Rules

LLM Proxy rules can monitor, flag, and block potentially dangerous commands in LLM responses.

To create a rule as an admin, click "Create new Proxy Rule" on https://app.mintmcp.com/llm.

LLM Proxy Dashboard

Fill in:

  • Tool Name Regex Pattern: The rule activates when the LLM generates a tool call with name matching the pattern.
  • Arguments (optional): Conditions on tool arguments that must be met for the tool to activate.

Then, set "Actions" to run when the rule activates.

  • If you do not set any actions, then the tool call will be "flagged" but not blocked. You can review flagged actions after they happen at https://app.mintmcp.com/llm/activity.
  • The "Change Response" action overwrites the tool call before it reaches the client. Use this to prevent potentially dangerous tool calls from running.
  • The "Slack Notification" action sends a Slack message to a specified channel whenever the rule activates.

Finally, click "Create Rule" to enable the rule.

You can always edit or delete rules after you create them.
