This MCP server exposes 7 tools for registering and managing Web APIs dynamically. However, there are critical issues across naming clarity, parameter descriptions, and output schema documentation. The tool names are somewhat descriptive but several lack the verb-first pattern recommended for LLM clarity. Many parameters have type definitions but lack adequate descriptions explaining their purpose in the context of API registration. Output schemas are not explicitly documented, responses are inferred from code execution patterns rather than declared. The server does have a multi-tool composition pattern (register API, then invoke it) but this is not well-integrated into the tool definitions themselves. Descriptions vary in quality: some are translated from Chinese and are moderately detailed (register_web_api, set_default_headers), while others are sparse (load_api_from_file, load_apis_from_directory). Error handling is present in the code but not reflected in tool descriptions, so LLMs cannot anticipate failure modes or recovery steps.

• Add explicit output schema documentation to all tools. For register_web_api, specify: { 'success': boolean, 'apiName': string, 'createdToolCount': number, 'toolNames': string[] }. For list_registered_apis, specify: { 'apis': [{ 'name': string, 'url': string, 'method': enum, 'parameters': object, ... }], 'totalCount': number }.
• Expand descriptions for load_api_from_file, load_apis_from_directory, and load_from_config. Add expected file format (JSON structure for APIs, YAML structure for config), any file encoding assumptions, and whether the tool appends or overwrites existing registrations.
• Add parameter descriptions for 'parameters' (in register_web_api) and 'pattern' (in load_apis_from_directory). Provide examples: 'parameters is a map where keys are param names and values are { type: "string"|"number"|"boolean"|"object"|"array", required: boolean, description: string }' and 'pattern is a glob pattern like *.json or api-*.yaml'.
• Document error cases and recovery guidance in all tool descriptions. E.g., for register_web_api: 'If the API URL is unreachable, the tool will fail validation. Verify the URL is correct and accessible. If API parameters are malformed, call list_registered_apis to see already-registered APIs and compare structure.' This guides LLM error handling.
• Add a dependency note to register_web_api: 'After registering an API, call list_registered_apis to confirm it was added, then use the newly created tool (with the API name) to invoke the API.' This makes the workflow explicit.
