WHAT IT DOES

What monitor_create does on ReplyNodes

AI agents call monitor_create to retrieve information from ReplyNodes without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`body`	object	Yes
`Idempotency-Key`	string	Yes	header parameter

Parameters from the server's own tool schema.

RISK

Why monitor_create is rated Low

Even though monitor_create only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs monitor_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ReplyNodes, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For monitor_create, this is the rule to start with:

monitor_create Allowed

monitor_create is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "monitor_create": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect ReplyNodes, apply this rule, and every monitor_create call is checked against it from then on.
