Reduce the default external-MCP silence timeout from 5 min to 1 min and the
overall call timeout from 15 min to 2 min. Update related tests and comments.
Increase Fastify's JSON body limit to 25 MiB (configurable via
HTTP_JSON_BODY_LIMIT) to accommodate large AI‑chat payloads.
BREAKING CHANGE: shorter MCP timeouts may abort long‑running tool calls that
previously succeeded with the older defaults.
The resumable-SSE run-stream registry (PR #386/#387) ships behind the
server-side AI_CHAT_RESUMABLE_STREAM env flag, OFF by default: with the
flag off attach always answers 204 and reopened tabs of an active run
fall back to degraded history polling. Document the flag, its default,
its relation to the per-workspace autonomousRuns setting, and the
single-instance constraint in .env.example next to the autonomous-runs
section.

Maintainer resolved E1 as variant B: the public vitals sink + client collection
must be OFF by default (else client_metrics grows unbounded on a self-host deploy
with no external pruner, via an unauthenticated public endpoint).
- F1: new operator flag CLIENT_TELEMETRY_ENABLED (default OFF), SEPARATE from
METRICS_PORT (Grafana reads the table directly, independent of the scrape port).
ClientTelemetryModule.register() provides VitalsController ONLY when the flag is
true (route absent otherwise); the flag reaches the client via window.CONFIG
(config.ts isClientTelemetryEnabled), and initVitals() early-returns when off.
- F2/F3 [throttler]: this repo's ThrottlerGuard applies EVERY named throttler to
every guarded route unless skipped. The new VITALS bucket therefore (a) newly
bound collab-token → 429 behind shared/NAT IPs, and (b) the vitals route didn't
skip the stricter public-share-ai (5/min) bucket → effective 5/min not 120.
Fix (additive, global config unchanged): vitals.controller @SkipThrottle the
other buckets + @Throttle VITALS 120/min; collab-token adds VITALS_THROTTLER to
its existing @SkipThrottle (restoring its prior effectively-unthrottled state).
- F4: metrics node:http server is closed on shutdown (MetricsServerLifecycle
OnModuleDestroy → closeMetricsServer(), fired by enableShutdownHooks).
- F5: docSize outside [0, int4-max] drops to null (keeping the event) instead of
overflowing int4 and failing the WHOLE batch insert (+ 2 tests).
- F6: .env.example documents METRICS_PORT (no default — unset = subsystem OFF) +
CLIENT_TELEMETRY_ENABLED; fixed the inaccurate "default 9464" wording.
- F7: disabled/non-sampled sessions install ZERO observers — isVitalsActive()
(enabled && sampled) gates reportClientMetric AND the page-editor
measurePageOpen + dispatchTransaction wrapping.
- F8: kept db.d.ts hand-added (wontfix) — this repo HAND-CURATES db.d.ts (verified
across recent fork migrations a32fba63/8c5b57eb/fdeede00); codegen would be the
deviation. The ClientMetrics interface maps the migration 1:1.
Gate: server tsc 0, client tsc 0, server metrics/vitals/telemetry/throttle 21
tests, client route-template 5. No new deps.

Squashed for a clean rebase onto develop (was 19 commits; the reviewer approved
the net diff at fb246080). Detaches an agent run from the HTTP request/browser
window: a run is a first-class lifecycle object (ai_chat_runs), a browser
disconnect no longer kills it, a concurrent-run insert-gate prevents double runs,
and a reopened chat live-follows a still-running run via a polled observer merge.

- F1: document AI_CHAT_DEFERRED_TOOLS in .env.example (AI_* section) — default
ON = deferred loading (compact catalog + loadTools), =false restores the old
"all tools always active" behavior.
- F2: integration test of the ON path in ai-chat-stream.int-spec.ts — a deferred
tool activated via loadTools is active on the SAME turn's next step but a fresh
turn starts cold (CORE + loadTools only), proving the per-turn activatedTools
Set does not leak across turns/chats. Drives the real streamText loop with a
MockLanguageModelV3 and inspects recorded per-step activeTools-filtered tools.
- F3: replace the magic toHaveLength(28) in tool-tiers.spec.ts with a two-way
partition against the LIVE in-app toolset (AiChatToolsService.forUser keys):
every non-core tool must appear in buildInAppDeferredCatalog and every catalog
entry must map to a real non-core tool — so a future tool forgotten in
INLINE_TOOL_TIERS fails the suite instead of silently vanishing from the agent.
No production logic change (mechanism was already reviewed correct).

In prod the AI provider resets the connection pre-response (ECONNRESET); the
#175 pre-response retry recovers it, but 2 of the 3 allowed attempts were burned
in a single turn — no headroom, and one more reset would surface an error to the
user. This is tuning for resilience (not a diagnosis of who resets):
- Retry budget 2 → 4 (total 5 attempts), env-configurable via
AI_STREAM_PRE_RESPONSE_RETRIES (0 = no retry; empty/invalid → default 4).
- Backoff: linear 150*(attempt+1) → capped exponential + full jitter
(preResponseBackoffMs, a pure injectable helper): base 150ms, ×2 per attempt,
capped 2000ms, delay = random in [0, capped]. Avoids a synchronized retry
storm and spreads reconnects across the reset window.
- Keep-alive default 10_000 → 4_000 ms so undici recycles idle sockets before a
~5s upstream/middlebox idle cutoff can poison them (a common pre-response
reset cause). Still env-overridable via AI_STREAM_KEEPALIVE_MS.
- .env.example documents both knobs.
Timeout (900s), RETRYABLE_CONNECT_CODES, and the instrumentation are unchanged.

Security:
- stash_page: reject path-traversal / percent-encoded srcs before the authed
loopback fetch (resolveInternalFilePath), closing an SSRF/exfiltration hole
where a crafted node.attrs.src could read an arbitrary internal GET endpoint
into the anonymous sandbox.
Stability:
- stash_page: revert + recount mirrors FIFO-evicted by a later put in the same
stash (no dangling sandbox refs, honest images.mirrored/failed); free image
blobs if the final document put throws.
- Reject/clamp non-positive SANDBOX_TTL_MS to the 1h default (warn once).
- Log mirror failures unconditionally (console.warn, no blob bodies).
Cleanup / architecture:
- Remove dead expiresAt from SandboxPutResult.
- Centralize the /api/sb route in SANDBOX_ROUTE_SEGMENT/SANDBOX_API_PATH and
move URL composition into SandboxStore.putAndLink; drop the duplicated sink
closures and the now-unused EnvironmentService injection from McpService and
AiChatToolsService.
- Un-export isInternalFileUrl; document the process-local (instance-bound)
sandbox limitation in the tool description and .env.example.
Docs/tests:
- README/README.ru: 38 -> 39 tools + stash_page entry.
- Add traversal/normalize/recursion unit tests, stash self-eviction +
doc-put-throw + empty/octet-stream mock tests, controller If-None-Match
(wildcard/weak/list) + Cache-Control tests, and SANDBOX_TTL_MS validation
tests. Regenerate packages/mcp/build.

Add an ephemeral, process-local blob store so the in-app agent (and the
embedded MCP) can hand a large page document and its images to an external
consumer WITHOUT routing the bytes through the model context or Docmost auth.
- SandboxStore (@Injectable singleton): Map<uuid,{buf,mime,sha256,expiresAt}>
in RAM only. put() picks a per-blob cap by mime (image vs doc), enforces a
total-bytes RAM guard with oldest-first eviction, and stamps a TTL; get()
lazily expires. sha256 computed at put() doubles as the strong ETag. An
unref'd sweep interval clears expired entries and is cleared on destroy.
- GET /api/sb/:uuid anonymous controller: serves raw bytes with Content-Type,
Content-Length and ETag=sha256; 404 on missing/expired/non-UUID (anti-
traversal), 304 on a matching If-None-Match. No tokens, no 401 — the
capability is the unguessable UUID + short TTL + TLS. Auth-exempt the same
way as /api/files/public (no JwtAuthGuard) plus an /api/sb entry in main.ts's
workspace-resolution preHandler so a remote consumer with no workspace host
is not rejected.
- stash_page tool in both layers (MCP resource_link + in-app {uri,size,sha256,
images}). client.stashPage serializes the get_page_json shape, mirrors every
INTERNAL file/image src (type-agnostic, covers drawio/excalidraw/video/file)
into the sandbox under Docmost auth and rewrites src to the sandbox URL;
external http(s) srcs are left untouched; dedup by src; a failed image fetch
is counted, never aborts the doc.
- SANDBOX_PUBLIC_URL / SANDBOX_TTL_MS / SANDBOX_MAX_BYTES /
SANDBOX_MAX_IMAGE_BYTES / SANDBOX_MAX_TOTAL_BYTES wired through the
environment service + validation + .env.example.
- SandboxModule (@Global) provides the shared store to the controller,
McpService and AiChatToolsService (same instance for put and get).
Tests: SandboxStore (round-trip, sha256, TTL lazy + sweep, caps, eviction),
SandboxController (200+ETag+CT+CL, 404 missing/expired/non-UUID, 304), and a
mock-HTTP stashPage test (mirror+rewrite internal, keep external, dedup, failed
image counted, returns only a link). Interoperates with the vvzvlad/habr-mcp
consumer's anonymous-GET + sha256-ETag + resource_link contract.

The agent-roles catalog content files move from JSON to YAML so each role's long
`instructions` system prompt is stored as a literal block scalar (`|-`): editing
one sentence now produces a line-by-line diff and the prompt is editable as plain
multi-line text instead of a single escaped JSON string.
Data:
- `index.json` -> `index.yaml`, `bundles/<id>/<lang>.json` -> `<lang>.yaml`
(old `.json` deleted). Converted programmatically via the `yaml` library with
`lineWidth: 0`; round-trip verified deepEqual against the old JSON, so the
resolved role content is byte-for-byte identical (the only `version` bump is
fact-checker v2->3, carried over from develop during the rebase; see below).
Server (`AiAgentRolesCatalogProvider`):
- parse with `yaml`'s safe default (JSON-compatible) schema instead of
`JSON.parse` — `strict: true` (rejects duplicate keys) and `maxAliasCount: 100`
(billion-laughs guard); no custom `!!` tags / no code execution. Fetched paths
become `index.yaml` / `<lang>.yaml`. The streaming 1 MB size cap,
`redirect: 'error'`, 10s timeout and `^[a-z0-9-]+$` path-traversal/SSRF guard
are unchanged; the hand-written type guards are untouched (`instructions` is
still a string after parsing).
- add `yaml` as a direct server dependency (already in the lockfile as a
transitive dep).
Catalog tooling:
- `scripts/check.mjs` parses the catalog as YAML (lockfile stays JSON); pin
`yaml` as a devDependency of the catalog package.
Tests:
- provider spec fixtures serialized with `yaml`; new tests for the block-scalar
`instructions` round-trip (exact multi-line string), malformed YAML and
strict duplicate-key rejection -> BadGateway; size-cap and path-traversal
cases retargeted to the `.yaml` paths.
Docs: README, `.env.example`, `catalog-types.ts` comments and CHANGELOG updated
to the YAML layout. `AI_AGENT_ROLES_CATALOG_URL` base-URL contract unchanged.
Rebase onto develop + review (PR #231, comment 2509):
- semantic conflict: develop's 89edddc5 bumped fact-checker v2->3 (flags errors
instead of confirming facts) in the now-deleted `.json`. Resolved the
modify/delete by taking the deletion and porting develop's v3 `description` +
`instructions` (en + ru) into the YAML and setting `version: 3` in index.yaml.
Verified by `node scripts/check.mjs` going green against develop's unchanged
content-hash lock (the ported YAML hashes byte-identically to the v3 JSON).
- doc fix: ai-agent-roles.service.ts catalog comment "untrusted JSON" -> YAML.
- doc fix: parseYaml docstring no longer claims `strict: true` rejects unknown
custom tags (yaml@2.8.x warns + resolves to a plain scalar, then the type
guard rejects it); the duplicate-key claim is kept.
- doc: note in check.mjs that `yaml` resolves from the repo-ROOT node_modules
(via shamefully-hoist), not the catalog package's own pinned devDependency.

The agent-roles catalog source is no longer hardcoded in app code and no
longer supports a local filesystem directory. The provider now fetches only
from an http(s):// base URL read from AI_AGENT_ROLES_CATALOG_URL; an empty or
non-http value yields a 502 (catalog unavailable). The default URL is baked
into the Docker image at build time and set per branch in CI.
- provider: drop readLocal + node:fs/node:path; readRelative requires http(s)
and 502s otherwise; remote fetch/streaming-cap/SSRF guards unchanged.
- environment.service: keep AI_AGENT_ROLES_CATALOG_URL (default ''); comment
updated to reflect build-time injection, remote-only.
- Dockerfile: add ARG+ENV AI_AGENT_ROLES_CATALOG_URL in the installer stage.
- CI: develop.yml builds with the develop raw URL; release.yml (both build
steps) with the main raw URL.
- tests: replace local-fixture tests with remote-mock happy/malformed bundle
tests and a non-http => 502 case; path-traversal block uses an https source.
- docs: update .env.example, CHANGELOG (#222), agent-roles-catalog/README.

Admins can browse a curated catalog of agent roles, import roles/bundles
into a workspace, and update an imported role when the catalog ships a
newer version.
Catalog: a set of JSON files (index.json manifest + bundles/<id>/<lang>.json)
served from a local folder (dev) or a remote http(s) base URL via
AI_AGENT_ROLES_CATALOG_URL. Seeded with the existing 7 RU roles (editorial +
research bundles) plus EN translations.
Server:
- migration: nullable jsonb `source` column on ai_agent_roles
({ slug, language, version }; null => manually created)
- catalog provider: remote fetch with timeout + streaming size cap, or local
read; ^[a-z0-9-]+$ segment guard against path-traversal/SSRF
- admin endpoints: catalog, catalog/bundle, import, update-from-catalog
- import/update match by slug+language; update preserves `enabled`
Client:
- catalog modal with language selector and Import/Installed/Update states
- "Import from catalog" button + empty-state CTA in the roles settings panel
- en-US/ru-RU strings

External MCP tools (web search, crawl) had no per-call timeout: a hung
tool call was only broken by the 15-min transport silence timeout shared
with the chat provider, and a server that kept the socket warm but never
returned could spin until the user cancelled.
Add two independent, composing bounds for external MCP traffic (the chat
provider path is unchanged):
- Silence 5 min: buildPinnedDispatcher now overrides headersTimeout/
bodyTimeout with mcpStreamTimeoutMs() (AI_MCP_STREAM_TIMEOUT_MS,
default 300000) on the external-MCP dispatcher only, so a byte-silent
upstream is severed in ~5 min instead of 15.
- Total per-call 15 min: wrapToolWithCallTimeout wraps each external
tool's execute with a fresh AbortController + timer composed with the
turn signal via AbortSignal.any (AI_MCP_CALL_TIMEOUT_MS, default
900000). It RACES the call against the abort signal because
@ai-sdk/mcp does not settle its in-flight promise on abort, so a
warm-but-stuck call would otherwise hang forever.
On timeout the call surfaces as a tool-error and the agent loop recovers.
Add tests (incl. a never-settling real-client-style stub) and document
both env vars in .env.example.
The real cause of the long-task "Lost connection to the AI provider" — the
earlier 300s-timeout fix (#176) was the wrong layer. The provider-HTTP telemetry
on the user's deploy shows the failures are PRE-RESPONSE `read ECONNRESET` ~500ms
in (not a 300s/15min timeout), correlated with idleSincePrevCall ~42s and large
bodies; and crucially a retry of the SAME request often succeeds. A direct probe
to the real z.ai endpoint does NOT reset (113KB bodies and a 45s-idle keep-alive
reuse both succeed), and another agent (opencode) runs fine from the same infra —
so the provider is healthy and the egress network is usable. The difference is
the transport: undici's keep-alive pool REUSES a socket that the deployment's
egress (NAT / firewall / conntrack) silently dropped during a long idle gap, so
the next request resets pre-response.
Fix (brings gitmost in line with clients that don't reuse stale sockets):
- Keep-alive recycling: the streaming dispatcher (chat fetch AND the external-MCP
dispatcher, via the shared streamingDispatcherOptions) now sets
keepAliveTimeout + keepAliveMaxTimeout to a 10s recycle window
(AI_STREAM_KEEPALIVE_MS), so a connection idle longer than that is closed
instead of reused — a long-gap step opens a fresh connection. keepAliveMaxTimeout
also caps a server-advertised keep-alive so the provider can't widen the window.
- Pre-response connection retry: createStreamingFetch retries a connection-level
reset (ECONNRESET / UND_ERR_SOCKET / ECONNREFUSED / EPIPE / *_TIMEOUT) on a
fresh connection up to 2 times. This is SAFE because fetch() only rejects before
the Response resolves — a started stream is never replayed; an abort (client
disconnect) is never retried.
Tests: ai-streaming-fetch.spec — keep-alive options, streamKeepAliveMs env,
isRetryableConnectError, and a server that resets the first connection so the
retry must land on a fresh one (+ aborted requests are not retried). Verified on
the stand that a normal turn still streams (reasoning + text + finish) through the
new transport. server tsc + ai/mcp specs green.
Note: root cause is the deployment's egress dropping idle connections (Traefik is
inbound-only); this makes the app resilient to it. AI_STREAM_KEEPALIVE_MS can be
lowered if the egress drops faster than ~10s.

- Wording: every comment now says the stream timeouts are RAISED to a
generous-but-finite ~15-min silence timeout, not "disabled (0)" (the stale
comments contradicted the code, which uses AI_STREAM_TIMEOUT_MS, default
900000ms).
- Architecture (the load-bearing-temporary trap): the streaming fetch reached
the chat provider only by riding the "temporary DIAGNOSTIC" telemetry, so
deleting the telemetry by its own label would silently revert the timeout fix.
Legitimize it: rename ai-http-diagnostics.ts -> ai-provider-http.ts,
createDiagnosticFetch -> createInstrumentedFetch, field aiDiagnosticFetch ->
aiProviderFetch, drop the "temporary" labels, and document the chat transport
(streaming fetch + instrumentation) as one intentional construct.
- Docs: AI_STREAM_TIMEOUT_MS added to .env.example next to AI_EMBEDDING_TIMEOUT_MS.
- Tests:
- ai-provider-http.spec: createInstrumentedFetch delegates to the injected
baseFetch with the same input/init, returns the Response untouched, rethrows
the error, and defaults to global fetch — covering the baseFetch seam.
- ai-streaming-fetch.spec: the delayed-server test is now LOAD-BEARING — with
AI_STREAM_TIMEOUT_MS set below the 1.5s server delay the call actually rejects
(a lost dispatcher -> global 300s default would NOT), proving the configured
dispatcher is wired; plus the default-timeout happy path.
server tsc clean; ai-streaming-fetch / ai-provider-http / ai.service / mcp-servers
/ ai-error specs green (41).

- [warn 1] Document the is_agent operator setup so it survives plan deletion:
added an AI-agent block to .env.example (use a DEDICATED account, set is_agent
via SQL, never flag a human/shared account) + a CHANGELOG "Added" entry.
- [warn 2] Test the badge deep-link side effects: ai-agent-badge.test.tsx now
renders inside an explicit jotai store, clicks the badge, and asserts the
active chat id, window-open, cleared draft, closed history modal, AND that
stopPropagation keeps a parent onClick from firing.
- [suggestion 3] Hoist the window.matchMedia stub into vitest.setup.ts and drop
the duplicated beforeAll block from the three test files (ai-agent-badge,
comment-list-item, role-cards).
- [suggestion 4] Merge the two near-duplicate "non-clickable" cases via it.each.
- [follow-up 6] Introduce a single ProvenanceSource = 'user' | 'agent' type in
jwt-payload.ts and reference it from AuthProvenanceData, JwtPayload/
JwtCollabPayload, and resolveSource() — so a typo can't slip through as a bare
string. (Server auth chain; client IComment mirroring left as a follow-up.)
Follow-up 5 (shared agentSourceFields write-stamp helper) is deferred as the
review marked it — the 6 REST sites use varied shapes (create-spread vs
resolve-conditional-null vs page move), so it's a separate focused refactor.
Tests: client badge/comment/role-cards suites 11/11 pass; server auth+comment
suites 62 pass; typecheck clean.

The custom undici RetryAgent + aiFetch transport added for issue #140
did not actually heal mid-stream provider drops: undici's retry path is
a Range-based download-resume that SSE/chat-completions endpoints cannot
satisfy, so a reset after the first byte only swapped ECONNRESET for a
"server does not support the range header" error. Its only real effect
was reconnecting a poisoned keep-alive socket before the first byte, and
PR #141 on top of it turned the 60s headers timeout into deterministic
~61s failures (plus CONTENT_LENGTH_MISMATCH from retrying a POST body
after a timeout abort). The root cause is the z.ai coding endpoint, not
our transport.
Remove the whole layer and return all AI provider calls to Node's
default global fetch.
- delete integrations/ai/ai-http.ts and its spec
- ai.service.ts: drop the aiFetch import, the AI_BYPASS_RESILIENT_FETCH

The streaming chat turn hangs in all browsers while the non-streaming test
endpoint works — both use the same model/transport (createOpenAI + aiFetch),
so the suspect is the streaming path / custom undici RetryAgent transport.
- ai-http.ts: wrap aiFetch with per-request timing logs (start, ms-to-headers
on success, elapsed ms + cause on failure). Chat at info, embeddings at
debug. Only host+path logged.
- ai-chat.controller.ts / ai-chat.service.ts: log turn START, first-chunk
latency, FINISHED duration, and elapsed ms on disconnect/error/abort.
- ai.service.ts: AI_BYPASS_RESILIENT_FETCH=true makes the CHAT model omit
fetch:aiFetch and use the default global fetch — isolates transport vs
request-shape. Chat-only; embeddings/STT untouched; reversible via env.
- .env.example: document the flag.
No timeout/retry change. tsc clean; ai-chat + ai suites pass (292).
The fail-closed limiter behavior (#62 primary item) already shipped; this
finishes the issue by lowering the default hourly per-workspace cap from 300
to 100 to better fit real anonymous-assistant load. Still overridable via
SHARE_AI_WORKSPACE_MAX_PER_HOUR.
- public-share-workspace-limiter.ts: SHARE_AI_WORKSPACE_MAX_PER_WINDOW 300 -> 100.
- .env.example: documented default + example value 300 -> 100.
- public-share-chat.spec.ts: update the default-cap assertion to 100.

trustProxy was unconditionally true, so req.ip came from a client-forgeable
X-Forwarded-For and the per-IP throttles (share-AI, /mcp brute-force) were
spoofable. Make it env-configurable (TRUST_PROXY) with a safe default that
trusts XFF only from loopback/private proxies, documented in .env.example.
NOTE: this changes the default from trust-all; deployments whose proxy is on a
public IP must set TRUST_PROXY (caveat documented).

Harden the anonymous public-share AI assistant against token-cost abuse
before exposing it to the internet:
- Add an env-tunable per-request output ceiling (maxOutputTokens) to the
public-share streamText call so one anonymous request cannot run up the
provider bill even if the per-IP throttle is evaded. New
resolveShareAiMaxOutputTokens() / SHARE_AI_MAX_OUTPUT_TOKENS_DEFAULT
(env SHARE_AI_MAX_OUTPUT_TOKENS, default 512), mirroring
resolveShareAiWorkspaceMax().
- Flip the per-workspace cost limiter to FAIL CLOSED on Redis failure
(was fail-open): if Redis is unavailable we cannot prove the workspace is
under its cap, so deny rather than admit an unmetered, billable call.
- Update the limiter spec (fail-open -> fail-closed) and add resolver tests;
document both knobs in .env.example.

Post-merge hardening from the #13 security review:
- isInitializeRequestBody now delegates to the SDK isInitializeRequest (same
predicate as packages/mcp/http.ts), so a bare {method:'initialize'} with no
id/params no longer triggers the side-effecting login() (audit-spam /
user_sessions growth) before http.ts 400s it.
- Bind the Bearer path to the instance workspace: verifyBearerAccess rejects a
token whose payload.workspaceId != the instance workspace (resolved via
workspaceRepo.findFirst, consistent with the Basic path); optional param so
it's a no-op when unset.
- Close the user-enumeration timing oracle in verifyUserCredentials: the
missing/disabled branch now runs a bcrypt compare against a module-level dummy
hash whose cost (12) matches production saltRounds, so both paths take one
equal-cost bcrypt compare; the exact CREDENTIALS_MISMATCH_MESSAGE is preserved.
- Document the trusted-proxy requirement for the spoofable per-IP brute-force
limiter in .env.example (trustProxy is on; deploy behind a trusted proxy).
- Add real-execution coverage for enforceBasicLoginGate (SSO enforced / EE-MFA
bundled vs not / user-MFA / workspace-enforced-MFA) instead of stubbing the gate.

The embedded MCP server acted as a single service account; now each /mcp
session authenticates as the current user, so tools run under that user's
CASL and edits attribute to them.
- HTTP Basic (chosen path): Authorization: Basic email:password, validated
server-side via AuthService; the session carries the issued user JWT (not
the raw password). Password may contain ':' (split on first only).
- Bearer fallback: Authorization: Bearer <access JWT>, verified as ACCESS and
additionally checked for an active session + non-disabled user (matching
JwtStrategy), so revoked/disabled users are rejected.
- Service account stays as an optional fallback (no creds + env configured).
- packages/mcp createMcpHttpHandler accepts a per-request config resolver
(back-compat: static config / stdio unchanged); identity is bound to the
mcp-session-id at init and re-validated from the caller's own credentials on
every request (anti session-fixation: a guessed session id can't be reused
without matching creds).
- A full login (session + audit) happens only once at session init; later
requests re-verify credentials via a new non-side-effecting
AuthService.verifyUserCredentials (no session/audit spam).
- Failed-login limiter (5/60s, keyed per-IP, per-IP+email, and per-email so IP
rotation can't brute one account) since direct login bypasses the controller
throttler. Only real credential failures count.
- MCP_TOKEN shared guard moved off Authorization to an X-MCP-Token header
(timing-safe compare); credsConfigured 503 gate replaced by a clear 401.
- No secrets logged; all auth resolved before res.hijack() so failures return
clean 401 JSON. .env.example marks the service account optional.
Implements docs/backlog/mcp-per-user-auth.md (variant L).

The bulk embedding reindex could hang on a single page forever
("Indexed 27 of 34 pages") with zero log output:
- all progress logs were debug-level, suppressed in production (pino info);
- embedMany() had no timeout, so a slow/hung embeddings endpoint blocked
the sequential per-page loop indefinitely.
Changes:
- ai.service.embedTexts: bound embedMany with AbortSignal.timeout
(configurable via AI_EMBEDDING_TIMEOUT_MS, default 120000ms); on timeout
throw a clear, greppable message, classified by both signal.aborted and
the error name (TimeoutError/AbortError/ResponseAborted) so a real
provider error racing the timer keeps its diagnostics.
- embedding-indexer.reindexWorkspace: promote lifecycle/progress logs to
info; log "[i/N] indexing page <id>" BEFORE the await so a hang names the
stuck page; warn on slow pages (>30s); add timing + final summary.
- .env.example: document AI_EMBEDDING_TIMEOUT_MS.
Replace the removed enterprise EE MCP (private apps/server/src/ee submodule,
license-gated /mcp route) with our docmost-mcp, vendored as an isolated ESM
workspace package and served by the server over HTTP — no enterprise license.
Backend:
- Add packages/mcp (@docmost/mcp): vendored docmost-mcp refactored into a
side-effect-free createDocmostMcpServer() factory (38 tools preserved),
stdio entry kept in stdio.ts, Streamable-HTTP session manager in http.ts.
- Add apps/server McpModule: @Post/@Get/@Delete('mcp') (served at /mcp via the
existing global-prefix exclude), @SkipTransform + reply.hijack to bridge raw
Fastify req/res into the SDK transport. The module dynamically imports the
ESM-only package from CommonJS via a Function-indirected import resolved with
require.resolve + file:// URL. Gated by the workspace ai.mcp toggle, a
service-account (MCP_DOCMOST_EMAIL/PASSWORD/API_URL) and optional MCP_TOKEN;
per-session idle eviction (MCP_SESSION_IDLE_MS).
- Drop the enterprise license check on mcpEnabled in workspace.service.
- Dockerfile: copy packages/mcp into the production image.
- .env.example: document MCP_DOCMOST_*, MCP_TOKEN, MCP_SESSION_IDLE_MS.
Frontend:
- Recreate the community "AI & MCP" workspace-settings panel (mcp-settings.tsx):
admin-only toggle on settings.ai.mcp with optimistic update, copyable
${APP_URL}/mcp URL; wired into workspace-settings page. Reuses existing i18n.
Fixes:
- Pin packages/mcp tiptap deps to 3.20.4 (matching the client) and inline
getStyleProperty, preventing a duplicate @tiptap/core@3.26.1 from leaking into
the client editor via pnpm shamefully-hoist (was breaking apps/client tsc).
