MCP server for Dead Man's Snitch monitoring service

MCP Dead Man's Snitch

A Model Context Protocol (MCP) server for Dead Man's Snitch monitoring service. This server enables AI assistants like Claude to interact with Dead Man's Snitch to monitor scheduled tasks and cron jobs.

What it does

This MCP server provides tools to:

• List and search your monitoring snitches
• Check in (ping) snitches to confirm tasks are running
• Create new monitors for your scheduled jobs
• Update, pause, or delete existing monitors
• Manage tags for organizing your snitches

Installation & Setup

1. Get your API key from Dead Man's Snitch account settings

2. Configure your MCP client by adding this to your settings:

{
  "mcpServers": {
    "deadmansnitch": {
      "command": "uvx",
      "args": ["mcp-deadmansnitch"],
      "env": {
        "DEADMANSNITCH_API_KEY": "your_api_key_here"
      }
    }
  }
}

For Nix users, this project provides a flake with packages, overlays, and a development shell:

# Run directly
nix run github:jamesbrink/mcp-deadmansnitch

# Build the package
nix build github:jamesbrink/mcp-deadmansnitch

See NIX.md for detailed NixOS configuration and declarative usage.

docker load < result

# Run the server
docker run --rm -e DEADMANSNITCH_API_KEY="your_api_key" mcp-deadmansnitch:latest

{
  "mcpServers": {
    "deadmansnitch": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "-e", "DEADMANSNITCH_API_KEY", "mcp-deadmansnitch:latest"],
