WHAT IT DOES

What browser_handle_dialog does on Amazon MQ MCP Server

AI agents invoke browser_handle_dialog to trigger actions in Amazon MQ MCP Server. 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 browser_handle_dialog needs a policy

The tool name implies browser automation (handling dialogs such as alerts, confirms, or prompts), which falls under Execute as it triggers external browser operations. However, the empty description significantly lowers confidence. Given the server context (Amazon MQ broker management), this tool may be part of a browser-based automation workflow.

From the tool's definition Tool name 'browser_handle_dialog' suggests browser automation/interaction with dialogs; description is empty and uninformative.
