## Facts

- Tool: `regions`
- Server: 19hz (`https://gateway.pipeworx.io/19hz/mcp`) — https://policylayer.com/tools/io-github-pipeworx-io-19hz.md
- Homepage: https://github.com/pipeworx-io/mcp-19hz
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server CORS policy: *
- Server rate-limited: yes
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why regions is rated Low

This tool performs a simple data lookup returning a list of regions. There are no write, execute, destructive, or financial operations involved. The blast radius of misuse is minimal—an AI could at worst request the list repeatedly, but cannot modify, delete, or trigger external actions. This is a straightforward Read operation.

From the tool's own definition: "Tool name 'regions' and description 'List the regions 19hz covers' clearly indicates a retrieval operation with no side effects. The description explicitly states it returns data (slug + label) for use by other tools."

## Use case

AI agents call regions to retrieve information from 19hz 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 19hz:

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

## 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`
