WHAT IT DOES

What mysql_optimize_table does on Multi-Database MCP Server

AI agents invoke mysql_optimize_table to trigger actions in Multi-Database 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 mysql_optimize_table needs a policy

OPTIMIZE TABLE is a non-destructive maintenance operation that restructures/defragments a table to reclaim storage and improve performance. It does not delete or irreversibly overwrite user data, but it does execute an in-place table rebuild which can be a long-running operation with significant side effects (locking, I/O load).

From the tool's definition 'Optimize a table to reclaim storage and improve performance' — this is a maintenance operation that reorganizes table data and indexes in-place
