   • ✅ Message Content Intent
6. Go to OAuth2 → URL Generator:
   • Scopes: bot
   • Bot Permissions: Send Messages, Read Message History, Add Reactions, Attach Files
7. Copy the generated URL and open it to invite the bot to your server
8. Get your Server ID: Enable Developer Mode in Discord settings, right-click your server → Copy ID

⏳	Timeout	Added automatically when a request times out

2. User can click reactions to trigger actions
3. 📷 immediately captures and sends a screenshot
4. ❌ cancels waiting and returns "cancelled": true

Usage Examples

MCP Tool Call: Ask Question

{
  "name": "discord_ask",
  "arguments": {
    "question": "What color theme would you like for the dashboard?"
  }
}

Response:

{
  "text": "I'd prefer a dark theme with blue accents",
  "attachments": [],
  "cancelled": false
}

MCP Tool Call: Send Embed

{
  "name": "discord_embed",
  "arguments": {
    "title": "Build Complete ✅",
    "description": "Your project has been successfully built.",
    "color": 5763719,
    "fields": [
      { "name": "Duration", "value": "2m 34s", "inline": true },
      { "name": "Size", "value": "1.2 MB", "inline": true }
    ],
    "footer": "Built with discord-mcp-agent"
  }
}

Handling Image Attachments

When users send images in response to discord_ask, they're automatically:

1. Downloaded from Discord
2. Encoded as base64
3. Returned as ImageContent for AI model consumption

Troubleshooting

Error	Cause	Solution
DISCORD_TOKEN environment variable is required	Missing token	Set DISCORD_TOKEN in your MCP config
Guild with ID X not found	Bot not in server	Invite bot using OAuth2 URL
Channel 'X' not found in guild	Wrong channel name	Check DISCORD_CHANNEL matches exactly
Failed to connect within 30 seconds	Network/token issue	Verify token and network connectivity
PIL not installed	Screenshot dep missing	Run pip install discord-mcp-agent[screenshot]
⏳ No response received within X seconds	User didn't respond	Increase DISCORD_ASK_TIMEOUT or user can click ❌

Common Issues

Bot appears offline:

• Ensure Message Content Intent is enabled in Discord Developer Portal
• Check that the bot token is correct

Bot can't see messages:

• Enable Message Content Intent in bot settings
• Ensure bot has Read Message History permission

Screenshots not working:

• Install Pillow: pip install discord-mcp-agent[screenshot]
• On Linux, may require display server access

Requirements

• Python 3.10+
• mcp >= 1.0.0
• discord.py >= 2.0.0
• pydantic >= 2.0.0
• aiohttp >= 3.8.0
• Pillow >= 10.0.0 (optional, for screenshots)

Security

⚠️ Never commit your Discord bot token to version control!

• Use environment variables or .env files
• Add .env to .gitignore
• Regenerate token immediately if exposed
