WHY IT NEEDS A POLICY

Why add_database_row needs a policy

This tool creates new structured data (a database row) in Notion. While the operation is reversible (rows can be deleted), it modifies the user's data permanently until explicitly removed. It does not execute arbitrary code, delete data irreversibly, or handle financial transactions.

From the tool's definition Tool name 'add_database_row' and description 'Add a new row to a database' indicate creation of new data in a Notion database, which is a reversible write operation.
