ntfy MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to send push notifications through ntfy.sh. This server provides a simple way to integrate real-time notifications into your AI workflows, allowing you to receive alerts on your phone, desktop, or any device that supports ntfy.sh.

What is ntfy.sh?

ntfy.sh is a simple HTTP-based pub-sub notification service that allows you to send push notifications to your devices. It's particularly useful for:

• Getting notified when long-running tasks complete
• Receiving alerts from automated workflows
• Staying informed about important events in your applications

Features

• Send messages to any ntfy.sh channel
• Support for message titles, priorities (1-5), and tags
• Simple integration with MCP-compatible AI assistants
• No authentication required for public channels

Installation

1. Install dependencies:

npm install --save-dev typescript @types/node ts-node

2. Build the TypeScript code:

npm run build

3. The MCP server is now available at ./build/index.js

Usage

Running the Server

After building, you can run the server directly:

npm start

Or point your MCP client to the built server at ./build/index.js.

Available Tools

The server provides one tool:

send_message

Sends a message to a specified ntfy.sh channel.

Parameters:

• channel (required): The ntfy.sh channel name to send the message to
• message (required): The message content to send
• title (optional): A title for the notification
• priority (optional): Priority level from 1-5 (5 being highest priority)
• tags (optional): Array of tags to categorize the message

Example usage in an MCP client:

{
  "tool": "send_message",
  "arguments": {
    "channel": "my-notifications",
    "message": "Task completed successfully!",
    "title": "Workflow Update",
    "priority": 4,
    "tags": ["automation", "success"]
  }
}

Configuration

No additional configuration is required. The server uses the public ntfy.sh service at https://ntfy.sh/.

Channel Names

• Channel names can be any string, but should be unique to avoid conflicts
• Consider using descriptive names like my-project-alerts or personal-notifications
• Anyone who knows your channel name can send messages to it, so choose wisely
