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

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

## Why lighthouse is rated High

This tool triggers an external operation (Lighthouse audit) whose side effects depend on the target website argument. While it does not modify data or execute arbitrary code on the user's system, it runs a complex automated inspection process on remote targets that could be resource-intensive, potentially cause rate-limiting issues, or trigger security alerts on the target server.

From the tool's own definition: "'Run Lighthouse audit on a website' — Lighthouse is a tool that executes audits, which involves automated inspection and analysis of web pages, requiring the tool to fetch, render, and analyze remote content."

Risk signals: Accepts URL/endpoint input (url)

## Use case

AI agents invoke lighthouse to trigger actions in Mcp. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Mcp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "lighthouse": {
      "limits": [
        {
          "counter": "lighthouse_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## 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`
