mcp-url MCP tool dispatch path (e.g. https://host:3001/mcp) --oauth-client-id, --oauth-client-secret Pre-flight runs three smoke probes (discovery, token round-trip, MCP initialize) BEFORE writing the config — fail-fast on bad URL beats fail-late on bad credentials. On success, writes ~/.gbrain/config.json with remote_mcp set and NO local DB created. Re-run guard (A8): when ~/.gbrain/config.json already has remote_mcp, 'gbrain init' (any flag set) refuses without --force. Catches the scripted-setup-loop friction from the user-reported scenario where re-running setup-gbrain on a thin-client machine kept trying to re-create a local DB. Two URLs in config (issuer + mcp) instead of one because OAuth discovery + /token live at the issuer root while tool dispatch is at /mcp — they compose from a common base in practice but reverse-proxy setups need them explicit (codex review #2). Tests: 15 cases covering happy path, env-var-supplied secret stays out of disk, all four required-flag missing-error paths, three smoke-failure paths, network-unreachable path, and the four re-run guard variants (default/--pglite/--mcp-only without --force / with --force). Uses async Bun.spawn (NOT execFileSync) — sync exec deadlocks against in-process HTTP fixtures because the parent's event loop can't accept connections while sync-blocked on a child. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(doctor): runRemoteDoctor for thin-client mode Replaces every DB-bound check from runDoctor() with a tighter set scoped to 'is the remote MCP we configured actually reachable?'. Five checks: - config_integrity (URL fields well-formed) - oauth_credentials (secret resolvable from env or config file) - oauth_discovery (GET /.well-known/oauth-authorization-server) - oauth_token (POST /token client_credentials) - mcp_smoke (POST /mcp initialize) Output shape matches the local doctor's Check surface so JSON consumers can union the two without conditional logic. schema_version is 2 (matches local doctor). collectRemoteDoctorReport() is the pure data collector; runRemoteDoctor() is the print/exit wrapper. Tests pin the data collector so we don't have to intercept stdout / process.exit. Tests: 12 cases over a tiny in-process HTTP fixture covering happy path, every probe failure mode (404/parse/auth/network/server-error), malformed-URL config integrity, missing-secret short-circuit, and the env-var-overrides-config-file secret resolution. withEnv() helper used for env mutations to satisfy the test-isolation lint. Module is added but not yet wired into the CLI doctor branch; the wiring lands in the next commit (cli dispatch guard + doctor routing). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(cli): thin-client dispatch guard + doctor routing Adds a single canonical refusal at the top of handleCliOnly() for the 9 DB-bound commands when ~/.gbrain/config.json has remote_mcp set: sync, embed, extract, migrate, apply-migrations, repair-jsonb, orphans, integrity, serve Single dispatch check (not 9 sprinkled assertLocalEngine calls per codex review #1) — avoids the blast radius of letting commands enter connectEngine before the check fires. Refused commands exit 1 with a canonical error naming the remote mcp_url. doctor branch routes to runRemoteDoctor when isThinClient(config) returns true; falls through to the existing local-doctor flow otherwise. Wires the module added in the previous commit into the user-facing CLI surface. Safe commands (init, auth, --version, --help, etc.) still work in thin-client mode and are NOT in the refused set. Tests: 14 cases — 9 refused commands × 1 each, 2 safe commands, 1 doctor-routing assertion (fingerprints the thin-client output by 'mode:"thin-client"' in JSON), 2 regression tests asserting local config still passes through normally. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs(topologies): multi-topology architecture guide + setup skill Phase A.5 New docs/architecture/topologies.md covering three deployment shapes: 1. Single brain (today's default) 2. Cross-machine thin client (consume a remote brain over MCP) 3. Split-engine per-worktree (Conductor users with per-worktree code engines + shared remote artifacts brain) Each topology gets an ASCII diagram, when-it-fits guidance, and concrete setup recipes. Topology 3's alias-level routing footgun (wrong alias = silent wrong-brain writes) is called out explicitly per codex review #6. Topology 3 needs zero gbrain code changes — GBRAIN_HOME already overrides ~/.gbrain and 'gbrain serve --http --port N' already runs on any port. gstack composes these primitives on its side. skills/setup/SKILL.md gets Phase A.5 BEFORE the local-engine phases. Asks the user which topology fits, walks thin-client setup through 'gbrain init --mcp-only', skips Phases B/C/C.5/H entirely for thin clients (host's autopilot handles sync/extract/embed). README.md gets a one-line link to the topology doc from the Architecture section. llms-full.txt regenerated to include the new doc. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(e2e): thin-client end-to-end skeleton Spins up 'gbrain serve --http' against real Postgres, registers a client with read,write,admin scope, runs 'gbrain init --mcp-only' from a separate tempdir GBRAIN_HOME, exercises the canonical thin-client flows: - init --mcp-only succeeds against the live host - doctor reports mode: thin-client + all checks green - sync is refused with the canonical thin-client error - re-running init refuses without --force Tier B flows (gbrain remote ping / doctor) will be added alongside their Lane B implementation. Skips when DATABASE_URL unset (matches the e2e gate convention used across the suite). Async Bun.spawn (NOT execFileSync) so the test event loop stays responsive — execFileSync deadlocks against in-process HTTP fixtures because the parent's event loop can't accept connections while sync-blocked on a child process. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(doctor): doctorReportRemote core for thin-client + run_doctor op Adds three new exports to src/commands/doctor.ts that the run_doctor MCP op + gbrain remote doctor CLI both consume: - DoctorReport interface schema_version=2 stable shape - computeDoctorReport(checks) status + health_score math - doctorReportRemote(engine) focused 5-check thin-client surface doctorReportRemote runs: 1. connection (engine reachable + page count via getStats) 2. schema_version (engine.getConfig('version') vs LATEST_VERSION) 3. brain_score (the 5-component composite) 4. sync_failures (file-plane JSONL count from gbrainPath('sync-failures.jsonl')) 5. queue_health (Postgres-only: stalled active jobs > 1h) Engine-agnostic: works on both Postgres and PGLite via engine.executeRaw + engine.getConfig + engine.getHealth — no reliance on db.getConnection() which is Postgres-only. Deliberately a focused subset of the local doctor surface, NOT a full mirror. Generalizing to lint/integrity/orphans is filed as follow-up pending demand. Local doctor (runDoctor) is unchanged; operators on the host machine still get the full check set. schema_version=2 matches the local doctor's --json output schema, so JSON consumers can union the two without conditional logic. Tests: 11 unit cases against PGLite covering the 5-check happy path, schema version reporting (latest), PGLite-specific queue_health informational message, and the score+status math via computeDoctorReport. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(mcp-client): outbound HTTP MCP client over @modelcontextprotocol/sdk New src/core/mcp-client.ts wraps the official SDK's Client + StreamableHTTPClientTransport with OAuth client_credentials minting, in-process token caching with expires_at, and refresh-on-401 retry. Public surface: - callRemoteTool(config, toolName, args) tool call w/ auto-refresh - unpackToolResult(res) parse content[0].text JSON - RemoteMcpError discriminated by `reason` Token cache: module-level Map keyed by mcp_url. CLI processes are short-lived; the cache amortizes when one invocation makes multiple calls (gbrain remote ping submits then polls). Persisting to disk would be a credential-on-disk surface for marginal benefit since /token round-trip is sub-100ms. 401 retry: ONLY for mid-session token rotation (initial good token → stale → 401). If the FIRST mint fails auth, surface immediately as RemoteMcpError(auth) — retry won't help when credentials are wrong from the start. If a fresh-mint-after-401 still 401s, surface as RemoteMcpError(auth_after_refresh) which the CLI renders with a hint pointing the operator at gbrain auth register-client. Used by gbrain remote ping (submit_job + get_job poll) and gbrain remote doctor (run_doctor). Test-only _clearMcpClientTokenCache export for fixture isolation. Tests: 13 unit cases over an in-process HTTP fixture mimicking gbrain serve --http (OAuth discovery + /token + /mcp JSON-RPC handshake). Covers happy path, token cache reuse + force-refresh, args passthrough, config-error paths (no remote_mcp / no secret), token mint 401, network unreachable, tool isError envelope, and unpackToolResult parse failures. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(operations): add run_doctor MCP op (admin scope, HTTP-reachable) New op in src/core/operations.ts wraps doctorReportRemote() and returns the structured DoctorReport JSON over MCP. scope: 'admin' (system-state read; not for routine consumers) localOnly: false (reachable over HTTP) mutating: false (safe to call repeatedly) params: {} (no caller arguments needed) First read-only diagnostic op exposed over HTTP MCP. Used by gbrain remote doctor — the matching client-side renderer lives in src/commands/remote.ts. Precedent: doctor only. Generalizing run_lint / run_integrity / run_orphans to MCP is filed as follow-up work pending demand. Local doctor stays unchanged; this op is the operator-friendly subset for remote callers. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(remote): gbrain remote ping + gbrain remote doctor Two thin-client convenience commands that round-trip through the host's HTTP MCP endpoint: - gbrain remote ping submit_job(autopilot-cycle) → poll get_job → exit when terminal. The "I just wrote markdown, tell the host to re-index" affordance. - gbrain remote doctor run_doctor MCP op → render the host's DoctorReport → exit 0/1 based on status. Both require a thin-client install (~/.gbrain/config.json with remote_mcp). Local installs get a clear error pointing at the local equivalents. Polling backoff (ping): 1s × 30s, then 5s × 5min, then 10s. Default cap 15min, configurable via `--timeout`. Without backoff, a 5-min cycle would burn 300 round-trips against the host's rate limiter. Payload uses `data: {phases: [...]}`, NOT `params:` — the submit_job op shape takes `data`. Codex review #8 catch. NO `repo` arg passed to autopilot-cycle — uses the server's configured brain repo. This sidesteps TODO #1144 (sync_brain repo-path validation for caller-controlled paths) entirely. src/cli.ts wires the `remote` subcommand into CLI_ONLY + the dispatch. Help (`gbrain remote --help`) and unknown-subcommand handling included. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test(e2e): thin-client Tier B + scope-mismatch regression Extends the existing test/e2e/thin-client.test.ts with three new cases: 1. gbrain remote doctor returns the host's DoctorReport — pins the run_doctor MCP op round-trip. Asserts schema_version=2, all 5 check names present, connection + schema_version ok against a fresh host. 2. gbrain remote ping triggers autopilot-cycle and returns terminal state — pins the submit_job → poll → terminal wire path. Accepts any terminal state (success / failed / dead / cancelled / timeout) because autopilot on an empty no-repo brain may fail-fast in the sync phase. What this test pins is the JSON shape (job_id present, state populated), NOT cycle success on a no-repo fixture. 3. read+write client cannot call run_doctor — codex review #7 regression guard. Registers a separate client with `--scopes "read write"` (no admin), runs `gbrain remote doctor` against it, asserts exit 1 with auth/auth_after_refresh/tool_error reason. Keeps the verification flow honest: the canonical setup MUST require admin scope. `gbrain auth register-client` doesn't have --json, so the test parses the human output for "Client ID:" and "Client Secret:" lines via a helper. Test-level timeout bumped 60s → 120s for the ping wait + auth/init overhead. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * chore: bump version and changelog (v0.29.2) v0.29.2 ships thin-client mode: gbrain init --mcp-only, gbrain remote ping/doctor, run_doctor MCP op, and the docs/architecture/topologies.md deployment guide.

All notable changes to GBrain will be documented in this file.

## [0.29.2] - 2026-05-07
|
||||
|
||||
**Thin-client mode: install gbrain on a laptop without a local DB and have it consume a remote brain over MCP.**
|
||||
**`gbrain init --mcp-only` + `gbrain remote ping` + `gbrain remote doctor` + run_doctor MCP op.**
|
||||
|
||||
You can now run `gbrain init --mcp-only --issuer-url <url> --mcp-url <url>/mcp --oauth-client-id <id> --oauth-client-secret <secret>` on a machine that should NOT have its own brain. No PGLite file gets created. No Postgres connection. Three pre-flight smoke probes run before the config lands so a typo in the URL or a bad credential surfaces up front, not later. The CLI's dispatch guard refuses every DB-bound subcommand (`sync`, `embed`, `extract`, `migrate`, `apply-migrations`, `repair-jsonb`, `orphans`, `integrity`, `serve`) with a single canonical error pointing at the remote host. `gbrain doctor` runs a thin-client check set instead: OAuth discovery, token round-trip, MCP initialize.
|
||||
|
||||
Once configured, `gbrain remote ping` triggers an autopilot cycle on the remote host and polls until terminal so you don't have to wait for the autopilot cron after writing markdown. `gbrain remote doctor` calls a new `run_doctor` MCP op (admin scope, HTTP-reachable) that returns a structured DoctorReport from the remote host's brain. Fast feedback when something's off.
|
||||
|
||||
The new `docs/architecture/topologies.md` documents three deployment shapes (single brain, cross-machine thin client, per-worktree code engines + shared remote artifacts) so users and gstack can compose them deliberately. Topology 3 (per-worktree split-engine for Conductor users) needs zero gbrain code changes — `GBRAIN_HOME` already overrides `~/.gbrain` and `gbrain serve --http --port N` already runs on any port. The new doc spells out the alias-routing footgun (wrong alias = silent wrong-brain writes) explicitly.
|
||||
|
||||
### What this means for you
|
||||
|
||||
A v0.29.1 caller upgrading to v0.29.2 with no setup change gets identical local-only behavior. The thin-client surface is pure opt-in: only fires when `~/.gbrain/config.json` carries a `remote_mcp` block. Existing local-engine installs are unchanged.
|
||||
|
||||
If you want to actually use thin-client mode:
|
||||
|
||||
1. On the host running `gbrain serve --http`: `gbrain auth register-client <name> --grant-types client_credentials --scopes "read write admin"` (admin needed for ping + doctor).
|
||||
2. On the consuming machine: `gbrain init --mcp-only --issuer-url <issuer> --mcp-url <issuer>/mcp --oauth-client-id <id> --oauth-client-secret <secret>`.
|
||||
3. Configure your agent's MCP client to point at the host's `mcp_url` with the bearer token. Per-client snippets in `docs/mcp/`.
|
||||
4. `gbrain doctor` to verify connectivity, `gbrain remote ping` after writes, `gbrain remote doctor` for remote-side health.
|
||||
|
||||
The full setup recipe and three topology diagrams live in `docs/architecture/topologies.md`.
|
||||
|
||||
## To take advantage of v0.29.2
|
||||
|
||||
`gbrain upgrade` does this automatically — no schema migration, no data backfill. The thin-client surface is opt-in via the `--mcp-only` flag.
|
||||
|
||||
If you're setting up a new thin-client install:
|
||||
|
||||
```bash
|
||||
# On the host
|
||||
gbrain serve --http --port 3001
|
||||
gbrain auth register-client neuromancer --grant-types client_credentials --scopes "read write admin"
|
||||
|
||||
# On the thin client
|
||||
gbrain init --mcp-only \
|
||||
--issuer-url https://brain-host:3001 \
|
||||
--mcp-url https://brain-host:3001/mcp \
|
||||
--oauth-client-id <id> --oauth-client-secret <secret>
|
||||
|
||||
# Verify
|
||||
gbrain doctor # thin-client check set: discovery, token, MCP smoke
|
||||
gbrain remote doctor # ask the host to run its own doctor
|
||||
gbrain remote ping # trigger an autopilot cycle on the host
|
||||
```
|
||||
|
||||

|
||||
- output of `gbrain doctor --json` from the thin client

||||

|
||||
|
||||
### Itemized changes
|
||||
|
||||
**New CLI surfaces**:
|
||||
|
||||
- `gbrain init --mcp-only` (`src/commands/init.ts`) — thin-client setup. Pre-flight runs OAuth discovery, `/token` round-trip, and MCP initialize against the remote before writing config. Re-run guard refuses without `--force` when `~/.gbrain/config.json` already has `remote_mcp` set, so scripted setup-loops can't silently re-create a local DB on a thin-client machine.
|
||||
- `gbrain remote ping` (`src/commands/remote.ts`) — submits an `autopilot-cycle` job on the remote via `submit_job` MCP op, polls `get_job` with backoff (1s × 30s, then 5s × 5min, then 10s), exits when terminal. Default cap 15min, override with `--timeout 5m` or `--timeout 30m`. NO `repo` arg passed — autopilot uses the host's configured brain repo, no caller-controlled paths.
|
||||
- `gbrain remote doctor` (`src/commands/remote.ts`) — calls the new `run_doctor` MCP op, renders the DoctorReport. Exit 0/1 based on status.
|
||||
|
||||
**New config field**:
|
||||
|
||||
- `remote_mcp: {issuer_url, mcp_url, oauth_client_id, oauth_client_secret}` on `GBrainConfig`. Two URLs because OAuth discovery + `/token` live at the issuer root while tool dispatch is at `/mcp` — they compose from a common base in practice but reverse-proxy setups need them explicit. `GBRAIN_REMOTE_CLIENT_SECRET` env var overrides the config-file value for headless agents; secrets supplied via env stay out of disk.
|
||||
- `isThinClient(config)` helper in `src/core/config.ts` — single source of truth for the "is this install a thin client?" check used by the CLI dispatch guard, doctor branch, and remote subcommands.
|
||||
|
||||
**New CLI dispatch guard** (`src/cli.ts`):
|
||||
|
||||
- Single top-level check refuses 9 DB-bound commands with a canonical error naming the remote `mcp_url` when `remote_mcp` is set. Runs BEFORE `connectEngine` so commands never enter the engine factory only to fail late. Doctor branches to a new `runRemoteDoctor` for thin-client installs.
|
||||
- `engine` field on `GBrainConfig` stays as today (`postgres | pglite`) — thin-client mode is a separate code path, NOT an engine kind extension.
|
||||
|
||||
**New thin-client doctor** (`src/core/doctor-remote.ts`, ~180 LOC):
|
||||
|
||||
- Five outbound HTTP probes scoped to "is the remote MCP we configured actually reachable?": config_integrity (URL fields well-formed), oauth_credentials (secret resolvable), oauth_discovery, oauth_token, mcp_smoke. Output shape matches the local doctor's Check surface (`schema_version: 2`) so JSON consumers can union the two without conditional logic.
|
||||
|
||||
**New focused server-side doctor** (`src/commands/doctor.ts:doctorReportRemote`):
|
||||
|
||||
- Used by the new `run_doctor` MCP op for `gbrain remote doctor`. Five checks: connection (engine reachable), schema_version (current vs latest), brain_score (5-component composite), sync_failures (file-plane JSONL count), queue_health (Postgres-only stalled-job sweep). Engine-agnostic — uses `engine.executeRaw` + `engine.getConfig` + `engine.getHealth`. Local doctor (`runDoctor`) is unchanged; operators on the host still get the full check set.
|
||||
- New `DoctorReport` interface + `computeDoctorReport(checks)` exported for shared status/score math.
|
||||
|
||||
**New MCP op** (`src/core/operations.ts`):
|
||||
|
||||
- `run_doctor` (`scope: 'admin'`, `localOnly: false`, `mutating: false`) wraps `doctorReportRemote()` and returns the structured DoctorReport. First read-only diagnostic op exposed over HTTP MCP. Doctor only — generalizing to lint/integrity/orphans is filed as follow-up pending demand.
|
||||
|
||||
**New outbound HTTP MCP client** (`src/core/mcp-client.ts`, ~210 LOC):
|
||||
|
||||
- Wraps the official `@modelcontextprotocol/sdk` `Client` + `StreamableHTTPClientTransport` with OAuth `client_credentials` minting, in-process token caching (Map keyed by `mcp_url`, expires_at with 30s safety margin), and refresh-on-401 retry semantics. Initial-credentials-fail surfaces immediately as `RemoteMcpError(auth)` — retry only fires when a previously-good token gets rejected mid-session. Auth-fail-after-refresh produces a structured error pointing the operator at `gbrain auth register-client`.
|
||||
- Probe helpers in `src/core/remote-mcp-probe.ts` (`discoverOAuth`, `mintClientCredentialsToken`, `smokeTestMcp`) — pure `fetch`-based, no SDK dep, used by both init's setup smoke and the thin-client doctor.
|
||||
|
||||
**New documentation**:
|
||||
|
||||
- `docs/architecture/topologies.md` — three topology diagrams (single brain, cross-machine thin client, split-engine per-worktree) with concrete setup recipes. Honest about Topology 3's manual-alias routing (wrong alias = silent wrong-brain writes).
|
||||
- `skills/setup/SKILL.md` — new Phase A.5 walks the user through which topology fits before running `gbrain init`. Thin-client path skips Phases B/C/C.5/H entirely.
|
||||
|
||||
**Tests** (72 new test cases across 6 new files):
|
||||
|
||||
- `test/init-mcp-only.test.ts` (15 cases) — happy path, env-var-supplied secret stays out of disk, all four required-flag missing-error paths, three pre-flight smoke-failure paths, network-unreachable, four re-run-guard variants.
|
||||
- `test/cli-dispatch-thin-client.test.ts` (14 cases) — 9 refused commands × canonical error, 2 safe commands still work, doctor routes to runRemoteDoctor, regression for local config.
|
||||
- `test/doctor-remote.test.ts` (12 cases) — 5 thin-client checks against in-process HTTP fixture, every probe failure mode (404/parse/auth/network/server-error), env-var override of secret.
|
||||
- `test/doctor-report-remote.test.ts` (11 cases) — 5 PGLite checks, computeDoctorReport math.
|
||||
- `test/mcp-client.test.ts` (13 cases) — token cache, force-refresh, every error reason path, unpackToolResult parse failures.
|
||||
- `test/e2e/thin-client.test.ts` (7 cases against real Postgres + `gbrain serve --http`) — full cross-machine flow: init → doctor → sync refused → remote doctor → remote ping → re-run-guard → scope-mismatch regression.
|
||||
|
||||
All tests use async `Bun.spawn` for subprocess invocation rather than `execFileSync`, which deadlocks against in-process HTTP fixtures because the parent's event loop can't accept connections while sync-blocked.

# GBrain Deployment Topologies
|
||||
|
||||
GBrain supports three deployment shapes. They compose: a single user can mix
|
||||
all three on the same machine without conflict, because every shape resolves
|
||||
to "which `~/.gbrain/config.json` is active right now?" and `GBRAIN_HOME`
|
||||
controls that selection.
|
||||
|
||||
This page covers the three topologies, when each fits, and concrete setup
|
||||
recipes. Pair this doc with `docs/architecture/brains-and-sources.md` (which
|
||||
covers the in-brain organization axes) — that doc is about WHICH database;
|

Topologies 2 and 3 stack: a thin-client install can also host per-worktree

code engines, and a per-worktree code engine can also point its artifact
|
||||
brain at a remote server.
|
||||
|
||||
## Topology 1 — Single brain (today's default)
|
||||
|
||||
```

|
||||
```
|
||||
|
||||
What you get: one local DB (PGLite for small brains, Supabase for ~1000+
|
||||
files). All commands work directly against it. `gbrain serve` exposes it
|
||||
to a single agent over MCP.
|
||||
|
||||
When it fits: solo use, single machine, one agent, no Conductor parallelism.
|
||||
This is the default; `gbrain init` (no flags) gives you this.
|
||||
|
||||
Setup:
|
||||
|
||||
```
|
||||
gbrain init # interactive — defaults to PGLite
|
||||
gbrain init --pglite # explicit local
|
||||
gbrain init --supabase # remote Supabase (recommended for 1000+ files)
|
||||
```
|
||||
|
||||
Nothing else here is special. The other two topologies are variations on
|
||||
"who owns the DB" and "how does the agent talk to it."
|
||||
|
||||
## Topology 2 — Cross-machine thin client

|

```
|
||||
|
||||
What you get: the agent on one machine ("neuromancer") consumes a brain
|
||||
hosted on another machine ("brain-host") over HTTP MCP with OAuth. The
|
||||
agent's machine has NO local engine. All queries, searches, embeddings,
|
||||
and indexing happen on the host.
|
||||
|
||||
When it fits:
|
||||
|
||||
- Heavy brain (Supabase + autopilot) lives on a beefy machine; agents
|
||||
elsewhere just consume it.
|
||||
- You want one source of truth across many machines.
|
||||
- Spinning up a parallel local install would create source-ID contention or
|
||||
duplicate work.
|
||||
|
||||
The thin client's `~/.gbrain/config.json` carries a `remote_mcp` field
|
||||
instead of a local DB connection:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"engine": "postgres", // ignored — never used
|
||||
"remote_mcp": {
|
||||
"issuer_url": "https://brain-host.local:3001",
|
||||
"mcp_url": "https://brain-host.local:3001/mcp",
|
||||
"oauth_client_id": "neuromancer-...",
|
||||
"oauth_client_secret": "..." // or set GBRAIN_REMOTE_CLIENT_SECRET
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The CLI dispatch guard refuses any DB-bound command (`sync`, `embed`,
|
||||
`extract`, `migrate`, `apply-migrations`, `repair-jsonb`, `orphans`,
|
||||
`integrity`, `serve`) on a thin-client install with a clear error pointing
|
||||
at the remote host. `gbrain doctor` runs a dedicated thin-client check set
|
||||
(OAuth discovery, token round-trip, MCP smoke).
|
||||
|
||||
### Setup
|
||||
|
||||
**Step 1 — On the host (brain-host):**
|
||||
|
||||
```bash
|
||||
gbrain init --supabase # or --pglite, doesn't matter
|
||||
gbrain serve --http --port 3001 # exposes /mcp + OAuth
|
||||
gbrain auth register-client neuromancer \
|
||||
--grant-types client_credentials \
|
||||
--scopes read,write,admin # admin needed for ping/doctor
|
||||
```
|
||||
|
||||
The `register-client` command prints a `client_id` and `client_secret`.
|
||||
Note both. **Scope must include `admin`** — `submit_job` (used by
|
||||
`gbrain remote ping`) and `run_doctor` (used by `gbrain remote doctor`)
|
||||
both require it.
|
||||
|
||||
**Step 2 — On the thin client (neuromancer):**
|
||||
|
||||
```bash
|
||||
gbrain init --mcp-only \
|
||||
--issuer-url https://brain-host.local:3001 \
|
||||
--mcp-url https://brain-host.local:3001/mcp \
|
||||
--oauth-client-id <id> \
|
||||
--oauth-client-secret <secret>
|
||||
```
|
||||
|
||||
Pre-flight smoke runs three probes (OAuth discovery, token round-trip,
|
||||
MCP initialize). If any fails, init exits with an actionable error. On
|
||||
success, `~/.gbrain/config.json` gets `remote_mcp` set and NO local DB
|
||||
is created.
|
||||
|
||||
**Step 3 — Configure your agent's MCP client.**
|
||||
|
||||
For Claude Desktop / Hermes / openclaw, add a single MCP server entry
|
||||
pointing at the host's `mcp_url` with the bearer token from `register-client`.
|
||||
Example for Claude Desktop's `~/.config/claude/claude_desktop_config.json`:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"mcpServers": {
|
||||
"gbrain": {
|
||||
"type": "url",
|
||||
"url": "https://brain-host.local:3001/mcp",
|
||||
"headers": { "Authorization": "Bearer <client_secret>" }
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 4 — Verify.**
|
||||
|
||||
```bash
|
||||
gbrain doctor # runs thin-client checks (no local DB needed)
|
||||
gbrain remote ping # triggers an autopilot cycle on the host (Tier B)
|
||||
gbrain remote doctor # asks the host to run its own doctor (Tier B)
|
||||
```
|
||||
|
||||
`gbrain sync` and friends will refuse with a clear thin-client error
|
||||
naming the `mcp_url`. That's the correct behavior — those commands need
|
||||
a local engine that doesn't exist here.
|
||||
|
||||
### Re-run guard
|
||||
|
||||
Running `gbrain init` (no flags) on a machine that already has thin-client
|
||||
config set refuses without `--force`. This catches the scripted-setup-loop
|
||||
friction where an orchestrator keeps trying to create a local DB. Use
|
||||
`gbrain init --mcp-only --force` to refresh thin-client config.
|
||||
|
||||
### Storing the OAuth secret
|
||||
|
||||
Three storage paths in priority order:
|
||||
|
||||
1. **`GBRAIN_REMOTE_CLIENT_SECRET` env var** (preferred for headless agents).
|
||||
When set, overrides whatever's in the config file. The init flow doesn't
|
||||
persist a config-file copy when the env var was the source.
|
||||
2. **`~/.gbrain/config.json` with 0600 perms** (default for interactive
|
||||
setup; mirrors how Supabase keys are stored today).
|
||||
3. macOS Keychain integration is on the roadmap; not in v1.
|
||||
|
||||
## Topology 3 — Split-engine, per-worktree code + remote artifacts

|
||||
│ mcp__gbrain_artifacts__* → http://brain-host/mcp │
|
||||
└──────────────────────────────────────────────────────┘
|
||||
```
|
||||
|
||||
What you get: each Conductor worktree has its own per-worktree code index
|
||||
(local PGLite, disposable when the worktree dies). Artifacts (plans,
|
||||
learnings, transcripts) still live in a shared brain that all worktrees
|
||||
can see and write to.
|
||||
|
||||
When it fits:
|
||||
|
||||
- Multiple Conductor worktrees on one machine, all touching the same code
|
||||
repo.
|
||||
- You don't want each worktree's code-import to clobber the others'
|
||||
`last_commit`, source IDs, or symbol tables.
|
||||
- You DO want artifacts (plans, learnings, retros, transcripts) to be
|
||||
visible across worktrees.
|
||||
|
||||
### How it works
|
||||
|
||||
`GBRAIN_HOME` selects which `~/.gbrain` directory is active. Set per worktree:
|
||||
|
||||
```bash
|
||||
export GBRAIN_HOME=/path/to/worktree-A/.conductor/gbrain
|
||||
gbrain init --pglite
|
||||
gbrain serve --http --port 3001
|
||||
```
|
||||
|
||||
Each worktree's `gbrain serve` instance binds its own port and indexes its
|
||||
own DB. Multiple `gbrain serve` processes coexist fine — they're separate
|
||||
OS processes with separate config and separate connection pools.
|
||||
|
||||
The artifact brain runs as a separate `gbrain serve` instance with the
|
||||
default `~/.gbrain` (no GBRAIN_HOME override) — or remote, in which case
|
||||
it's a Topology 2 setup.
|
||||
|
||||
The agent's MCP client config lists multiple servers, each with a unique
|
||||
alias. Tool names are namespaced as `mcp__<alias>__<tool>`, so the agent
|
||||
calls `mcp__gbrain_code__search` for code lookups and `mcp__gbrain_artifacts__search`
|
||||
for artifact lookups.
|
||||
|
||||
### CRITICAL: alias-level routing is manual
|
||||
|
||||
Topology 3 has no smart per-tool routing inside gbrain. The agent picks
|
||||
which brain to query when it picks the alias. **A wrong alias writes (or
|
||||
queries) the wrong brain silently.** This is intentional (explicit beats
|
||||
magic) but real:
|
||||
|
||||
- If the agent calls `mcp__gbrain_artifacts__put_page` with code-shaped
|
||||
content, that page lands in the artifact brain forever.
|
||||
- If the agent calls `mcp__gbrain_code__search` for a question that
|
||||
actually wants artifact context, the search comes back empty.
|
||||
|
||||
Mitigations:
|
||||
|
||||
- Name aliases clearly. `gbrain_code` vs `gbrain_artifacts` is unambiguous;
|
||||
`gbrain` vs `gbrain_local` is not.
|
||||
- Document in your agent's system prompt or rules which alias goes where.
|
||||
Be explicit about "code questions → `gbrain_code`; everything else →
|
||||
`gbrain_artifacts`."
|
||||
- Pair Topology 3 with `gstack`'s per-worktree wiring (which sets the
|
||||
alias names + agent rules consistently across worktrees).
|
||||
|
||||
### Setup (manual; gstack automates this side)
|
||||
|
||||
The gbrain side requires zero new code — `GBRAIN_HOME` and `--port` already
|
||||
exist. Setup looks like:
|
||||
|
||||
```bash
|
||||
# Start the artifact brain (default ~/.gbrain) on port 3000
|
||||
gbrain serve --http --port 3000 &
|
||||
|
||||
# Start a per-worktree code brain on port 3001
|
||||
export GBRAIN_HOME=/path/to/worktree-A/.conductor/gbrain
|
||||
gbrain init --pglite
|
||||
gbrain serve --http --port 3001 &
|
||||
unset GBRAIN_HOME
|
||||
```
|
||||
|
||||
Then configure the agent's MCP config with two entries (different aliases,
|
||||
different ports). For Claude Desktop:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"mcpServers": {
|
||||
"gbrain_artifacts": {
|
||||
"type": "url",
|
||||
"url": "http://localhost:3000/mcp",
|
||||
"headers": { "Authorization": "Bearer <token-A>" }
|
||||
},
|
||||
"gbrain_code": {
|
||||
"type": "url",
|
||||
"url": "http://localhost:3001/mcp",
|
||||
"headers": { "Authorization": "Bearer <token-B>" }
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The gstack-side wiring (per-worktree home setup, port allocation, automatic
|
||||
MCP config generation, gitignore for the per-worktree DB) is in the gstack
|
||||
repo's setup-gbrain skill — it composes these primitives, gbrain doesn't
|
||||
have to know about Conductor.
|
||||
|
||||
## Combining topologies
|
||||
|
||||
The three shapes compose. A single machine can run:
|
||||
|
||||
- A thin-client default config pointing at a remote artifact brain
|
||||
(Topology 2).
|
||||
- Plus per-worktree code brains under their own `GBRAIN_HOME` (Topology 3).
|
||||
- Each worktree's `gbrain serve` instance is local; the agent's MCP config
|
||||
lists them alongside the remote artifact brain.
|
||||
|
||||
`GBRAIN_HOME` controls which config file is active for any one CLI
|
||||
invocation. `gbrain serve --port` controls which port a server listens on.
|
||||
The agent's MCP client picks the alias and thus the destination per tool
|
||||
call. There's no global gbrain orchestrator that knows about all of them
|
||||
simultaneously — that's by design.
|
||||
|
||||
## When NOT to use these topologies
|
||||
|
||||
- **Don't use Topology 2 if your agent only ever runs on the same machine
|
||||
as the brain.** A local `gbrain` install + `gbrain serve` (stdio) is
|
||||
simpler and faster.
|
||||
- **Don't use Topology 3 if you only have one Conductor worktree at a
|
||||
time.** Per-worktree engines exist to prevent contention; one-at-a-time
|
||||
use has no contention.
|
||||
- **Don't use a `remote_mcp` thin client AND a local engine on the same
|
||||
machine in the same `GBRAIN_HOME`.** The dispatch guard refuses DB-bound
|
||||
commands when `remote_mcp` is set. If you genuinely want both modes on
|
||||
one machine, use `GBRAIN_HOME` to separate them (one home for the thin
|
||||
client, another for the local engine).

|

## Phase A.5: Choose Topology (run BEFORE Phase A)
|
||||
|
||||
GBrain supports three deployment shapes. Pick the right one before installing,
|
||||
because picking wrong creates contention or duplicate work that's painful to
|
||||
unwind. Read `docs/architecture/topologies.md` for the full picture; the short
|
||||
version:
|
||||
|
||||
Ask the user this BEFORE running `gbrain init`:
|
||||
|
||||
> "Three deployment shapes:
|
||||
> 1. **Single brain (default)** — one machine, one DB, one agent. Pick this if
|
||||
> unsure.
|
||||
> 2. **Cross-machine thin client** — your brain lives on another machine
|
||||
> (e.g. brain-host) running `gbrain serve --http`, and this install just
|
||||
> calls it over MCP. No local DB on this machine.
|
||||
> 3. **Per-worktree code + shared remote artifacts** — Conductor users with
|
||||
> multiple worktrees indexing the same code repo. Each worktree owns its
|
||||
> own code engine; artifacts live on a shared remote brain.
|
||||
>
|
||||
> Which fits?"
|
||||
|
||||
### If the user picks 1 (single brain) — proceed to Phase A
|
||||
|
||||
Continue with the existing `gbrain init --supabase` / `--pglite` setup below.
|
||||
|
||||
### If the user picks 2 (cross-machine thin client)
|
||||
|
||||
1. **Confirm a host already exists.** Ask: "Is the remote `gbrain serve --http`
|
||||
already running on the host machine?" If no, the user needs to set up the
|
||||
host first (Phases A-C on the host, then `gbrain serve --http`). Don't try
|
||||
to run init on this machine until the host is up.
|
||||
|
||||
2. **Get OAuth credentials from the host operator.** Ask the user to run
|
||||
on the host:
|
||||
```bash
|
||||
gbrain auth register-client <name> \
|
||||
--grant-types client_credentials \
|
||||
--scopes read,write,admin
|
||||
```
|
||||
The `admin` scope is required because `gbrain remote ping` and
|
||||
`gbrain remote doctor` (Tier B convenience commands) call MCP ops with
|
||||
`admin` scope. `read,write` alone breaks ping/doctor.
|
||||
|
||||
3. **Run thin-client init on this machine:**
|
||||
```bash
|
||||
gbrain init --mcp-only \
|
||||
--issuer-url https://<host>:<port> \
|
||||
--mcp-url https://<host>:<port>/mcp \
|
||||
--oauth-client-id <id> \
|
||||
--oauth-client-secret <secret>
|
||||
```
|
||||
Or set `GBRAIN_REMOTE_CLIENT_SECRET` env var instead of the flag (preferred
|
||||
for headless / scripted setup). Pre-flight runs three smoke probes; any
|
||||
failure surfaces an actionable error.
|
||||
|
||||
4. **Configure your agent's MCP client.** Add a server entry pointing at
|
||||
`<mcp_url>` with the bearer token. See `docs/mcp/CLAUDE_DESKTOP.md`,
|
||||
`docs/mcp/CLAUDE_CODE.md`, etc. for per-client snippets.
|
||||
|
||||
5. **Verify with `gbrain doctor`.** Thin-client doctor runs OAuth discovery,
|
||||
token round-trip, and MCP smoke against the host. Should report
|
||||
`mode: thin-client` with all checks green.
|
||||
|
||||
6. **Skip Phases B, C, C.5, and H entirely.** They're for local engines.
|
||||
The host's autopilot handles sync/extract/embed. Thin clients consume
|
||||
only.
|
||||
|
||||
7. **Continue to Phase D (brain-first lookup).** It works identically over
|
||||
MCP — the agent uses the same brain-ops skill to query/search/get_page,
|
||||
they just round-trip through the host's `gbrain serve --http`.
|
||||
|
||||
If init reports "thin-client config already present", a previous setup
|
||||
already configured this machine. Refusing without `--force` is the correct
|
||||
behavior; either accept the existing config or pass `--force` to refresh.
|
||||

||||
### If the user picks 3 (split-engine per-worktree)
|
||||
|
||||
This shape requires per-worktree wiring that gstack handles, not gbrain
|
||||
directly. gbrain's role is just to run a local engine when `GBRAIN_HOME` is
|
||||
set — that already works.
|
||||
|
||||
Point the user at `docs/architecture/topologies.md` (the Topology 3 section)
|
||||
for the wiring recipe, then continue with Phase A as normal — `gbrain init`
|
||||
on this machine sets up the artifact brain (the "default" home). The
|
||||
per-worktree code engines are configured per-worktree as gstack creates them.
|
||||
|
||||
If the user has a remote artifact brain (Topology 2 + 3 combined), follow
|
||||
the thin-client setup above for the artifact brain instead of Phase A.

* amortizes when a single `gbrain remote ping` makes multiple calls (submit_job
|

||||
*
|
||||
* First read-only diagnostic op exposed over HTTP MCP. Wraps the focused
|
||||
* thin-client check set in `src/commands/doctor.ts:doctorReportRemote()` and
|
||||
* returns the structured `DoctorReport` JSON verbatim. The matching client-
|
||||
* side renderer lives in `src/commands/remote.ts` (used by `gbrain remote
|
||||
* doctor`). Local doctor is unchanged — operators on the host still get the
|
||||
* full check set.
|
||||
*
|
||||
* scope=admin because some checks expose system-state (queue depth, schema
|
||||
* version) that read-only consumers don't need. localOnly=false so HTTP
|
||||
* callers can invoke it. No mutation; safe to call repeatedly.
|
||||
*
|
||||
* Precedent: doctor only. Generalizing to lint/integrity/orphans is filed as
|
||||
* follow-up work pending demand.

* The /mcp fixture implements just enough JSON-RPC to satisfy

* StreamableHTTPClientTransport's connect handshake (initialize + initialized
|

* notification) plus tools/call. NOT a full MCP server — only the surface
|

* area a client_credentials thin-client uses.
|

*
|

* Async Bun.spawn-friendly: the test event loop stays responsive during
|
||||
* fetch round-trips because callRemoteTool awaits async work properly.
