Single tool 'dynamic_tools_from_openapi' has critical definition gaps. Input schema is declared as empty object with additionalProperties=true and a generic description stating schemas are 'dynamically generated per endpoint', this is not a valid, inspectable schema. Tool description is adequate (89 chars) but lacks guidance on when/why to use it. No parameter descriptions visible. The tool name lacks a clear action verb (should be 'call_openapi_endpoint' or similar). Tool definitions are inferred from OpenAPI specs at runtime, not explicitly registered with proper schemas, triggering the 50-point cap for inferred tools. No output schema documented. No error handling guidance.

• Rename tool to 'call_openapi_endpoint' or 'invoke_api_operation' to start with a clear action verb.
• Generate and register static input schemas for each discovered endpoint at server startup, rather than declaring additionalProperties=true. Each endpoint should have a named tool with explicit parameter types and descriptions.
• Document output schema in tool description: 'Returns HTTP response body (JSON or text) and status code. See OpenAPI spec for endpoint-specific response structure.'
• Add error handling guidance: 'If endpoint returns 4xx/5xx, check authentication, required parameters, and API rate limits. Refer to OpenAPI spec for endpoint-specific error codes.'
• Implement per-endpoint tool descriptions extracted from OpenAPI summary/description fields, including WHEN to call each endpoint and what it returns.
