validate_property

What validate_property does on ServiceNow-MCP

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

Why validate_property is rated Low

This is a read operation that checks conformance of a value to schema constraints. It retrieves/queries validation metadata and returns success/failure without creating, modifying, or deleting any data. The explicit 'without saving' clause rules out Write or Destructive categories. Severity is low because misuse causes only informational side effects (validation pass/fail), not data corruption or operational harm.

From the tool's definition Tool validates a property value against type constraints 'without saving'—no modification to data occurs. Description explicitly states validation only, no persistence.

The rule that runs validate_property safely

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

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