MCP Server Skeleton

from mcp.server import Server
from mcp.server.stdio import stdio_server

server = Server("my-server")

@server.list_tools()
async def list_tools():
    return [{"name": "my_tool", ...}]

@server.call_tool()
async def call_tool(name, arguments):
    return {"result": "..."}

async def main():
    async with stdio_server() as (read, write):
        await server.run(read, write)
