CVIN MCP

CVIN provides an MCP server for the Compute-asset Verification & Identification Number protocol, enabling agents to resolve GPU device identities, retrieve append-only observation histories, and verify continuity proofs. It supports free existence checks and paid access to full historical data and signed verification reports, facilitating automated due diligence for GPU leasing, collateralization, and procurement.

cvin_resolve_batch

Advertised by the server during the last successful anonymous check.
