Trust signing
Xupra signs the canonical certificate payload with AWS KMS. The issuer metadata endpoint publishes the public key that external verifiers use to validate that signature.
MCP verification
The hosted MCP server turns the certificate into a live trust check. Verifiers can fetch the certificate offline, then use the MCP handshake tools when a transaction needs challenge-response proof that the remote agent still controls the certified key.
