WHAT IT DOES

What complete_task does on NowAIKit — ServiceNow AI Toolkit

AI agents use complete_task 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 complete_task is rated Medium

This tool modifies task records by changing their status to complete, which is a reversible write operation. It does not delete data (would be Destructive), execute arbitrary code (would be Execute), or transfer funds (would be Financial). The medium severity reflects that an AI agent completing tasks incorrectly could cause workflow disruption, but the effect is reversible through task reopening or status changes.

From the tool's definition Tool description explicitly states 'Mark a task as complete' with requirement for WRITE_ENABLED=true, indicating data modification capability. The action updates task state in ServiceNow.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs complete_task 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 complete_task, this is the rule to start with:

complete_task Rate-limited

complete_task 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.
