Korea Business Verify

A local MCP server that lets an assistant verify Korean business registration details, check business status and tax type, and judge tax-invoice eligibility via

What you can do

Verify a Korean business registration by matching business number, representative name and opening date against National Tax Service data. Check whether a business is active or closed, its tax type and closure date. Batch-check the status of up to 100 business numbers at once. Judge whether a tax invoice can be issued and return the stated basis. Explain what general, simplified, exempt and non-taxable tax types mean in practice.

When to use it

Useful when an assistant handles Korean vendor onboarding, expense or settlement checks, or invoice preparation and needs to confirm a business number is real and still trading. Also handy for bulk screening of supplier lists.

Requirements

Runs locally via npx or a built Node.js package. Live mode needs a National Tax Service service key from the public data portal, supplied as the NTS_SERVICE_KEY environment variable; the key must be requested separately for the verification and status services. Without a key it runs in demo mode with fictitious business numbers. Network access to the National Tax Service API is required.
