Squarespace Commerce MCP server

What the model can do

Squarespace store orders (customer, totals, payment and fulfilment state, line items), products with variants and prices, inventory levels, transaction documents with payments and refunds, and the site's contacts. On request it fulfils an order with tracking (emailing the customer only if asked), adjusts stock, adds, edits or deletes a contact, and deletes a product.

Acts, when you ask

These change something in Squarespace Commerce. 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.

• squarespace_create_contactAdd one contact to the Squarespace site's contacts, with first name, last name and email.
• squarespace_fulfill_orderMarks one Squarespace order fulfilled, adding the shipments given (carrier, service, ship date, tracking number and link).
• squarespace_adjust_inventoryChanges live stock for product variants on the Squarespace store: add to, take from, or set the quantity of each variant named.
• squarespace_update_contactEdits one contact on the Squarespace site: first name, last name, locale or email address.
• squarespace_delete_contactDeletes one contact from the Squarespace site's contacts, permanently.
• squarespace_delete_productDeletes one product from the Squarespace store, permanently: it disappears from the storefront.

Connect it

First connect Squarespace Commerce on Dashboard → Connections, then add Memtro to your client once. The Squarespace Commerce 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 Squarespace Commerce 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 Squarespace Commerce MCP server?

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

Only when you ask, and only what it has been granted: add a contact to the site's contacts (never subscribed to marketing); mark an order fulfilled with shipment tracking, emailing the customer only if asked; increase, decrease or set stock for product variants; edit a contact's name, locale or email (marketing consent untouched); delete a contact (permanent); delete a product from the store (permanent). 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.
