What is Tiny Cryptography MCP Server?
This is a Model Context Protocol (MCP) server built with Express.js that offers cryptographic functionalities. It allows AI models and tools to communicate securely by providing tools for key exchange, shared secret derivation, and message encryption/decryption using the Stanford Javascript Crypto Library (SJCL).
How to use Tiny Cryptography MCP Server?
To use the server, first clone the repository and install the dependencies using npm install. Configure the PORT environment variable if needed. Start the development server with npm run dev or build and start the production server with npm run build and npm start. Connect to the server using Server-Sent Events (SSE) at the /sse endpoint. Use the API endpoints /messages/:id to send messages to specific connections. The server provides tools like generateKeyPair, deriveSharedSecret, encrypt, and decrypt to manage cryptographic operations.
