dev.cz-agents/dd is an MCP server that runs Czech and EU business due diligence with risk scoring and UBO chain in one agent call.
About
dev.cz-agents/dd is an MCP server that aggregates Czech and European due diligence signals so your coding agent can assess a legal entity without you juggling national registers, sanctions lists, and VAT portals. founders validating B2B partnerships, marketplaces onboarding suppliers, or agencies checking clients before large retainers get structured outputs: factual registry data, insolvency posture, sanction hits, VAT context, a computed risk score, and UBO chain visibility. It is designed as a compliance-oriented integration for agent-driven workflows, not a replacement for licensed KYC platforms or legal counsel. Use the remote streamable-http endpoint for zero install or the npm stdio transport for local dev. Pair it with your own decision rubric in the agent prompt; the server focuses on fetching and normalizing authoritative checks rather than filing regulatory reports for you.

What it does
Run Czech and EU company due diligence from the agent—registry facts, insolvency, sanctions, VAT, risk score, and UBO—in one MCP call before signing deals.
Who is it for?
EU-facing B2B products, marketplaces, or consultancies that must sanity-check Czech/EU companies inside Claude Code or Cursor.
Skip if: Skip if you need enterprise KYC case management, document collection, or non-EU-only vendor bases with no CZ/EU exposure.
What you get
One MCP tool call returns consolidated facts, risk signals, and UBO structure so you can approve or reject a deal with evidence in the thread.
- Structured due diligence payload: facts, insolvency, sanctions, VAT, risk score, UBO chain
- Agent-ready evidence bundle for go/no-go partner decisions

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/ddaggregator 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."
