설치

클라이언트 선택

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "everart": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everart"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config 열기. 저장 후 앱 재시작.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "everart": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everart"
      ]
    }
  }
}

Cursor는 Claude Desktop과 동일한 mcpServers 스키마 사용. 프로젝트 설정이 전역보다 우선.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "everart": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everart"
      ]
    }
  }
}

Cline 사이드바의 MCP Servers 아이콘 클릭 후 "Edit Configuration" 선택.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "everart": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everart"
      ]
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "everart",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-everart"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "everart": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "@modelcontextprotocol/server-everart"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add everart -- npx -y @modelcontextprotocol/server-everart

한 줄 명령. claude mcp list로 확인, claude mcp remove로 제거.

사용 사례

실전 활용법: EverArt

Generate OG / social card images for blog posts

👤 Content writers, solo devs running a blog ⏱ ~10 min beginner

언제 쓸까: You just wrote a post and need a 1200×630 social card before publishing.

사전 조건

EverArt API key — everart.ai → account → API keys. Set as EVERART_API_KEY.

흐름

Draft the prompt from the article

My post is titled 'How we cut p99 latency in half'. Propose 3 image prompts that capture that visually — abstract, not literal, tech-editorial style.✓ 복사됨

→ 3 distinct prompt candidates
Generate variations

Use EverArt to generate image_count=3 for the prompt I pick. Use the FLUX1.1 model for cleaner composition.✓ 복사됨

→ 3 URLs returned
Pick and save

I like #2. Download it to ./public/og/<slug>.png via the filesystem MCP.✓ 복사됨

→ File saved locally, ready for deploy

결과: A publish-ready OG card in 5 minutes, no design app open.

함정

Generated images have artifacts (weird text, extra fingers) — Skip prompts that ask for text in the image — let the model do abstraction and overlay your title via CSS/HTML
Aspect ratio doesn't match 1200×630 — The model outputs 1024×1024 by default — crop/resize via an image tool or accept square

함께 쓰기: filesystem

Generate a landing page hero image

👤 Founders, marketers on tight budgets ⏱ ~15 min beginner

언제 쓸까: Pre-launch landing page, no designer, stock photos feel generic.

흐름

Describe the vibe

My product is <description>. Target audience: <persona>. Propose 3 hero image directions that would feel authentic.✓ 복사됨

→ 3 direction briefs
Generate 4 variants of direction #1

Generate 4 images for: '<chosen prompt>'. Use Recraft for clean illustration style.✓ 복사됨

→ 4 URLs
Iterate

#2 is closest. Tweak: warmer palette, less cluttered background. Regenerate 3 more.✓ 복사됨

→ Refined set

결과: A distinctive hero image for roughly the cost of a coffee.

함정

Over-iterating burns credits fast — Cap yourself at 2 iteration rounds; if nothing clicks, the direction is wrong — reset the brief

조합

다른 MCP와 조합해 10배 효율

everart + filesystem

Generate then save locally for commit

Generate an OG card for my 'caching' post, download the URL to ./public/og/caching.png.✓ 복사됨

everart + notion

Generate an illustration and embed it directly in a Notion page

Generate a banner image for the 'Onboarding' page and append it as an image block at the top.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
generate_image	prompt: str, model?: str (default '207910310772879360'), image_count?: int (default 1)	The only tool — generate N images matching a prompt	1 EverArt credit per image

비용 및 제한

운영 비용

API 쿼터: Depends on your EverArt plan — usually measured in credits
호출당 토큰: Prompt text only (~100 tokens); generation time is the bottleneck
금액: Check everart.ai/pricing — typically cents per image
팁: Generate image_count: 4 in one call instead of 4 separate calls — same cost, faster iteration

보안

권한, 시크릿, 파급범위

자격 증명 저장: EVERART_API_KEY in env var

데이터 외부 송신: Prompts and images to everart.ai

Repo is in modelcontextprotocol/servers-archived — functional but no active maintenance. Consider fal.ai, Replicate MCPs, or an official vendor MCP for production.

문제 해결

자주 발생하는 오류와 해결

401 Unauthorized

EVERART_API_KEY missing or invalid. Re-create at everart.ai and set in your MCP client config.

확인: curl -H "Authorization: Bearer $EVERART_API_KEY" https://api.everart.ai/v1/models

Image URL expires after a day

Download immediately with the filesystem MCP — don't rely on the hosted URL long-term.

Generation timeouts

Large image_count values can exceed client timeouts. Request 2 at a time and loop.

대안

EverArt 다른 것과 비교

대안	언제 쓰나	단점/장점
Replicate MCP	You want broad model choice (FLUX, SDXL, hundreds of fine-tunes)	More setup, more powerful, pay-per-second pricing
fal.ai MCP	You need fast inference and streaming	Similar pricing; slightly fewer models than Replicate
OpenAI DALL-E via API	Already on OpenAI and want one bill	Stricter content filters; narrower style range
