THE RISK

Why mysql_multi_tenancy_performance_insights needs a policy

The tool appears to analyze and surface performance insights and recommendations for multi-tenant MySQL databases. This is consistent with the server's stated purpose of 'read-only queries, performance analysis, and server monitoring.' No write, execute, or destructive operations are implied. Confidence is moderate because the description is sparse and doesn't explicitly confirm read-only behavior.

From the tool's definition 'Insights and recommendations for multi-tenant databases' — purely analytical/advisory output with no indication of data modification

How to control mysql_multi_tenancy_performance_insights

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_multi_tenancy_performance_insights:

policy.json

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

mysql_multi_tenancy_performance_insights 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.
