インストール

クライアントを選択

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

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

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

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

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

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 サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

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

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

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

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

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

context_servers に追加。保存時に Zed がホットリロード。

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

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： skills

How to scaffold an Anchor program with Claude

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

使うタイミング： You need a new Anchor program and don't want to pattern-match from random GitHub repos.

前提条件

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

フロー

State the program goal

Scaffold an Anchor program for a simple escrow: deposit SOL, release to seller on confirmation.✓ コピーしました

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

Add TypeScript client tests using the Anchor test harness.✓ コピーしました

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

Build, deploy to localnet, and verify the escrow flow with a test transaction.✓ コピーしました

→ Successful local deploy

結果： A working Anchor program with tests.

注意点

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

組み合わせ： filesystem

Mint and distribute an SPL token

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

使うタイミング： You need an SPL token script you actually trust.

フロー

Draft the mint script

Write a TypeScript script that creates an SPL token with 9 decimals and mints 1M to a treasury account.✓ コピーしました

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

Add a function that airdrops to an array of recipients using associated token accounts.✓ コピーしました

→ ATA creation + transfer

結果： A reusable mint + distribute script.

注意点

Forgetting ATA creation — Use getOrCreateAssociatedTokenAccount, not manual derivations

組み合わせ

他のMCPと組み合わせて10倍の力を

skills-skill-5 + filesystem

Work across an Anchor monorepo

Read programs/, add a new program following the existing structure.✓ コピーしました

skills-skill-5 + github

Open PRs for contract changes with meaningful descriptions

Open a PR titled 'feat: escrow program' with tests.✓ コピーしました

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング
anchor-scaffolding	program intent	New program
spl-token-recipes	mint/transfer/airdrop intent	Token work
transaction-builder	list of instructions	Complex multi-ix flows

コストと制限

運用コスト

APIクォータ: none beyond RPC usage you configure
呼び出しあたりのトークン: 5–15k per scaffold
金額: free at skill level; Solana fees are your own
ヒント: Develop on localnet/devnet; don't burn mainnet SOL for iteration

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： never paste private keys into the prompt — use env vars and ephemeral devnet keys

データ送信先： your configured RPC only

絶対に付与しない： 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

トラブルシューティング

よくあるエラーと対処法

anchor build fails

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

確認： anchor --version && rustc --version

Account constraint errors at runtime

Re-ask Claude to enumerate constraints and PDAs explicitly
