Manage customer billing records over MCP

Read and manage credits, invoices and payment records from an MCP client.

The API reference for creating an invoice, which the new create_invoice tool calls.

Agents can work with the same billing records shown in the dashboard.

  • Read credits, balances, invoices and payments, with customer filters and pagination.
  • Create or remove credits, prepare invoices, and update or delete invoice drafts. send_invoice emails the customer, so review the recipient and amount before calling it.
  • create_payment and refund_payment update payment records in Last Price; these tools do not transfer or refund money through a payment provider.

Reads require billing read access. Changes require billing write access and a claimed workspace.
