What restore_database does on Follow Plan MCP Server

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

WHY IT NEEDS A POLICY

Why restore_database needs a policy

The restore_database tool modifies data by replacing the current database with a backup version. This is categorized as Write rather than Destructive because: (1) the operation is theoretically reversible (the overwritten state could be backed up again), (2) data is not permanently deleted but replaced with a previous version, and (3) the tool provides recovery functionality.

From the tool's definition Tool name 'restore_database' with description 'Restore database from backup' indicates overwriting the current database state with backed-up data.
