WHAT IT DOES

What element_hover does on Mcp Anything

AI agents invoke element_hover to trigger actions in Mcp Anything. 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 element_hover is rated High

This tool triggers a browser/UI interaction (mouseover event) on an element, which is an external operation that executes an action in a UI context. Hovering can trigger side effects like dropdown menus appearing, tooltips, or JavaScript event handlers firing. This falls under Execute as it performs a browser action whose effects depend on which element is targeted.

RECOMMENDED RULE

The rule that runs element_hover safely

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

element_hover Rate-limited

element_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.
