AI agents call mysql_table_size 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.
The tool performs a data retrieval operation to query table metadata (storage size). It has no side effects, does not modify or delete data, and does not execute arbitrary commands. This clearly falls under the Read category for database query operations. Severity is low because misuse would only expose database metadata, not cause system damage or data loss.
From the tool's definition Tool name and description indicate it retrieves storage size information for a table ('Get storage size information for a table').
Documented attack patterns abuse exactly the kind of access mysql_table_size 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_table_size:
{
"version": "1",
"default": "deny",
"tools": {
"mysql_table_size": {}
}
}mysql_table_size is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get storage size information for a table. 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_table_size: 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_table_size 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_table_size 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_table_size. 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_table_size 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.
