Summary

Provides programmatic access to the Czech Insolvency Register (ISIR) for screening companies and individuals against active bankruptcy proceedings. Exposes three tools: check_ico_insolvency for direct company lookups by IČO, search_person_insolvency for querying by birth number or name, and poll_isir_events for monitoring new filings. Part of the larger cz-agents suite built for KYC workflows in Czech business contexts. Marked alpha, so expect evolving interfaces. Useful when you need to verify a vendor or invoice issuer isn't in active insolvency before signing or paying. Supports both local stdio execution via npx and remote streamable HTTP. Can optionally enable SOAP mode with an environment variable for richer data.

CI License: MIT MCP Registry Glama

Model Context Protocol servers for Czech & EU government and business data. Native access to ARES (company registry), ČNB (FX rates), ADIS (VAT-payer status), ISIR (insolvency), EU + OFAC sanctions screening, and EU business registries (GB/SK/PL/NL/DE/FR) — plus a unified due-diligence aggregator that combines them into risk scoring and statutory-chain (UBO) analysis.

Want a hosted, production-ready version? cz-agents.dev — managed API with a 14-day free trial (no credit card). Adds higher quotas, nominee detection, risk timeline, address crowding, watchlist monitoring, and a web compliance dashboard. Your self-hosted config keeps working after upgrade — same endpoints, same token format.

What this is good for

A toolkit for compliance, KYC/AML, accounting and cross-border checks over Czech & EU registries:

  • VAT & invoicing — verify VAT-payer status (ADIS) and convert at official ČNB FX rates before booking.
  • Counterparty screening — ARES identity, EU + OFAC sanctions, ISIR insolvency.
  • Due diligence (flagship) — the @czagents/dd aggregator combines the above into a risk score, statutory-chain / UBO walk, and EU-parent lookup.
  • Cross-border — company lookups across GB / SK / PL / NL / DE / FR registries (@czagents/eu-registry).

Use a single-source server when you need just one dataset; use the due-diligence aggregator for combined, scored output.

Example prompts the aggregator handles well:

  • KYC pre-invoice — "Before we send a 350 000 Kč invoice to IČO 11122234, flag any insolvency, sanctions, unreliable-VAT-payer status, or nominee-director red flags."
  • Vendor onboarding — "Run KYC on this prospective supplier and tell me if anything looks off. Use the full statutory chain."
  • M&A pre-due-diligence — "Generate a DD report on the acquisition target and walk the statutory body two levels deep — flag any insolvent firms in the network."
