generate_mock_webhook_event

THE RISK

High Risk

This tool generates and presumably triggers mock webhook events sent to a local endpoint, which constitutes executing an external operation (HTTP request to an endpoint). While it is for testing purposes, it actively sends data to an endpoint rather than just reading or writing static data.

HOW TO CONTROL GENERATE_MOCK_WEBHOOK_EVENT

PolicyLayer is an MCP gateway — it sits between your AI agents and PayRam MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for generate_mock_webhook_event:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "generate_mock_webhook_event": {
      "limits": [
        {
          "counter": "generate_mock_webhook_event_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

generate_mock_webhook_event stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register PayRam MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
