WHAT IT DOES

What browser_handle_dialog does on CoWork OS

AI agents invoke browser_handle_dialog to trigger actions in CoWork OS. 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.

RISK

Why browser_handle_dialog is rated High

This tool performs browser automation actions (accepting or dismissing JS dialogs), which are external operations that interact with a running browser session. The effects depend on the dialog context and could unblock or cancel sensitive operations. This falls under Execute as it triggers browser-side behavior.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs browser_handle_dialog safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For browser_handle_dialog, this is the rule to start with:

browser_handle_dialog Rate-limited

browser_handle_dialog stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
