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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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": {
    "reddit-mcp-buddy-2": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  }
}

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

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "reddit-mcp-buddy-2",
      "command": "TODO",
      "args": [
        "See README: https://github.com/karanb192/reddit-mcp-buddy"
      ]
    }
  ]
}

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": {
    "reddit-mcp-buddy-2": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/karanb192/reddit-mcp-buddy"
        ]
      }
    }
  }
}

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

claude mcp add reddit-mcp-buddy-2 -- TODO 'See README: https://github.com/karanb192/reddit-mcp-buddy'

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