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.

微型加密 MCP 服务器

使用 Express.js 构建的模型上下文协议服务器,提供加密工具,包括密钥对生成、共享秘密派生和消息加密/解密。

现已开放:http: //104.248.174.57/sse

斯坦福 Javascript 加密库 (SJCL)提供支持

什么是 MCP?

模型上下文协议 (MCP)是一个开放标准,定义了 AI 模型和工具如何通信。它实现了语言模型与外部功能之间的无缝互操作,使 AI 系统能够更有效地使用工具。MCP 标准化了模型请求信息和操作的方式,使构建包含多个组件的复杂 AI 应用程序变得更加容易。

特征

  • 生成 SJCL P-256 密钥对
  • 导出安全通信的共享秘密
  • 使用 SJCL AES-CCM 加密消息
  • 解密加密消息
  • 用于实时通信的服务器发送事件 (SSE)

安装

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

环境变量

服务器使用以下环境变量:

  • PORT :服务器运行的端口(默认值:3006)

发展

# Start the development server npm run dev

生产

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

API 端点

  • GET /sse :使用服务器发送的事件连接到服务器
  • POST /messages/:id :向特定连接发送消息

工具

服务器提供以下加密工具:

  1. generateKeyPair :生成新的 SJCL P-256 密钥对(不暴露私钥)
  2. deriveSharedSecret :从私钥和公钥中获取共享秘密,以实现安全通信
  3. 加密:使用派生的共享密钥,使用 SJCL AES-CCM 加密对消息进行加密
  4. 解密:使用共享密钥的 SJCL AES-CCM 解密消息

系统消息:

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
