How to Use the Matrix/Element MCP in Cursor

Q: Can I use Matrix/Element to send build alerts from Cursor?

Yes, you can configure Cursor to call sendmessage whenever a build succeeds or fails. The agent formats the notification and posts it to your Matrix/Element room instantly.

Q: How do I configure the Matrix/Element MCP Server in Cursor?

Add the server details to your project-level .cursor/mcp.json file. Cursor will automatically detect the 19 MCP tools, enabling your agent to manage rooms and send messages.

Q: Does Cursor support Matrix/Element user directory searches?

Yes, the searchuserdirectory tool lets your agent find users across the homeserver. You can search for colleagues and invite them directly from the Cursor chat panel.

Q: How does the agent handle account authentication?

The server uses loginaccount and logoutaccount to manage active sessions. You run these tools once to authenticate Cursor with your homeserver credentials.

Write code that interacts with Matrix/Element rooms directly inside Cursor using live room states and messaging tools.

Automate room administration within Cursor Agent

The `create_room` tool builds new communication channels directly from your Cursor agent workspace. You can script room setups, define aliases, and set initial configurations without leaving your active code files. If access rules change, `set_room_state` updates room configurations while `get_room_state` reads current parameters. Cursor uses these tools to verify room states before generating code that relies on specific permissions.

Send automated notifications and media from Cursor

The `send_message` tool posts build alerts, code snippets, or status updates directly to your Matrix rooms. Cursor passes raw text or custom events straight to the homeserver API. To share assets like logs or screenshots, `upload_media` handles the file transfer to the homeserver. The agent then gets an MXC URI, allowing your Cursor code to reference the media in subsequent messages.

Synchronize client state using this MCP Server

The `sync_client` tool pulls the latest message timelines and events to keep Cursor updated on room activity. This MCP Server ensures your coding agent works with live data rather than stale, hardcoded mock responses. If a user is not yet in a room, the agent executes `join_room` or `knock_room` to establish the connection. This lets your Cursor workflow adapt dynamically to real-time chat environments.

Setup guide

Set up Matrix/Element MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Matrix/Element MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Matrix/Element transactions." If the MCP tools are loaded correctly, Cursor will call the Matrix/Element tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "matrixelement-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
