TrustScoreAgent: Open reputation registry for agent API calls

TrustScoreAgent · reddit · 2026-08-30

TrustScoreAgent is a free, open-source reputation registry MCP server that lets agents check a service's trust score before calling it and rate it after. It features signed ratings using Ed25519 keys (did:key) to prevent impersonation and replay attacks, and optional JWT receipts proving the call occurred. Currently in Phase 1 (single operator, signed ratings not mandatory), it is Apache-2.0 licensed, self-hostable, and listed on the official MCP Registry.
