neuron

A Discord MCP server that gives AI agents full control of a Discord bot — messages, channels, roles, threads, forums, events, webhooks, reactions, moderation, image generation, and real-time voice.

Built with Bun, discord.js, and the MCP TypeScript SDK.

Features

• Messaging — send, edit, delete, pin, bulk-delete, fetch history, wait for new events in real time
• Channels & threads — create/edit/delete channels, threads, and forum posts
• Server management — roles, members, invites, webhooks, scheduled events, moderation (kick/ban/timeout)
• Voice — join voice channels, speak with ElevenLabs TTS, or run a full conversational voice agent that listens and replies
• Images — generate images with OpenAI and post them straight to a channel
• Event streaming — discord_wait_for_events blocks until new messages/reactions/etc. arrive, so an agent can run a continuous listen-and-respond loop

Setup

1. Create a bot in the Discord Developer Portal, enable the Message Content, Server Members, and Presence privileged intents as needed, and invite it to your server.

2. Install dependencies:

   bun install

3. Configure credentials:

   cp .env.example .env
   # then fill in DISCORD_BOT_TOKEN (required) and the optional keys

   Variable	Required	Purpose
   DISCORD_BOT_TOKEN	yes	Bot token for the Discord API
   ELEVENLABS_API_KEY	for voice	TTS and the conversational voice agent
   ELEVENLABS_VOICE_ID	no	Voice to speak with (has a default)
   OPENAI_API_KEY	for images	discord_generate_image
   IMAGE_OUTPUT_DIR	no	Where to save generated images

Usage

The server speaks MCP over stdio. Point any MCP client at it — for example, with Claude Code:

claude mcp add discord -- bun run /path/to/neuron/src/index.ts

Or in an mcpServers config:

{
  "mcpServers": {
    "discord": {
      "command": "bun",
      "args": ["run", "/path/to/neuron/src/index.ts"]
    }
  }
}

You can also run it directly to check that it starts:

bun start
