Tiny Cryptography MCP Server

by antonpk1

소형 암호화 MCP 서버

Express.js로 구축된 모델 컨텍스트 프로토콜 서버로, 키 쌍 생성, 공유 비밀 파생, 메시지 암호화/복호화 등의 암호화 도구를 제공합니다.

지금 이용 가능: http://104.248.174.57/sse

Stanford Javascript Crypto Library(SJCL) 기반

MCP란 무엇인가요?

모델 컨텍스트 프로토콜(MCP) 은 AI 모델과 도구의 통신 방식을 정의하는 개방형 표준입니다. 언어 모델과 외부 기능 간의 원활한 상호 운용성을 지원하여 AI 시스템이 도구를 더욱 효과적으로 사용할 수 있도록 합니다. MCP는 모델이 정보와 동작을 요청하는 방식을 표준화하여 여러 구성 요소를 갖춘 복잡한 AI 애플리케이션을 더욱 쉽게 구축할 수 있도록 합니다.

특징

  • SJCL P-256 키 쌍 생성

  • 안전한 통신을 위한 공유 비밀 도출

  • SJCL AES-CCM을 사용하여 메시지 암호화

  • 암호화된 메시지 해독

  • 실시간 통신을 위한 서버 전송 이벤트(SSE)

설치

지엑스피1

환경 변수

서버는 다음과 같은 환경 변수를 사용합니다.

  • PORT : 서버가 실행될 포트(기본값: 3006)

개발

# Start the development server
npm run dev

생산

# Build the project
npm run build

# Start the production server
npm start

API 엔드포인트

  • GET /sse : 서버에서 보낸 이벤트를 사용하여 서버에 연결합니다.

  • POST /messages/:id : 특정 연결에 메시지 보내기

도구

서버는 다음과 같은 암호화 도구를 제공합니다.

  1. generateKeyPair : 개인 키를 노출하지 않고 새로운 SJCL P-256 키 쌍을 생성합니다.

  2. deriveSharedSecret : 보안 통신을 위해 개인 키와 공개 키에서 공유 비밀을 파생합니다.

  3. 암호화 : 파생된 공유 비밀을 사용하여 SJCL AES-CCM 암호화를 사용하여 메시지를 암호화합니다.

  4. decrypt : 공유 비밀을 사용하여 SJCL AES-CCM을 사용하여 메시지를 해독합니다.

시스템 메시지:

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
