What create_item does on Ncp
AI agents use create_item to create or update resources in Ncp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ncp environment.
Why create_item is rated Medium
This tool creates new data (a Monday.com item/task) which is a reversible write operation. It does not delete, execute arbitrary code, or move money. The severity is medium due to potential impact on project data and workflows if misused by an AI agent, but the effect is limited to a single item creation and is reversible.
From the tool's definition Tool name 'create_item' combined with description 'Create Monday.com item' indicates creation of new data in Monday.com project management platform.
Attacks that exploit this kind of access
The rule that runs create_item safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_item, this is the rule to start with:
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.
The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every create_item call is checked against it from then on.

create_item is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_item rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_item. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
