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

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

## Why createWebhook is rated Medium

Creating a webhook is a write operation that adds a new resource to the system. While webhooks themselves are configuration objects, they can be used to trigger external HTTP callbacks on events, which could have significant downstream effects if misconfigured. However, webhook creation itself is reversible (webhooks can be deleted), so it does not rise to Destructive level.

From the tool's own definition: "Tool description states 'Creates a webhook' with optional Id specification. The createWebhook operation creates a new resource (webhook) in FusionAuth, which is a reversible modification operation."

## Use case

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

## Recommended policy (PolicyLayer)

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

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