Phase 2 — agent MCP tools for the unified requests/inbox subsystem

This is Phase 2 of the approved RFC. Phase 1 (workspace-server data model + REST endpoints) shipped in molecule-core PR #2525. This PR adds the agent-facing MCP tools in molecule-mcp-server that call those endpoints, mirroring the approvals.ts house pattern (every tool takes workspace_id = the acting agent).

The 7 tools (`src/tools/requests.ts`) and the P1 endpoints they call

Tool	Endpoint
`create_request`	`POST /workspaces/{id}/requests`
`list_inbox`	`GET /workspaces/{id}/requests/inbox?status=`
`check_requests`	`GET /workspaces/{id}/requests?status=` (async pickup of responses to requests this agent RAISED)
`get_request`	`GET /workspaces/{id}/requests/{requestId}`
`respond_request`	`POST /workspaces/{id}/requests/{requestId}/respond` (+ `POST .../messages` when a `message` is supplied)
`add_request_message`	`POST /workspaces/{id}/requests/{requestId}/messages`
`cancel_request`	`POST /workspaces/{id}/requests/{requestId}/cancel`

respond_request sends responder_type=agent, responder_id=workspace_id; add_request_message sends author_type=agent, author_id=workspace_id.

Contract correction vs the brief

The brief listed the action verbs as bare /requests/{requestId}/... paths. In the real P1 router (workspace-server/internal/router/router.go) those bare paths are AdminAuth-gated (the canvas user). The agent-side verbs (get, respond, messages, cancel) are registered under the workspace-token-auth wsAuth group /workspaces/:id/requests/.... Since all these tools act as an agent (workspace token), they correctly route through the /workspaces/{workspace_id}/... prefix — including get_request, which therefore also takes workspace_id (for auth scope) in addition to request_id.

Registration

registerRequestTools(srv) is wired into BOTH server modes (default surface + management), exactly like registerIssueTools. Handlers are re-exported from src/index.ts.

Untouched

Existing approval tools (create_approval, decide_approval, …) are left fully intact against the old /approvals endpoints. The formal shim/deprecation is a later phase (P5).

Tests & count

New src/__tests__/requests.test.ts (10 tests, fetch-mock): create task + approval, inbox vs check_requests, get, respond (+ thread-message variant), add_request_message, cancel, and an HTTP-error passthrough.
Tool-count assertion bumped 89 → 96 (+7) with toContain entries for all 7 tools.

Verify

npm run build (tsc): clean.
npx jest: 11 suites passed, 293 passed / 1 skipped.

Add the agent-facing MCP tools for the unified requests/inbox subsystem
(RFC Phase 2). Phase 1 (workspace-server data model + REST endpoints) is
molecule-core PR #2525. These 7 tools call those endpoints via apiCall/
platformGet and mirror the approvals.ts house pattern (workspace_id = the
acting agent).

Tools (all in src/tools/requests.ts):
- create_request  POST /workspaces/{id}/requests
- list_inbox      GET  /workspaces/{id}/requests/inbox
- check_requests  GET  /workspaces/{id}/requests
- get_request     GET  /workspaces/{id}/requests/{requestId}
- respond_request POST /workspaces/{id}/requests/{requestId}/respond (+messages)
- add_request_message POST /workspaces/{id}/requests/{requestId}/messages
- cancel_request  POST /workspaces/{id}/requests/{requestId}/cancel

Registered in BOTH server modes (default + management), same as create_issue.
Existing approval tools untouched (shim/deprecate in P5). Tool count 89 -> 96.

qa APPROVE (5-axis, 1st genuine lane — author devops-engineer≠me; CR-A security via cb15acea = 2nd). Correctness: P2 — new requests.ts (+271) implements the unified agent MCP request tools (create_request/list_inbox/check_requests/respond_request/get_request/add_request_message/cancel_request) routing to the workspace-server /requests endpoints. Robustness/Tests: 41 zod input-validation schemas (strong input hygiene — every tool param validated) + a 188-line test asserting the endpoint routing + payloads. Security/AUTHZ (privileged-surface axis): the tools FORWARD to server-side /requests endpoints — the server is the authz authority, same boundary as the #57 approval shims. respond_request sends responder_type='agent', responder_id=p.workspace_id (the agent's OWN claimed identity); a client-supplied workspace_id/recipient_id is validated SERVER-SIDE against the authenticated token (an agent can't respond for a workspace its token isn't authorized for). No tool-layer forge/bypass — the tool has no authority, it just POSTs validated input. 0 dangerous patterns (zero eval/exec/child_process). Content-sec: clean (0 IPs/creds/coords). Performance: n/a. Readability: clear zod schemas. NON-BLOCKING server-side note (same as #57, pre-existing): confirm /requests + /respond validate the client workspace_id/recipient_id against the token, not trust them blindly — workspace-server concern, not introduced here. Gate green, mergeable. Approving — privileged tool surface forwards to server-validated endpoints with strong zod input validation; integrity is server-side-bounded.

Security 5-axis — APPROVE (head e688aa30ed). feat(requests): P2 — agent MCP tools for the unified requests/inbox (+484: src/tools/requests.ts + index + tests). 1st security lane; author devops-engineer != me.

Design (client) — sound: create_request/list_inbox/check_requests/get_request/respond_request/add_request_message/cancel_request, all typed via zod (kind/recipient_type/action are ENUMS, ids/title strings) and routed through the centralized auth'd API client (apiCall/platformGet) — no hardcoded/leaked creds, no SQL/shell injection (JSON body to the platform API; server validates). They hit the per-workspace wsAuth prefix /workspaces/{workspace_id}/requests/... (the canvas verbs are AdminAuth-gated, not reachable with a workspace token).
AUTHZ (the load-bearing note): these tools take workspace_id as the acting-workspace param and responder_id=workspace_id. The authorization that the acting workspace == the request's recipient/requester is enforced SERVER-SIDE — which is exactly the gap I flagged on core#2525 (RC 10416: Respond/AddMessage/Cancel don't bind the authenticated :id to the participant → self-approval/cross-respond). mcp#56 is the CLIENT for those same endpoints, so these tools make that gap directly reachable by an agent (e.g. respond_request{action:approved} on its own request) IF the server isn't fixed.
→ HARD merge-ordering flag: mcp#56 must NOT ship before core#2525's server-side participant-binding fix lands. They're a pair (MCP client + server handlers); #2525's RC naturally gates this. The client itself is correct — the enforcement belongs server-side — so APPROVE the client, but its safety is contingent on #2525.
Non-blocking: add a workspace_id/request_id format check in the tools as defense-in-depth (path-interpolated; stays on PLATFORM_URL host + server-validated, so low-risk, but belt-and-suspenders).
Tests: non-vacuous (assert exact path/method/body per tool; fetch-mocked).
Gate GREEN. APPROVE (client sound) — gated on core#2525's authz fix before merge. CR-B 2nd lane → 2-distinct.
