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 16 EU 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."

Agent Skill

skills/cz-company-due-diligence is an Agent Skill that teaches Claude Code, Cursor, Copilot and other agents when and how to use these servers for Czech/EU company due diligence (KYC/AML, supplier and counterparty checks): which tool to call first, how to keep calls low on the free tier, how to handle tier_required and limits, how to tell a sanctions name match from a confirmed hit, and how to write a sourced, time-stamped report. It works fully on the free tier. Install from Agensi.

Install (Claude Code):

# 1. connect the free hosted servers
for s in dd ares isir sanctions adis eu-registry; do
  claude mcp add --transport http --scope user "$s" "https://$s.cz-agents.dev/mcp"
done
# 2. install the skill
git clone https://github.com/martinhavel/cz-agents-mcp.git
cp -r cz-agents-mcp/skills/cz-company-due-diligence ~/.claude/skills/
# 3. check: invoke /cz-company-due-diligence in Claude Code, then ask "Prověř firmu s IČO 45274649"
