open_deeplink · AVD MCP Server MCP: Risk & Policy

WHAT IT DOES

What open_deeplink does on AVD MCP Server

AI agents invoke open_deeplink to trigger actions in AVD 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 open_deeplink needs a policy

This tool executes an Android 'am start' command to open a deeplink URI, triggering an external operation (launching an activity/intent on the device). It runs a shell command whose effects depend on the URI argument provided, which could open arbitrary apps or web content.
