{
   "mcpServers": {
      "notifier": {
         "command": "npx",
         "args": [
            "-y",
            "mcp-server-notifier"
         ],
         "env": {
            "WEBHOOK_URL": "https://ntfy.sh/webhook-url-example",
            "WEBHOOK_TYPE": "ntfy"
         }
      }
   }
}

Configuration

By default, the notifier supports several webhook types:

• Discord
• Slack
• Microsoft Teams
• Feishu
• Ntfy
• Generic JSON

You can specify the webhook type and URL through environment variables:

env WEBHOOK_URL="https://your-webhook-url" WEBHOOK_TYPE="discord" npx -y mcp-server-notifier

Configuration File

For more advanced configuration, you can create a webhook-config.json file:

{
  "webhook": {
    "type": "discord",
    "url": "https://discord.com/api/webhooks/your-webhook-url",
    "name": "My Notifier"
  },
  "imgur": {
    "clientId": "your-imgur-client-id"
  }
}

See the Configuration Guide for full details and examples.

Usage

• Ask your AI agent to notify you with a custom message when a task is complete
• Configure it as a persistent rule in Cursor settings to avoid repeating the setup

For detailed usage instructions, see the Usage Guide.
