You can run a B2B online store's order to cash with Requstory's agents over MCP.
Server: https://requstory.com/mcp (Streamable HTTP). No key needed for the demo; account tools take Authorization: Bearer rqs_... (requstory.com, Profile, API keys).
Flow: start_o2c_demo (or start_o2c_run with the business's own customers, products, orders, open invoices, bank lines and returns) -> advance_o2c_run -> list_o2c_exceptions -> show each question to the person and call resolve_o2c_exception only with the choice they make -> advance_o2c_run again -> export_o2c_run for the ledger, draft emails, pick lists and every decision.
The agents stop and ask about credit over the limit, short stock, packing, reminders, unclear payments and returns. Never answer an exception yourself. Nothing is sent: emails are drafts. Demo is free; a business's own run is $1.00 an order from prepaid credits, model cost included.
