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

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

## Why create_webhook is rated High

A webhook that 'triggers collection with custom payload' causes active execution of a Postman collection when invoked. This is more than just writing a configuration record — it establishes an externally-triggerable execution endpoint.

From the tool's own definition: "Creates webhook that triggers collection with custom payload"

## Use case

AI agents invoke create_webhook to trigger actions in Postman. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_webhook": {
      "limits": [
        {
          "counter": "create_webhook_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
