WHAT IT DOES

What mysql_lock_tables does on Mcp Windows

AI agents invoke mysql_lock_tables to trigger actions in Mcp Windows. 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.

RISK

Why mysql_lock_tables is rated High

Locking tables is an operational action that affects concurrent database access for all other sessions. While it doesn't permanently delete data, it can cause application-wide blocking, deadlocks, or denial-of-service conditions if misused.

From the tool's definition 'Lock tables for the current session' — acquires database-level locks that block other sessions from reading or writing the affected tables

mysql_lock_tables Rate-limited

mysql_lock_tables stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
