feat: MCP token space-level allowlists (#6, second checklist item) - #141
Conversation
Closes #6's remaining checklist item: "MCP: token scoping extends to space-level, not just individual Document/Collection IDs." - New access_tokens.allowed_space_ids column (JSON array, mirroring the existing per-Document/per-Collection allowlist columns) — migration 0004. - tokenAllowsParent (src/lib/mcp/tokens.ts) composes the Space grant with the existing per-ID allowlists: a target is authorized if it's directly allowlisted OR its own catalog Space is one of the token's allowedSpaceIds — resolved live against the record's current spaceId, not backfilled, so a Space grant automatically covers content created in that Space afterward. - Threaded through every tokenAllowsParent call site (permissions.ts's requireAccessibleParent — the central gate used by nearly every service function — plus documents.ts, collections.ts, search.ts, holds.ts, records.ts's page_link validation), each now resolving and passing the target's spaceId. - settings/tokens UI gains an "Allowed Spaces" fieldset alongside the existing Documents/Collections checkboxes. - resolveShardForParent/resolveParentWorkspaceContext (catalog.ts/ permissions.ts) now also return the target's spaceId — the mechanism the above relies on. DocumentMeta/CollectionMeta gain an optional spaceId field, populated by listCatalogDocuments/listCatalogCollections. Tests: unit coverage for the composed tokenAllowsParent logic (tokens.test.ts), a real-service-layer authorization suite (space-isolation.test.ts), and a Tier A test exercising a Space-scoped token over the real MCP transport (tier-a.test.ts, per CLAUDE.md's "write a Tier A test for anything permission-/grant-related"). Not in this PR (noted as follow-up): MCP-driven Space creation, and create_document/create_collection targeting a token's granted Space from MCP — both still land in the workspace default Space only.

📝 WalkthroughWalkthroughAdds Space allowlists to MCP tokens. It persists and validates Space grants, applies them to document and collection authorization, supports Space-aware placement and isolation, and adds settings, unit, service, and E2E coverage. ChangesSpace-scoped MCP token permissions
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The change adds Space-scoped token authorization, but token-based document and collection creation can currently target any existing Space without honoring the token’s allowlist, creating a direct permission bypass; separately, some default-Space content may be incorrectly denied. These are current-head authorization and correctness issues that should be resolved before merging. Sequence Diagram(s)sequenceDiagram

…bit) settings/tokens' create action took spaceIds directly from the request and persisted them onto the new token unchecked — a crafted request could grant a token access to a Space id that exists but isn't part of this workspace, since Space membership alone later authorizes access via tokenAllowsParent. Now validates every submitted id against listSpaces(workspaceId) first, failing with a clean 400 otherwise. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Confirmed — a real bug at the intersection of this PR's Space-grant composition and #140's uncataloged-content-belongs-to-defaultSpaceId classification, only visible once both merged. 🤖 Addressed by Claude Code |
Follow-up to #140/#141's merge: listDocuments/listCollections classify uncataloged (legacy/direct-Yjs) content as belonging to the workspace's defaultSpaceId, but their uncataloged-fallback loops called tokenAllowsParent without passing that spaceId — a token whose only grant was a Space-level allowlist for the default Space (no per-record grant) was therefore denied access to content that structurally belongs to that same Space. Both loops now pass defaultSpaceId explicitly, matching the classification listDocuments/listCollections already use elsewhere. Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>
