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

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

## Why set_webhook is rated Medium

This tool writes configuration data (webhook URLs) that affects system behavior going forward. While not immediately destructive or financial, misconfiguration could redirect sensitive financial notifications to malicious endpoints, making it a write-level risk in a financial infrastructure context.

From the tool's own definition: "set_webhook creates and modifies webhook configurations, which are persistent configurations that trigger external notifications. The tool enables creating new notification endpoints or modifying existing ones."

## Use case

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

## Recommended policy (PolicyLayer)

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

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