What is the Nubarium MCP Server?
Empower your AI agent to orchestrate your entire Mexican identity and corporate research workflow with Nubarium, the leading platform for Mexican data intelligence. By connecting Nubarium to your agent, you transform complex national lookups into a natural conversation. Your agent can instantly validate RFC (Tax ID) and CURP (Identity ID) records, audit company profiles, and verify legal representative status without you ever touching a manual portal. Whether you are conducting KYC checks or regional due diligence, your agent acts as a real-time institutional analyst, ensuring your Mexican data is always verified and up-to-date.

- Identity Auditing — Validate Mexican CURP records and retrieve detailed personal metadata, including names and birth details.
