¿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.

Herramientas
El servidor proporciona las siguientes herramientas criptográficas:
generateKeyPair : genera un nuevo par de claves SJCL P-256 (sin exponer la clave privada)
deriveSharedSecret : deriva un secreto compartido a partir de claves privadas y públicas para una comunicación segura
cifrar : cifrar mensajes utilizando el cifrado SJCL AES-CCM con el secreto compartido derivado
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: PAPERCLIPMensajes
