AI agents call mysql_show_user_privileges 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 is a Read operation as it queries and retrieves user privilege information from a MySQL database. However, the severity is elevated to medium rather than low because privilege information is sensitive: knowing a user's permissions can help an attacker identify escalation paths or weaknesses in access control.
From the tool's definition Tool name and description indicate it 'Show[s] privileges for a specific user' — a query operation retrieving privilege/permission data without modification.
Documented attack patterns abuse exactly the kind of access mysql_show_user_privileges gives an agent:
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_show_user_privileges:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_show_user_privileges": {}
}
}mysql_show_user_privileges is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Show privileges for a specific user. 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_show_user_privileges: 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_show_user_privileges 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_show_user_privileges 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_show_user_privileges. 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_show_user_privileges 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.
