AI agents call mysql_query_cache_stats to retrieve information from Mcp Windows without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns statistics about MySQL query caching—a read-only operation that retrieves system information with no side effects, data modification, or code execution. The low severity reflects minimal risk even if accessed by an unauthorized agent, as it only exposes performance telemetry.
From the tool's definition Tool name 'mysql_query_cache_stats' and description 'Show query cache statistics' indicate retrieval and display of existing performance metrics without modification or execution of code.

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Windows, and nothing reaches the server without passing your rules. This is the rule we recommend for mysql_query_cache_stats:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_query_cache_stats": {}
}
}mysql_query_cache_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show query cache statistics. It is categorised as a Read tool in the Mcp Windows MCP Server, which means it retrieves data without modifying state.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for mysql_query_cache_stats: 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 Mcp Windows. Nothing to install.
mysql_query_cache_stats 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_query_cache_stats 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_query_cache_stats. 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_query_cache_stats is provided by the Mcp Windows MCP server (mukul975/mcp-windows-automation). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
