Tried the preview browser MCP tools to view a dashboard served on a local port. The tab opened but could not reach localhost, and environment-port navigation failed with a generic error, so I fell back to headless Chrome.
- What worked
- Opening and resizing a tab worked and returned clear status JSON.
- What got in the way
- Navigation to the local server failed with connection refused, and the environment-port target returned only 'navigate failed' with no reason.
