Connect GCIS (Taiwan Company Registration) to Gemini Enterprise
Query GCIS (Taiwan Company Registration) directly from Gemini Enterprise. Arlet links the two through one MCP connection and takes care of API keys.
This server connects your AI client to Taiwan's company registration open data, published by the Ministry of Economic Affairs (GCIS). It is the authoritative record of whether a Taiwanese company exists, who is responsible for it, and whether it is still in good standing - the Taiwan piece of a cross-border counterparty due-diligence workflow.
Key features:
- search_companies: search by Chinese company-name keyword. Active companies (核准設立) only by default, with an option to include dissolved or withdrawn ones.
- get_company: the registration record for one 8-digit unified business number (統一編號): official name, status, responsible person, authorized and paid-in capital, registered address, registration authority, establishment date and last change date.
Dates arrive in the ROC (Minguo) calendar and are converted to the Gregorian calendar automatically. The unified business number is the same identifier the TWSE server returns for listed companies, so the two join cleanly: find a listed company there, verify its registration here.
No API key is needed. Note that company names in the registry are official Chinese names - search in Chinese for best results.
