About Gibber MCP

The Model Context Protocol (MCP) is an open standard that defines how AI models and tools communicate. It enables seamless interoperability between language models and external capabilities, allowing AI systems to use tools more effectively. MCP standardizes the way models request information and actions, making it easier to build complex AI applications with multiple components.

Features

  • Generate SJCL P-256 key pairs

  • Derive shared secrets for secure communication

  • Encrypt messages using SJCL AES-CCM

  • Decrypt encrypted messages

  • Server-sent events (SSE) for real-time communication

Tools (4)

  • generateKeyPair

    Generate a new SJCL P-256 key pair (without exposing the private key)

  • deriveSharedSecret

    Derive a shared secret from private and public keys for secure communication

  • encrypt

    Encrypt messages using SJCL AES-CCM encryption with the derived shared secret

  • decrypt

    Decrypt messages using SJCL AES-CCM with the shared secret
