all instances of `chrome-devtools-mcp`. Set the `isolated` option to `true`
to use a temporary user data dir instead which will be cleared automatically after
the browser is closed.

## Known limitations

### Operating system sandboxes

Some MCP clients allow sandboxing the MCP server using macOS Seatbelt or Linux
containers. If sandboxes are enabled, `chrome-devtools-mcp` is not able to start
Chrome that requires permissions to create its own sandboxes. As a workaround,
either disable sandboxing for `chrome-devtools-mcp` in your MCP client or use
`--connect-url` to connect to a Chrome instance that you start manually outside
of the MCP client sandbox.
