Provide index usage statistics and suggestions for optimization.
AI agents call mysql_index_usage_statistics to retrieve information from Mysql without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reports performance analysis data (index usage statistics) without creating, modifying, deleting, or executing arbitrary operations. It is a read-only monitoring/analysis function aligned with the server's stated purpose of 'performance analysis and server monitoring.' The sibling tool 'analyze_index_usage' reinforces that this server provides read-only analysis capabilities.
From the tool's definition Tool name contains 'statistics' and description states 'Provide index usage statistics and suggestions for optimization' - these are purely informational queries about database performance metrics with no data modification or deletion.
Documented attack patterns abuse exactly the kind of access mysql_index_usage_statistics gives an agent:
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_index_usage_statistics:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_index_usage_statistics": {}
}
}mysql_index_usage_statistics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Provide index usage statistics and suggestions for optimization. It is categorised as a Read tool in the Mysql MCP Server, which means it retrieves data without modifying state.
Register the Mysql MCP server in PolicyLayer and add a rule for mysql_index_usage_statistics: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Mysql. Nothing to install.
mysql_index_usage_statistics is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mysql_index_usage_statistics rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for mysql_index_usage_statistics. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mysql_index_usage_statistics is provided by the Mysql MCP server (mukul975/mysql-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mysql, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
