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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "ocr_image",
    "arguments": {}
  }
}
```

## Why ocr_image is rated Low

OCR (Optical Character Recognition) is a data retrieval operation that analyzes image content and extracts text. It has no side effects, does not modify any state, and does not execute external commands or code.

From the tool's own definition: "Tool performs 'OCR image recognition' - extracts text from images without modifying, deleting, or executing operations. The description and name indicate a read-only recognition operation."

## Use case

AI agents call ocr_image to retrieve information from NapCat 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 NapCat MCP Server:

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