Quickstart - MCP Server Configuration

NPM / NPX (Recommended Method)

• Requires npm / npx installed on your system.
• This method is recommended for most users as it provides a simple & lightweight method to set up the server.

For the easiest setup with MCP-compatible assistants, add this to your MCP configuration:

Minimal configuration (for public topics on ntfy.sh)

{
  "ntfy-me-mcp": {
    "command": "npx",
    "args": ["ntfy-me-mcp"],
    "env": {
      "NTFY_TOPIC": "your-topic-name"
    }
  }
}

Full configuration (for private servers or protected topics)

Option 1: Direct token in configuration

{
  "ntfy-me-mcp": {
    "command": "npx",
    "args": ["ntfy-me-mcp"],
    "env": {
      "NTFY_TOPIC": "your-topic-name",
      "NTFY_URL": "https://your-ntfy-server.com",
      "NTFY_TOKEN": "your-auth-token" // Use if using a protected topic/server
    }
  }
}

Option 2: Using VS Code inputs for secure token handling (recommended)

Add this to your VS Code settings.json file:

"mcp": {
  "inputs": [
    { // Add this to your inputs array
      "type": "promptString",
      "id": "ntfy_token",
      "description": "Ntfy Token",
      "password": true
    }
  ],
  "servers": {
    // Other servers...
    "ntfy-me-mcp": {
      "command": "npx",
      "args": ["ntfy-me-mcp"],
      "env": {
        "NTFY_TOPIC": "your-topic-name",
        "NTFY_URL": "https://your-ntfy-server.com",
        "NTFY_TOKEN": "${input:ntfy_token}", // Use the input id variable for the token
        "PROTECTED_TOPIC": "true" // Prompts for token and masks it in your config
      }
    }
  }
}

With this setup, VS Code will prompt you for the token when starting the server and the token will be masked when entered.

Docker

Using with MCP in Docker

• Requires Docker installed on your system.
• This method is useful for running the server in a containerized environment.
• You can use the official Docker images available on Docker Hub or GitHub Container Registry.

Docker Images:

• gitmotion/ntfy-me-mcp:latest (Docker Hub)
• ghcr.io/gitmotion/ntfy-me-mcp:latest (GitHub Container Registry)

In your MCP configuration (e.g., VS Code settings.json):

"mcp": {
  "servers": {
    "ntfy-mcp": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "NTFY_TOPIC",
        "-e",
        "NTFY_URL",
        "-e",
        "NTFY_TOKEN",
        "-e",
        "PROTECTED_TOPIC",
        "gitmotion/ntfy-me-mcp", // OR use ghcr.io/gitmotion/ntfy-me-mcp:latest
      ],
      "env": {
        "NTFY_TOPIC": "your-topic-name",
        "NTFY_URL": "https://your-ntfy-server.com",
        "NTFY_TOKEN": "${input:ntfy_token}",
        "PROTECTED_TOPIC": "true"
      }
    }
  }
}

Installation

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

Option 1: Install globally

npm install -g ntfy-me-mcp

Option 2: Run with npx

npx ntfy-me-mcp

Option 3: Install locally

# Clone the repository
git clone https://github.com/gitmotion/ntfy-me-mcp.git
cd ntfy-me-mcp

# Install dependencies
npm install

# Copy the example environment file and configure it
cp .env.example .env
# Edit .env with your preferred editor and update the variables
# nano .env  # or use your preferred editor

# Build the project
npm run build

# Start the server
npm start

Option 4: Build and use locally with node command

If you're developing or customizing the server, you might want to run it directly with node:

# Clone the repository
git clone https://github.com/gitmotion/ntfy-me-mcp.git
cd ntfy-me-mcp

# Install dependencies
npm install

# Copy the example environment file and configure it
cp .env.example .env
# Edit the .env file to set your NTFY_TOPIC and other optional settings
# nano .env  # or use your preferred editor

# Build the project
npm run build

# Run using node directly
npm start

Using locally built server with MCP

When configuring your MCP to use a locally built version, specify the node command and path to the built index.js file:

{
  "ntfy-me": {
    "command": "node",
    "args": ["/path/to/ntfy-mcp/build/index.js"],
    "env": {
      "NTFY_TOPIC": "your-topic-name"
      //"NTFY_URL": "https://your-ntfy-server.com", // Use if using a self-hosted server
      //"NTFY_TOKEN": "your-auth-token" // Use if using a protected topic/server
    }
  }
}

Remember to use the absolute path to your build/index.js file in the args array.

Option 5: MCP Marketplace installations

Installing via Smithery

To install ntfy-me-mcp for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @gitmotion/ntfy-me-mcp --client claude

Configuration

Environment Variables

Create a .env file in your project directory by copying the provided example:

# Copy the example file
cp .env.example .env

# Edit the file with your preferred editor
nano .env  # or vim, code, etc.

Your .env file should contain these variables:

# Required
NTFY_TOPIC=your-topic-name

# Optional - Configure these if using a private/protected ntfy server
# NTFY_URL=https://ntfy.sh  # Default is ntfy.sh, change to your self-hosted ntfy server URL if needed
                            # Include port if needed, e.g., https://your-ntfy-server.com:8443
# NTFY_TOKEN=your-access-token  # Required for authentication with protected topics/servers
# PROTECTED_TOPIC=false  # Set to "true" if your topic requires authentication (helps prevent auth errors)

Note: The PROTECTED_TOPIC flag helps the application determine whether authentication is required for your topic. When set to "true" and no token is provided, you'll be prompted to enter one. This prevents authentication failures with protected topics.

Usage

Authentication

This 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.

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

Setting Up the Notification Receiver

1. Install the ntfy app on your device
2. Subscribe to your chosen topic (the same as your NTFY_TOPIC setting)

Sending Notifications (ntfy_me tool)

This section covers all functionality related to sending notifications using the ntfy_me tool.

Using Natural Language

When working with your AI assistant, you can use natural phrases like:

"Send me a notification when the build is complete"
"Notify me when the task is done"
"Alert me after generating the code"
"Message me when the process finishes"
"Send an alert with high priority"

Message Parameters

The tool accepts these parameters:

Example:

{
  taskTitle: "Code Generation Complete",
  taskSummary: "Your React component has been created successfully with proper TypeScript typing.",
  priority: "high",
  tags: ["check", "code", "react"]
}

This will send a high-priority notification with a checkmark emoji.

Action Links

You can add clickable action buttons to your notifications using the actions parameter, or let the server automatically detect URLs in your message.

Automatic URL Detection

When URLs are present in the message body, the server automatically creates up to 3 view actions (ntfy's maximum limit) from the first detected URLs. This makes it easy to include clickable links without manually specifying the actions array.

For example, this message:

{
  taskTitle: "Build Complete",
  taskSummary: "Your PR has been merged! View the changes at https://github.com/org/repo/pull/123 or check the deployment at https://staging.app.com"
}

Will automatically generate view actions for both URLs, making them easily clickable in the notification.

Manual Action Configuration

For more control, you can manually specify actions:

Example with action links:

{
  taskTitle: "Pull Request Review",
  taskSummary: "Your code has been reviewed and is ready for final checks",
  priority: "high",
  tags: ["check", "code"],
  actions: [
    {
      action: "view",
      label: "View PR",
      url: "https://github.com/org/repo/pull/123"
    },
    {
      action: "view",
      label: "View Changes",
      url: "https://github.com/org/repo/pull/123/files",
      clear: true
    }
  ]
}

Emoji Shortcodes

You can use emoji shortcodes in your tags for visual indicators:

• warning → ⚠️
• check → ✅
• rocket → 🚀
• tada → 🎉

See the full list of supported emoji shortcodes.

Markdown Formatting

Your notifications support rich markdown formatting with intelligent detection! When you include markdown syntax in your taskSummary, the server automatically detects it and enables markdown parsing - no need to set markdown: true explicitly.

Automatic Detection

The server checks for common markdown patterns like:

• Headers (#, ##, etc.)
• Lists (-, *, numbers)
• Code blocks (```)
• Links (text)
• Bold/italic (text, text)

When these patterns are detected, markdown parsing is automatically enabled for the message.

Manual Override

While automatic detection works in most cases, you can still explicitly control markdown parsing:

{
  taskTitle: "Task Complete",
  taskSummary: "Regular plain text message",
  markdown: false  // Force disable markdown parsing
}

Retrieving Messages (ntfy_me_fetch tool)

This section covers all functionality related to fetching and filtering messages using the ntfy_me_fetch tool.

Using Natural Language

AI assistants understand various ways to request message fetching:

"Show me my recent notifications"
"Get messages from the last hour"
"Find notifications with title 'Build Complete'"
"Search for messages with the test_tube tag"
"Show notifications from the updates topic from the last 24hr"
"Check my latest alerts"

Message Parameters

The tool accepts these parameters:

Examples

1. Fetch Recent Messages

{
  since: "30m"; // Get messages from last 30 minutes
}

2. Filter by Title and Priority

{
  messageTitle: "Build Complete",
  priorities: "high",
  since: "1d"
}

3. Search Different Topic with Tags

{
  ntfyTopic: "updates",
  tags: ["error", "warning"],
  since: "all"
}

4. Find Specific Message

{
  messageId: "xxxxXXXXxxxx";
}

Messages are returned with full details including:

• Message ID and timestamp
• Topic and title
• Content and priority
• Tags and attachments
• Action links and expiration

Note: Message history availability depends on your ntfy server's cache settings. The public ntfy.sh server typically caches messages for 12 hours.
