Best MQTT MCP Servers
MQTT is a lightweight messaging protocol for IoT devices that enables efficient communication in low-bandwidth, high-latency, or unreliable networks. It uses a publish/subscribe model and is designed for constrained devices and networks.
Why this server?
Allows interaction with MQTT clusters on EMQX Cloud or self-hosted clusters, enabling clients to list connected MQTT clients, retrieve client information, disconnect clients, and publish messages to MQTT topics
AlicenseBqualityCmaintenanceA Model Context Protocol (MCP) server implementation that provides EMQX MQTT broker interaction.Last updated424Apache 2.0Why this server?
Employs the MQTT protocol for real-time printer communication, allowing for job management and G-code command dispatch.
AlicenseBqualityAmaintenanceAn MCP server for controlling Bambu Lab 3D printers that enables users to manipulate STL files, slice 3MF files, and manage end-to-end print workflows directly from Claude. It provides real-time status monitoring, file management via FTPS, and printer control through MQTT for a focused, lean Bambu-only implementation.Last updated417957GPL 2.0Why this server?
Provides tools for publishing messages to MQTT topics and subscribing to MQTT topics to receive messages, with configurable broker connection settings including authentication and TLS support.
AlicenseBqualityDmaintenanceEnables 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.Last updated2MITWhy this server?
Enables the creation and management of MQTT hooks, allowing AI agents to interact with MQTT-based messaging and events alongside traditional webhooks.

Provides MQTT Sparkplug bridge for Industrial IoT integration, enabling secure communication with MQTT-based industrial automation systems through the SINT Protocol.
AlicenseAqualityCmaintenanceSecurity-enforcing MCP proxy that sits between an AI agent and any number of downstream MCP servers, intercepting every tool call through a capability-token policy gateway that can allow, deny, or escalate to human approval before the call reaches any real tool. It also exposes built-in operator tools for approval workflows, audit trail queries, token management, voice/HUD output, and hierarchicalLast updated219Apache 2.0Why this server?
Core integration allowing communication with IoT devices using MQTT protocol for publishing/subscribing to commands and responses
AlicenseBqualityFmaintenanceLinks IoT devices to AI large models using the MCP and MQTT protocols, enabling natural language control, real-time AI responses, and complex instruction execution for interconnected IoT devices.Last updated3370MITWhy this server?
Provides a built-in MQTT broker for mocking messaging topics and payloads.
Why this server?
Supports monitoring and debugging of the MQTT integration within Home Assistant, enabling searches for related entities and access to integration-specific debug logs.
AlicenseAqualityCmaintenanceEnhanced Home Assistant MCP server with 22 context efficient tools for smart home control, automation trace debugging, entity registry management, CEL expression queries, and long-term statistics.Last updated223MITWhy this server?
Supports MQTT protocol for telemetry and command communication with IoT devices.
AlicenseAqualityCmaintenanceEnables registration, monitoring, and control of IoT devices via AI agents, with local storage and no cloud API key required.Last updated9MIT
