Connect Stripe. Stripe opens its own sign-in. Sign in and allow ApexGenius.

Then ask Codex:

Which Stripe account is connected, and is it live mode or a sandbox? Use the read-only route. Do not change anything.

Before you start

  • An account with permission to use the Stripe resources you intend to connect.

Step 1 of 4Open Plugins

The walkthrough uses the original ChatGPT web plugin captures. After connecting, open Codex in the desktop app and start a new task with ApexGenius. A ChatGPT web connection does not verify Codex access.

A public ApexGenius plugin listing is not verified. Use a plugin shared with you or one you created, subject to your account and workspace policy.

The desktop app, CLI, and IDE extension share MCP configuration on the same host. The IDE extension does not install plugins. ChatGPT web does not read local Codex configuration.

Limits in Stripe

  • · Stripe’s consent page sets the reach: live mode accounts, sandboxes or both, with permissions for each. An administrator can turn MCP access on or off for live mode and sandboxes separately.
  • · The connector acts only on the Stripe account you connect. It is separate from how ApexGenius bills you.
  • · Reads use a route that checks Stripe’s live read-only label. stripe_api_write moves money and runs right away when enabled.
  • · For some writes, such as refunds, Stripe returns its own confirmation link. Approve it on Stripe, then ask your AI to retry.
  • · Disconnecting ends ApexGenius access and asks Stripe to revoke the grant. It does not undo a refund, invoice or subscription change that already ran.

Try asking

“Which Stripe account is connected, and is it live mode or a sandbox?”

“List my last ten payments with amount, currency and customer. Do not change anything.”

“Which invoices are open or past due, and for which customers?”

“Refund this payment in full. Show me the amount, currency and customer first.”

One ApexGenius account covers every pair below. Connect an app once and each agent you allow can use it.

Questions people ask first

How do I connect Stripe?

Open Stripe in ApexGenius Connections and choose Connect. Sign in on Stripe’s page and pick the accounts or sandboxes to share. No Stripe API key is pasted into ApexGenius.

Can I connect only a sandbox?

Yes. On Stripe’s consent page, grant only a sandbox. Stripe lets you set different permissions for live mode and each sandbox, and an administrator can turn MCP access on or off for each.

Can my AI refund a payment or create an invoice?

Yes, through stripe_api_write. It runs right away when enabled. For some writes, such as refunds, Stripe also sends a confirmation link. A refund cannot be undone.

Which Stripe tools are included?

The ten tools Stripe documents for its MCP server: account and balance, API search and details, a read tool for any GET method, a write tool for POST, PATCH, PUT and DELETE methods, analytics, docs search, the implementation planner and feedback.

Can I undo a change?

Not always. A refund cannot be undone. An open invoice can be voided, and a payment link can be turned off. A canceled subscription cannot be restarted. Disconnecting stops future access only.

Does this touch how ApexGenius bills me?

No. The connector acts only on the Stripe account you connect. ApexGenius billing is separate and is never reached through it.
