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

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

## Why describe_image_file is rated Low

The tool reads image data from a local file and returns descriptive analysis via the Grok API. There are no side effects, no data modification, no code execution, and no destructive operations. This is purely informational retrieval, fitting the 'Read' category with low severity due to its limited blast radius—an AI misuse would at worst analyze unintended images, with no irreversible consequences.

From the tool's own definition: "Tool performs 'Analyze local image file and provide AI-generated description' — a read-only operation that retrieves visual information from an image without modifying, deleting, or executing code."

## Use case

AI agents call describe_image_file to retrieve information from Image Description 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 Image Description MCP Server:

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