Must-fix:
- mcp.module: drop the now-dead EnvironmentModule import (and its stale
comment). McpService no longer injects EnvironmentService; EnvironmentModule
is @Global and imported at the app root, so DI still resolves.
Stability:
- environment.service: route getSandboxTtlMs + the three SANDBOX_MAX_*_BYTES
caps through a shared getPositiveIntEnv() helper that warns once per key and
falls back to the default on a non-integer or <= 0 value (previously the byte
caps did a bare parseInt, so SANDBOX_MAX_TOTAL_BYTES=0 made every stash_page
fail against a 0-byte cap). TTL behavior is unchanged.
Simplification:
- sandbox.controller: replace the homemade UUID_RE with the project's shared
`uuid` validator (import { validate as isValidUUID } from 'uuid'), matching
the attachment routes; update the spec fixtures to valid v4 UUIDs.
- mcp.service: inline the single-caller one-liner buildSandboxConfig() to
this.sandboxStore.asSink() at the wiring site.
Docs:
- CHANGELOG: add an [Unreleased] > Added entry for #243 (stash_page tool,
anonymous GET /api/sb/:id, five SANDBOX_* env vars).
- AGENTS.md: note that GET /api/sb/:id is in the workspace-gate preHandler's
excludedPaths and is fully tokenless, unlike /api/files/public/... which
still resolves a workspace and needs an attachment JWT.
Tests: cap-getter validation (0/-5/abc -> default, valid -> parsed), updated
UUID fixtures. apps/server jest sandbox/environment/mcp: 233 pass.

Security (must-fix):
- sandbox.controller: the anonymous GET /api/sb/:id response now sets
X-Content-Type-Options: nosniff, a restrictive CSP, and Content-Disposition=
attachment for any mime outside a raster-image allowlist (png/jpeg/gif/webp/
avif). entry.mime is attacker-controlled, so an evil.svg/evil.html could
otherwise execute script inline on the Docmost origin (stored XSS). Mirrors
the public attachment route's hardening.
Stability:
- client.stashPage: reconcile mirrors AFTER the final document put, not only
before it. The doc blob is the newest entry and FIFO eviction drops the
oldest = this stash's own images, so the stored doc could reference an
evicted blob (consumer 404) and over-report images.mirrored. A bounded loop
now reverts doc-put-evicted mirrors, drops the stale doc blob, and re-puts
until stable. Regenerated packages/mcp/build/.
- sandbox.controller: emit Cache-Control on the 304 branch too (ttlSeconds is
computed before the conditional check).
Docs:
- Bump the MCP tool count 39 -> 40 across all READMEs and AGENTS.md (the
registry now exposes exactly 40 tools).
Refactor:
- SandboxStore.asSink() centralizes the {put,has,evict} sink + uri<->id
mapping; the embedded-MCP and in-app agent-tools wiring sites share it.
Tests:
- security headers (inline vs attachment, nosniff, CSP), 304 Cache-Control,
putAndLink URL form, has()/remove(), asSink() round-trip, getSandboxPublicUrl
(trailing-slash trim + APP_URL fallback), and a stash test where the doc put
itself evicts a mirrored image.

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.

1. gitRemote is NOT yet consumed (the vendored engine has no remote-push path,
SPEC §7). Corrected the buildSettings docstring (it wrongly called gitRemote
"load-bearing") and marked the env -> validation -> getter -> buildSettings
chain as inert SCAFFOLDING for the deferred remote-push feature at all three
sites. Kept the wiring (harmless; removing only churns).
2. .env.example: document that GIT_SYNC_REMOTE_TEMPLATE substitutes the literal
"{spaceId}" per-space (with the example), so an operator doesn't point every
space at one remote.
3. Extracted the copy-pasted CJS->ESM dynamic-import bridge
(`new Function('s','return import(s)')`) into one shared
common/helpers/esm-import.ts; git-sync.loader, docmost-client.loader and
mcp.service now import it and keep their own typed loadX() wrappers.
Deferred (notes only, not implemented):
- lcs.ts + three-way-merge.ts could move into packages/git-sync, but that engine
is vendored (manual re-sync) — added a one-line note at three-way-merge.ts to
revisit once the re-sync story is settled.
- schema-core single source + BullMQ/fencing remain documented from prior rounds.

isBlocked was checked synchronously but recordFailure ran only AFTER the bcrypt
awaits, so N concurrent /mcp Basic requests for one email all slipped past the
threshold. Add FailedLoginLimiter.tryReserve (atomic synchronous check+increment)
+ release (undo), and reserve all 3 keys BEFORE any await so the (threshold+1)-th
concurrent attempt is rejected before its bcrypt runs. The reservation IS the
failure record (post-await recordFailure removed -> counted exactly once). Non-
credential early throws (missing workspace, SSO/MFA gate) and business errors
release the reservation so they don't burn a victim's budget; success clears.
Tests prove login() runs exactly threshold times under concurrency and that
gate/config rejects don't consume budget.

McpService.enforceBasicLoginGate re-implements AuthController.login's pre-token
SSO/MFA gate; silent drift would re-open the bypass. Add an AST contract test
(comments stripped) asserting BOTH method bodies contain validateSsoEnforcement,
the EE-MFA require, and checkMfaRequirements — so dropping the gate from either
side fails CI. Test-only (no core/auth refactor).

The shared MCP_TOKEN guard moved from 'Authorization: Bearer <MCP_TOKEN>' to the
X-MCP-Token header (Authorization is now per-user Basic/Bearer), silently breaking
existing /mcp clients. Document it as a Breaking Change in CHANGELOG (reconfigure
to X-MCP-Token). Add a once-per-process migration warning: when MCP_TOKEN is set,
no x-mcp-token is present, and Authorization carries the old 'Bearer <MCP_TOKEN>',
log a hint to migrate — without changing the auth decision (still rejected) or
logging the token value.

After develop merged, mcp.service.ts calls decideBasicGate from mcp-auth.helpers.
The gate spec mocked the whole module returning only FailedLoginLimiter, so the
merged code crashed with 'decideBasicGate is not a function' (7/7 failing).
Spread jest.requireActual('./mcp-auth.helpers') so the real helpers are kept and
the gate exercises real logic; keep only FailedLoginLimiter stubbed so its
constructor runs without a real sweep timer.

Add ~330 tests across server (Jest), client (Vitest), editor-ext (Vitest)
and packages/mcp (node:test) for the gitmost features added since
053a9c0d: AI chat, AI agent roles, public-share assistant, MCP per-user
auth, HTML embed, page templates/embed, realtime tree, tree
expand/collapse, and the AI-settings UI.
Test-tooling fixes (prerequisite, were silently hiding coverage):
- Repair 3 page-template specs broken by the 11-arg TransclusionService
constructor; they never compiled, so template access-control / content
-leak / unsync-strip coverage was fictitious.
- Build @docmost/editor-ext before server tests via a `pretest` hook;
the stale dist omitted the new HtmlEmbed/PageEmbed exports (TS2305).
- Let jest resolve the .tsx email templates: add `tsx` to
moduleFileExtensions and widen the ts-jest transform to (t|j)sx?.
Behaviour-preserving "extract pure core" refactors that the tests drive:
- server: resolveShareAssistantRequest + uiMessageTextLength
(public-share controller), decideBasicGate + mapAuthResultToResponse
(mcp), buildErrorAssistantRecord (ai-chat), jsonbObject export (roles).
- client: render-raw-html + shouldExecute/canEdit, decide-embed-state,
page-embed picker utils, tree-socket reducers, open/close branch maps,
isEndpointConfigured/resolveKeyField; buildTreeWithChildren now treats
a permission-trimmed orphan as a root instead of crashing.
Deferred (need a test DB or HTTP harness, documented in the specs):
repo-level Postgres integration tests and the public-share XFF E2E.
Pre-existing DI/lib0-ESM suite failures are untouched and out of scope.

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.

Release-cycle test audit: the /mcp auth's constant-time token guard, IP keying,
ACCESS-type pinning, and brute-force message coupling were untested. Extract
behavior-preserving pure helpers so they're testable and cover them:
- sharedTokenMatches: length-mismatch early-returns before timingSafeEqual
(which throws on unequal lengths); equal-length uses timingSafeEqual; array
header -> first element; non-string -> false.
- clientIp: req.ip > socket > first XFF hop > 'unknown' (limiter keying).
- bindAccessJwtVerifier: verifyJwt pinned to JwtType.ACCESS (rejects REFRESH).
- CREDENTIALS_MISMATCH_MESSAGE single source of truth shared by
verifyUserCredentials and isCredentialsFailure, so a reworded auth error can't
silently disable the /mcp brute-force counter.
- verifyUserCredentials no-side-effect contract asserted via a TS-AST spec
(AuthService can't load under jest): its body has no createSessionAndToken/
audit/updateLastLogin while login() has all three.
Extractions are behavior-preserving (reviewed); class delegates to the helpers,
dead code + unused imports removed.

Release-cycle review found the /mcp Basic path skipped the controller's
pre-token gates and over-eagerly minted sessions:
- SSO/MFA bypass (blocker): the Basic path called AuthService.login/
verifyUserCredentials directly, but validateSsoEnforcement + the lazy EE MFA
gate live in AuthController.login. Now enforceBasicLoginGate runs in the Basic
branch BEFORE any token is minted: validateSsoEnforcement(workspace) (reject
on enforced SSO) and the same lazy-require MFA check the controller uses
(reject MFA users -> 'use a Bearer access token'). No EE module bundled (this
fork) -> no MFA gate, identical to the controller; a throw from the check
fails closed (no token). Bearer/service-account paths are not gated (those
JWTs are minted post-gate).
- Non-init session mint: isSessionInit is now (no mcp-session-id) AND the body
is a real JSON-RPC initialize (isInitializeRequestBody). A header-less
non-initialize request takes the side-effect-free verifyCredentials path -> no
user_sessions row, no USER_LOGIN audit, no lastLoginAt bump.
- FailedLoginLimiter.sweep() now runs on an unref'd 60s interval, cleared on
module destroy (was never scheduled -> unbounded Map growth under XFF rotation).
- Subsequent (non-init) valid login no longer resets the global per-email brute
bucket (only per-IP / per-IP+email); the email backstop is reset only on a
deliberate init login.
Note: in a hypothetical EE build, checkMfaRequirements is called with no
FastifyReply (we only read requirement flags); a res-dereferencing EE impl would
surface as a clean rejection (fail-closed), not a bypass.

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).

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).
