Tools & capabilities

Ethora MCP Server tools 89

  • ethora-configureSet the Ethora API URL and credentials for this MCP session. Stores values in memory only; each call merges with omitted fields kept. Alternative to env vars (ETHORA_API_URL / ETHORA_APP_JWT / ETHORA_APP_TOKEN / ETHORA_B2B_TOKEN). On a hosted server `apiUrl` is fixed and cannot be changed; credentials are per session. Auth: none required — this establishes auth material. Errors: only if a value is structurally invalid. Follow with an `ethora-auth-use-*` tool to pick the active mode.
  • ethora-statusReport the current Ethora MCP session state: configured API URL, active auth mode, which credentials are present (booleans like `hasAppJwt` — values never echoed), the selected appId/agentId, and `hosted`/`sessionId` on the hosted (Streamable HTTP) server. Auth: none required. Errors: effectively none. Related: `ethora-doctor` for an active connectivity check.
  • ethora-helpTask-oriented orientation for this MCP server: explains the three Ethora auth modes (user / app-token / B2B) and recommends next tool calls + recipes based on current session state. Auth: none required — inspects state, no API calls. Errors: effectively none. Related: pass a recommended recipe id to `ethora-run-recipe`.
  • ethora-run-recipeExecute a built-in recipe — an ordered sequence of this server's own tool calls — by id. Recipes capture common flows (B2B bootstrap, broadcast, sources ingest). Use `dryRun: true` to preview resolved steps. Omit `recipeId` to list runnable recipes for a `goal`. Requires: the inputs the chosen recipe lists; call without `recipeId` first to see the recipes and their required inputs. Auth: depends on the recipe's steps — configure those first (see `ethora-help`). Errors: stops at the first failing step and returns the partial log; a missing required `vars` entry fails fast before any step runs.
  • ethora-doctorDiagnose the session: validate the config is internally consistent for the active auth mode and ping the Ethora API (`GET /v1/ping`). Returns `{ state, checks, ping, suggestions }`. Auth: none required; report is tailored to whatever credentials are set. Errors: rarely throws — instead returns `suggestions` and a `ping.ok: false` block when the API is unreachable.
  • ethora-auth-use-appSwitch this session's active auth mode to app-token, so subsequent app-scoped calls authenticate with the configured `appToken`. Auth: requires an `appToken` to already be configured (via `ethora-configure`, ETHORA_APP_TOKEN env, or `ethora-app-select`). Errors: returns an error if no `appToken` is configured. Related: use after `ethora-app-select`.
  • ethora-auth-use-userSwitch this session's active auth mode to user-session, so subsequent calls authenticate as a logged-in Ethora user. Auth: the switch needs nothing, but user-auth tools only work once `ethora-user-login` stores a user token (login also needs a configured `appJwt`). Errors: none on the switch; downstream tools return 401 until login succeeds. Related: follow with `ethora-user-login`.
  • ethora-auth-use-b2bSwitch this session's active auth mode to B2B, so subsequent calls authenticate as a tenant actor via the `x-custom-token` header. Auth: requires a `b2bToken` (JWT with `type=server`) to already be configured (via `ethora-configure` or ETHORA_B2B_TOKEN env). Errors: returns an error if no `b2bToken` is configured. Related: server-side automation — pairs with `ethora-b2b-app-create`, `ethora-users-batch-create-v2`, `ethora-app-tokens-*-v2`.
  • ethora-app-selectSet the current app context for this session so app-scoped tools can omit their `appId` argument. Stores `currentAppId` and, if given, `appToken` (which defaults the auth mode to app-token unless `authMode` overrides). Auth: none required to set the context. Errors: effectively none — a non-existent `appId` is not validated here; the first app-scoped API call surfaces the 404. Related: pairs with `ethora-auth-use-app`.
  • ethora-chats-broadcast-v2Enqueue an asynchronous broadcast job posting a message to one or more chat rooms of an app — returns a `jobId`; messages are not sent synchronously. Targeting is exclusive: `allRooms`, `chatIds`, or `chatNames`, not a mix. Requires: a selected app with at least one room (`ethora-app-create-chat`). Auth: app-token mode OR B2B mode with an explicit `appId`. Errors: 401/403 wrong auth; 400 no target or conflicting targets; 404 unknown `appId` or room. Related: track with `ethora-wait-broadcast-job-v2`.
  • ethora-chats-broadcast-job-v2Fetch the current status and per-room results of a broadcast job by `jobId` (one-shot, no polling). Returns the job object with its `state` (pending/running/completed/failed). Requires: a selected app with at least one room (`ethora-app-create-chat`). Auth: app-token mode OR B2B mode with an explicit `appId` — must match the auth used to enqueue the job. Errors: 401/403 wrong auth; 404 unknown `jobId`. Related: `ethora-wait-broadcast-job-v2` for a blocking wait.
  • ethora-wait-broadcast-job-v2Block until a broadcast job reaches a terminal state (`completed` or `failed`) or until `timeoutMs` — read-only polling wrapper around `ethora-chats-broadcast-job-v2`. Returns `{ done, state, job }`, or `{ done: false, reason: "timeout" }` on timeout. Requires: a `jobId` returned by `ethora-chats-broadcast-job-v2`. Auth: app-token mode OR B2B mode with an explicit `appId` — must match the auth used to enqueue the job. Errors: 401/403 wrong auth; 404 unknown `jobId`.

Call this tool when building PubNub applications to ensure robust, scalable, and secure implementations.
  • manage_appsManages PubNub apps with operations: list, create, update. - 'list': List all apps on your account. - 'create': Create a new app. User must provide data.name. - 'update': Update an existing app name. User must provide data.id and data.name.
  • manage_keysetsManages PubNub keysets with operations: get, list, create, update. - 'get': Get a specific keyset information, including its current config (message persistence, App Context, files, presence including presence rules, etc.). User needs to provide the keyset id. - 'list': List all keysets for your account or a specific app. - 'create': Create a new keyset. New keyset is created with Message Persistence, App Context, Files, and Presence enabled by default; the user must provide name, production, and config with nested objects (messagePersistence, appContext, files, presence), and if any required parameter is missing, you must ask the user to provide it. - 'update': Update an existing keyset.
