Lemon Squeezy for AI agents

Lemon Squeezy is a merchant-of-record platform that handles payments, taxes, and subscriptions for software companies selling online without building their own billing stack. Connect it once through Arc0, and your agent, or Claude, ChatGPT and Cursor, can use it through one MCP endpoint, limited to what each user approved.

07 · FAQ

Lemon Squeezy and Arc0, answered.

Q01

Can I use Lemon Squeezy with Claude, ChatGPT or Cursor?

Yes. Connect Lemon Squeezy to Arc0 once, then add your Arc0 MCP URL to Claude, ChatGPT, Cursor, Claude Code or any other remote-MCP client. Each assistant only gets the Lemon Squeezy actions you allow.

Q02

How do users connect Lemon Squeezy?

Users add their Lemon Squeezy api key on Arc0 Connect. It is encrypted in the vault, never shown to the model, and each user can rotate or revoke it at any time.

Q03

Which Lemon Squeezy actions can my agent take?

32 in total: 25 read, 5 write and 2 destructive, such as “create Webhook”. Your policies decide which of them each agent may call.

Q04

Can I stop my agent from deleting things in Lemon Squeezy?

Yes. Actions like “delete Webhook” are graded destructive. Set destructive actions to deny, or to ask so the user approves each one, and blocked calls still show up on the audit log.

Q05

Can my own backend call Lemon Squeezy too?

Yes. The same Lemon Squeezy connection is available over REST and through the Arc0 proxy, so your product and your agent share one connection per user.
