Add your Discord bot to your server
- To add your Discord bot to your server, use one of the following invite links (replace INSERT_CLIENT_ID_HERE with your bot's client ID):
  - Administrator (full access): https://discord.com/oauth2/authorize?client_id=INSERT_CLIENT_ID_HERE&scope=bot&permissions=8
  - Custom permissions (minimum required): https://discord.com/oauth2/authorize?client_id=INSERT_CLIENT_ID_HERE&scope=bot&permissions=52076489808

Note:
According to Discord's security model, a bot can only access information from servers it has been explicitly added to.
If you want to use this MCP server to access a specific Discord server, you must add the bot to that server first.
Use the invite link below to add the bot to your target server.

Installation

Installing via NPM

You can use it with the following command:

npx mcp-discord --config ${DISCORD_TOKEN}

For more details, you can check out the NPM Package.

Manual Installation

# Clone the repository
git clone https://github.com/IQAICOM/mcp-discord.git
cd mcp-discord

# Install dependencies
npm install

# Compile TypeScript
npm run build

Configuration

All configuration is now handled via the src/config.ts file, which supports both environment variables and command-line arguments. The following options are available:

| Option | Type | Default | Description | |-------------------------------|----------|-----------|-----------------------------------------------------------------------------| | DISCORD_TOKEN | string | — | Required. Discord bot token. | | SAMPLING_ENABLED | boolean | true | Enables bi-directional message sampling (see Sampling). | | TRANSPORT | string | stdio | Transport method: stdio (default) or http. | | HTTP_PORT | number | 8080 | Port for HTTP transport (only if TRANSPORT is http). | | DEFAULT_RATE_LIMIT_SECONDS | number | 2 | Rate limit (seconds) for sampling requests per user. | | DEFAULT_MESSAGE_CHUNK_SIZE | number | 2000 | Max message chunk size for sampling responses. |

You can set these options via environment variables or command-line arguments:

Environment variables:

DISCORD_TOKEN=your_discord_bot_token
SAMPLING_ENABLED=false
TRANSPORT=http
HTTP_PORT=3000
DEFAULT_RATE_LIMIT_SECONDS=5
DEFAULT_MESSAGE_CHUNK_SIZE=1500

Command-line arguments:

node build/index.js --config "your_discord_bot_token" --sampling --transport http --port 3000 --rate-limit 5 --message-chunk-size 1500

If both are provided, command-line arguments take precedence.

Sampling

The Sampling feature enables bi-directional communication between Discord and the MCP server, allowing the bot to listen to messages and respond automatically. This is controlled by the SAMPLING_ENABLED config option (enabled by default).

How it works:

When enabled, the bot listens for new messages and bot mentions in Discord channels.
If a user sends a message, the bot can process it and respond using the MCP protocol.
The bot adds a 🤔 reaction when mentioned.
Rate limiting is enforced per user (see DEFAULT_RATE_LIMIT_SECONDS).
Long responses are split into chunks (see DEFAULT_MESSAGE_CHUNK_SIZE).

Disabling Sampling:

Set SAMPLING_ENABLED=false in your environment or omit the --sampling flag.
The bot will not listen to or respond to messages automatically.

Advanced options:

DEFAULT_RATE_LIMIT_SECONDS: Minimum seconds between sampling responses per user.
DEFAULT_MESSAGE_CHUNK_SIZE: Maximum size of each message chunk sent in response.
