v2.5.0

Changed

• Loose-schema tightening across the tool inputs — garbage is now rejected at the schema layer while every legitimate input form still validates. Several tools advertised a bare z.string() where the description promised a specific format, so malformed values passed validation and only failed (or silently returned nothing) downstream. Each is now constrained to exactly the forms its underlying data/logic accepts, with a clear error message, without narrowing any feature:
  • unit_converter — from is now an enum of the 17 supported unit codes (weight / volume / length); to is those plus the freight targets chargeable_kg and freight_tonnes. Unknown units are rejected with the valid set surfaced in tools/list.
  • hs_code_lookup — code must be 2–6 digits, section a Roman numeral (I–XXI), query ≥ 2 chars.
  • incoterms_lookup — code must be a 3-letter Incoterm code (any case).
  • uk_duty_calculator — incoterm is now the 11-value Incoterms enum (commodity_code ^\d{6,10}$ and origin_country ^[A-Za-z]{2}$ were already tight; regex form aligned with the website surface).
  • airline_lookup — iata ^[A-Za-z0-9]{2}$, icao ^[A-Za-z]{3}$ (upgraded from length checks); the 2-char IATA / 3-char ICAO / 3-digit AWB-prefix / free-form country+query union is fully preserved.
  • unlocode_lookup — the function filter is now function_type (an enum of port | airport | rail | road | icd | border), renamed from the previous bare-string function to match the website MCP surface and validated as an enum; code / country regexes aligned to the website (^[A-Za-z0-9]{5}$ / ^[A-Za-z]{2}$). Note: callers that passed function must switch to function_type.
  • container_lookup / uld_lookup / vehicle_lookup — the slug/code selector now requires ≥ 2 chars; these accept a code or slug from a fixed reference set, so they stay permissive (the handler returns a clear "not found" for unknown values) rather than being narrowed to a brittle enum.

Notes

• No tool-count or tool-list change — still 19 tools, same names. This is a FAULT 13 fix-once-mirror-everywhere release: the website /api/mcp surface (app/api/mcp/[transport]/route.ts) was tightened to the identical schemas in the same change, so tools/list and input validation match across both surfaces. serverInfo.version reads dynamically from package.json, now 2.5.0. Minor bump because the advertised input schemas changed (stricter validation + the unlocode_lookup function → function_type rename).
