mcp-server-matrix

A Model Context Protocol (MCP) server for Matrix — the open, decentralized communication protocol.

Built on matrix-nio, this server lets any MCP-compatible AI assistant (Claude, OpenClaw, etc.) send and read messages, manage rooms, and interact with any Matrix homeserver (Synapse, Dendrite, Conduit).

Read messages: "What are the latest messages in #general?"
Send messages: "Send 'Hello everyone!' to #announcements"
Manage rooms: "Create a room called 'Project X' and invite @alice:matrix.org"
Get info: "How many members are in #team-chat?"

Supported Homeservers

Tested with:

Synapse (reference implementation)
Should work with any spec-compliant homeserver (Dendrite, Conduit, etc.)

Requirements
