WHAT IT DOES

What apply_migration_patch does on DataFlow MCP Server

AI agents invoke apply_migration_patch to trigger actions in DataFlow MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why apply_migration_patch needs a policy

The name implies applying a migration patch to a database, which is an Execute-level operation (running a migration). It could also be Destructive if migrations drop or overwrite data. However, with no description available, confidence is lowered. Given the sibling tool 'bulk_apply_migrations' and the MongoDB context, this likely executes schema or data migrations, which can be irreversible.

From the tool's definition Tool name 'apply_migration_patch' and sibling tools 'bulk_apply_migrations', 'get_migration_status' suggest migration execution. Description is empty.
