discord-mcp

Discord selfbot MCP server — read & send Discord messages from Claude Code or OpenClaw.

⚠️ Selfbot Warning: This uses your Discord user token, which violates Discord's ToS. Your account may be banned. Use at your own risk.

What it does

Exposes 6 Discord tools via MCP (Model Context Protocol):

A background daemon maintains a persistent WebSocket to the Discord Gateway, ingesting messages into a local SQLite database so discord_get_unread works even while Claude isn't running.

Setup

1. Install & configure

npx @tensakulabs/discord-mcp setup

This will:

1. Show you how to extract your Discord token from the desktop app
2. Save it securely to your OS keychain (macOS: uses built-in security CLI — no native module required)
3. Start the background daemon via launchd (macOS) or systemd (Linux)
4. Auto-register the MCP server in Claude's config

2. Token extraction (step shown during setup)

Open Discord desktop app → Press Ctrl+Shift+I (or Cmd+Option+I on Mac) → Network tab → Send any message in Discord → filter requests by messages → click any request → Headers tab → find the Authorization header → copy its value.

3. Restart Claude

Restart Claude Code. You'll see Discord tools available.

Verify it's working

npx @tensakulabs/discord-mcp status
# ✅ Connected as: yourname#0

Manual MCP config (if auto-config fails)

Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "discord": {
      "command": "npx",
      "args": ["-y", "@tensakulabs/discord-mcp"]
    }
  }
}

Usage with Claude

Once registered, Claude can use Discord tools directly:

"What did I miss in the #general channel of the Tensaku server?"
→ Claude calls discord_list_guilds, discord_list_channels, discord_get_unread

"Reply to Alex saying I'll be there at 5pm"
→ Claude calls discord_send_message with replyToMessageId

Hooks

Fire shell commands or HTTP webhooks when Discord events occur. Configure in ~/.config/discord-mcp/config.json:

{
  "hooks": {
    "on_mention": [
      {
        "type": "command",
        "enabled": true,
        "command": "osascript -e 'display notification \"{content}\" with title \"Mention from {author}\"'"
      }
    ],
    "on_everyone": [],
    "on_here": [],
    "on_message": []
  }
}

Hook types

Hook config fields

Template variables

Available in command strings and HTTP POST body:

HTTP hook payload

{
  "author": "username",
  "content": "message text",
  "channel": "channel-id",
  "guild": "guild-id",
  "is_dm": false
}

OpenClaw integration

Add to OpenClaw's MCP config:

{
  "mcp": {
    "servers": [{
      "name": "discord",
      "transport": "stdio",
      "command": "npx",
      "args": ["-y", "@tensakulabs/discord-mcp"]
    }]
  }
}

Security

• Token stored in OS keychain (macOS: security CLI — no native module compilation needed; Linux: keytar; fallback: AES-256-CBC encrypted file)
• Token never written to config files or logs
• Local files at ~/.config/discord-mcp/: messages.db, config.json, token.enc (fallback only), daemon.log

All Discord API calls go through rateLimitedFetch — automatic backoff on 429.

The daemon runs as a launchd service (com.discord-mcp.daemon) on macOS, connecting to wss://gateway.discord.gg and storing all messages locally for fast unread queries.
