Acts, when you ask

These change something in Swell. 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.

• swell_add_noteAdds an internal note to an order, subscription or invoice in Swell.
• swell_update_orderChanges an order's state flags in Swell: put it on hold or release it, close it, or mark it delivered, and/or replace its internal admin notes field.
• swell_cancel_orderCancels a Swell order with a reason.
• swell_delete_orderPermanently deletes a Swell order; Swell's docs say the deletion is permanent.

Connect it

First connect Swell on Dashboard → Connections, then add Memtro to your client once. The Swell 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 Swell 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.

Ask it like this

• › Which orders are still awaiting payment?
• › Who are our top customers by lifetime value?
• › Which products are low on stock?
• › Which subscriptions reach the end of their period this week?
• › Add a note to order 1042 saying the customer called about delivery.

Questions

Is this an official Swell MCP server?

No. It is Memtro's MCP server with Memtro's Swell connector behind it: the connector reads Swell through its API with the credentials you connect on Dashboard → Connections, and Swell 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 Swell?

Only when you ask, and only what it has been granted: add an internal note to an order, subscription or invoice; hold, close or mark an order delivered; cancel an order; delete an order; create a shipment for an order; update a shipment's tracking; refund a payment; create a return for an order; cancel a subscription, now or at a scheduled date; reinstate a canceled subscription; pause a subscription; resume a paused subscription; adjust a product's stock; update a product's name, price, SKU or visibility. 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.
