Connect it

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

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

Only when you ask, and only what it has been granted: create a checkout link for a variant, optionally prefilled or at a custom price; refund an order in full or in part (moves money back to the customer); refund a subscription invoice in full or in part (moves money back to the customer); cancel a subscription at the end of its period; change a subscription's plan, pause or unpause it, resume a cancelled one, or move its trial end or billing day; change the quantity on a quantity-billed subscription item; report usage on a usage-billed subscription item; create a discount code; delete a discount code permanently; create a customer; update a customer's name, email or location, or archive them; change a license key's activation limit or expiry, or disable it; generate a downloadable invoice for an order. 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.
