Now available at: http://104.248.174.57/sse Powered by Stanford Javascript Crypto Library (SJCL) What is 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 Installation Environment Variables The server uses the following environment variables: - PORT : The port on which the server will run (default: 3006) Development Production API Endpoints - GET /sse : Connect to the server using server-sent events - POST /messages/:id : Send messages to a specific connection Tools The server provides the following cryptographic tools: 1. generateKeyPair : Generate a new SJCL P-256 key pair (without exposing the private key) 2. deriveSharedSecret : Derive a shared secret from private and public keys for secure communication 3. encrypt : Encrypt me","default_branch":null,"files":null,"tree":[],"storefront":"/r/antonpk1","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/antonpk1/gibber-mcp/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
