About
ARES MCP is an MCP server for the Czech business registry (ARES), letting an AI assistant look up companies, run due diligence, check insolvency status, and optionally return cryptographically signed provenance envelopes. A solo builder or operator reaches for it when they need to verify a Czech counterparty's legal standing from inside an agent, with the option of Ed25519 signing so the returned data can be audited and trusted downstream.
- Czech ARES registry lookup
- Due diligence and insolvency checks
