AI agents call mysql_drop_primary_key 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.
This tool performs an irreversible schema modification that destroys a database constraint. While data rows remain, the removal of a primary key constraint is a destructive database operation that impacts data integrity enforcement and cannot be simply reversed without manual intervention.
From the tool's definition Tool name explicitly states 'drop_primary_key' and description confirms it removes the primary key constraint from a table. The DROP operation is irreversible and modifies database schema in a way that cannot be easily undone.
Documented attack patterns abuse exactly the kind of access mysql_drop_primary_key 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_primary_key:
{
"version": "1",
"default": "deny",
"hide": [
"mysql_drop_primary_key"
]
}mysql_drop_primary_key disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Drop the primary key 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_primary_key: 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_primary_key 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_primary_key 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_primary_key. 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_primary_key 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.
