devctl-mcp 0.0.1

A basic MCP (Model Context Protocol) server implementation

DevCtl MCP

A Model Context Protocol (MCP) server for managing development processes. Start, stop, and monitor your development servers, background tasks, and other processes directly through Claude or other MCP-compatible clients.

Features

• 🚀 Start/Stop Processes: Launch and terminate development processes by name
• 📊 Process Monitoring: View real-time status and uptime for all processes
• 📝 Log Management: Retrieve and view process logs with configurable line limits
• ⚙️ YAML Configuration: Define processes with commands, arguments, working directories, and environment variables
• 🔄 Automatic Cleanup: Graceful shutdown of all processes when the server terminates
• 🛡️ Process Groups: Proper signal handling for clean process termination

Installation

pip install devctl-mcp

Configuration

Create a processes.yaml file in your project root to define your development processes:

processes:
  # Example Go API server
  go_api:
    cmd: go
    args:
      - run
      - ./cmd/server
    working_directory: ~/projects/my-api
    env:
      PORT: "8080"
      GO_ENV: "development"
  
  # Example Python web server
  web_server:
    cmd: python
    args:
      - -m
      - flask
      - run
    working_directory: /path/to/your/flask/project
    env:
      FLASK_APP: app.py
      FLASK_ENV: development
      FLASK_DEBUG: "1"
  
  # Example Node.js development server
  frontend:
    cmd: npm
    args:
      - run
      - dev
    working_directory: /path/to/your/frontend
    env:
      NODE_ENV: development

MCP Client Setup

{
  "mcpServers": {
    "devctl": {
      "command": "devctl-mcp"
    }
  }
}

Parameters:

• name (required): The name of the process to start

stop_process

Stop a running process.

Parameters:

• name (required): The name of the process to stop
• force (optional): Force kill the process (default: false)
