Implementation Reference
- mcp_server_bwt/tools/bing_webmaster.py:201-203 (registration)Registers the MCP tool 'get_active_page_preview_blocks' by creating a wrapped version of the ContentBlockingService.get_active_page_preview_blocks method using wrap_service_method.
get_active_page_preview_blocks = wrap_service_method( # noqa: F841 mcp, service, "blocking", "get_active_page_preview_blocks" ) - The handler logic for the tool: an async wrapper function decorated with @mcp.tool() that manages the service context, invokes the underlying blocking service's get_active_page_preview_blocks method, and preserves the original signature and docstring.
# Create wrapper function with same signature @mcp.tool() @wraps(original_method) async def wrapper(*args: Any, **kwargs: Any) -> Any: # Filter out any 'self' arguments that might be passed by the MCP client kwargs = {k: v for k, v in kwargs.items() if k != "self"} async with service as s: service_obj = getattr(s, service_attr) # Get the method from the instance method = getattr(service_obj, method_name) # Call the method directly - it's already bound to the instance return await method(*args, **kwargs) # Copy signature and docstring wrapper.__signature__ = new_sig # type: ignore wrapper.__doc__ = original_method.__doc__ - Initializes the 'blocking' service attribute on BingWebmasterService, which provides the ContentBlockingService instance containing the get_active_page_preview_blocks method.
self.blocking = content_blocking.ContentBlockingService(self.client) - Helper function that generates the MCP tool handler by inspecting the service method signature, creating a wrapper, and registering it as an MCP tool.
