한국어

Prometheus-MCP는 Claude, GPT, DeepSeek, MiniMax, Qwen, GLM 및 미래 모델이 생성한 크리에이티브 산출물을 전문가 수준으로 끌어올리는 Model Context Protocol 서버입니다. 단순한 문서 검색 시스템이 아니라, 생성 - 평가 - 개선 - 재생성 루프를 통해 품질을 지속적으로 향상시키는 AI Creative Director입니다.

대상 분야

  • 웹 디자인 / UI 디자인 / UX 디자인
  • Three.js / React Three Fiber / WebGL / WebGPU
  • VFX / 셰이더 (GLSL / WGSL) / 인터랙티브 경험
  • 프론트엔드 애니메이션 / 크리에이티브 코딩
  • 게임 개발 (2D / 3D / Phaser / Rapier / ECS)

핵심 가치

  1. 전문가 패턴 라이브러리 - 22개 패턴, 확장 가능한 구조
  2. Critic Engine - 16개 품질 차원, 60개 규칙, 증거 기반 평가
  3. 자동 개선 루프 - 목표 점수 도달까지 반복
  4. 품질 인텔리전스 - 감사 가능한 점수 근거
  5. AI 크리에이티브 디렉팅 - 패턴 선택, 개선 전략, 재생성

설치 및 실행

npm install
npm run build
npm start

opencode 로컬 MCP 연결

프로젝트 루트에 opencode.json을 생성하고 Prometheus를 로컬 MCP로 등록합니다. API 키 불필요 (StubProvider 기본 활성화).

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "prometheus": {
      "type": "local",
      "command": ["node", "E:/Downloads/Prometheus-MCP/dist/index.js"],
      "enabled": true
    }
  }
}

opencode 재시작 후 7개 도구(direct_creative_work, critique_artifact 등)가 에이전트에 연결됩니다.

Claude Desktop 연결

claude_desktop_config.json에 추가:

{
  "mcpServers": {
    "prometheus": {
      "command": "node",
      "args": ["E:/Downloads/Prometheus-MCP/dist/index.js"]
    }
  }
}

테스트

npm test

설정

환경 변수로 런타임 설정을 덮어쓸 수 있습니다.

변수 설명
PROMETHEUS_TARGET_SCORE 목표 품질 점수 (기본 85)
PROMETHEUS_MAX_ITERATIONS 최대 개선 반복 (기본 5)
PROMETHEUS_MAX_COST_USD 비용 상한 (USD)
PROMETHEUS_DEFAULT_PROVIDER 기본 모델 제공자
PROMETHEUS_ENABLE_LLM_REASONING LLM 추론 평가 활성화
PROMETHEUS_ALLOW_COMMUNITY_PATTERNS 커뮤니티 패턴 허용

모델 제공자 API 키는 해당 환경 변수(OPENAI_API_KEY, ANTHROPIC_API_KEY, DEEPSEEK_API_KEY 등)가 존재하면 자동 활성화됩니다.

English

Prometheus-MCP is a Model Context Protocol server that elevates creative output from Claude, GPT, DeepSeek, MiniMax, Qwen, GLM, and future models to expert-level quality. It is not a document retrieval system. It is an AI Creative Director that runs a generate - critique - improve - regenerate loop to continuously raise quality.

Target Domains

  • Web design / UI design / UX design
  • Three.js / React Three Fiber / WebGL / WebGPU
  • VFX / shaders (GLSL / WGSL) / interactive experiences
  • Frontend animation / creative coding
  • Game development (2D / 3D / Phaser / Rapier / ECS)

Core Value

  1. Expert Pattern Library - 22 patterns, extensible structure
  2. Critic Engine - 16 quality dimensions, 60 rules, evidence-bound evaluation
  3. Auto Improvement Loop - iterates until target score is reached
  4. Quality Intelligence - auditable score justifications
  5. AI Creative Directing - pattern selection, improvement strategy, regeneration

  -> Knowledge Collector
  -> Pattern Selector
  -> Prompt Enhancer
  -> Generation Provider
  -> Evidence Collector
  -> Critic Engine

critic evidence collection (deterministic measurement) + rule evaluation + scoring + auditable justification
improver surgical/full regeneration strategy, revision prompts
loop_controller state machine + termination policy (target/maxIter/cost/wallClock/diminishing returns)
providers capability-based router (Stub, OpenAI-compatible, Claude)
memory cross-session learning, effectiveness tracking
history intra-session timeline
telemetry structured logs, metrics, cost, tracing, secret redaction
infrastructure config, cache, security
mcp 7 tools / 5 resources / 4 prompts

MCP Tools

Tool Description
direct_creative_work runs generate-critique-improve loop from a brief
critique_artifact evaluates an artifact (score, strengths, weaknesses, suggestions)
improve_artifact builds improvement plan + revision prompt from a critique
list_patterns lists available patterns
get_pattern gets pattern detail
recall_sessions recalls past sessions
get_quality_trends analyzes quality trends

Install and Run

npm install
npm run build
npm start

opencode Local MCP

Create opencode.json in your project root and register Prometheus as a local MCP. No API key needed (StubProvider enabled by default).

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "prometheus": {
      "type": "local",
      "command": ["node", "E:/Downloads/Prometheus-MCP/dist/index.js"],
      "enabled": true
    }
  }
}

Restart opencode and the 7 tools (direct_creative_work, critique_artifact, etc.) become available to the agent.

Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "prometheus": {
      "command": "node",
      "args": ["E:/Downloads/Prometheus-MCP/dist/index.js"]
    }
  }
}

Tests

npm test

Configuration

Environment variables override runtime config.

Variable Description
PROMETHEUS_TARGET_SCORE target quality score (default 85)
PROMETHEUS_MAX_ITERATIONS max improvement iterations (default 5)
PROMETHEUS_MAX_COST_USD cost cap (USD)
PROMETHEUS_DEFAULT_PROVIDER default model provider
PROMETHEUS_ENABLE_LLM_REASONING enable LLM reasoning in critique
PROMETHEUS_ALLOW_COMMUNITY_PATTERNS allow community-trust patterns

Model provider API keys auto-enable their providers when the corresponding env var (OPENAI_API_KEY, ANTHROPIC_API_KEY, DEEPSEEK_API_KEY, etc.) is present.
