4. Configure MCP Settings

The server requires configuration in your MCP settings file. Add the following to your configuration file:

{
    "mcpServers": {
        "discord-relay": {
            "command": "node",
            "args": [
                "/ABSOLUTE/PATH/TO/MCP Relay/build/index.js"
            ],
            "env": {
                "DISCORD_TOKEN": "your_bot_token_here",
                "DISCORD_CHANNEL_ID": "your_channel_id_here"
            }
        }
    }
}

Replace:

• /ABSOLUTE/PATH/TO/MCP Relay with the actual path to your MCP Relay project
• your_bot_token_here with your Discord bot token
• your_channel_id_here with your Discord channel ID

Note: Make sure to use absolute paths in the configuration.

Usage

The server provides a tool called send-message that accepts the following parameters:

{
  type: 'prompt' | 'notification',  // Type of message
  title: string,                    // Message title
  content: string,                  // Message content
  actions?: Array<{                 // Optional action buttons
    label: string,                  // Button label
    value: string                   // Value returned when clicked
  }>,
  timeout?: number                  // Optional timeout in milliseconds
}

Message Types

1. Notification: Simple message that doesn’t expect a response

   {
     "type": "notification",
     "title": "Hello",
     "content": "This is a notification"
   }

2. Prompt: Message that waits for a response

   {
     "type": "prompt",
     "title": "Question",
     "content": "Do you want to proceed?",
     "actions": [
       { "label": "Yes", "value": "yes" },
       { "label": "No", "value": "no" }
     ],
     "timeout": 60000  // Optional: 1 minute timeout
   }

Notes:

• Prompts can be answered either by clicking action buttons or sending a text message
• Only one response is accepted per prompt
• If a timeout is specified, the prompt will fail after the timeout period
• Notifications don’t wait for responses and return immediately
