What is the MCP Relay MCP server?

Mcp relay mcp server lets Claude, Cursor and other MCP clients work with MCP Relay directly. Discord relay MCP server.

What MCP Relay does

This MCP server allows Claude to send messages and prompts to a Discord channel and receive responses.

Installing the mcp relay mcp server

Setup follows the standard MCP pattern: clone or install the server, then register it in your client's configuration file and restart the client. The configuration snippets on this page cover Claude Desktop, Claude Code and Cursor.

Configuration

Before the server will start you need to supply 2 environment variables: DISCORD_TOKEN, DISCORD_CHANNEL_ID. Keep credentials in your client's env block or a secrets manager rather than committing them.

Where it fits

Communication servers earn their keep on volume — summarising channels and threads that would otherwise cost you an hour of scrollback. MCP Relay sits in that group. Worth comparing against the other communication servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • It will not start until its required credentials are present, so set those before wondering why the tools never appear.
  • Maintained by emiliobool, written in TypeScript.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the mcp relay mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.
