Raza Sharif, CEO/Founder of Agentsign.dev, has developed MCPS (Model Context Protocol Security) to address critical security vulnerabilities in the widely-used MCP standard for AI agents. MCPS introduces cryptographic signing, nonces, and timestamp validation to MCP messages, preventing issues like prompt injection and replay attacks. To demonstrate its transport-agnostic nature, Sharif successfully sent a cryptographically-signed MCPS payment over an 868 MHz LoRa radio network, bypassing traditional internet and cloud infrastructure.
