ai-mcp

Lightweight MCP server for agent, register tools.

Overview

This project creates minimal MCP services that expose small tools (examples: system info, weather lookup) and run them via standard input/output. It is intended as a reference for wiring functions into MCP FastMCP instances.

Files

  • system_information_mcp.py — implement system information MCP and register tool get_system_info.
  • weather_mcp.py — implement weather MCP and register tools to get weather info using the U.S. National Weather Service API.
  • pyproject.toml — project metadata and dependencies.
  • .python-version — recommended Python version (3.12).

Requirements

  • Python 3.12
  • Recommended: use a virtual environment

Configuration agent

Configure MCP server in Cline

 "system information mcp": {
      "disabled": false,
      "timeout": 60,
      "type": "stdio",
      "command": "uv",
      "args": [
        "--directory",
        "D:/YJWANG/workspace/code/ai/ai-mcp",
        "run",
        "system_information_mcp.py"
      ]
    },
    "weather mcp": {
      "disabled": false,
      "timeout": 60,
      "type": "stdio",
      "command": "uv",
      "args": [
        "--directory",
        "D:/YJWANG/workspace/code/ai/ai-mcp",
        "run",
        "weather_mcp.py"
      ]
    }

You should change the path according to your envrionment.

Run

  • System info MCP:
uv run system_information_mcp.py
  • Weather MCP (weather_mcp.py):
uv run weather_mcp.py

Each script creates a FastMCP instance, registers one or more tools, and runs in stdio mode. Use your MCP-compatible client or protocol over stdio to call the registered tools.

Then, you can ask questions in agent, such as Cline
