hydra_pause_download · Hydra Bridge MCP: Risk & Policy

WHAT IT DOES

What hydra_pause_download does on Hydra Bridge

AI agents invoke hydra_pause_download to trigger actions in Hydra Bridge. 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 hydra_pause_download needs a policy

Pausing a download is an external operation that affects the state of the Hydra Launcher application. It is not a simple read, nor does it delete or irreversibly destroy data. It falls under Execute as it triggers a state change in an external system (the download manager). The blast radius is low since pausing is easily reversible.

From the tool's definition 'Pause an active download' — triggers an external operation (pausing a running download process in Hydra Launcher)
