ntfy-me-mcp

A streamlined Model Context Protocol (MCP) server for sending notifications via ntfy service (public or selfhosted with token support) 📲

Overview

ntfy-me-mcp provides AI assistants with the ability to send real-time notifications to your devices through the ntfy.sh service (either public or selfhosted with token support). Get notified when your AI completes tasks, encounters errors, or reaches important milestones - all without constant monitoring.

Quickstart - MCP Server Configuration

Choose the config shape that matches your client. All examples below use NTFY_TOPIC as the required variable and keep the optional auth settings commented out until you need them.

Configuration Examples

Installation

If you need to install and run the server directly (alternative to the MCP configuration above):

Setting Up the Notification Receiver

1. Install the ntfy app on your device

   • or deploy your own ntfy server: https://docs.ntfy.sh/install/

2. Subscribe to your chosen topic (the same as your NTFY_TOPIC setting)

Configuration

Environment Variables

Create a .env file by copying the example: cp .env.example .env — see .env.example for reference.

Authentication

This MCP server supports both authenticated and unauthenticated ntfy endpoints:

• Public Topics: When using public topics on ntfy.sh or other public servers, no authentication is required.

• Protected Topics:

  • For protected topics or private servers, you need to provide an access token via NTFY_TOKEN env variable or in the accessToken parameter of the tool.

  • If authentication is required but not provided, you'll receive a clear error message explaining how to add your token.

Secure Token Handling (vscode)

• If your client supports prompt-based secret inputs (i.e. VS Code), prefer that over hardcoding NTFY_TOKEN in config files. (Otherwise use your token directly)

• Use matching values like this in your mcp.json file:

// Add this to your VS Code `mcp.json` file, either the user-level file or your workspace `.vscode/mcp.json`
// Set `NTFY_TOKEN` exactly to `"${input:ntfy_token}"` when you want VS Code to treat it as a secure prompt-backed value.

{
  "inputs": [
    {
      "type": "promptString",
      "id": "ntfy_token",
      "description": "Ntfy Token",
      "password": true
    }
  ],
  "servers": {
    "ntfy-me-mcp": {
      "command": "npx",
      "args": ["-y", "ntfy-me-mcp"],
      "env": {
        "NTFY_TOPIC": "your-ntfy-topic",
        "NTFY_URL": "https://your-ntfy-server.com",
        "NTFY_TOKEN": "${input:ntfy_token}"
      }
    }
  }
}

If the client resolves "${input:ntfy_token}" before launch, the server receives the real token directly. If the placeholder is passed through unchanged, ntfy-me-mcp detects that unresolved input reference and prompts for the token itself at startup.

Since v1.4.0+, the PROTECTED_TOPIC env has been removed. This handling is now auto-detected from the unresolved NTFY_TOKEN input reference instead.
