## What it does

The server connects your coding assistant directly to the Czech tax administration database. It exposes three operations: `check_dph_payer` for single-subject lookups, `check_bulk_dph_payer` for processing lists of company IDs, and `list_unreliable_payers` for full database synchronisation. The service classifies entities as `ANO` for unreliable taxpayers, `NE` for compliant businesses, or `NENALEZEN` when no registry entry exists.

Local execution of `@czagents/adis` requires the `ADIS_SOAP_ENABLED=1` environment variable. If you decide to query the hosted endpoint at `https://adis.cz-agents.dev/mcp`, requests are constrained by per-IP rate limits.

## When to use it
- verify Czech VAT payer reliability before approving supplier invoices
- retrieve registered bank account numbers associated with a Czech DIČ
- screen multiple supplier identification numbers in a single bulk pass
- mirror the national list of flagged VAT defaulters into local storage

## Example prompts
- Check VAT payer reliability and registered bank accounts for IČO 26168685.
- Run check_bulk_dph_payer on these DIČ values and list anyone flagged with ANO.
