Compatible with every major AI agent and IDE
What is the Matrix/Element MCP Server?
Connect your Matrix account to any AI agent and take full control of your decentralized communications through natural conversation.
What you can do
- Room Management — Create, join, knock, or leave rooms using simple commands like
create_roomandjoin_room. - Messaging & Events — Send messages or custom events to any room with transaction tracking via
send_message. - State Synchronization — Use
sync_clientto fetch the latest state from the homeserver and stay updated on all conversations. - User Discovery — Search the global user directory using
search_user_directoryto find and connect with others. - Account Control — Manage your profile, change passwords, or handle account registration and deactivation.
- Encryption & Keys — Handle cryptographic keys (
upload_keys,query_keys) for secure, end-to-end encrypted communication.
How it works
- Subscribe to this server
- Provide your Matrix Homeserver URL and Access Token
- Start orchestrating your chats from Claude, Cursor, or any MCP-compatible client
Who is this for?
- DevOps Engineers — automate alert rooms and incident response directly from the terminal.
- Privacy Advocates — maintain secure, decentralized communication without leaving your AI workflow.
- Community Managers — manage room states and user interactions across large Matrix networks.

Frequently asked questions
How do I see the latest messages in my rooms?
Use the sync_client tool. It synchronizes your local state with the homeserver, retrieving all new events, messages, and room state changes since your last sync.
Can I search for people on other Matrix servers?
Yes, the search_user_directory tool allows you to search the directory available to your homeserver, helping you find users by their display name or Matrix ID.
Is it possible to manage room settings like the topic or name?
Absolutely. Use set_room_state to update room metadata. You can change the room name, topic, or other state events by providing the correct event_type and body.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
