Ends recurring revenue permanently

Part of the Stripe MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents may call cancel_subscription to permanently remove or destroy resources in Stripe. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.

// WHY ENFORCE A POLICY ON CANCEL_SUBSCRIPTION

Without a policy, an AI agent could call cancel_subscription in a loop, permanently destroying resources in Stripe. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.

// RECOMMENDED POLICY

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

stripe.yaml

tools:
  cancel_subscription:
    rules:
      - action: deny
        reason: "Blocked by default — enable with approval"
