WHAT IT DOES

What mysql_flush_tables does on Mysql Mcp

AI agents invoke mysql_flush_tables to trigger actions in Mysql Mcp. 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_flush_tables is rated High

FLUSH TABLES in MySQL is an administrative operation that closes all open tables, flushes the query cache, and can acquire global read locks. It affects server-wide state and running queries, potentially causing disruptions to active connections and operations.

RECOMMENDED RULE

The rule that runs mysql_flush_tables safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_flush_tables, this is the rule to start with:

mysql_flush_tables Rate-limited

mysql_flush_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.

          "counter": "mysql_flush_tables_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_flush_tables call is checked against it from then on.
