About
Thai data for AI agents: DBD company-registry lookup, address normalization, holidays, VAT/WHT.
Security Report
A well-structured MCP server for Thailand data lookup tools with no critical vulnerabilities. Authentication is not applicable (all tools are reference data or public APIs). Code quality is solid with proper input validation, error handling, and caching. Minor findings include broad CORS configuration in the Apify deployment and lack of rate-limiting on the geography parser, but these are low-severity and do not materially affect security. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.

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 anattributionfield. 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 availablestatus.
