WHAT IT DOES

What reject_request does on NowAIKit — ServiceNow AI Toolkit

AI agents use reject_request to create or update resources in NowAIKit — ServiceNow AI Toolkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your NowAIKit — ServiceNow AI Toolkit environment.

RISK

Why reject_request is rated Medium

This tool creates or modifies data reversibly—it changes an approval request's status, which could potentially be reversed through system administration or approval workflows. While consequential (rejecting a request can impact business processes), it is not destructive (the original request record remains) nor financial.

From the tool's definition Tool description states 'Reject a pending approval request' which modifies the state of an approval request from pending to rejected. The requirement flag 'WRITE_ENABLED=true' confirms this performs write operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs reject_request safely

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

reject_request Rate-limited

reject_request stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
