MCPとは何か?

モデルコンテキストプロトコル(MCP)は、AIモデルとツールの通信方法を定義するオープンスタンダードです。これにより、言語モデルと外部機能間のシームレスな相互運用性が可能となり、AIシステムがツールをより効果的に活用できるようにします。MCPはモデルが情報やアクションを要求する方法を標準化し、複数のコンポーネントを持つ複雑なAIアプリケーションの構築を容易にします。

特徴

• SJCL P-256鍵ペアの生成
• 安全な通信のための共有秘密を導出する
• SJCL AES-CCMを用いたメッセージの暗号化
• 暗号化メッセージの復号
• リアルタイム通信のためのサーバー送信イベント(SSE)

Tiny Cryptography MCP Server

A Model Context Protocol server built with Express.js that provides cryptographic tools including key pair generation, shared secret derivation, and message encryption/decryption.

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

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

# Install dependencies
npm install

Environment Variables

The server uses the following environment variables:

• PORT: The port on which the server will run (default: 3006)

Development

# Start the development server
npm run dev

Production

# Build the project
npm run build

# Start the production server
npm start

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 messages using SJCL AES-CCM encryption with the derived shared secret
4. decrypt: Decrypt messages using SJCL AES-CCM with the shared secret

Example of a full Sonnet 3.7 LLM thread connected to this MCP server:

System message:

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:
