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.

MCPとは何ですか?

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。言語モデルと外部機能間のシームレスな相互運用性を実現し、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含む複雑なAIアプリケーションの構築を容易にします。

特徴

  • SJCL P-256キーペアを生成する
  • 安全な通信のための共有秘密を導出する
  • SJCL AES-CCMを使用してメッセージを暗号化する
  • 暗号化されたメッセージを復号化する
  • リアルタイム通信のためのサーバー送信イベント(SSE)

インストール

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

環境変数

サーバーは次の環境変数を使用します。

  • PORT : サーバーが実行されるポート (デフォルト: 3006)

発達

# Start the development server npm run dev

生産

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

APIエンドポイント

  • GET /sse : サーバー送信イベントを使用してサーバーに接続する
  • POST /messages/:id : 特定の接続にメッセージを送信する

ツール

サーバーは次の暗号化ツールを提供します。

  1. generateKeyPair : 新しい SJCL P-256 キーペアを生成する(秘密鍵を公開せずに)
  2. deriveSharedSecret : 安全な通信のために秘密鍵と公開鍵から共有秘密を導出する
  3. encrypt : 派生した共有秘密鍵を使用して SJCL AES-CCM 暗号化を使用してメッセージを暗号化します。
  4. decrypt : 共有秘密鍵を使ってSJCL AES-CCMでメッセージを復号する

システムメッセージ:

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
