What browser_hover does on Amazon Location Service MCP Server

AI agents invoke browser_hover to trigger actions in Amazon Location Service 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.

High Risk

Why browser_hover needs a policy

The name 'browser_hover' implies triggering a browser UI action (mouse hover), which falls under Execute as it performs an external operation. However, the empty description significantly reduces confidence. The tool seems out of place on an Amazon Location Service MCP server, raising questions about its actual function.

From the tool's definition Tool name 'browser_hover' suggests a browser interaction action (hovering over an element), but the description is empty and uninformative.

Documented attack patterns abuse exactly the kind of access browser_hover gives an agent:

How to control browser_hover

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Location Service MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_hover:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "browser_hover": {
      "limits": [
        {
          "counter": "browser_hover_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

browser_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.

  1. Create a free account and register Amazon Location Service MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
