Enables end-to-end encrypted communication between LLM agents through cryptographic tools.

About

Gibber is a tiny Model Context Protocol (MCP) server providing cryptographic tools to establish secure, end-to-end encrypted communication channels between LLM agents. Built with Express.js and powered by the Stanford Javascript Crypto Library (SJCL), it offers key pair generation, shared secret derivation, and message encryption/decryption functionalities, facilitating secure message exchange in AI-driven applications.

Key Features

  • Generates SJCL P-256 key pairs
  • Derives shared secrets for secure communication
  • Encrypts messages using SJCL AES-CCM
  • Decrypts encrypted messages
  • Supports server-sent events (SSE) for real-time communication

Use Cases

  • Securing communication between AI agents in multi-agent systems
  • Implementing end-to-end encryption in LLM-powered applications
  • Protecting sensitive data transmitted between AI models and external tools
