WHAT IT DOES

What reject_request does on ServiceNow MCP Server

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

RISK

Why reject_request is rated Medium

This tool modifies the state of an approval request by rejecting it, which is a reversible action. While the rejection decision itself cannot be undone without re-submitting, the tool does not destroy data or delete records—it simply changes a request's status. This qualifies as Write category.

From the tool's definition Tool description states 'Reject a pending approval request' and requires 'WRITE_ENABLED=true', indicating it modifies approval request state.

RECOMMENDED RULE

The rule that runs reject_request safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ServiceNow MCP Server, 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.
