Phoenix agent bridge

+

+ This page embeds Phoenix and drives it over postMessage, the same way an + external application or AI agent would. Serve this page over http from + localhost on a different port than Phoenix (for example + npx http-server examples -p 8080). Opening it as a file:// + page will not work: that origin is opaque ("null") and Phoenix refuses + it. Click initialize first; only an initialized client receives the + event stream. +

Session + state (who completed `initialize`) belongs to the bridge. + - Why peers and not an id-to-window map: JSON-RPC ids are only unique per + client (two clients both start at 1), so an id-keyed map misroutes replies. +- `origin-policy.ts`: `OriginRule = string | (origin) => boolean`, + `ANY_ORIGIN = '*'`, `isLoopbackHostname`, `isLoopbackOrigin`, + `isOriginAllowed`. All checks parse with `URL`; no substring or regex matching. +- `post-message-transport.ts`: `PostMessageTransport` over window `message` + events. Drops disallowed origins and messages without a usable + `event.source`; hands the bridge one peer per sender window (a `WeakMap`, so + closed or removed windows are never kept alive); a peer posts only to its own + window with the verified origin as `targetOrigin`. +- `agent-bridge.ts`: `createAgentBridge(host, options)` returning + `{ dispose(), resubscribe() }`. Options: `transport?`, `origins?: +OriginRule[]`, `window?`, `allowMutations?` (default true). +- Sibling `enum-sources.ts`: `resolveEnumSources(host)` returns + `{ collections, presetViews, eventKeys, geometryParts }` from the live + display. Never throws. + +App wiring (`phoenix-ui-components`): `AgentBridgeService` (root) plus +`provideAgentBridge(config?)`, an `EnvironmentProviders` built with +`provideAppInitializer`. The phoenix-app adds `provideAgentBridge()` to +`AppModule.providers`. No component touches the bridge. + +Demo: `examples/agent-bridge-demo.html`. + +## Data flow + +All messages are JSON-RPC 2.0. Every response goes to the requesting client +only. + +**initialize** (required for the event stream; `tools/list` and `tools/call` +work without it): + +``` +-> {jsonrpc:"2.0", id, method:"initialize"} +<- {jsonrpc:"2.0", id, result:{ protocolVersion, serverInfo:{name:"phoenix", version}, + capabilities:{tools:{}}, toolCount }} +``` + +**tools/list**: `inputSchema` is plain JSON Schema. The internal `enumSource` +keyword is never emitted; parameters backed by a live source (`collection`, +`view`, `eventKey`, `part`) carry a concrete `enum` of current values, or no +`enum` when that source is empty. The conversion is the NL layer's own +`toArgsSchema` (through `buildIntentSchema`), so tools/list and the model +grammar always agree. + +``` +-> {id, method:"tools/list"} +<- {id, result:{ tools:[ {name, description, inputSchema, mutates}, ... ] }} +``` + +**tools/call**: + +``` +-> {id, method:"tools/call", params:{ name, arguments }} +<- {id, result:{ isError:false, content:[{type:"text", text}], structuredContent: }} +``` + +**phoenix/event** (notification on every command execution, from any source, +sent only to clients that completed `initialize`): + +``` +<- {jsonrpc:"2.0", method:"phoenix/event", params:{ name, args, result }} +``` + +## Error handling + +- Origin not allowed, or no `event.source` to answer: dropped silently, no reply. +- Not a JSON-RPC request (including JSON-RPC responses): ignored, never answered + (so two bridges cannot ping-pong). +- Notification (no `id`): never answered and nothing runs (JSON-RPC 2.0 section + 4.1; MCP defines every served method as a request). +- `id` present but not a string or finite number (including `null`): `-32600` + with `id: null`. +- Unknown method: `-32601`. Unknown tool or missing name: `-32602`. +- Command fails at runtime or fails validation: `tools/call` result with + `isError:true`. +- Mutation refused by policy: `isError:true` with a clear message. +- A reply the client cannot receive (for example a `DataCloneError`): `-32603` + to that client instead of leaving it waiting. + +## Lifecycle + +- `provideAgentBridge()` runs once at application startup, independent of the + command palette and of `uiConfig.showCommandPalette`. The bridge lives as long + as the app; `AgentBridgeService.ngOnDestroy` disposes it with the root + injector. +- `enable()` disposes any previous bridge first, so there is never a second + window listener. `enableFromLocation()` is a no-op when already enabled. +- `EventDisplay.init()` calls `cleanup()`, which clears every event-bus + subscriber. Every route change re-initialises the one root display, which + would silently cut `phoenix/event`. The service therefore calls + `handle.resubscribe()` from an `afterEveryRender` hook (idempotent, two map + operations); a client re-sending `initialize` also re-attaches it. A cleaner + long-term fix is in `EventDisplay` itself (keep app-lifetime subscribers + across `cleanup()`, or expose an init hook). +- Zones: the window listener is registered outside Angular's zone, so messages + from unknown origins never trigger change detection; accepted messages are + delivered inside the zone so commands that update Angular UI still render. + +Why app-level and not library-level: other experiments embed +`phoenix-ui-components`. Making `PhoenixUIModule` start the bridge by itself +would give every embedder an inbound control channel it never asked for. +`provideAgentBridge` is the idiomatic Angular 20 opt-in (like +`provideHttpClient`): an app that does not add it has no listener at all. + +## Security posture + +- Default OFF: no listener exists unless the app adds `provideAgentBridge`. +- `provideAgentBridge({ origins })`: exactly those origins (an explicit `'*'` is + honoured only here, never produced by the URL switch). +- `provideAgentBridge()` with `?agent=1`: only when the page itself is served + from `localhost`, `127.0.0.1` or `[::1]`, and then only for loopback origins + (`http:`/`https:` on those hosts, any port). The switch must be + unambiguous: `agent=1&agent=0`, or a search and a hash query that disagree, + stay dormant. The app uses path routing, so the switch is normally in the + search string. +- The opaque `"null"` origin is never admitted, under any rule: a sandboxed + `srcdoc` iframe gets it for free, and a reply to it would need targetOrigin + `'*'`. +- A missing, empty or non-array allowlist admits nobody; a malformed entry + admits nothing; a matcher that throws denies. +- Responses go only to the requester; events only to initialized clients. + Sending a message enrolls nobody in anything. +- Every call still goes through `registry.execute`, so schema validation and + the registered-command whitelist apply unchanged. +- Residual: with `?agent=1` any local web app on any loopback port can drive the + dev server, including reading loaded data with `get-object`. That requires + code already running on the developer's machine. + +## Physics safety + +Unchanged and by construction: the bridge exposes the same registry with the +same validation. An external agent cannot invent a command, pass invalid +arguments, or reach any method not deliberately wrapped as a deterministic +command.
