"MQTT" matching MCP servers:

Provides MQTT communication capabilities for Large Language Models and other clients, enabling connections to MQTT brokers, publishing and subscribing to topics, and managing real-time messaging workflows.

MCP server that bridges MQTT sensor data to MCP, allowing clients to query cached sensor readings and send commands via tools like list_topics, read_topic, and publish.

Enables Cursor to subscribe to MQTT topics and read buffered messages from an MQTT broker.

Enables interacting with MQTT brokers to publish, subscribe, and manage connections, with a real-time web UI for visual feedback.

Enables AI assistants to publish and subscribe to MQTT topics with configurable transport options (STDIO, Streamable HTTP, SSE), supporting both local development and web deployments with flexible broker authentication.

Enables LLM agents to securely monitor and control MQTT devices for building automation, industrial control, and smart home systems through a standardized MCP interface.

Connects AI assistants to MQTT brokers for smart home automation and IoT device control, enabling topic discovery, sensor reading, command sending, and event monitoring.

Enables AI agents to query MQTT message history stored in SQLite, including topic inventories, last values, historical data, silent devices, and collector connection gaps. Supports publishing messages when write mode is enabled.

Enables LLM agents to interact with MQTT brokers through publish, subscribe, and query operations. Provides fine-grained topic permissions with wildcard support for secure IoT device communication and sensor data access.

Enables control of smart lights through MQTT messaging protocol, supporting operations like turning lights on/off and adjusting brightness levels from 0-100.

Enables agents to drive a Coreflux broker end to end over MQTT: running broker commands, publishing and subscribing to live topics, linting and deploying LoT/.lotnb files in order, uploading and exporting projects, tracing actions, and searching docs. Destructive operations are gated behind safety hooks, and no npm dependencies are required beyond Node.js 20+.

Enables MQTT broker operations like connect, subscribe, and publish through MCP over SSE transport.

Enables controlling and monitoring INSTAR IP cameras over MQTT, with tools to set and query camera settings, wait for state changes, check connectivity, retrieve snapshots, and list capabilities.

This MCP server enables AI agents to read MQTT and Sparkplug B data via tools like list_topics, get_latest, and read_all, providing read-only access to latest sensor values.

Enables AI agents to control monitor settings (brightness, contrast, input source) via DDC/CI protocol, with support for MQTT integration.

Enables MCP-compatible AI clients to safely control Home Assistant devices and query MQTT sensors through natural language, using allowlist-guarded actions and pre-defined automations.

An MCP server that lets AI models read and control industrial devices via standardized protocols like Modbus, OPC UA, and MQTT, with simulation and real hardware modes.

An MCP server that enables LLMs to list, inspect, and control Zigbee devices via the Zigbee2MQTT frontend websocket API, eliminating the need for direct MQTT broker access.

Enables Claude Code to see and drive Bambu Lab 3D printers over the local network via MQTT, providing status, file management, print control, filament, maintenance, and diagnosis without any cloud dependency.

MCP server for controlling LED displays via MQTT. It enables AI agents to list devices and send text, images, colors, or clear commands with authentication and permission checks.
