Move MCP, chat and investigations into their own Worker (maple-ai) - #861
Merged
Conversation
Every empty list view in Maple said the same sentence — "No traces found" —
whether the user had never instrumented the signal, had instrumented it and
picked a quiet time range, or had filtered everything out. Those three need
opposite next steps, and nothing in the product could tell them apart, so
nothing gave advice.
Adds the signal that separates them, and the empty state that uses it.
API — GET /v2/instrumentation/signals reports, per signal (traces, logs,
metrics, sessions, product events), whether the org is sending it and when it
last arrived. Traces, logs and metrics come from the hourly service_usage
rollup rather than the raw tables, so it is cheap enough to call from anywhere.
Three invariants the UI leans on:
- It never fails. A warehouse outage returns 200 with every signal "unknown",
following SetupAuditService's catchCause precedent. An empty state that
500s the page it was added to help would be worse than the bare string.
- Every signal is always in the response. The union's branches are group-less,
so an unsent signal reports count 0 rather than dropping out — a caller
indexing by signal can treat a missing entry as a bug.
- The window is 30 days, and the wire contract says absence means "not
sending now", not "never sent".
Web — SignalEmptyState resolves four branches: filters active (wins over
everything, because the user narrowed the view themselves), never received
(setup route plus what actually produces the signal), received but quiet (says
when the last event arrived), and unreadable (states the fact, offers nothing —
advising setup to someone already set up is worse than silence). All copy lives
in one table so adding this to a page is picking a signal, not writing a
sentence.
Split into SignalEmptyStateView, which takes presence as a prop, plus a hook
wrapper: anti-slop(no-module-mocking) rules out vi.mock, so the tests inject
presence and render in a real memory router.
Wired into the three worst offenders, each previously a bare string in a table
cell: traces, logs and services. Logs keeps its own search and trace-scoped
copy — a narrow question deserves its narrow answer — and only the fallback
changed. Services lists services but is built on traces, so the heading uses
the page's noun while the timestamp uses the signal's.
Also registers the new builder in the benchmark catalog. QUERY_MODULES is an
explicit map, so a builder missing from it slips past the coverage gate
unnoticed.
A new v2 API group breaks every shared test harness that builds the whole
graph, hence the three test-support changes.

The in-app snippet is the fast path, but it is one framework's worth of instructions. Anyone on a language or setup it does not cover had nowhere to go from an empty page except a support chat. Each signal now carries a docs path alongside its copy, rendered as a secondary link beside the setup button. Traces, logs and metrics point at the instrumentation guide; sessions and product events at their own pages. Paths are stored relative rather than as full URLs so a test can resolve each one against the landing content collection. Docs links rot silently — nothing in a build notices a 404 — and this makes a renamed doc fail in the PR that renames it, naming the signal that broke. The test asserts it found a plausible number of pages first, so a wrong content root fails loudly instead of passing vacuously. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
… service filters Three fixes from CI and review. The iOS OpenAPI spec was stale — adding a v2 API group changes the generated tag list, and `ios:openapi:check` failed the quality job. Regenerated. Only the tag lands; the signals path is outside the curated mobile subset. The telemetry-signals wire example showed two signals while the contract promises all five, and that example is what OpenApi.fromApi renders into the public document. Added the missing three. The services table can be emptied by seven search params — three inclusion facets, three exclusion facets, and health — and both empty states omitted the filter flag, so a filtered-to-nothing table showed trace-presence guidance instead of offering to clear. Both now pass a derived flag and a reset that preserves the time range and grouping, neither of which is a filter. The clear action rebuilds search from the route's typed params rather than spreading `prev`: `prev` is the union of every route's params, so its `groupBy` widens to `string` and stops satisfying this route.

The settings nav had four uneven groups and thirteen rows, one group holding a
single item and one row ("API Reference") that was half of the API Keys page
filed as its own tab — it even passed a callback back to API Keys so it could
link there.
Nav:
- Four balanced groups: Workspace, Connections, Data, Alerting.
- Integrations leads Connections. It is a sibling page rather than a tab, and
the shell kept tabs and links in separate arrays and painted every tab first,
so a link could only ever land at the foot of its group no matter how it was
declared. Both now share one ordered list; position is declared, not derived.
- "API Reference" folded into the foot of the API Keys page. `?tab=developer`
redirects rather than blanking.
- The link id no longer widens the tab union, so /account keeps its narrow type,
and tab resolution filters links out of the visible-item list so /integrations
can never be picked as a fallback tab id.
API Keys:
- The tab counts were wrong. A key past its expiry is not revoked, so it counted
as Active, cued only by a badge and a date column both hidden below `md`.
Status is now one derived value and the list groups by it: Active, Expired,
Revoked, covered by api-key-status.test.ts.
- Keys inside their last week carry a badge in the name row and sort to the top.
- The restricted-scope picker was seventeen families times three levels with no
shortcuts. Adds All read / All write / Clear, a selected count, and a filter
that hides rows without touching their levels.
- The disabled Create button now names what is missing.
- Drops the toolbar docs link, which competed with the reference block below it.
KeyIcon is now Nucleo Arcade's pixel key, replacing the hairline key that read as
an arrow at nav size.

Preparation for extracting MCP, chat and the investigation fan-out into their own Worker. Four modules sat inside the AI surface while services that will stay in `apps/api` imported them, so the split could not be a clean cut. Each one moves to where both sides can reach it: - `chatSessionStub` and the Durable Object's RPC surface become `@maple/domain/chat-session-stub`. Its own file rather than the wire contract, because addressing the object means handling an unparsed namespace handle off a Worker env — the boundary marker belongs on that, not on the schemas. - `widthFor` joins `@maple/domain/investigation-fanout`, beside the payload whose `maxWidth` it computes. Its tests come with it. - `incident-context.ts` moves whole. The staying services and the moving agents build the same message, and two copies is how the wording silently drifts. - `McpToolSurface` joins `@maple/domain/mcp-manifest`, because the audit log records it and the audit log is read by code that runs no MCP. Also deletes the internal Worker-to-Worker RPC surface, which has had no caller since it was written: `apps/api/src/internal-rpc.ts`, `worker/rpc.ts`, their wiring, and the `MapleApiRpcContract` half of the domain module. What survived was never about RPC — a tool's advertised shape and the one failure any surface can provoke by naming a tool that does not exist — so it becomes `@maple/domain/mcp-tool-contract`, with `McpToolNotFoundError` tagged `@maple/mcp/ToolNotFoundError`. Nothing persists that tag on a wire; the only readers are three `catchTag` call sites in this repo. The remaining edges from staying code into the moving set are now exactly the four files that themselves move later: the two runtime graphs and the two chat route modules.

The settings nav and API Keys work landed on main as a squash merge (#860) while it also sits on this branch as its own commit, so the two histories conflicted in `api-keys-section.tsx`. Every conflicting hunk was the same shape: main carries the later iteration of this exact code — the live status clock, the `hasPendingStatusBoundary` helper that lets the timer stop itself, threading that one clock into `ApiKeyRow` so the badge cannot disagree with the bucket, and keeping the search input visible while a filter is applied. The branch side held the earlier draft and contributed nothing main lacks, so the resolution takes main's file verbatim. It is byte-identical to `origin/main`'s.

Included review availability: Your plan provides up to 4 included reviews per hour; 2 remain after this review.
First half of moving every agent surface out of apps/api: the MCP server and its tools, the chat agent and its Durable Object, and the investigation fan-out. They move together because they are one thing wearing three hats — all three reach the same tool registry in-process, so extracting any one alone leaves the registry behind. That is what made the September attempt worth 1%. Measured on the api's module graph before committing to this (rolldown, unminified, same tree). Dropping the MCP registry, the chat routes and the two hosted classes takes it from 11.74 MB over 85 chunks to 9.34 MB over 50, and module evaluation from ~336 ms to ~278 ms — ~40% of that on the http graph alone. The other half is per-request and not in those numbers: a `/mcp` call builds `AllRoutes` and `ApiAuthLive` today, and a `/v2` call builds 47 tool schemas. This commit is the skeleton only. It hosts nothing, serves `/health`, and changes no behaviour anywhere: apps/api still owns every AI route. Shaped after apps/alerting, which is the proven satellite-Worker form — single-module alchemy class, `__ALCHEMY_RUNTIME__`-guarded props, heavy graphs behind a dynamic import so module scope stays inside Cloudflare's upload-validation CPU budget. It carries the api's `strictExecutionOrder: false` override for the same reason the api does, because it will carry the same drizzle and Effect-Schema graph. Registration: yielded and dev-served from the root stack, `ai` added to DEV_APPS, to MapleDbConsumer so it gets its own Postgres connection budget, to knip's entries, and to the CI install filters. `workersDev: false` and no custom domain — it is reached only over a service binding, which is what will keep `/mcp` on api.maple.dev and its OAuth issuer and RFC 8707 resource identifiers unchanged. One prd prerequisite is recorded as a TODO rather than done, because it is not a code change: `ai` shares the `maple-prd` Hyperdrive config until a dedicated one is created in the dashboard. Their origin connection limits sum against PlanetScale's max_connections, and sharing api's pool is how api's connections got starved before alerting got its own.

The skeleton's fetch handler returned 200 "ok" for every path while its own comment and test said `/health`. Harmless today, since nothing routes here yet, but the point of landing the skeleton first is that the next phase moves real routes onto it — and a worker that 200s everything turns a mistyped path into a silent success instead of a visible 404. Matches the api's liveness check: GET `/health` only, answered without touching the layer graph, the database, or a binding, because a check that builds the graph reports the graph's health rather than the isolate's. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
WIP — the code has moved but nothing serves it yet. apps/ai still answers only /health, and apps/api no longer mounts the routes, so /mcp and the chat surface are dark until the worker wiring and the api forward land. Not pushable. The plan split this into three phases and that was wrong: chat and the investigation workflow reach the MCP tool registry in-process, so separating them would mean a cross-worker call per tool invocation. They move together. Alias convention, which took a wrong turn first: in apps/ai, `@/` is apps/api's source and `@ai/` is its own. That looks backwards until you notice this program compiles api's modules too, and those spell their internal imports `@/`. Pointing `@/` at apps/ai resolved every one of them into the wrong tree — 1015 errors. apps/alerting already had it right. The chat HTTP group moved out of MapleInternalApi into its own MapleAiApi: an HttpApi must be implemented in full by whoever builds it, so a group cannot straddle two Workers. Paths are unchanged, since api will forward /internal/chat/* here, so this is a change of which Worker answers rather than of what the dashboard calls. apps/web gains a matching atom client and its one call site moves across. Two things surfaced that were not part of the plan: `buildIsolateHandler`'s guard was vacuous. It exists to reject services a raw route reads from the request context — the bug that took chat down in September — but `McpLive` widened the whole route composition to `any`, so the constraint held over nothing. With MCP gone the `any` went, the guard bound for real, and it immediately caught the chat group. Its output parameter is now open, with the requirement side left exactly as strict as it was meant to be. apps/api excludes tests from tsc. Mirrored here rather than fixing the 47 type errors that exclusion has been hiding, because that is a decision about api's config too, not something to change while relocating files. Boundary tests followed their subjects: the MCP and chat entrypoint assertions now live in apps/ai, and AlertReadModelsService keeps its route half in api while the tool half moves. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Completes the move. maple-ai now hosts what it was given: the MCP transport and its tools, the chat Durable Object and its routes, and the investigation fan-out Workflow. apps/api forwards `/mcp`, `/api/chat/*` and `/internal/chat/*` over a service binding, ahead of building its route graph — which is the point, since a `/mcp` call no longer builds `AllRoutes` and `ApiAuthLive`, and a `/v2` call no longer builds 47 tool schemas. The public address does not move. `api.maple.dev/mcp` still answers, so the OAuth issuer and the RFC 8707 resource identifiers stay on api's origin and no registered MCP client is invalidated. The forward is byte-transparent through alchemy's Fetcher: same method, original Host, every header, both bodies as streams — the chat tail is an open `text/event-stream`, so buffering either side would turn a live transcript into a hang. api answers OPTIONS before forwarding and maple-ai emits no CORS headers of its own, because two `access-control-allow-origin` headers is a hard browser failure rather than a merge. Details worth knowing: - The MCP tool rate limiter moved with its `namespaceId` unchanged. It is the Cloudflare-side identity of the bucket, so a new one would silently reset every client's budget at the cutover. The OAuth limiter stayed with OAuth. - The AI Gateway keeps the resource name `maple-api-ai`; only its alchemy logical id moved. Renaming mints a new gateway and abandons its analytics. - The raw-route guard is ported verbatim. It is worth more here than in api: this Worker is almost entirely raw routers, and it is what turns "reads a service per request" into a build failure instead of a runtime 500 on every request — the September chat outage. - The OAuth-to-MCP seam is tested again, on the side that would break. api mints a token, maple-ai resolves it, and refuses it for a resource it was not bound to. That contract now crosses Workers and nothing else pinned it. CI follows the code: token-cost watches apps/ai/src/mcp, evals run against @maple/ai, and the Slack approval-list canary triggers on apps/ai. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
…g it Without this the prd deploy fails before it uploads anything. Dropping a locally hosted Durable Object class while keeping a cross-script reference to it is the shape that silently destroys a namespace, so alchemy refuses it outright with `DurableObjectTransferRequired` — a safe failure, but a red deploy, and the two ways out are a transfer or a downtime window with the binding removed entirely. `transferredFrom: "api"` takes the first: alchemy runs a `transferred_classes` migration and live chat transcripts follow the class to maple-ai. One merge, no downtime, nothing stranded. The property is inert once every stage has moved, so it stays rather than being cleaned up later and stranding whichever stage lagged. That needs the props-carrying class form, since the single-argument overload takes an implementation and no props — hence `ChatSessionLive` beside the class, and `MapleAi` declaring the class in its contract so the host provides it. Two inference details worth keeping, because both fail far from their cause: - `.make<never>(…)`. The activation only needs `DurableObjectServices`, which `.make` already discharges, but inference otherwise widens them into the layer's own requirements and `DurableObjectState` surfaces in alchemy.run.ts. - The root provides the Live layer where it yields the Worker. That is a genuine entry point, so the lint rule about `Effect.provide` is suppressed there rather than worked around. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
CLAUDE.md gains a section on the AI Worker and loses a stale one: the LLM core paragraph still named `@opencode-ai/ai`, removed by 520af87 and replaced with Effect AI and `@effect-agent/*`. The sandbox tool paths and the `bun dev` app list move with the code. The alias convention gets called out explicitly, because it reads backwards and cost a thousand type errors to learn: in apps/ai, `@/` is apps/api's source and `@ai/` is its own. That program compiles api's modules, and those spell their internal imports `@/`. docs/infra.md records the measurements the decision rested on, so a third pass starts from numbers instead of re-deriving them, plus the two migration facts that bite at deploy time rather than at compile time — the Durable Object carries a transfer, and the Workflow cannot. `maple-ai` joins PRD_LOCKSTEP_REVISION_SERVICES, since it now deploys with the rest. NOTE FOR WHOEVER MERGES: the skew alert's SQL lives in the production database, not this repo, and has to list `maple-ai` too. Until it does, a maple-ai that misses a deploy goes unnoticed — the constant and the rule are coupled by nothing but this note and `env.test.ts`. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Conflicts in api's AI-session observability routes, which stay in api.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The job measures the MCP tool definitions, which moved to apps/ai, so it now runs `--filter @maple/ai`. But the tools reach api's services through a path alias, and those modules resolve `@maple/domain/*` out of apps/api's own node_modules — which a scoped install that omits `@maple/api` never creates. Head measurement died on the first such import, leaving no head.json for the summary step to read. The base measurement also swaps in the base commit's sources, and on a base older than the split there is no apps/ai at all. It reads 0 either way and the delta is the whole cost, once; the pathspec now includes apps/api/src so the swap is complete rather than half-applied when the base does have both.

Three separate pieces of work accumulated on this branch. They are independent and can be reviewed in any order; the commits are clean, so reviewing commit-by-commit is easier than reviewing the combined diff.
Empty states (3 commits)
Tells "this signal was never wired up" apart from "it is wired up but the window is quiet", links each signal's empty state to its docs page, regenerates the iOS spec, completes the example, and makes the states respect the active service filters.
Settings navigation (1 commit)
Regroups the settings nav and reworks the API Keys page.
AI/domain seam split (1 commit, new in this session)
Groundwork for moving the MCP server, the chat agent and the investigation fan-out out of
apps/apiinto their own Worker. No behaviour change.Four modules sat inside that AI surface while services which will stay in
apps/apiimported them, so the eventual extraction could not be a clean cut. Each moves to where both sides can reach it:chatSessionStuband the Durable Object's RPC surface become@maple/domain/chat-session-stub. It gets its own file rather than joining the wire contract, because addressing the object means handling an unparsed namespace handle off a Worker env, and the boundary marker belongs on that rather than on the schemas.widthForjoins@maple/domain/investigation-fanout, beside the payload whosemaxWidthit computes. Its tests move with it.incident-context.tsmoves whole. The staying services and the moving agents build the same message, and keeping two copies is how the wording silently drifts.McpToolSurfacejoins@maple/domain/mcp-manifest, because the audit log records it and the audit log is read by code that runs no MCP.The commit also deletes the internal Worker-to-Worker RPC surface, which has had no caller since it was written: the api-side entry point, its worker wiring, and the contract half of the domain module. What survived that file was never about RPC, just a tool's advertised shape and the one failure any surface can provoke by naming a tool that does not exist, so it becomes
@maple/domain/mcp-tool-contract.One thing worth a reviewer's attention
McpToolNotFoundError's tag changes from@maple/internal-rpc/ToolNotFoundErrorto@maple/mcp/ToolNotFoundError. Nothing persists that tag on a wire and it is not in the anticipated-errors list; the only readers are threecatchTagcall sites, all updated here. Worth a second pair of eyes in case there is a consumer outside this repo.Verification
Typecheck and lint clean across
apps/apiandpackages/domain. 814 tests pass across the mcp, chat, workflows, runtime, audit and errors areas, plus all 711 domain tests.The boundary this commit exists to create now holds: the only remaining imports from staying code into the moving set are the four files that themselves move later, namely the two runtime graphs and the two chat route modules.
