Tools (15)

• ably_get_channel_history

  Retrieve historical messages published to a channel, newest-first by default. REST: GET /channels/{channel}/messages.

• ably_get_presence

  List the members currently present on a channel (who is online now). REST: GET /channels/{channel}/presence.

• ably_get_presence_history

  Retrieve historical presence events (enter/leave/update) for a channel. REST: GET /channels/{channel}/presence/history.

• ably_get_channel_details

  Get status and occupancy metrics for a single channel (connections, publishers, subscribers, presence members). REST: GET /channels/{channel}.

• ably_list_channels

  Enumerate channels that are currently active in the app. Requires the API key to have the 'channel-metadata' capability. REST: GET /channels.

• ably_get_stats

  Retrieve message/connection/channel usage statistics for the app tied to the API key, bucketed by time. REST: GET /stats.

• ably_get_service_time

  Return the current Ably service time in ms since epoch. Useful for aligning start/end windows to the server clock. REST: GET /time.

• ably_publish_message

  WRITE: publish a message to a channel. Every connected subscriber receives it in real time. This is a real, outward-facing side effect — confirm the channel and payload before calling. REST: POST /channels/{channel}/messages.

• ably_whoami

  Return details about the configured control token: the account and user it belongs to and its capabilities. Good first call to confirm control-plane access. Control API: GET /me.

• ably_list_apps

  List all apps in the account (id, name, status, tls-only). Account id is resolved automatically from the control token when ABLY_ACCOUNT_ID is unset. Control API: GET /accounts/{account_id}/apps.

• ably_list_keys

  List the API keys for an app, including their capabilities (but not the full secret). Control API: GET /apps/{app_id}/keys.

• ably_list_namespaces

  List the channel namespaces (channel-rule prefixes) configured for an app, e.g. persistence and push settings. Control API: GET /apps/{app_id}/namespaces.

• ably_list_queues

  List the Ably Queues (AMQP/STOMP message queues) provisioned for an app, with their state and messaging stats. Control API: GET /apps/{app_id}/queues.

• ably_list_rules

  List the integration rules (reactor rules: webhooks, AWS Lambda/SQS/Kinesis, Kafka, Pulsar, etc.) configured for an app. Control API: GET /apps/{app_id}/rules.

• ably_get_account_stats

  Retrieve aggregated usage statistics across the whole account, bucketed by time. Account id is resolved from the control token when ABLY_ACCOUNT_ID is unset. Control API: GET /accounts/{account_id}/stats.
