  "jsonrpc": "2.0",

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Agent Browser:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pointer_info": {}
  }
}
```
