Get the current database schema showing all loaded tables
AI agents call get_database_schema to retrieve information from Mcp Csv Database without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns metadata about the database structure. It has no side effects, cannot modify data, and poses minimal risk if misused by an AI agent. It falls squarely into the Read category as a data retrieval operation.
