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

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

## Why set_hostname is rated Medium

This tool modifies device configuration by setting a hostname alias, which is a reversible change. It does not delete data (not Destructive), execute arbitrary code (not Execute), or involve financial transactions (not Financial).

From the tool's own definition: "Tool name 'set_hostname' and description 'Set the hostname alias on a device' indicate modification of device configuration."

## Use case

AI agents use set_hostname to create or update resources in API-Central, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your API-Central environment.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "set_hostname": {
      "limits": [
        {
          "counter": "set_hostname_rate",
          "window": "minute",
          "max": 30,
          "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`
