WHAT IT DOES

What pointer_info does on Agent Browser

AI agents call pointer_info to retrieve information from Agent Browser without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why pointer_info is rated Low

This tool only reads and reports environmental data (mouse cursor position and screen dimensions). It has no side effects, cannot modify state, execute code, or trigger external operations. It is purely informational, making it a Read category tool with low severity since misuse would only reveal harmless desktop metrics.

From the tool's definition Tool name 'pointer_info' and description 'Report the current desktop mouse position and primary screen size' indicate a query operation that retrieves positional and display information without modifying or executing anything.

RECOMMENDED RULE

The rule that runs pointer_info safely

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

pointer_info Allowed

pointer_info is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "pointer_info": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Agent Browser, apply this rule, and every pointer_info call is checked against it from then on.
