# manage-mqtt-brokers Discover, inspect, and switch between saved MQTT broker profiles in TopicGate. ## MCP server not available If the `topicgate` MCP server is not connected or its tools cannot be found, stop and tell the user: > The TopicGate MCP server is not active.

Do not attempt to call any other tool as a substitute. ## Tools | Tool | Mode | Purpose | |---|---|---| | `list_brokers` | read-only | List all saved broker profiles (UUID, name, host, port, active flag).

Omit `broker` to query the active profile. | | `activate_broker` | control | Switch to a different broker profile.

Call `get_connection_status` with a broker UUID or name (or omit for the active one). 3. Report connection state, dropped messages, and update interval. ## Switching brokers (control mode) `activate_broker` is only available when the server runs with `--mode control`. 1. Call `list_brokers` to confirm the target profile exists. 2. Call `activate_broker` with the broker UUID or name. 3. Verify with `get_connection_status` if the user wants confirma
