Navigate preview pages and connect tools securely

Jump to a page inside your preview and manage how connected tools access Flex.

Go straight to the page you need

The preview toolbar now includes page navigation. Enter a path to open a different page inside the current preview, including a query string or an anchor when needed.

This makes it easier to review a particular screen without opening another tab or manually editing the preview’s full address.

Authorize connected tools in your browser

Flex adds browser-based authorization for MCP connections, with consent that you can revoke. Tool access is checked against the intended resource, and runtime GitHub access is restricted to the repositories a preview needs.

These changes give integrations a clearer authorization flow while tightening the boundaries around repository access.

More dependable startup

Orchestrators now restore their tenant identity before running startup network checks. This fixes a startup ordering problem that could interfere with reconnecting the infrastructure behind your previews.
