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

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

## Why uro_url_filtering is rated Low

Based on the tool name alone, URL filtering typically retrieves, processes, or categorizes URLs without modifying or deleting data. However, confidence is reduced due to the empty description and the broader pentesting context of the server. If this tool performs URL normalization, validation, or categorization, it would be a Read operation.

From the tool's own definition: "Tool name 'uro_url_filtering' suggests URL filtering/processing functionality. Description is empty, limiting definitive classification. 'uro' commonly refers to URL rewriting/filtering tools in security contexts."

## Use case

AI agents call uro_url_filtering to retrieve information from Hexstrike Ai 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 Hexstrike Ai:

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