MerchantPro for AI agents

MerchantPro is an e-commerce platform for managing storefronts, catalogs, orders, and customer data for online retailers running their own branded stores. 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.

04 · AUTH AND DATA

How MerchantPro connects.

Users add their MerchantPro 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.

The same MerchantPro connection serves your agent over MCP and your own backend over REST and the proxy, so a user connects once. How Arc0 handles credentials →

AUTH: API key
CREDENTIALS: Per-tenant encrypted vault
MODEL SEES: Results only, never credentials
AUDIT LOG: Every call, on every plan

07 · FAQ

MerchantPro and Arc0, answered.

Q01

Can I use MerchantPro with Claude, ChatGPT or Cursor?

Yes. Connect MerchantPro 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 MerchantPro actions you allow.

Q02

How do users connect MerchantPro?

Users add their MerchantPro 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 MerchantPro actions can my agent take?

10 in total: 10 read, 0 write and 0 destructive. Your policies decide which of them each agent may call.

Q04

Can I make my agent read-only in MerchantPro?

Yes. Allow read actions and deny writes in the MerchantPro policy. Your agent can still look things up, and any write it attempts is blocked and logged.

Q05

Can my own backend call MerchantPro too?

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