Why mysql_innodb_metrics_analysis needs a policy

The tool performs metrics analysis and performance monitoring, which are read-only operations that retrieve and examine server metrics without modifying data or executing commands that could alter system state.

From the tool's definition Tool is named 'mysql_innodb_metrics_analysis' and described as 'Deep analysis of InnoDB metrics for performance tuning' - purely analytical/diagnostic in nature with no modification capability.

How to control mysql_innodb_metrics_analysis

PolicyLayer is an MCP gateway — it sits between your AI agents and Mysql, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_innodb_metrics_analysis:

policy.json

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

mysql_innodb_metrics_analysis is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Mysql — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
