Three tools with visible schemas and descriptions, but significant quality gaps. Tool naming lacks action verbs (initialize, tools_list, tools_call are generic/vague). Descriptions are present but brief (10-50 chars), below the 50-200 char LLM-optimized baseline. Parameter descriptions exist but lack detail on constraints, formats, and valid ranges. The 'arguments' parameter in tools_call is a free-form object with no schema, LLMs cannot infer what keys/types are valid. No output schemas documented. Error handling is absent from tool definitions. Security concern: auth_token exposed as a parameter rather than server-side injection.

• Rename tools with action verbs: 'configure_openapi_server', 'list_available_tools', 'execute_tool'. This helps LLMs parse intent from the name alone.
• Expand descriptions to 50-200 chars. Example for tools_call: 'Execute a registered OpenAPI tool by name with arguments. Returns the API response or error details. Use after calling list_available_tools to discover tool names.'
• For tools_call, replace free-form 'arguments' object with a structured schema. Either: (a) accept a JSON string parameter with validation, or (b) dynamically generate tool definitions per OpenAPI operation with explicit parameters.
• Move auth_token to server-side configuration (environment variable or config file). Remove it from the initialize tool parameters. Document how to set it in the README.
• Document output schemas for each tool. Example: tools_list returns {tools: [{name, description, inputSchema, tags}]}. tools_call returns {result: <API response>, status_code, headers}.
