From b6df51d2bde0ad3b91f9faccb743826459fd6d44 Mon Sep 17 00:00:00 2001 From: Justin Carlson <40642470+justcarlson@users.noreply.github.com> Date: Sat, 26 Sep 2026 04:44:30 +0000 Subject: [PATCH 01/31] Render integration capability descriptions in the execute inventory The execute tool description and skill listed connected integrations as bare slugs, so an agent seeing a fresh session could not tell what each integration is for without spending sandbox calls on discovery. Each inventory line now carries the integration's catalog description, truncated to one scannable line (120 chars, word edge, first line only). Legacy rows whose description merely repeats the slug or display name stay bare. Descriptions remain user-editable data (PATCH /api/integrations/:slug), so deployments tune the wording without a rebuild. parseIntegrationInventory tolerates the optional suffix, so hosts deriving search_ tools from the description see the same slugs. --- .../core/execution/src/description.test.ts | 60 +++++++++++++--- packages/core/execution/src/description.ts | 71 ++++++++++++++++--- 2 files changed, 109 insertions(+), 22 deletions(-) diff --git a/packages/core/execution/src/description.test.ts b/packages/core/execution/src/description.test.ts index 365f115585..80066e4a7e 100644 --- a/packages/core/execution/src/description.test.ts +++ b/packages/core/execution/src/description.test.ts @@ -38,8 +38,9 @@ const SLACK = IntegrationSlug.make("slack"); const TEMPLATE = AuthTemplateSlug.make("apiKey"); // The execute description lists the top-level integrations the user has -// connected: one bare line per integration slug, deduped across connections, -// names only (no per-integration descriptions). +// connected: one line per integration slug, deduped across connections, with +// the integration's capability description when the catalog carries a real one +// (legacy slug/name-only descriptions are suppressed). const githubPlugin = definePlugin(() => ({ id: "github-plugin" as const, credentialProviders: [memoryProvider()], @@ -118,7 +119,7 @@ describe("buildExecuteDescription", () => { }), ); - it.effect("lists integration names only, with no descriptions", () => + it.effect("renders capability descriptions, suppressing slug/name repeats", () => Effect.gen(function* () { const executor = yield* createExecutor( makeTestConfig({ plugins: [slackPlugin, githubPlugin] as const }), @@ -142,12 +143,10 @@ describe("buildExecuteDescription", () => { const description = yield* buildExecuteDescription(executor); - // Bare slugs, sorted, with no per-integration description riding the line - // (Slack's "Send and read workspace messages." is dropped). - expect(description).toContain("- `github`"); - expect(description).toContain("- `slack`"); - expect(description).not.toContain("Send and read workspace messages"); - expect(description).not.toContain("- `slack` —"); + // Slack's real capability description rides its line; github's legacy + // description ("GitHub", a name repeat) is suppressed. + expect(description).toContain("- `slack` — Send and read workspace messages."); + expect(description).toContain("- `github`\n"); expect(description).not.toContain("- `github` —"); }), ); @@ -179,6 +178,45 @@ describe("buildExecuteDescription", () => { }), ); + it.effect("truncates long descriptions to one scannable line", () => + Effect.gen(function* () { + const verbosePlugin = definePlugin(() => ({ + id: "verbose-plugin" as const, + credentialProviders: [memoryProvider()], + storage: () => ({}), + extension: (ctx) => ({ + seed: () => + ctx.core.integrations.register({ + slug: IntegrationSlug.make("verbose"), + name: "Verbose", + description: `${"word ".repeat(60).trim()} trailing\nsecond line ignored`, + config: {}, + }), + }), + }))(); + const executor = yield* createExecutor( + makeTestConfig({ plugins: [verbosePlugin] as const }), + ); + yield* executor["verbose-plugin"].seed(); + yield* executor.connections.create({ + owner: "org", + name: ConnectionName.make("main"), + integration: IntegrationSlug.make("verbose"), + template: TEMPLATE, + value: "verbose-token", + }); + + const description = yield* buildExecuteDescription(executor); + const line = description.split("\n").find((l) => l.startsWith("- `verbose`")) ??

With 3077 tools and 1381 rules, MCP `search` spent 5-8 s of CPU per call in policy resolution. - policies: add prepareToolPolicies. It sorts once, splits once, looks up exact patterns in a Map and buckets wildcard patterns by first segment. It returns the same match as resolveToolPolicy, including owner order and ties. - executor: the global rule set carries the prepared resolver; tools.list resolves synchronously per tool; provider rules sort once. - tools.schema reads only rules that can match the tool (its exact pattern or any wildcard) and accepts { typeScript: false } to skip the TypeScript preview. - MCP passthrough search/invoke request JSON Schema only. Tests compare the prepared resolver with resolveToolPolicy and resolveEffectivePolicy on explicit precedence cases and 300 seeded random rule sets, and check list/schema visibility with narrowed rule reads.

Models spent another round trip finding the slug. - resolveIntegrationAlias: exact slug; then a slug or display name equal once case and separators are dropped; then every alias word found in the slug or name; last, every word found in the description. One match is used and reported as `integration`; several candidates are all searched and reported as `integrations`; no match keeps the value as an exact filter and adds a `hint`. - searchTools accepts `integrationAliases`: display-name words the slug lacks, scored as part of the integration field so a query such as "scrapecreators profile" ranks that integration's tools. Alias text only adds signal; every query without an alias returns the same ids. - Parameter descriptions and the search-invoke guide explain it. Local measurement (3051-tool fixture catalog): `integration: "cloudflare"` 0 -> 25 hits, `"Cloudflare API"` 0 -> 25, `"vercel"` 0 -> 35, ambiguous `"api"` 0 -> 54 across both candidates. 11 of 11 non-alias queries return identical hit ids before and after.

Keep the database within its existing private access boundary. + +Response bytes count the complete serialized JSON-RPC response in UTF-8, before +HTTP/SSE framing or compression. Duration ends after transport send completes. +The fixed hidden-tool refusal is counted as `blocked`; this includes unknown +addresses because the existing response deliberately combines both cases. +Transport failures and abandoned calls count as `error` (zero response bytes +when no response was produced). Results and policies keep their existing behavior. + +The observer uses public SDK transport callbacks. It does not inspect SDK +private fields or change search, schema, catalog refresh, or encrypted secrets. +PRs #17 and #18 and the refresh work for issue #8 can merge in either order. + +The `executor_tool_usage` table shares the existing libSQL client with the +host. No second write connection opens. Writes run in batches once per second, +with at most 1,024 queued events and 1,024 active tracked calls per MCP session. +Retention runs at startup, each flush, and hourly while idle: seven days and +at most 100,000 rows. SQLite reuses deleted space; the table reaches a bounded +high-water size. A shutdown drains the queue. A crash can lose up to one second +of queued metrics; a busy or unavailable database can lose more. Queue overflow +and failed batches increment durable loss counters on the next successful +flush. An initialization failure disables metrics for that process and emits a +fixed warning. Never interpret a partial window as a complete historical rank. + +Agents default to traffic class `agent`. Benchmarks and probes can send +`x-executor-traffic-class: benchmark` or `monitor`. Only these fixed values +survive; all other values become `agent`. This is a caller-supplied traffic +label, not an authenticated client identity. + +Read the summary locally with database read permission: + +```sh +bun run apps/host-selfhost/scripts/tool-usage-summary.ts \ + --db /path/to/executor.db \ + --from 2026-10-01T00:00:00Z --to 2026-10-08T00:00:00Z \ + --traffic agent --limit 20 +``` + +The CLI opens SQLite read-only. It emits JSON with top tools and integrations ranked by calls, +status counts, nearest-rank p50/p95 duration, and total response bytes for the +half-open time window. It also reports retention limits, oldest/newest retained +timestamps, and cumulative loss counters. It omits member pseudonyms. The +default window is seven days; `--traffic all` includes probes. Integration ranks combine invoke targets by integration slug to rank adapters. Only retained events can be summarized. + +Measure request overhead locally: + +```sh +BENCH_SAMPLES=5000 bun run apps/host-selfhost/scripts/bench-tool-usage.ts +``` + +The benchmark compares warm real SDK calls with observation disabled/enabled, +using the same response sizes and HTTP-equivalent JSON serialization. It uses +a disposable WAL SQLite database, nearest-rank percentiles, and batches of 256. +Request latency excludes the background flush; amortized flush time is reported +separately. Small timing differences can include JIT and scheduling noise. +It does not measure network latency or production database contention. diff --git a/apps/host-selfhost/src/mcp/session-store.ts b/apps/host-selfhost/src/mcp/session-store.ts index f9d29b1f05..f0738c3064 100644 --- a/apps/host-selfhost/src/mcp/session-store.ts +++ b/apps/host-selfhost/src/mcp/session-store.ts @@ -1,4 +1,4 @@ -import { Layer } from "effect"; +import { Effect, Layer } from "effect"; import { makeConsoleMcpErrorReporter, makeMcpBuildServer } from "@executor-js/api/server"; import type { McpErrorReporter } from "@executor-js/host-mcp"; @@ -12,6 +12,8 @@ import { selfHostAnalytics } from "../analytics"; import { ErrorCaptureLive } from "../observability"; import { SelfHostDb, type SelfHostDbHandle } from "../db/self-host-db"; import { SelfHostExecutionStackLayer } from "../execution"; +import { makeToolUsageRecorder } from "./tool-usage-store"; +import { observeToolUsageServer } from "./tool-usage"; // --------------------------------------------------------------------------- // Self-host McpSessionStore wiring.

For an API key that meant a second hash, lookup and `lastRequest` write on every request. Read the member row directly with the user id the first verification already produced. A bearer that last resolved as an API key is remembered by digest and tried as an API key first on the next request, skipping the OAuth-token and session-token lookups that can never match it. The key itself is still verified against the database on every request; a revoked key fails on the next request and is forgotten. Answer the standalone `GET /mcp` stream with 405 when the negotiated client capabilities admit no server-initiated message (no elicitation, sampling, roots, or MCP Apps UI), as the streamable-HTTP spec allows and as the client SDKs expect. Clients that declared any of those still get the stream. Spans now cover the authentication steps.

Sessions, API keys and OAuth tokens are not revoked on removal, so removal had no effect on access. Every seam now reads the caller's member row in the instance organization on every request, after the credential resolves, through one shared direct adapter read (auth/membership.ts). No row — or a lookup failure — denies: - API plane and MCP fallback (identity seam): NoOrganization, 403 - mcp() OAuth bearer: unauthorized, 401 with the challenge - account plane (me / API keys): 401 / 403 - browser-approval plane (/api/mcp-sessions/*): 403 Removal denies the next request; re-adding restores access on the next request with the same credentials; a role change (admin -> member) takes effect on the next request. The workspace role comes from the same row, so this stays one member read per request. Tests: the security review's six-assertion release gate, plus API-key, bearer-session, session-cookie and OAuth paths, role downgrade, account and approval planes, and re-add.

Move the alias resolver into @executor-js/execution (the host re-exports it) and resolve `namespace` against the integration catalog inside searchTools: an unambiguous alias becomes the slug for enumeration and ranked search; an exact slug, an ambiguous alias and an unknown name keep the token-prefix behaviour, so existing results do not change. Catalog display-name words also rank an integration's tools, as they already do in passthrough. The passthrough discovery object carries no catalog and is unchanged.

Telemetry on 2026-10-08 showed the skill read 185 times for 908 invokes. Add 768-byte codemode instructions that mirror the passthrough recipe: search with a namespace (slug or alias) and limit 3, then call the hit's path; describe only when the argument shape is unknown; read the skill once for files, emit, pagination and resume. The skill workflow now starts the same way. Passthrough text is unchanged.

A member saw integrations whose tools its org blocks or its host scope omits, and a tools.search under them returned nothing. buildExecuteDescription now reads tools.list({ includeAnnotations: false }) once (the same policy-filtered read tools.search serves), keeps only the connection slugs with at least one visible tool, and renders the same block: format, ordering, cap, overflow marker, and empty behaviour are unchanged. A failed tools read logs a warning and falls back to the unfiltered list so session init never fails on it. The describe span gains executor.connection_hidden_count (-1 on fallback).

The execute result now carries the distinct connected tool paths the engine already collected (`structuredContent.toolPaths`, first-call order; `toolName` is unchanged), and the transport observer records one `mcp_tool = 'execute'` row per distinct valid path, or one row with no target when the code called none. Each row carries the whole execution's status, duration and response bytes. Code, arguments, logs and results are never read. Migration: SQLite cannot alter a CHECK in place, so `initializeToolUsage` reads the stored definition from `sqlite_master` and, when it does not list `'execute'`, rebuilds `executor_tool_usage` once inside the same write batch: create `executor_tool_usage_new` with the new definition, copy every row with its id, drop the old table, rename, and recreate the time index. The `executor_tool_usage_state` table and its salt are untouched. A second initialize is a no-op. The integration ranking counts `execute` rows beside `invoke`.
