THEN Ensure the server implementation registers all required handlers using the MCP SDK's decorators or functions. For example, call `server.tool()` for each tool, `server.resource()` for each resource, and `server.prompt()` for each prompt before starting the server. Missing registration causes the server to respond with -32601 error.

from mcp.server import Server

app = Server("my-server")

@app.tool()
async def my_tool(arg: str) -> str:
    return f"Processed {arg}"

@app.resource("data://{path}")
async def get_resource(path: str) -> str:
    return f"Data for {path}"

# Start the server
app.run()
