AI agents call mysql_drop_index to permanently remove resources in Mcp Windows — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Dropping an index is a destructive action that irreversibly removes database metadata and cannot be automatically recovered. While not as severe as dropping an entire table, it degrades query performance and requires manual intervention to restore. An AI agent could accidentally degrade system performance or availability by dropping critical indexes without understanding their purpose.
From the tool's definition Tool name 'mysql_drop_index' explicitly performs a DROP operation on a database index. The verb 'drop' is irreversible—once an index is deleted, it cannot be undone without recreating it from scratch.
Documented attack patterns abuse exactly the kind of access mysql_drop_index 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_drop_index:
{
"version": "1",
"default": "deny",
"hide": [
"mysql_drop_index"
]
}mysql_drop_index disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Drop an index from a table. It is categorised as a Destructive tool in the Mcp Windows MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Windows MCP server in PolicyLayer and add a rule for mysql_drop_index: 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_drop_index is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the mysql_drop_index 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_drop_index. 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_drop_index 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.
