Known Issues

MCP Servers Not Auto-Loading

Issue: The bundled MCP servers (Playwright and Context7) may not load automatically when the plugin is installed.

Workaround: Manually add them to your project's .claude/settings.json:

{
  "mcpServers": {
    "playwright": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@playwright/mcp@latest"],
      "env": {}
    },
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Or add them globally in ~/.claude/settings.json for all projects.
