FAQ from EMQX MCP Server

How do I set up an EMQX cluster to use this server?

You can use EMQX Cloud Serverless (free), EMQX Cloud Dedicated, or a self-hosted EMQX Platform. All require a configured API Key and client authentication.

Does the `subscribe_mqtt_topic` tool work with self-hosted EMQX?

No, the subscribe tool uses an SSE endpoint that is only available on EMQX Cloud deployments. Self-hosted deployments may not support it.

What environment variables are needed?

EMQX_API_URL (your cluster’s API v5 endpoint), EMQX_API_KEY, and EMQX_API_SECRET must be set for the server to authenticate.

Can I filter clients by IP address or username?

Yes, the list_mqtt_clients tool supports filtering by node, client ID, username, IP address, connection state, and more, including fuzzy search patterns.

What is the maximum number of clients I can retrieve in one call?

The list_mqtt_clients tool accepts a limit parameter with a maximum of 10,000 results per page.
