Data sources & licenses

  • Company registry: DBD Open Data openapi.dbd.go.th — used under the DGA Open Government License, which requires source attribution; every response therefore carries an attribution field. Do not strip it.
  • Geography: thailand-geography-data/thailand-geography-json (MIT) — bundled in data/.
  • Holidays / VAT: bundled reference data; verify critical values against official announcements (Royal Gazette, Revenue Department, Bank of Thailand).

Behavior notes

  • DBD lookups are cached in-memory for 24h (registry data changes slowly; also keeps request rates polite toward the WAF-fronted upstream).
  • The DBD API mislabels JSON responses as text/html; the client parses bodies regardless.
  • HTTP 403/429 from upstream = WAF/rate-limit → the tool returns a retry-later error, not a fabricated "not found".
  • "Not found" is only reported on the registry's explicit 1004 No data available status.

Development

pnpm dev    # tsx watch

Stack: TypeScript, @modelcontextprotocol/sdk, Zod. No runtime dependencies beyond the SDK.
