## Appendix: Test Evidence

### Command Help Output
```
Usage: cli uninstall [OPTIONS]

  🗑️ Remove MCP Browser configuration from Claude Code/Desktop.

  Removes the mcp-browser configuration from Claude Code or Claude Desktop
  MCP server settings. This does not uninstall the package itself.

  Examples:
    mcp-browser uninstall                         # Remove from Claude Code
    mcp-browser uninstall --target claude-desktop # Remove from Claude Desktop
    mcp-browser uninstall --target both           # Remove from both

  Configuration locations:
    Claude Code:    ~/.claude/settings.local.json
    Claude Desktop: OS-specific location
      • macOS:   ~/Library/Application Support/Claude/
      • Linux:   ~/.config/Claude/
      • Windows: %APPDATA%/Claude/

  After uninstallation:
    1. Restart Claude Code or Claude Desktop
    2. The 'mcp-browser' MCP server will no longer be available
    3. To uninstall the package itself, use: pip uninstall mcp-browser

Options:
  --target [claude-code|claude-desktop|both]
                                  Target to uninstall from (default: claude-
                                  code)
  -h, --help                      Show this message and exit.
```
