        "mcp-remote",
        "https://api.skyll.app/mcp"
      ]
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

        "mcp-remote",
        "https://api.skyll.app/mcp"
      ]
    }
  }
}

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

VS Code → Cline → MCP Servers → Edit

  }
}

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

        "https://api.skyll.app/mcp"
      ]
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [

        "mcp-remote",
        "https://api.skyll.app/mcp"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

  "context_servers": {

          "https://api.skyll.app/mcp"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

사용 사례

실전 활용법: Skyll

Let Claude find the right skill mid-task, without you pre-installing

👤 Anyone running Claude Code or Claude Desktop with a shifting set of tasks ⏱ ~5 min beginner

언제 쓸까: You ask Claude to do something niche (generate invoices, migrate Redux to Zustand, do a legal review) and you don't know which skill exists for it.

사전 조건

Skyll MCP configured — Paste the config block above into your client's MCP settings — uses the hosted endpoint by default

흐름

Ask naturally

I need to produce an investor deck from a one-pager. Use Skyll to find a skill that does this, and apply it.✓ 복사됨

→ Agent calls search_skills, picks the best match (e.g. interactive-slides), and executes its instructions
Verify before running

Before applying, show me the top 3 Skyll matches with their relevance scores, so I can pick.✓ 복사됨

→ 3-row ranked list with short descriptions

결과: Agents reach for the right skill by name when it exists — you stop re-building wheels by hand.

함정

Low-quality skill ranks #1 because of keyword match — Require the agent to show top-3 + scores; pick manually on first use
Skill content is trusted blindly — Skyll returns SKILL.md; review it like any other prompt before granting tool access

함께 쓰기: filesystem

Browse and curate a personal skill library

👤 DevRel, team leads standardizing tools ⏱ ~30 min intermediate

언제 쓸까: You want to maintain an approved list of skills your team should use — not random ones pulled at runtime.

흐름

Explore the index

Using Skyll, show me every skill tagged 'code-review' with ≥50 stars. Group by use case.✓ 복사됨

→ Ranked groups: PR review / inline review / static-analysis review
Pick a short list

From that list, pick 3 you'd ship to a team of 10 engineers. Why each?✓ 복사됨

→ 3 picks with trade-off reasoning
Lock them in

Export the 3 SKILL.md files to /ops/approved-skills/ so our onboarding can use fixed versions.✓ 복사됨

→ 3 files on disk; version string captured

결과: Team gets a vetted, versioned skill set — no Wild West installs.

함정

Upstream skill updates break your workflow — Pin SHA/version when exporting; re-evaluate on a cadence, not automatically

함께 쓰기: filesystem

Give an autonomous agent skill-discovery as a first-class primitive

👤 Builders of long-running agents (OpenClaw, custom harnesses) ⏱ ~60 min advanced

언제 쓸까: Your agent takes multi-step jobs and shouldn't hit 'I don't know how' when the answer is a one-file skill away.

사전 조건

Agent harness that supports MCP — Most Anthropic-ecosystem agents already do

흐름

Add skill discovery to the planner

Update the planner: when a subtask has 'no matching local tool', call Skyll.search_skills first before giving up.✓ 복사됨

→ Planner gains a new branch: local tool → Skyll → web search
Cap the scope

Require every Skyll-fetched skill be reviewed by the supervisor agent before execution. Log the SKILL.md hash.✓ 복사됨

→ Audit trail of every runtime-discovered skill

결과: Agent gracefully expands its capability set without you pre-loading 500 skills.

함정

Prompt injection via skill content — Treat SKILL.md as untrusted input; sanitize or review before invoking; never auto-approve shell/write tools from a discovered skill

함께 쓰기: sequential-thinking

조합

다른 MCP와 조합해 10배 효율

skyll-skill + filesystem

Write discovered skills to ~/.claude/skills/ for persistent availability

Search Skyll for 'changelog generator'. If the top match is ≥80 score, save its content to ~/.claude/skills/changelog/SKILL.md.✓ 복사됨

skyll-skill + sequential-thinking

Multi-step plans that call Skyll only when local tools aren't enough

Plan the task; at each step, decide: local tool, Skyll skill, or web fetch. Execute.✓ 복사됨

skyll-skill + memory

Remember which Skyll-discovered skills actually worked for similar tasks

When a Skyll skill succeeds, save to memory under 'skills.working.<tag>'. Next time, prefer saved ones.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출	비용
search_skills	query: str, limit?: int	Primary — natural-language lookup over the skill index	free
get_skill	source: str, id: str	Fetch the full SKILL.md for a candidate you want to use	free
add_skill	name: str (or full path)	Shorthand: search + get in one call	free
get_cache_stats	none	Debug cold-lookup latency; mostly operational	free

비용 및 제한

운영 비용

API 쿼터: Hosted endpoint is free for reasonable use; self-host for heavy use
호출당 토큰: 200–2000 — Skyll returns focused content, not full repo dumps
금액: Free
팁: Self-host via pip install skyll when you're hammering search; hosted is fine for one-at-a-time use

보안

권한, 시크릿, 파급범위

자격 증명 저장: None for hosted use; self-host uses standard env vars

데이터 외부 송신: Queries go to api.skyll.app (hosted) — natural-language search text only

절대 부여 금지: Auto-execute shell commands from a Skyll-discovered SKILL.md without review

Skills discovered at runtime are effectively remote prompts. Prompt-injection and write-tool escalation risk is real. Always require human approval for discovered skills that request filesystem write or shell.
Pin skill versions (by SHA) for anything you ship to production; runtime lookup can surface updated content without notice.

문제 해결

자주 발생하는 오류와 해결

Top result looks irrelevant

Try a more specific query; the free-text index favors keyword-dense phrasing. 'extract PII from PDF files' beats 'handle privacy'.

확인: Compare score field across queries

Hosted endpoint slow

Self-host: pip install skyll && python -m src.mcp_server. Then point the MCP config at http://localhost:8080.

확인: Check tavily-free endpoint at https://api.skyll.app/health

mcp-remote: connection refused

mcp-remote needs the SSE URL reachable. Test with curl https://api.skyll.app/mcp/sse first.

확인: curl -v https://api.skyll.app/mcp/sse

대안

Skyll 다른 것과 비교

대안	언제 쓰나	단점/장점
awesome-claude-skills (list)	You want to browse skills by category, not query at runtime	Human-curated list — lower coverage, higher signal
pre-install every skill	You know your exact workflow and want deterministic behavior	Skill drift and token bloat if you install 100+ just-in-case
web search + filesystem write	You want a general web search, not skill-specific indexing	No relevance scoring against SKILL.md format; more hallucination risk
