   Title:   Trust Scoring and Identity Verification for Autonomous AI Agent Payment Transactions

Abstract:

   This document specifies a protocol for trust scoring, identity
   verification, and spend limit enforcement for autonomous AI agents
   that initiate financial transactions.  As AI agents gain the
   capability to make payments via protocols such as the Machine
   Payments Protocol (MPP), a standardised mechanism is needed to
   verify agent identity, assess trustworthiness, and enforce
   financial limits based on behavioural history.

   The protocol defines a five-dimension trust scoring model, per-
   agent cryptographic identity using ECDSA P-256 key pairs,
   challenge-response identity verification, spend limit tiers
   derived from trust scores, anomaly detection for financial
   behaviour, and a public trust query API for third-party platforms.

   This specification complements draft-sharif-mcps-secure-mcp, which
   provides message-level cryptographic security for the Model Context
   Protocol (MCP).  Together, the two specifications address protocol
   security (MCPS) and financial trust (this document) for the AI
   agent economy.
