Implementation Reference
- MCP tool handler: validates API identifier, fetches API info from explorer, formats display, and returns text content or error.
async def handle_call(self, arguments: Dict[str, Any]) -> List[TextContent]: try: self._validate_api_identifier(arguments["api"]) info = await self.explorer.get_api_info(arguments["api"]) result = info.format_display() return self._create_text_response(result) except Exception as e: return self._create_error_response(e) - Defines the tool schema including name, description, and input schema for API identifier.
def get_tool_definition(self) -> Tool: return Tool( name=self.name, description=self.description, inputSchema=self.create_api_input_schema(), ) - openapi_mcp_proxy/services/tool_registry.py:37-56 (registration)Registers GetApiInfoTool by instantiating it with config_manager and explorer, adding to tools dict.
def _register_tools(self) -> None: """Register all available tools.""" tools = [ # API Management Tools AddApiTool(self.config_manager), ListSavedApisTool(self.config_manager), RemoveApiTool(self.config_manager), # API Exploration Tools GetApiInfoTool(self.config_manager, self.explorer), ListEndpointsTool(self.config_manager, self.explorer), SearchEndpointsTool(self.config_manager, self.explorer), GetEndpointDetailsTool(self.config_manager, self.explorer), ListModelsTool(self.config_manager, self.explorer), GetModelSchemaTool(self.config_manager, self.explorer), ] for tool in tools: self._tools[tool.name] = tool logger.debug(f"Registered tool: {tool.name}") - Helper method that retrieves OpenAPI schema, extracts info like title, version, description, base_url, tags into ApiInfo object.
