What the model can do

Airwallex business account: current balances per currency, financial transactions (deposits, payouts, fees, conversions) with amounts and status, and Billing customers, invoices, subscriptions, products, prices and payment sources. Can create and update Billing customers, create, edit, finalize, void, delete, mark paid or charge Billing invoices, create and cancel subscriptions, and issue credit notes. Never transfers money out of the account.

Acts, when you ask

These change something in Airwallex. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

Connect it

First connect Airwallex on Dashboard → Connections, then add Memtro to your client once. The Airwallex tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Airwallex connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Questions

Is this an official Airwallex MCP server?

No. It is Memtro's MCP server with Memtro's Airwallex connector behind it: the connector reads Airwallex through its API with the credentials you connect on Dashboard → Connections, and Airwallex publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Airwallex?

Only when you ask, and only what it has been granted: create a Billing customer; update a Billing customer; create a draft Billing invoice; add line items to a draft invoice; edit a draft invoice; finalize an invoice (may email or charge the customer); mark an invoice paid out of band; void an invoice; delete a draft invoice (permanent); charge a finalized invoice to the customer's saved payment source; create a subscription; cancel a subscription, with the refund chosen; issue a credit note against an invoice. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
