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

{
  "mcpServers": {
    "lessie-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/LessieAI/lessie-skill",
        "~/.claude/skills/lessie-skill"
      ],
      "_inferred": true
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "lessie-skill": {
      "command": "git",
      "args": [
        "clone",

      ],
      "_inferred": true
    }
  }
}

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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "lessie-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/LessieAI/lessie-skill",
        "~/.claude/skills/lessie-skill"
      ],
      "_inferred": true
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "lessie-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/LessieAI/lessie-skill",
        "~/.claude/skills/lessie-skill"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "lessie-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/LessieAI/lessie-skill",
        "~/.claude/skills/lessie-skill"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "lessie-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/LessieAI/lessie-skill",
          "~/.claude/skills/lessie-skill"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add lessie-skill -- git clone https://github.com/LessieAI/lessie-skill ~/.claude/skills/lessie-skill

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

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
find-people	title / company / domain / location filters	Starting from ICP filters	Lessie plan-dependent
enrich-contact	person id or profile	Shortlist narrowed and ready to contact	Per-enrichment credit
find-company	company name or domain + optional filters	Account research before outreach	Plan-dependent
send-email	Gmail/Outlook account + to/subject/body	Only after you review drafts — don't auto-send at scale	Uses your own mailbox

비용 및 제한

운영 비용

API 쿼터: Depends on Lessie plan — the skill itself is just the prompt wrapper
호출당 토큰: Moderate; responses can be large when listing 50+ contacts
금액: Free — skills are local files. Lessie's data API is paid; consult current plans.
팁: Filter aggressively before enrichment; every enrichment call costs credits.

보안

권한, 시크릿, 파급범위

자격 증명 저장: Lessie API key in env var; Gmail/Outlook via OAuth if you use send-email

데이터 외부 송신: Queries go to Lessie's API. Email sending goes via your provider.

Contact enrichment must comply with GDPR / CAN-SPAM / local laws — Lessie provides data, compliance is on you.
Don't automate bulk sends without warming; volume without domain reputation = spam folder.

문제 해결

자주 발생하는 오류와 해결

Skill not invoked — Claude offers generic LinkedIn advice

Say 'use lessie-skill' explicitly.

확인: ls ~/.claude/skills/lessie-skill/SKILL.md

SKILL.md frontmatter wrong

Re-clone; description drives activation.

확인: head ~/.claude/skills/lessie-skill/SKILL.md

Wrong trigger keywords — enrichment runs before filtering narrows the list

Explicitly: 'first find-people, then I'll pick who to enrich'.

대안

lessie-skill 다른 것과 비교

대안	언제 쓰나	단점/장점
Apollo.io / Clay	You want a full GTM suite with sequencing tools	Much heavier platforms; pricier
LinkedIn Sales Navigator	LinkedIn-native prospecting with InMail	Expensive, no agent integration
