bulk_add_rows · Notion MCP: Risk & Policy

WHAT IT DOES

What bulk_add_rows does on Notion

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

WHY IT NEEDS A POLICY

Why bulk_add_rows needs a policy

This tool creates multiple database records in Notion, which is a reversible modification. It does not delete, execute arbitrary code, move money, or retrieve data. Severity is medium because bulk operations can affect many records, but the action is reversible and limited in scope to database row creation without executing code or destructive actions.

From the tool's definition Tool description states 'Add multiple rows to a database at once' — a write operation that creates data in Notion. The verb 'add' and 'rows' confirm data creation rather than retrieval or destruction.
