gocushy MCP server

Give any AI agent the tools to run a complete selling system: products, offers with order bumps and one-click upsells, hosted checkouts, subscriptions, coupons, embeds, orders, refunds, affiliates, email follow-up, and sales stats — on the merchant's own Stripe or PayPal account.

28 tools in all. Nothing is a mockup: the agent creates real checkouts that take real money into the merchant's own account. Totals, fees, and tax are computed server-side, so an agent can't ship a broken or mispriced checkout.

Install

npm install -g @gocushy/mcp

Point your client at the gocushy-mcp command (stdio transport), passing the merchant's API key:

{
  "mcpServers": {
    "gocushy": {
      "command": "gocushy-mcp",
      "env": {
        "GOCUSHY_API_KEY": "gc_your_key_here",
        "GOCUSHY_API_URL": "https://api.gocushy.com"
      }
    }
  }
}

Or run it without installing — swap the command for "command": "npx", "args": ["-y", "@gocushy/mcp"].

Then just talk: "Set up a checkout for my $49 course, add my $17 workbook as an order bump, and give me the embed code."

Create an API key at https://api.gocushy.com/signup.

Remote connection (ChatGPT and other hosted clients)

Prefer a URL over a local process? gocushy runs a hosted MCP endpoint. Put the merchant's key in the path:

https://gocushy-mcp.fly.dev/mcp/gc_your_key_here

For ChatGPT connectors (which can't carry a key in the URL), connect to https://gocushy-mcp.fly.dev/mcp and paste the API key on the consent screen — the server speaks OAuth 2.0 (PKCE) for exactly this handoff.

Tools

A representative slice — 28 in total, spanning products, offers, checkout copy & layout, delivery, orders & sales, refunds, coupons, affiliates, email follow-up, webhooks, and business/tax settings:

| Tool | What it does | |---|---| | connect_payment | Start Stripe onboarding (returns a URL for the human — the one manual step) | | connect_paypal | Connect a PayPal account as a payment rail | | payment_status | Is the account ready to take payments? | | create_product | Create a sellable product (one-time or subscription) | | create_offer | Compose a checkout: product + optional bump + optional one-click upsell, plus a per-offer top logo (checkout_logo_url) | | update_checkout | Customize checkout copy, layout, the brand banner, the per-offer logo, and the one-click upsell page (headline, body, accept/decline labels) | | create_coupon | A promo code buyers type at checkout — works on one-time and subscription offers | | get_checkout_link | Hosted checkout URL — works immediately | | get_embed_code | Copy-paste overlay snippet for any site | | list_orders / get_sales | Orders with bump/upsell flags; revenue and per-offer breakdown | | refund_order | Full or partial refund (reverses the transfer + fee) | | connect_email / set_followup | Wire buyers into the merchant's Mailchimp / ActiveCampaign sequences | | create_affiliate / create_webhook | Affiliate links with holdback; order webhooks for custom fulfillment |

The full tool list, with every parameter, is advertised by the server itself — your agent discovers it on connect.

Design principles

• Server-side truth. Totals, fees, tax, and state live in the API; tools can't create a broken or mispriced checkout.
• Fail loudly. Validation errors come back verbatim so the agent can fix its call and retry.
• One human touchpoint. Everything is agent-operable except payment-provider KYC, which is legally the merchant's to complete.
