THE RISK

Low Risk

Why get_flow_logs needs a policy

This tool retrieves and queries existing flow execution logs from a ServiceNow instance without creating, modifying, or deleting data. It is a read-only operation with no side effects. The low severity reflects that log data exposure, while potentially sensitive, does not enable destructive or system-altering actions by the AI agent.

From the tool's definition Tool name 'get_flow_logs' and description 'Retrieve flow execution log entries' indicate data retrieval with no modification capability.

POLICY

How to control get_flow_logs

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

policy.json

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

get_flow_logs is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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