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

      ],
      "_inferred": true
    }
  }
}

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

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "skills-skill-5": {

      ],
      "_inferred": true
    }
  }
}

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

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "skills-skill-5": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/sendaifun/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

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

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "skills-skill-5": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/sendaifun/skills",
        "~/.claude/skills/skills"
      ],
      "_inferred": true
    }
  }
}

Claude Desktop과 같은 형식. Windsurf 재시작 후 적용.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "skills-skill-5",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/sendaifun/skills",
        "~/.claude/skills/skills"
      ]
    }
  ]
}

Continue는 맵이 아닌 서버 오브젝트 배열 사용.

~/.config/zed/settings.json

{
  "context_servers": {
    "skills-skill-5": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/sendaifun/skills",
          "~/.claude/skills/skills"
        ]
      }
    }
  }
}

context_servers에 추가. 저장 시 Zed가 핫 리로드.

claude mcp add skills-skill-5 -- git clone https://github.com/sendaifun/skills ~/.claude/skills/skills

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

사용 사례

실전 활용법: skills

How to scaffold an Anchor program with Claude

👤 Solana developers starting a new on-chain program ⏱ ~60 min advanced

언제 쓸까: You need a new Anchor program and don't want to pattern-match from random GitHub repos.

사전 조건

Rust + Anchor CLI installed — rustup + cargo install --git https://github.com/coral-xyz/anchor anchor-cli
Skill cloned — git clone https://github.com/sendaifun/skills ~/.claude/skills/skills-sendai

흐름

State the program goal

Scaffold an Anchor program for a simple escrow: deposit SOL, release to seller on confirmation.✓ 복사됨

→ Program with accounts, instructions, and idiomatic Anchor attributes
Tests

Add TypeScript client tests using the Anchor test harness.✓ 복사됨

→ tests/ directory with typed client
Build and deploy to localnet

Build, deploy to localnet, and verify the escrow flow with a test transaction.✓ 복사됨

→ Successful local deploy

결과: A working Anchor program with tests.

함정

Missing account constraints — Insist on explicit constraints for every account; skill prompts Claude to enumerate them

함께 쓰기: filesystem

Mint and distribute an SPL token

👤 Builders launching a token for a dev/test use case ⏱ ~30 min intermediate

언제 쓸까: You need an SPL token script you actually trust.

흐름

Draft the mint script

Write a TypeScript script that creates an SPL token with 9 decimals and mints 1M to a treasury account.✓ 복사됨

→ Script using @solana/spl-token with proper PDAs
Airdrop helper

Add a function that airdrops to an array of recipients using associated token accounts.✓ 복사됨

→ ATA creation + transfer

결과: A reusable mint + distribute script.

함정

Forgetting ATA creation — Use getOrCreateAssociatedTokenAccount, not manual derivations

조합

다른 MCP와 조합해 10배 효율

skills-skill-5 + filesystem

Work across an Anchor monorepo

Read programs/, add a new program following the existing structure.✓ 복사됨

skills-skill-5 + github

Open PRs for contract changes with meaningful descriptions

Open a PR titled 'feat: escrow program' with tests.✓ 복사됨

도구

이 MCP가 노출하는 것

도구	입력	언제 호출
anchor-scaffolding	program intent	New program
spl-token-recipes	mint/transfer/airdrop intent	Token work
transaction-builder	list of instructions	Complex multi-ix flows

비용 및 제한

운영 비용

API 쿼터: none beyond RPC usage you configure
호출당 토큰: 5–15k per scaffold
금액: free at skill level; Solana fees are your own
팁: Develop on localnet/devnet; don't burn mainnet SOL for iteration

보안

권한, 시크릿, 파급범위

자격 증명 저장: never paste private keys into the prompt — use env vars and ephemeral devnet keys

데이터 외부 송신: your configured RPC only

절대 부여 금지: wallet signing from within a prompt

On-chain code is bearer-asset code: treat security review as mandatory before mainnet
Never ask the skill to work with a mainnet wallet that holds real value

문제 해결

자주 발생하는 오류와 해결

anchor build fails

Check Rust toolchain and Anchor CLI version; pin with rust-toolchain.toml.

확인: anchor --version && rustc --version

Account constraint errors at runtime

Re-ask Claude to enumerate constraints and PDAs explicitly
