create-item · Itemit MCP: Risk & Policy

WHAT IT DOES

What create-item does on Itemit

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

WHY IT NEEDS A POLICY

Why create-item needs a policy

This tool creates new data entries in the asset management system. It is reversible (items can be deleted or modified later), so it falls under Write rather than Destructive. The severity is medium because misuse could pollute the asset database with false records, but the impact is limited to asset metadata without financial or system-level consequences.

From the tool's definition Tool description states 'Create an item in Itemit' with parameters name, description, and serial. The create action modifies the asset database by adding new records.

Verdict

create-item Rate-limited

create-item 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.
