MCP System Tools Server

This is a production-ready Model Context Protocol (MCP) server built in Python. It provides custom tools that AI Agents (like Claude or custom LangChain/LlamaIndex bots) can connect to and use to interact with the host system.

🛠️ Included Tools

1. get_system_stats: Retrieves current live system statistics (CPU usage, Memory usage, Available Memory).
2. calculate_expression: A safe math evaluator that performs basic arithmetic operations.

🚀 How to Run (Docker - Recommended)

If you have Docker installed, you can spin up the entire isolated environment with one command:

docker-compose up --build -d

The Server-Sent Events (SSE) endpoint will be available at: http://localhost:8000/sse

💻 How to Run (Local Python)

If you don't have Docker, you can run the server directly using Python.

1. Install the requirements:

pip install -r requirements.txt

2. Run the server:

python mcp_server.py

The server will boot up and listen for connections on http://127.0.0.1:8000/sse.

🧪 Testing the Server

You can quickly test your tools using the official MCP Inspector. Run the following command in a new terminal:

npx -y @modelcontextprotocol/inspector

• Select SSE as the transport.
• Enter http://127.0.0.1:8000/sse as the URL and click Connect.

Alternatively, run the included test_client.py script:

python test_client.py

🤖 Connecting to Claude Desktop

You can easily give Claude Desktop the ability to use these tools. Add this configuration to your Claude config file (claude_desktop_config.json):

{
  "mcpServers": {
    "system-tools": {
      "command": "python",
      "args": [
        "path/to/your/mcp_server.py"
      ]
    }
  }
}
