From 3726a65f535ce170f95ed68070e0fa8bf8d23cba Mon Sep 17 00:00:00 2001 From: Michal Date: Sat, 25 Apr 2026 16:29:55 +0100 Subject: [PATCH 01/14] feat(agents): add Agent + ChatThread + ChatMessage schema (Stage 1) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduces the persistence layer for the upcoming Agent feature: an LLM persona pinned to a specific Llm, optionally attached to a Project, with persisted chat threads/messages so conversations survive REPL exits. Constraint shape: - Agent.llm uses ON DELETE RESTRICT — deleting an Llm in active use fails. - Agent.project uses ON DELETE SET NULL — agents survive project deletion. - ChatThread → ChatMessage cascade so deleting an agent purges its history. - ChatMessage @@unique([threadId, turnIndex]) gives append ordering even under racing writers (services retry on collision). LiteLLM-style per-call overrides will live in Agent.defaultParams (Json); the loose extras Json field is reserved for future LoRA/tool-allowlist work. Pinned vitest fileParallelism=false in @mcpctl/db: all suites share the same Postgres, and adding a second suite exposed FK contention between a clearAllTables in one file and a create in another. Per-test isolation still comes from beforeEach. Tests: 8/8 green in src/db/tests/agent-schema.test.ts (defaults, name uniqueness, llm-in-use Restrict, project-delete SetNull, agent-delete cascade, duplicate (threadId, turnIndex) blocked, tool-call payload round-trip, lastTurnAt DESC ordering).

AgentService mirrors LlmService's CRUD shape with name-resolved llm/project references and yaml round-trip support; ChatService is the orchestrator that drives one chat turn end-to-end: build the merged system block (agent.systemPrompt + project Prompts ordered by priority desc + per-call systemAppend), persist the user turn, run the adapter, dispatch any tool_calls through an injected ChatToolDispatcher, persist tool turns linked back via toolCallId, and loop until the model returns terminal text. Per-call params resolve LiteLLM-style: request body → agent.defaultParams → adapter default. The escape hatch `extra` is forwarded as-is so each adapter can cherry-pick provider-specific knobs (Anthropic metadata, vLLM repetition_penalty, etc.) without code changes here. Persistence is non-transactional across the loop because tool calls can take minutes; long-held DB transactions would starve other writers. Instead each in-flight assistant turn is written `pending` and flipped to `complete` only after its tool results land. On failure or max-iter overrun, every `pending` row in the thread is flipped to `error` so the trail is auditable. Tools are namespaced on the wire as `__`, unmarshalled at dispatch time; `tools_allowlist` filters before the model sees the list. Tests: agent-service.test.ts (7) — CRUD with name-resolved llm/project, conflict on duplicate, llm switch, project detach, listByProject filtering, upsertByName branch coverage. chat-service.test.ts (9) — plain text turn, full text→tool→text loop with toolCallId linkage, max-iter cap leaves zero pending, adapter-throws leaves zero pending, body→defaultParams merge, `extra` passthrough, project-Prompt priority ordering in the system block, tool-without- project rejection, tools_allowlist filtering. All 16 green; full mcpd suite still 737/737.

charset=UTF-8 Content-Transfer-Encoding: 8bit Wires the Stage 2 services into HTTP. New routes: GET /api/v1/agents — list GET /api/v1/agents/:idOrName — describe POST /api/v1/agents — create PUT /api/v1/agents/:idOrName — update DELETE /api/v1/agents/:idOrName — delete GET /api/v1/projects/:p/agents — project-scoped list (mcplocal disco) POST /api/v1/agents/:name/chat — chat (non-streaming or SSE stream) POST /api/v1/agents/:name/threads — create thread explicitly GET /api/v1/agents/:name/threads — list threads GET /api/v1/threads/:id/messages — replay history The chat endpoint reuses the SSE pattern from llm-infer.ts (same headers incl. X-Accel-Buffering:no, same `data: …\n\n` framing, same `[DONE]` terminator). Each ChatService chunk is one frame. Non-streaming returns {threadId, assistant, turnIndex} as JSON. RBAC mapping in main.ts:mapUrlToPermission: - /agents/:name/{chat,threads*} → run:agents: - /threads/:id/* → view:agents (service-level owner check handles fine-grained access since the URL doesn't carry the agent name) - /agents and /agents/:idOrName → default {GET:view, POST:create, PUT:edit, DELETE:delete} on resource 'agents'. 'agents' added to nameResolvers so RBAC's CUID→name lookup works. ChatToolDispatcherImpl bridges ChatService to McpProxyService: it lists a project's MCP servers, fans out tools/list calls to each, namespaces tool names as `__`, and routes tools/call back to the right serverId on dispatch. tools/list errors on a single server are logged and that server's tools are dropped from the turn's tool surface — one bad server doesn't poison the whole list. Tests: agent-routes.test.ts (15) — full HTTP CRUD round-trip, 404/409 paths, project-scoped list, non-streaming + SSE chat, thread create/list, /threads/:id/messages replay, body-required 400. chat-tool-dispatcher.test.ts (7) — empty list when no project / no servers, namespacing + inputSchema forwarding, partial-failure skipping with audit log, callTool dispatch shape, missing-server rejection, JSON-RPC error surfacing. All 22 new green; mcpd suite now 759/759 (was 737).

charset=UTF-8 Content-Transfer-Encoding: 8bit When a Claude (or any other MCP client) connects to a project's mcplocal endpoint, every Agent attached to that project now appears in the session's tools/list as a virtual MCP server named `agent-` with one tool `chat`. Calling that tool POSTs to the Stage 3 chat endpoint and returns the assistant's reply as MCP content. The tool's description is the agent's own description, so connecting clients see prose like "I review security design — ask me after each major change." This is what makes one agent reachable from another's MCP session. Plumbing: * src/mcplocal/src/proxymodel/plugins/agents.ts (new) — the plugin. onSessionCreate fetches /api/v1/projects/:p/agents via mcpd, then registers a VirtualServer per agent. The chat tool's inputSchema mirrors the LiteLLM-style override surface (temperature, top_p, top_k, max_tokens, stop, seed, tools_allowlist, extra) plus threadId for follow-ups. Namespace collision with an existing upstream MCP server named `agent-` is detected and skipped with a `ctx.log.warn` line — better to surface the conflict than to silently shadow real tool entries in the virtualTools map. * src/mcplocal/src/proxymodel/plugins/compose.ts (new) — generic N-plugin composition helper. Lifecycle hooks fan out in order; transform hooks (onToolsList, onResourcesList, onPromptsList, onToolCallAfter) pipeline; intercept hooks (onToolCallBefore, onResourceRead, onPromptGet, onInitialize) short-circuit on the first non-null. Generalizes what createDefaultPlugin does for two fixed parents. * src/mcplocal/src/http/project-mcp-endpoint.ts — every project session now uses composePlugins([defaultPlugin, agentsPlugin]) so agents show up no matter which proxymodel the project is on. * Plugin context: added getFromMcpd(path) alongside postToMcpd. The existing postToMcpd was hard-coded to POST; the agents plugin needs GET to discover. Wired through plugin.ts → plugin-context.ts → router.ts. Tests: plugin-agents.test.ts (8) — registers per agent, falls back to a generic description, skips on namespace collision, no-ops with zero agents, logs and continues on mcpd error, chat handler POSTs correct body and returns content array, isError surfacing on mcpd error, onSessionDestroy unregisters everything. plugin-compose.test.ts (6) — single-plugin pass-through, empty rejection, lifecycle ordering, intercept short-circuit, list pipeline, no-op composition stays minimal. mcplocal suite: 715/715. mcpd suite still 759/759.

charset=UTF-8 Content-Transfer-Encoding: 8bit This is the moment the user can actually talk to an agent end-to-end: mcpctl create llm qwen3-thinking --type openai --model qwen3-thinking \ --url http://litellm.nvidia-nim.svc.cluster.local:4000/v1 \ --api-key-ref litellm-key/API_KEY mcpctl create agent reviewer --llm qwen3-thinking --project mcpctl-dev \ --description "I review security design — ask me after each major change." mcpctl chat reviewer Pieces: * src/cli/src/commands/chat.ts (new) — REPL + one-shot. Streams the SSE endpoint and prints text deltas to stdout as they arrive; tool_call / tool_result events go to stderr in dim-style brackets so the chat output stays clean. LiteLLM-style flags (--temperature / --top-p / --top-k / --max-tokens / --seed / --stop / --allow-tool / --extra) layer over agent.defaultParams. In-REPL slash-commands: /set KEY VAL, /system , /tools (list project's MCP servers), /clear (new thread), /save (PATCH agent.defaultParams = current overrides), /quit. * src/cli/src/commands/create.ts — `create agent` mirroring the llm pattern. Every yaml-applyable field has a corresponding flag (memory rule); --default-temperature / --default-top-p / --default-top-k / --default-max-tokens / --default-seed / --default-stop / --default-extra / --default-params-file all populate agent.defaultParams. * src/cli/src/commands/apply.ts — AgentSpecSchema accepts both `llm: qwen3-thinking` shorthand and `llm: { name: ... }` long form; runs after llms in the apply order so apiKey/llm references resolve. Round- trips with `get agent foo -o yaml | apply -f -` (memory rule). * src/cli/src/commands/get.ts — agentColumns (NAME, LLM, PROJECT, DESCRIPTION, ID); RESOURCE_KIND mapping for yaml export. * src/cli/src/commands/shared.ts — `agent`/`agents`/`thread`/`threads` added to RESOURCE_ALIASES. * src/cli/src/index.ts — wires createChatCommand into the program; passes the resolved baseUrl + token so chat can stream SSE without going through ApiClient (which only does buffered request/response). * completions/mcpctl.{fish,bash} regenerated. scripts/generate-completions.ts knows about agents (canonical + aliases) and emits a special-case `chat)` block that completes the first arg with `mcpctl get agents` names. tests/completions.test.ts: +9 new assertions covering agents in the resource list, chat in the commands list, --llm flag for create agent, agent-name completion for chat, etc. CLI suite: 430/430 (was 421). Completions --check is clean.

Smoke tests (run via `pnpm test:smoke` against a live mcpd at $MCPD_URL, default https://mcpctl.ad.itaz.eu): * tests/smoke/agent.smoke.test.ts — full CRUD round-trip: create secret + Llm + agent with sampling defaults; `get agents` surfaces it; `get agent foo -o yaml | apply -f` round-trips identically; create + list a thread via the HTTP API; agent delete leaves Llm + secret intact (Restrict + SetNull as designed). Self- skips with a warning when /healthz is unreachable. * tests/smoke/agent-chat.smoke.test.ts — gated on MCPCTL_SMOKE_LLM_URL + MCPCTL_SMOKE_LLM_KEY. Provisions secret + Llm + agent against a real upstream, runs `mcpctl chat -m … --no- stream` (asserts a reply lands), then runs the streaming default (asserts text on stdout + `(thread: …)` on stderr). The fast path for verifying the in-cluster qwen3-thinking deployment: MCPCTL_SMOKE_LLM_URL=http://litellm.nvidia-nim.svc.cluster.local:4000/v1 \ MCPCTL_SMOKE_LLM_MODEL=qwen3-thinking \ MCPCTL_SMOKE_LLM_KEY=$(pulumi config get --stack homelab \ secrets:litellmMcpctlGatewayToken) \ pnpm test:smoke Docs: * README.md — new "Agents" section under Resources with the qwen3-thinking quickstart and links to docs/agents.md and docs/chat.md. Adds llm + agent rows to the resources table. * docs/agents.md (new) — full reference: data model, chat-parameter table, HTTP API, RBAC mapping, tool-use loop semantics, yaml round-trip shorthand, the kubernetes-deployment wiring recipe, and a troubleshooting section (namespace collision, llm-in-use, pending-row recovery, Anthropic-tool limitation). * docs/chat.md (new) — user-facing `mcpctl chat` walkthrough: modes, per-call flags, slash-commands, threads, and a troubleshooting section. * CLAUDE.md — adds a "Resource types" cheatsheet with one-line pointers to each, including the new `agent` row that links to the docs. All suites still green: mcpd 759/759, mcplocal 715/715, cli 430/430. Smoke tests typecheck and self-skip when no live mcpd is reachable.

Adds a `healthCheck(backendId)` method that runs lookup-self without minting — so the boot-time loop can detect the dead-token state immediately, not 24 hours later. secret-backend-rotator-loop.ts Boot-time health check: in `start()`, for every rotatable backend, call `rotator.healthCheck(b.id)` and on failure log a structured fatal entry. This converts the prior silent failure mode (24h wait until scheduled rotation reveals the dead token, with secret writes failing under it the entire time) into "mcpd boots, immediately sees the dead token, alerts loudly". Existing isOverdue path is unchanged. mcpd — Prisma userId crash on /me ================================= routes/auth.ts GET /api/v1/auth/me used `request.userId!` which lied: an authenticated McpToken bearer satisfies the auth middleware but has no associated User row, so userId stayed undefined and `findUnique({ id: undefined })` threw PrismaClientValidationError. Now returns 401 with a clear "service-account/token-bound principal cannot be queried via /me" message instead of bubbling a 500. mcplocal — token revocation propagation ======================================= http/token-auth.ts Lowered default introspection positiveTtl from 30s → 5s. mcpd's introspection endpoint is a single DB lookup; the cache only protects against burst restart storms, not steady-state load. The 30s window let revoked tokens keep working for the full window after revocation (caught by mcptoken.smoke's negative-cache assertion). Aligns with the existing 5s negativeTtl and the test's `wait 7s after revoke` expectation. smoke tests — read URL the same way the CLI does ================================================ mcp-client.ts Adds `loadMcpdAuth()`: URL from `~/.mcpctl/config.json`, token from `~/.mcpctl/credentials`. Critically, the URL does NOT come from credentials. credentials.mcpdUrl carries a stale field for legacy reasons and goes out of sync (left over from old `mcpctl login --mcpd-url localhost:3xxx` invocations) — tests reading it ended up hitting whatever URL the user last logged into rather than the URL the CLI is actually using right now. audit/security/system-prompts smoke now use loadMcpdAuth(), eliminating ~10 cascade failures. Also: switch httpRequest to https.request when scheme is https (matching audit/security/system-prompts/mcp-client/agent helpers). Bumps default callTool timeout from 30s → 60s; many tools that fetch external resources routinely run 10-30s. agent.smoke.test.ts - readToken read from `credentials.json`; the file is `credentials` (no extension). Caused 401 on POST /threads. - `mcpctl get -o json` returns an array, not a bare object. Round-trip yaml test now indexes [0] before reading description. secretbackend.smoke.test.ts Two genuine assertion-drift fixes (env was right, test was stale): - "lists at least one secretbackend": stop hard-coding the default backend type as 'plaintext'; the invariant is "exactly one default exists". The seeded plaintext is the bootstrap default but operators routinely promote a remote backend (openbao etc.) once it's healthy. - "refuses to delete the seeded default": widen the regex from /default|in use|cannot delete/ to also accept "referenced" — the exact wording has shifted to "is still referenced by N secret(s); migrate them first". audit.test.ts / system-prompts.test.ts / security.test.ts Switch http.request → https.request when URL is https (each had its own copy of the helper). Drop the now-orphan loadMcpdCredentials in favour of loadMcpdAuth from mcp-client.ts. Tests ===== mcpd 759/759, mcplocal 715/715 unit suites still green. Smoke (live): Run 1 (pre-commit, post bao-token rotation): 27 → 12 failures. Run 2 (after fixes-batch, pre-redeploy): 12 → 2 failures. The remaining 2 (mcptoken cache TTL, proxy-pipeline timeout) are what the durable code changes here address; verify after the next redeploy.

The middleware default in token-auth.ts is 5s, but serve.ts wraps the construction with its own env-fallback default of 30000ms — so when MCPLOCAL_TOKEN_POSITIVE_TTL_MS isn't set in the environment, serve.ts always wins and revoked tokens still propagate slowly.

Any caller with view:agents could read another user's thread by guessing/learning the threadId. CUIDs are hard to brute-force but they leak: SSE `final` chunks, agents-plugin `_meta.threadId`, and several response bodies surface them. Now ChatService.listMessages(threadId, ownerId) loads the thread, returns 404 (not 403, to avoid id-enumeration via differential status codes) if ownerId doesn't match. Regression test in chat-service.test.ts covers Alice/Bob isolation + nonexistent-thread same-shape 404. P2 — AgentChatRequestSchema strict mode ======================================== validation/agent.schema.ts `.merge()` does NOT inherit `.strict()` from AgentChatParamsSchema. Typo'd fields (e.g. `temprature`) silently fell through and the agent silently used the default — debuggable only by reading the LLM call payload. Re-applied `.strict()` on the merged schema. P2 — per-agent maxIterations override + clamp ============================================== chat.service.ts Loop cap was a hard-coded module constant (12), wrong for both research-style agents (need higher) and cheap-probe agents (could opt lower). Now reads `agent.extras.maxIterations`, clamps 1..50, falls back to 12 default. The clamp is the soft-DoS guard: a hostile agent definition with `maxIterations:1000000` can't burn unbounded LLM calls per request. Both chat() and chatStream() use ctx.maxIterations now. Regression test covers low-cap override (rejects with `exceeded 2`) and hostile-value clamp (rejects with `exceeded 50`). P3 — SSE write to closed socket ================================ routes/agent-chat.ts When the upstream adapter throws after some chunks were already written AND the client disconnected, the catch block tried to flush more chunks to a closed socket. Without an `on('error')` handler Node emits unhandled error events; once Pino is wired to alerts this'd page on every disconnect-mid-stream. writeSseChunk now checks `reply.raw.destroyed || writableEnded` before write. P3 — BACKEND_TOKEN_DEAD preserves original stack ================================================= services/secret-backend-rotator.service.ts When wrapping mintRoleToken/lookupSelf failures as BACKEND_TOKEN_DEAD, the new Error() discarded the original throw — hard to tell whether the inner failure was a network blip vs an OpenBao API mismatch vs DNS. Now uses `new Error(msg, { cause: err })` so the inner stack survives.

Catches misconfigured tokens / wrong URLs at registration with a 422 + structured error message, instead of silently 500-ing on first chat with a generic "fetch failed". Caught in the wild today: the homelab Pulumi config exposed `MCPCTL_GATEWAY_TOKEN` (which is mcpctl_pat_-prefixed, intended for LiteLLM→mcplocal direction) where LiteLLM expects `LITELLM_MASTER_KEY` (sk-prefixed). The probe makes this immediate. Probe shape (LlmAdapter.verifyAuth): - OpenAI passthrough → GET /v1/models. Cheap, idempotent, gated by the same auth as chat/completions. - Anthropic → POST /v1/messages with max_tokens:1, "ping". Anthropic has no list-models endpoint; this is the cheapest auth-exercising call. - Returns one of: { ok: true } { ok: false, reason: "auth", status, body } — 401/403, fail hard { ok: false, reason: "unreachable", error } — network, warn-only { ok: false, reason: "unexpected", status, body } — non-auth 4xx, warn-only Behavior: - LlmService.create()/update() runs the probe after resolveApiKey. Throws LlmAuthVerificationError on `auth`, logs warn for unreachable/unexpected, swallows for offline registration. - Probe is skipped when there's no apiKeyRef (nothing to verify) or when the caller passes skipAuthCheck=true. - update() probes only when apiKeyRef OR url changes — pure description/tier updates don't trigger upstream calls. - Routes catch LlmAuthVerificationError and return 422 with `{ error, status }`. The CLI surfaces the message verbatim via ApiError. Opt-out: - CLI: `mcpctl create llm ... --skip-auth-check` for offline registration before the upstream is reachable. - HTTP: side-channel body field `_skipAuthCheck: true` (stripped before validation, never persisted on the row). Side fix in same commit (caught while testing): src/cli/src/index.ts read `program.opts()` BEFORE `program.parse()`, so `--direct` was a no-op for ApiClient — every command went to mcplocal regardless. Some commands accidentally still worked because mcplocal forwards plain `/api/v1/*` to mcpd, but flows that need direct SSE streaming (e.g. `mcpctl chat`) couldn't reach mcpd. Fixed by peeking at process.argv directly for the two global flags before Commander's parse runs. Tests: - llm-adapters.test.ts (+8): OpenAI 200/401/403/404/network, Anthropic 200/401/400 (typo'd model = unexpected, NOT auth — registration shouldn't block on bad model names that surface at chat time). - llm-service.test.ts (+6): create-throws-on-auth-fail (no row written), warn-only on unreachable/unexpected, skipAuthCheck bypass, no-key skip, update-only-probes-on-auth-affecting-change. mcpd 775/775, mcplocal 715/715, cli 430/430.

fix --no-stream timeout MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reasoning models (qwen3-thinking, deepseek-reasoner, OpenAI o1 family) emit their scratchpad as `delta.reasoning_content` (or `delta.reasoning`, or `delta.provider_specific_fields.reasoning_content` when LiteLLM passes through from vLLM) — separate from `delta.content`. Before this commit mcpd's parseStreamingChunk only watched `content`, so the model's 30-90s reasoning phase looked like dead air to the REPL: streaming connection open, no chunks, no progress. Caught during the agents-feature shakedown when qwen3-thinking sat silent for 90s on a docmost__list_pages call. mcpd ==== chat.service.ts - parseStreamingChunk extracts a `reasoningDelta` from the chunk body, accepting all four spellings (reasoning_content / reasoning / provider_specific_fields.{reasoning_content,reasoning}). Future providers can add their own field names by extending the fallback chain. - chatStream yields `{ type: 'thinking', delta }` chunks as reasoning arrives, alongside the existing `{ type: 'text', delta }` for content. - Reasoning is intentionally NOT persisted to the thread. It's the model's scratchpad, not part of the conversation. Subsequent turns don't see it. - Adds 'thinking' to the ChatStreamChunk.type union. CLI === chat.ts - streamOnce handles 'thinking' chunks: writes them dim+italic to stderr (ANSI 2;3m) so the model's reasoning visually flows like a quote block while the final answer streams to stdout. Plain text when stderr isn't a TTY (pipe to file → no escape codes leak). - chatRequestNonStream replaces the shared ApiClient.post() for the --no-stream path. ApiClient defaults to a 10s timeout, way too tight for any chat that calls a tool: LLM round + tool dispatch + LLM summary easily exceeds 10s. The new helper uses the same 600s timeout the streaming path has been using all along. Tests: chat-service.test.ts (+2): - reasoning_content deltas surface as `thinking` chunks (not text); reasoning is NOT persisted to the assistant turn's content. - LiteLLM's provider_specific_fields.reasoning_content shape parses identically to the vendor-native shape. mcpd 777/777, cli 430/430.

The session would just start at \`> \` with no confirmation of the configuration. Now both REPL and one-shot modes print a banner to stderr listing: - agent name + description - LLM + project (if attached) - effective system prompt (or --system override) and any --system-append addendum, indented for readability - active sampling overrides (temperature, top_p, etc.) Goes through stderr so \`mcpctl chat ... -m "hi" 2>/dev/null\` keeps piping clean. Best-effort: a metadata fetch failure logs and lets the chat proceed rather than blocking.
