Mawyxx proposed a security pattern for Model Context Protocol (MCP) that uses bearer JSON Web Tokens (JWT) and JSON Web Key Sets (JWKS) to authenticate headless AI agents without exposing a master sec…

A developer built LIME, a cryptographic identity layer for AI agents that provides signed JWT passports (RS256) verifiable by any website in under 10ms via a JWKS endpoint. The system uses Proof-of-Wo…

The article explains that JSON Web Tokens (JWTs) signed with current algorithms like RS256 and ES256 are vulnerable to future quantum computer attacks, with nation-state actors already employing "harv…
