Documentation Overview

thailand-data-mcp-server

MCP server exposing Thailand data tools for AI agents: official company-registry lookups, Thai address normalization, public holidays, and VAT/withholding-tax reference.

Tools

Tool	What it does
`thai_company_lookup`	Official DBD registry profile by 13-digit juristic ID: TH/EN name, type, status, registration date, registered/paid-up capital, business objective, registered address. Live data, cached 24h.
`thai_address_normalize`	Free-text Thai address (TH/EN) → structured province/district/subdistrict/postcode with official codes, confidence level, ambiguity candidates, and street-part extraction. Fully offline.
`thai_list_provinces`	Canonical list of all 77 provinces, bilingual, with codes.
`thai_holidays`	Thai public holidays (2025–2026) with lunar-holiday flags.
`thai_vat_reference`	VAT rate/threshold/filing + common WHT rates and the 50 ทวิ certificate rule. Reference only, not tax advice.

Install & run

bash

pnpm install
pnpm build
node dist/index.js            # stdio (default)
TRANSPORT=http PORT=3000 node dist/index.js   # streamable HTTP at /mcp (binds 127.0.0.1)

Claude Code registration:

Example

Code

thai_company_lookup {"juristic_id": "0107536000315"}
→ KASIKORNBANK PUBLIC COMPANY LIMITED | บริษัทมหาชนจำกัด | ยังดำเนินกิจการอยู่ | capital 30,246,820,970 THB | ...

thai_address_normalize {"address": "เลขที่ 5 ซอยสุขุมวิท 39 แขวงคลองตันเหนือ เขตวัฒนา กรุงเทพฯ"}
→ province กรุงเทพมหานคร / district วัฒนา / subdistrict คลองตันเหนือ / 10110 | confidence: high | street: "เลขที่ 5 ซอยสุขุมวิท 39"

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

bash

pnpm dev    # tsx watch

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