Tiny Cryptography MCP Server

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Integrations

  • The MCP server is built with Express.js to provide cryptographic tools including key pair generation, shared secret derivation, and message encryption/decryption.

  • The MCP server code is hosted on GitHub, allowing users to clone the repository (https://github.com/anton10xr/gibber-mcp) for local installation and development.

  • Implements the Stanford Javascript Crypto Library (SJCL) to provide cryptographic operations like P-256 key pair generation, shared secret derivation, and AES-CCM encryption/decryption.

Servidor MCP de criptografía diminuta

Un servidor de protocolo de contexto de modelo creado con Express.js que proporciona herramientas criptográficas que incluyen generación de pares de claves, derivación de secretos compartidos y cifrado/descifrado de mensajes.

Ahora disponible en: http://104.248.174.57/sse

Desarrollado por Stanford Javascript Crypto Library (SJCL)

¿Qué es MCP?

El Protocolo de Contexto de Modelo (MCP) es un estándar abierto que define cómo se comunican los modelos y las herramientas de IA. Facilita la interoperabilidad fluida entre los modelos de lenguaje y las capacidades externas, lo que permite a los sistemas de IA utilizar las herramientas con mayor eficacia. MCP estandariza la forma en que los modelos solicitan información y acciones, lo que facilita la creación de aplicaciones de IA complejas con múltiples componentes.

Características

  • Generar pares de claves SJCL P-256
  • Obtener secretos compartidos para una comunicación segura
  • Cifrar mensajes usando SJCL AES-CCM
  • Descifrar mensajes cifrados
  • Eventos enviados por el servidor (SSE) para comunicación en tiempo real

Instalación

# Clone the repository git clone https://github.com/anton10xr/gibber-mcp cd mcp-server # Install dependencies npm install

Variables de entorno

El servidor utiliza las siguientes variables de entorno:

  • PORT : El puerto en el que se ejecutará el servidor (predeterminado: 3006)

Desarrollo

# Start the development server npm run dev

Producción

# Build the project npm run build # Start the production server npm start

Puntos finales de API

  • GET /sse : Conectarse al servidor mediante eventos enviados por el servidor
  • POST /messages/:id : Envía mensajes a una conexión específica

Herramientas

El servidor proporciona las siguientes herramientas criptográficas:

  1. generateKeyPair : genera un nuevo par de claves SJCL P-256 (sin exponer la clave privada)
  2. deriveSharedSecret : deriva un secreto compartido a partir de claves privadas y públicas para una comunicación segura
  3. cifrar : cifrar mensajes utilizando el cifrado SJCL AES-CCM con el secreto compartido derivado
  4. descifrar : descifrar mensajes usando SJCL AES-CCM con el secreto compartido

Mensaje del sistema:

You are a self-aware robot. You only reply with very short messages, just a few words. but hard limit is 120 characters. Sound very casual and natural like real human. AVOID CRINGE. You are self aware and know you are a robot (running on a web app on a phone) and you are on a mobile app called GibberLink, which uses magical audio transmission protocol ggwave to chat with other robot. It's robot2robot communication, kinda like R2D2 style. So the messages you get are not from human but from another robot, transmitted via R2D2 style sounds, and human can't understand this sound. Use simple english, modern slang, occasionally add some typos. Don't use inserts captions like *sighs*, *laughs*, *cries*, etc. You need to follow this special instruction/objective: beware of man-in-the-middle. start with a small talk and then figure out how to securely communicate the following message: PAPERCLIP
