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

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

## Why security_headers_check is rated Low

This tool performs security header analysis against best practices without modifying systems, executing code, or triggering external operations. It retrieves and analyzes header data from a target web server to identify misconfigurations. No irreversible changes, code execution, financial impact, or destructive actions are implied. This is a standard security audit Read operation.

From the tool's own definition: "Tool description states it 'Check[s] HTTP security headers configuration' — a passive inspection operation with no modification, execution, or side effects. The verb 'check' and context of 'configuration' review indicate read-only analysis."

## Use case

AI agents call security_headers_check to retrieve information from Kali Linux 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 Kali Linux MCP Server:

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

## 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`
