from fastmcp import FastMCP
mcp = FastMCP(name="First Mcp")


@mcp.tool
def add(a: int, b: int) -> int:
    """
    Adds two integer numbers togather
    :param a:
    :param b:
    :return:
    """
    return  a + b

@mcp.resource("resource://config")
def get_config() -> dict:
    """Provides the application's configuration"""
    return {"version": "1.0", "author": "Myteam"}


if __name__ == "__main__":
    mcp.run()

4、debug测试

fastmcp dev server.py
