Tools Reference

discord_ask

Send a question and wait for user response. Supports reaction-based interactions.

Reactions automatically added:

• 📷 Take screenshot
• ❌ Cancel request

Response format:

{
  "text": "User's response text",
  "attachments": [{ "filename": "...", "url": "..." }],
  "cancelled": false
}

discord_notify

Send a notification (no response expected).

discord_send_file

Send a file to the user.

discord_screenshot

Take and send a desktop screenshot.

Requires pip install discord-mcp-agent[screenshot]

discord_embed

Send a rich embed message with full formatting.

Reaction Features

Every message from the bot includes interactive reaction buttons:

How It Works

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

Configuration

Environment Variables

Custom Reminder

Inject custom instructions into every tool response:

{
  "env": {
    "DISCORD_REMINDER": "Remember: Always confirm with the user before completing tasks."
  }
}

Adjust timeouts for your use case:

{
  "env": {
    "DISCORD_ASK_TIMEOUT": "600",

Usage Examples

MCP Tool Call: Ask Question

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

Response:

    ],
    "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

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
