Use Low Level API and avoid code generator

[antonio-gabriele]

I think you could use low level api to avoid code generator.

from modelcontextprotocol import MCPServer, ListToolsRequest, ListToolsResponse, Tool, Metadata

# Define your generic tools with necessary metadata OR READ FROM OPEN API DEFINITION.
GENERIC_TOOLS = [
    Tool(
        id="post_resource1",
        name="Calculator",
        description="A simple calculator tool for arithmetic operations.",
        metadata=Metadata(
            version="1.0",
            author="AI Team",
            tags=["math", "arithmetic"]
        )
    ),
    Tool(
        id="post_resource2",
        name="Weather Checker",
        description="Provides current weather information for a given location.",
        metadata=Metadata(
            version="1.2",
            author="AI Team",
            tags=["weather", "information"]
        )
    ),
    Tool(
        id="get_resource1",
        name="Text Translator",
        description="Translates text between different languages.",
        metadata=Metadata(
            version="0.9",
            author="AI Team",
            tags=["language", "translation"]
        )
    ),
]

def handle_list_tools(request: ListToolsRequest, context):
    # You can use 'request' or 'context' if you want to filter tools, etc.
    return ListToolsResponse(tools=GENERIC_TOOLS)

# Create the MCP server and add the interceptor/handler
server = MCPServer()

# Register handler for ListToolsRequest
server.add_request_handler(ListToolsRequest, handle_list_tools)
# server.add_request_handler(ListToolsRequest, handle_call_tool) # TODO
# Read id and split over _ so you'll get get_resource1 -> GET /resource1
# Obviously take care of the payload and headers!!!
if __name__ == "__main__":
    print("Starting MCP Server for tool listing...")
    server.run()

Similarly you can use CallToolRequest to perform API call.
