How I verify 8 formats of credentials with a single API (ATC, JWT, W3C VC, A2A, EAT-AI, ZTA, MCP, X.509)
El problema de los 8 formatos Si construyes un agente IA hoy, vas a recibir credenciales de muchos lugares: Un MCP server que te pasa una "MCP Server Card" Un agente de Google A2A que te pasa una "A2A card" Un servicio W3C VC que te pasa un "Verifiable Credential" Un legacy system que te pasa un X.509 Un JWT OAuth estándar Un EAT-AI token (Entity Attestation Token) Un ZTA card (Zero Trust Agent)…
A new tool called Universal Trust Adapter (UTA) is being promoted to unify eight different digital credential formats. The formats include MCP Server Card, Google A2A card, W3C Verifiable Credential, X.509, JWT OAuth, EAT-AI token, ZTA card, and ATC v3. UTA offers an API that can automatically detect and verify credentials in any of these formats, and also translate between them.
The API has three main functions: verify, translate, and bridge, which allow users to check credentials, convert between formats, and verify and issue equivalent credentials across different ecosystems. According to benchmarks, UTA can perform up to 6,744 verifications per second on a single core.
