Automate refund workflows

Create a Mastra agent that calls `refund_order` when a customer triggers a specific support request. You can chain this with notification tools to keep your team in the loop. This MCP server provides the direct access needed to execute financial actions safely. You build the logic, the agent executes the steps.

Handle subscription lifecycle

Use `cancel_subscription` and `update_subscription_item` within your Mastra workflows to manage customer churn automatically. Define your own logic for when these actions trigger. Your agents handle the nuance of subscription management. No more manual updates in the dashboard for routine account tasks.

Sync usage records automatically

Call `create_usage_record` based on your internal system events to keep billing accurate. Mastra manages the timing and retries if the network blips. This keeps your revenue tracking precise. By automating the data flow, you avoid the manual reconciliation work that usually eats up your time.
