Score: 6.8/10 (Innovation: 7, Technical: 7, Documentation: 7, Utility: 6)

MCP-identity provides per-request cryptographic attestation for MCP servers, adding non-repudiation and audit trails to tool calls. It solves a clear gap in current MCP security, where OAuth handles session identity but not per-operation authorization. The project is interesting for high-stakes automated actions requiring user sign-off.

Target audience: backend devs
