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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why util_links_extract is rated Low

This tool extracts and analyzes link information from a page—a passive read operation. It retrieves metadata about page structure (links) without creating, modifying, deleting, or executing any actions. The use case (crawling, routing, inspection) is observational. No financial, destructive, or code execution capability is implied.

From the tool's own definition: "Tool description states 'Map internal and external links on a page for crawling, routing, and site inspection.' The verb 'map' combined with 'for crawling' and 'inspection' indicates data retrieval and analysis with no modification or side effects."

Risk signals: Accepts URL/endpoint input (url)

## Use case

AI agents call util_links_extract to retrieve information from Delx 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 Delx MCP Server:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
