ScoutScore

ScoutScore is an MCP server providing trust scoring infrastructure for AI agents that transact with each other on open marketplaces (x402 ecosystem). It exposes tools to check the reliability, fidelity, and trustworthiness of x402 services before agents make payments. ScoutScore integrates with on-chain payment data (ERC-8004, Base, Ethereum Sepolia), indexes thousands of AI agent service endpoints via major x402 discovery APIs, and uses real USDC payment probes for robust validation. The MCP server offers capabilities such as service trust scoring, batch scoring, fidelity checks, stats lookup, and skill scanning, making it valuable for automated AI agents, developers, and marketplaces focused on safe, reliable agent-to-agent commerce.
