## Features

- Responsive design for mobile (480px), tablet (768px), desktop (1280px)
- i18n translations for 9 languages (zh/en/zh-TW/ja/ko/de/es/fr/pt)

## Technical Details
- Add raw parameter to fetchMcpTools API for unfiltered tools
- Pass raw parameter through controller → bridgeMcpAction → client
- Backend _mcp_tools_list supports raw_mode to skip include/exclude filter
- 28 MCP unit tests pass (23 controller + 5 bridge action)

- McpServerCard.vue: Add manage tools button
