## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why get_display_info is rated Low

This tool queries and returns display/monitor metadata (resolution, DPI, monitor count). It performs no modifications, executions, deletions, or financial operations. It is purely informational retrieval with no blast radius if misused by an AI agent—it cannot alter system state or data.

From the tool's own definition: "Tool name 'get_display_info' and description 'Get display/monitor information: resolution, DPI, number of monitors' indicate a read-only operation that retrieves system display configuration data without modification, execution, or side effects."

## Use case

AI agents call get_display_info to retrieve information from Desktop Commander MCP Server 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 Desktop Commander MCP Server:

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