Description

This MCP server bridges Model Context Protocol clients with EMQX MQTT clusters (EMQX Cloud or self-hosted), enabling programmatic management of MQTT clients and topic publishing. It supports listing and filtering connected clients, retrieving detailed client information, forcibly disconnecting clients, and publishing messages with QoS and retain options. The project integrates with Claude Desktop and can run via Docker or the uv runtime, requiring EMQX API credentials to connect to the broker.
