WHY IT NEEDS A POLICY

Why mssql_bulk_insert needs a policy

This tool creates multiple new rows in a database, which is a reversible write operation. The 'bulk' nature increases the blast radius compared to single-row inserts, as an agent mistake could insert large volumes of incorrect data. However, it is not destructive (data remains recoverable via rollback or deletion) and not financial.

From the tool's definition Tool name 'mssql_bulk_insert' and description 'Insert multiple rows efficiently using bulk operations' explicitly indicate data creation/modification via bulk insertion.
