WHAT IT DOES

What create_database does on Claude File Management Server

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

WHY IT NEEDS A POLICY

Why create_database needs a policy

Creating a new SQLite database is a write operation that creates new data structures. While reversible (the database can be deleted), it could impact system resources or create unexpected data stores if misused by an agent. It does not execute arbitrary code, delete existing data, or move money, so Write is the appropriate category rather than Execute or Destructive.

From the tool's definition Tool name 'create_database' with description 'Create a new SQLite database' indicates creation of a new data store, which is a reversible write operation.
