Discord MCP Server is a Model Context Protocol (MCP) server that enables large language models (LLMs) to interact with Discord channels via a bot and Discord's API. It lets LLMs read recent messages for context and send messages to specified channels. The server supports automatic discovery of servers and channels accessible by the bot and accepts channel references by name or ID. Prerequisites include Node.js 16.x or higher, a Discord bot token, and inviting the bot to servers with Read Messages/View Channels, Send Messages, and Read Message History permissions. To set up, clone the repo, install dependencies, create a .env with the DISCORD_TOKEN, and build the server. Tools available include send-message and read-messages for interacting with channels. The server is designed to work with Claude for Desktop via a configuration that runs the built index with the token provided as an environment variable. Security notes emphasize explicit user approval before sending messages and protecting tokens and permissions.
