WHAT IT DOES

What connect_browser does on MCP Browser Logger

AI agents invoke connect_browser to trigger actions in MCP Browser Logger. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why connect_browser needs a policy

Establishing a DevTools Protocol connection to a browser grants the ability to monitor, inspect, and control browser behavior. This is an enabling action for subsequent Execute-level operations (e.g., evaluate_javascript, monitor network traffic). While the connection itself doesn't directly execute code, it triggers an external operation that opens a privileged control channel to the browser.
