What mysql_force_index does on Mysql Mcp
AI agents call mysql_force_index to permanently remove resources in Mysql Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why mysql_force_index is rated Critical
An AI agent that decides to call mysql_force_index doesn't hesitate, doesn't double-check, and doesn't stop at one. Whatever it removes from Mysql Mcp is gone. There is no undo for destructive operations.
Attacks that exploit this kind of access
The rule that runs mysql_force_index safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mysql Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mysql_force_index, this is the rule to start with:
mysql_force_index is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Mysql Mcp, apply this rule, and every mysql_force_index call is checked against it from then on.

mysql_force_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_force_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_force_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.
