From 1dcfdc8b056002aed43eaf89098328df7f056cef Mon Sep 17 00:00:00 2001 From: Michal Date: Tue, 28 Apr 2026 15:06:31 +0100 Subject: [PATCH] feat(mcpd): async inference task API + tasks RBAC resource (v5 Stage 3) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Exposes the durable queue (Stage 1+2) as a first-class API so callers can enqueue work, get a task id immediately, and poll/stream/cancel without holding open the original HTTP connection. New endpoints (`/api/v1/inference-tasks`): POST / → enqueue, return task id (201 + row). failFast:false — task stays pending if no worker is up; future bindSession drains. Rejects 400 for public Llms (the existing /llms//infer is the right tool there) and 404 for missing Llms. GET / → list owner's tasks. Optional ?status, ?poolName, ?agentId, ?limit query. Owner-scoped at the route layer; cross- user listing requires resource-wide grant. GET /:id → poll one task. 404 (not 403) on a foreign-owner id to prevent enumeration. DELETE /:id → cancel a non-terminal task. Already- terminal rows return 200 + current shape (no-op). 404 on foreign owner. GET /:id/stream → SSE feed of `chunk` and `terminal` events. Re-fetches the row at subscribe time so already-completed tasks emit one terminal event and close immediately. RBAC: - New `tasks` resource added to RBAC_RESOURCES + the URL→permission map in main.ts. Default action mapping: GET=view, POST=create, DELETE=delete. The route layer enforces owner-scoping ON TOP of the hook (404 on foreign owner) — without this, anyone with `view:tasks` could list/peek every user's queued work. - Singular alias `task` and the multi-word `inference-task` / `inference-tasks` all normalize to `tasks` so users can write `mcpctl create rbac-binding --resource task --role view ...` or any of the variants and have it map correctly. Tests: 9 new route tests covering the wire shapes, owner scoping (matching/foreign), public-Llm rejection, missing-Llm 404, list filter, and cancel semantics (pending→cancelled, terminal→no-op). mcpd 893/893 (was 884, +9). Live smoke: POST against a public Llm returns the documented 400, POST against missing returns 404, GET list returns [] cleanly. Stage 4 (next): CLI surface (`mcpctl get tasks`, `--async` flag on chat-llm), GC ticker, smoke test (enqueue → connect worker → drain), docs. --- src/mcpd/src/main.ts | 11 + src/mcpd/src/routes/inference-tasks.ts | 281 ++++++++++++++++++ .../src/validation/rbac-definition.schema.ts | 9 +- src/mcpd/tests/inference-task-routes.test.ts | 268 +++++++++++++++++ 4 files changed, 568 insertions(+), 1 deletion(-) create mode 100644 src/mcpd/src/routes/inference-tasks.ts create mode 100644 src/mcpd/tests/inference-task-routes.test.ts diff --git a/src/mcpd/src/main.ts b/src/mcpd/src/main.ts index 4375cfa..f2b0daf 100644 --- a/src/mcpd/src/main.ts +++ b/src/mcpd/src/main.ts @@ -43,6 +43,7 @@ import { LlmAdapterRegistry } from './services/llm/dispatcher.js'; import { registerLlmRoutes } from './routes/llms.js'; import { registerLlmInferRoutes } from './routes/llm-infer.js'; import { registerVirtualLlmRoutes } from './routes/virtual-llms.js'; +import { registerInferenceTaskRoutes } from './routes/inference-tasks.js'; import { VirtualLlmService } from './services/virtual-llm.service.js'; import { registerAgentRoutes } from './routes/agents.js'; import { registerAgentChatRoutes } from './routes/agent-chat.js'; @@ -169,6 +170,11 @@ function mapUrlToPermission(method: string, url: string): PermissionCheck { 'promptrequests': 'promptrequests', 'mcptokens': 'mcptokens', 'llms': 'llms', + // v5: durable inference task queue.
