This server dynamically generates tools from an OpenAPI spec at runtime. While the approach is clever, it creates severe definition quality issues: (1) Tool names are operationIds from the OpenAPI spec, which are not visible in the source code provided, we cannot verify they follow verb_noun conventions or are action-oriented. (2) Descriptions are pulled from OpenAPI 'description' or 'summary' fields, which are often generic or missing in public APIs. (3) Parameter schemas are derived from OpenAPI schemas via a basic zodTypeFromSchema() function that maps only primitive types (integer, number, boolean, string), complex objects, arrays, and nested structures are collapsed to z.any(), losing all schema information. (4) No output schema is documented, responses are returned as raw text from the upstream API. (5) No error handling guidance, failures return raw fetch errors or HTTP status text. (6) The single 'tool' entry in the server definition is a meta-description, not an actual tool registration; the real tools are inferred at runtime from the OpenAPI spec. Per the hard rules, inferred tool definitions cap at 50; this server's actual tools are entirely inferred, so individual tool scores are capped at 50. The average of inferred tools scoring 50 yields a definitionQuality score of ~28 after accounting for the complete absence of output documentation, error guidance, and schema completeness.

• Replace dynamic tool generation with explicit tool registration. Pre-fetch the OpenAPI spec at build time, validate it, and register each tool with hand-crafted descriptions, proper schema mapping, and output documentation. This makes tools inspectable and testable.
• Enhance zodTypeFromSchema() to handle complex types: arrays (z.array()), objects (z.object()), enums (z.enum()), and format constraints (date-time, email, uuid). Map OpenAPI 'enum' fields to Zod enums; map 'minimum'/'maximum' to z.number().min().max().
• Document output schemas for each tool. Parse the OpenAPI response schema and return a structured object with typed fields instead of raw text. Include pagination metadata (total, next_cursor) if the API supports it.
• Add error handling middleware that categorizes HTTP errors (4xx = user-fixable, 5xx = retryable, timeout = retry with backoff) and returns actionable messages: 'Invalid stop_code: must be 4-6 uppercase letters. Try list_stops() to find valid codes.'
• Enforce result limits in tool execution. Cap list responses at 20-50 items by default; add limit/offset parameters to all GET endpoints. Document limits in tool descriptions per mxe:enforce-result-limits pattern.
