v2.1.1

Fixed

• serverInfo.version was stuck at 1.0.8 in src/server.ts even after 1.1.0 / 2.0.0 / 2.1.0 published. Smithery's admin probe reads result.serverInfo.version from the initialize response; the wire-level identity has been silently lying about the package version since the 1.0.7 fix. Replaced the hard-coded literal with a runtime createRequire('../package.json') read so the wire version always matches the npm-published release. Now reports 2.1.1.
• server.json description undercounted tools ("18 freight tools …"). Updated to "19 freight tools …, get_subscribe_link" to match the 19-tool surface shipped in 2.1.0.

Improved

• Tighter Zod input constraints for better agent-side errors:
  • airline_lookup: iata.length(2), icao.length(3), prefix.regex(/^\d{3}$/), query/country min 2 chars.
  • adr_lookup, adr_exemption_calculator, adr_lq_eq_check: un_number.regex(/^(UN)?\d{4}$/i) (top-level and inside items[]).
  • unlocode_lookup: code.length(5).regex(/^[A-Z0-9]{5}$/i), country.length(2).regex(/^[A-Z]{2}$/i), limit.min(1).max(100).
  • uk_duty_calculator: commodity_code.regex(/^\d{6,10}$/), origin_country.length(2).regex(/^[A-Z]{2}$/i).
• .strict() declared on every top-level tool schema — applied across all 19 tools at the source level. NOTE: this is a no-op at the wire today because the deprecated server.tool() overload passes only schema.shape to the SDK, which rebuilds the object in default strip mode (verified in @modelcontextprotocol/sdk@1.26 mcp.js#getZodSchemaObject → objectFromShape). .strict() will become wire-effective once the planned migration to server.registerTool() ships (audit finding #4, slated for 2.2.0). Field-level constraints above (regex/length/min/max) DO take effect at the wire — verified by smoke test.

Notes

No tool-call wire breakage. All previously-valid inputs remain valid; the new field-level constraints only reject inputs that were already malformed (e.g., a 4-letter IATA code, a country name in an ISO-2 slot). Tool surface, names, descriptions, and annotations are unchanged.
