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

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

## Why hwpx_extract_json is rated Low

This tool performs data extraction and querying of HWPX documents—a read-only operation with no side effects. While it processes document data, it neither creates, modifies, executes commands, nor deletes anything. The masking feature actually reduces risk by redacting sensitive information during extraction. Classification is Read with low severity due to limited blast radius if misused by an AI agent.

From the tool's own definition: "Tool name contains 'extract' and description states 'extracts structured JSON from HWPX payload or URL'. The operation retrieves/parses document content without modifying it. Default behavior includes PII masking for safety."

## Use case

AI agents call hwpx_extract_json to retrieve information from Hwpx 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 Hwpx:

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