MCP is the open protocol for AI agents — Claude, OpenClaw, Hermes, your own agent loop. Twinkle Hub bundles Taiwan data sources behind a single MCP endpoint — set your client up once, AI can query datasets, run SQL, and call tools.

New corpus: Taiwan tourism statistics — 70-year monthly series of inbound/outbound travelers, cruise, scenic spots
datasets
37
✓37 new datasets (`tad-*` prefix) mirroring the Taiwan Tourism Administration's official statistics database — **70-year complete time series since 1956**
✓4 themes: **inbound visitors** (by nationality / residence / age / gender / purpose / length of stay / spending), **outbound citizens** (by destination / gender / age / transport mode), **cruise passengers**, **annual visitor counts** at scenic spots
✓**Monthly + yearly dual time series**: supports both same-month YoY queries (2025-05 vs 2024-05) and annual-overview comparisons (2019 / 2024 / 2025)
Try asking:
Top 10 inbound visitor nationalities in 2025 vs 2019
Distribution of length-of-stay for Japanese visitors over the years
✓We rebuilt the drug-leaflet search back-end on top of a pre-built index. Three tools now answer in single-digit milliseconds: `opendata-search_drug_label` (precise leaflet-field search), `opendata-check_drug_interaction` (scan 2–10 drug leaflets for interactions), and the leaflet-merge stage inside `opendata-get_drug_details`
✓Warm-cache latency measured live: leaflet-field search 1.78 ms (down from 50–200 ms); two-drug interaction scan 0.27 ms
✓The drug-licence registry search (`opendata-search_drug` and friends) still uses the previous path and will move in the next release — this ship focuses the highest-traffic surface first
Try asking:
Drugs whose leaflet mentions both warfarin and NSAIDs (noticeably faster)
Taiwan data is scattered across 100+ portals. AI app builders don't have time to wire each one.
Twinkle Hub bundles them into a single MCP service: discover datasets, fetch rows, join across tables, pay — all on one endpoint. Phase one is making data.gov.tw excellent; more sources (industry associations, local governments, commercial data) come next.
01
One MCP endpoint
Every source, every domain, every tool under the same URL. Configure your client once.
02
Deterministic billing
Fixed price per tool — no token-based gambling. Prepaid wallet, hard cutoff, no surprise bills.
03
License compliance
Original license metadata is passed through end-to-end so downstream apps don't trip license terms.
04
MCP-native protocol
tools/list / tools/call are native endpoints, not OpenAI tool-calling translated. Claude / OpenClaw / Hermes / Continue / Cline / your own agent loop — same wire format, no SDK, no adapter.
Why Twinkle Hub
Downloading 53,000 datasets is easy. Making them usable to AI is the hard part.
Making Taiwan open data usable to AI isn't a one-off catalog download. We handle the cleanup, conversion, classification, and querying — your AI just calls the API instead of crawling a hundred different portals.
52,960 / 19
53,000 datasets, sorted automatically
All 52,960 datasets on data.gov.tw, sorted into 19 categories. New ones land in the right place the next day — the index never ages out.
10+ formats
All the file formats, one shape
CSV, JSON, Excel, PDF, geo files — whatever the format, we read it and clean up the column names. Your AI doesn't choke just because one source is PDF and another is XLSX.
~50 ms
Ask a question, answer in 50 ms
Want your AI to query data on specific conditions? We have a query layer — about 50 ms across all 53,000 datasets. We don't dump a zip and tell you to process it yourself.
Daily refresh
Synced with the government every day
A daily cron pulls the latest catalog, picks up what's new or retired, runs classification. The data stays fresh — it doesn't go stale because we forgot to update.
Beyond the data
One thing we wired up alongside
OpenData is the main course. This one also matters for agents — we did it too.
20 official Anthropic Agent Skills. Load one into Claude Desktop / Claude Code / GitHub Copilot CLI / OpenAI Codex CLI — or any MCP-compatible agent — and it already knows which tool to call, which filter to use, and what a typical query looks like.
2026-05-31 internal benchmark — Phase 1 plan-only across 11 skill domains, Claude Opus 4.7 subagent A/B (incl. Round 2 narrow-domain: health/finance/environment/agriculture); Phase 2 real MCP (LVR query: "Taipei Da'an 2024 transactions over NT$50M"). Single-query sample; cold-start and retry costs not included. See full report for caveats.
