Установка

Выберите клиент

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

{
  "mcpServers": {
    "excalidraw-diagram-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/coleam00/excalidraw-diagram-skill",
        "~/.claude/skills/excalidraw-diagram-skill"
      ],
      "_inferred": true
    }
  }
}

Откройте Claude Desktop → Settings → Developer → Edit Config. Перезапустите после сохранения.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "excalidraw-diagram-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/coleam00/excalidraw-diagram-skill",
        "~/.claude/skills/excalidraw-diagram-skill"
      ],
      "_inferred": true
    }
  }
}

Cursor использует ту же схему mcpServers, что и Claude Desktop. Конфиг проекта приоритетнее глобального.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "excalidraw-diagram-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/coleam00/excalidraw-diagram-skill",
        "~/.claude/skills/excalidraw-diagram-skill"
      ],
      "_inferred": true
    }
  }
}

Щёлкните значок MCP Servers на боковой панели Cline, затем "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "excalidraw-diagram-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/coleam00/excalidraw-diagram-skill",
        "~/.claude/skills/excalidraw-diagram-skill"
      ],
      "_inferred": true
    }
  }
}

Тот же формат, что и Claude Desktop. Перезапустите Windsurf для применения.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "excalidraw-diagram-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/coleam00/excalidraw-diagram-skill",
        "~/.claude/skills/excalidraw-diagram-skill"
      ]
    }
  ]
}

Continue использует массив объектов серверов, а не map.

~/.config/zed/settings.json

{
  "context_servers": {
    "excalidraw-diagram-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/coleam00/excalidraw-diagram-skill",
          "~/.claude/skills/excalidraw-diagram-skill"
        ]
      }
    }
  }
}

Добавьте в context_servers. Zed перезагружается автоматически.

claude mcp add excalidraw-diagram-skill -- git clone https://github.com/coleam00/excalidraw-diagram-skill ~/.claude/skills/excalidraw-diagram-skill

Однострочная команда. Проверить: claude mcp list. Удалить: claude mcp remove.

Сценарии использования

Реальные сценарии: Excalidraw Diagram Skill

Generate an editable architecture diagram from a description

👤 Engineers documenting systems ⏱ ~15 min intermediate

Когда использовать: You want a diagram you can iterate on, not a static PNG.

Предварительные требования

Server/skill installed and authenticated — See repo README

Поток

Describe the system

Using the Excalidraw skill, draw our auth flow: SPA → API gateway → auth-service → Postgres → emit event to Kafka.✓ Скопировано

→ A .excalidraw file with labeled boxes + arrows
Iterate

Add a Redis cache between API gateway and auth-service.✓ Скопировано

→ Updated file with the new node + correct re-routed arrows

Итог: A diagram you actually edit, not redraw.

Подводные камни

For very large diagrams (>30 nodes) auto-layout struggles — For very large diagrams (>30 nodes) auto-layout struggles — split into multiple diagrams or group by concern.

Стоимость и лимиты

Во что обходится

Квота API: See provider docs for rate limits
Токенов на вызов: Varies by tool
Деньги: See repo README for pricing details
Совет: Cache tool results and avoid repeated identical calls.

Безопасность

Права, секреты, радиус поражения

Хранение учётных данных: Use environment variables; never commit secrets

Исходящий трафик: Tool calls go to the provider's API as documented

Устранение неполадок

Частые ошибки и исправления

file doesn't open in Excalidraw

Make sure the file ends with .excalidraw and is valid JSON. The skill outputs both, but check the extension.

Проверить: Open at excalidraw.com → load file

arrows pointing wrong way

Excalidraw's arrow startBinding/endBinding matters. The skill's templates handle it, but custom edits can break it.

Проверить: Reload the file

Альтернативы

Альтернатива	Когда использовать	Компромисс
BV-Venky/excalidraw-architect-mcp	You want it as an MCP server instead of a skill	MCP is heavier setup; skill is just a folder
