WHAT IT DOES

What notion_create_database_item does on Notion MCP Server

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

WHY IT NEEDS A POLICY

Why notion_create_database_item needs a policy

This tool creates new data (a database item/page) in Notion, which is reversible (the item can be deleted later). This fits the Write category. Severity is medium because creating unauthorized database entries could pollute a user's workspace and potentially trigger downstream automation (e.g., notion_create_workflow), but the impact is limited compared to destructive or financial operations.

From the tool's definition Tool description states 'Create a new item (page) in a Notion database' — this is an explicit create operation that adds new data to a user's Notion workspace.
