Discord MCP Server

An MCP server that exposes Discord admin operations as tools. Built with TypeScript + Bun, using direct Discord REST API v10 calls (no discord.js dependency).

Features

33 tools for Discord server administration
Channel management, role management, member moderation, server configuration
Composite tools for common multi-step workflows (category setup, channel lockdown, bulk role assignment)
Built-in rate limiting with per-route bucket tracking and automatic retry
Audit log reasons for all write operations via X-Audit-Log-Reason header

Prerequisites

Bun v1.0+
A Discord bot token with appropriate permissions

Discord Bot Setup

Go to https://discord.com/developers/applications
Create a new application
Go to the Bot tab, create a bot, and copy the token
Enable required intents: Server Members Intent (needed for member listing)
Go to OAuth2 > URL Generator
Select scopes: bot
Select permissions: Administrator (or granular permissions: Manage Channels, Manage Roles, Kick Members, Ban Members, Manage Guild, Moderate Members)
Copy the generated invite URL and add the bot to your server
Copy the Guild ID (right-click the server name in Discord > Copy Server ID -- requires Developer Mode enabled in Discord settings)
