Overview

AI-generated overview

TopicGate is a local MCP server that gives an AI assistant secure local access to MQTT topics.

What you can do
Provides secure local access to MQTT topics through MCP, so an assistant can work with MQTT messaging from the user's own machine. The manifest lists no individual tools, so the exact operations available are not documented in the supplied material. It runs as a local stdio process rather than a remote endpoint.
When to use it
Consider it when an assistant needs to reach MQTT topics locally and you want that access mediated through MCP instead of exposing the broker directly.
Requirements
Runs as a local process on the user's machine, installed from the topicgate package on PyPI over stdio. Desktop only; no web executable. No authentication, environment variables or headers are declared, but an MQTT broker to connect to is implied by the purpose.
Before you install
The manifest declares no authentication, environment variables or headers, and no tool list or README is supplied, so what it can read or publish on MQTT topics cannot be verified. Review the package before installing and confirm which broker it connects to and whether it can publish or change topic data.

Installation

In SourceWeft

  1. Open TopicGate in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
