ira_hover · IRA-RESEARCHER MCP: Risk & Policy

WHAT IT DOES

What ira_hover does on IRA-RESEARCHER

AI agents invoke ira_hover to trigger actions in IRA-RESEARCHER. 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 ira_hover needs a policy

Hovering is a browser action that triggers external UI operations such as revealing tooltips, dropdown menus, or JavaScript event handlers. It is an Execute-category action because its effects depend on the target element and page context. Severity is low since hovering alone rarely causes irreversible harm, but it can trigger scripts or reveal hidden UI elements that lead to further actions.

From the tool's definition Hover over an element — triggers a browser interaction (mouseover/hover) on a DOM element

Verdict

ira_hover Rate-limited

ira_hover 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.
