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

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

  "params": {
    "name": "schedule_appointment",
    "arguments": {}

## Why schedule_appointment is rated Medium

This tool creates and persists new data records (appointments) in a database in a reversible manner—appointments can be updated or deleted later. This qualifies as Write rather than Execute (which would involve running arbitrary code) or Read (which retrieves without modification).

From the tool's own definition: "Tool name 'schedule_appointment' and server description indicate the tool creates new appointment records in a PostgreSQL database."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "schedule_appointment": {
      "limits": [
        {
          "counter": "schedule_appointment_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
```
