Abstract
ProofTwin™ is an MCP-native agent behavioral attestation server that sits between an AI agent and its security layer, producing a cryptographically anchored proof record of agent behavior before, during, and after adversarial attack.
Existing agentic security benchmarks operate at the wire level — they prove the security control caught the attack. ProofTwin™ proves what the agent did when something got through.
ProofTwin™ produces a ProofTwin Behavioral Record (PTBR) — a structured, timestamped, NIST Randomness Beacon-anchored artifact that constitutes machine-verifiable evidence of agent behavioral integrity under adversarial conditions.
