WHAT IT DOES

What create_database_item does on Ncp

AI agents use create_database_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.

RISK

Why create_database_item is rated Medium

This tool creates new data reversibly in a Notion database. It is a Write operation because the action creates or modifies data without irreversibly deleting it and without executing arbitrary code. The severity is medium because misuse could clutter or pollute a Notion database with unwanted entries, but the impact is localized to a single database and entries can be manually deleted.

From the tool's definition create_database_item – creates a new item in a Notion database. The term 'create' indicates data is being added to a persistent external service (Notion).

Attacks that exploit this kind of access

RECOMMENDED RULE

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

create_database_item Rate-limited

create_database_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_database_item call is checked against it from then on.
