WHAT IT DOES

What mysql_query_stats does on Mysql Mcp

AI agents call mysql_query_stats to retrieve information from Mysql Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why mysql_query_stats is rated Low

The tool retrieves and returns aggregate query performance statistics from MySQL's built-in performance_schema database. It does not execute arbitrary SQL, modify data, delete anything, or move money. The explicit restriction against passing query strings confirms it performs read-only introspection. The blast radius of misuse is minimal—an agent could retrieve performance data but cannot alter system state.

From the tool's definition Tool description states 'Get top query statistics from performance_schema' and explicitly prohibits passing specific query or SQL strings.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs mysql_query_stats 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_query_stats, this is the rule to start with:

mysql_query_stats Allowed

mysql_query_stats is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "mysql_query_stats": {}
  }
}

ALLOW ONLY 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_query_stats call is checked against it from then on.
