4OVER4 connector

Find, configure and price custom printing from 4OVER4.COM in your AI assistant, then order on www.4over4.com. 4OVER4 has printed online since 1999, in its own plant in Queens, NY.

This repository holds no app code. It holds the files that list the 4OVER4 MCP server in assistants and directories: a Claude plugin, a Claude Code marketplace, a Gemini CLI extension and an MCP Registry entry.

MCP server: https://www.4over4.com/appsapi/mcp (Streamable HTTP, MCP 2025-11-25) Sign-in: OAuth 2.1 with dynamic client registration, at https://www.4over4.com/appsapi/oauth Help page for AI agents: https://www.4over4.com/ai-agents Developer API description: https://www.4over4.com/openapi.json

What you can do

Find custom printing: business cards, flyers, postcards, banners, signs, labels, stickers, invitations and more, by product, industry, occasion or budget.
Price it live: the total and price per piece for your quantity, size, paper, finish and turnaround, plus the quantity price breaks.
Delivery dates: an estimated in-hands date, or live carrier options for your ZIP code.
Help: answers from the 4OVER4 help center on files, bleed, papers, proofs, returns and more.
Order: a priced setup gives a Checkout on 4OVER4 button or a link to www.4over4.com, where you upload artwork, choose shipping and pay. No payment happens in the assistant.
After you sign in: your orders, tracking, invoices, profile, saved addresses, coins and cart; the link to cancel an order yourself on your 4OVER4 orders page.

Add it to your assistant

Claude Code

/plugin install 4over4 --marketplace 40ver4/4over4-connector

On Claude Code before 2.1.275, use two lines:

/plugin marketplace add 40ver4/4over4-connector
/plugin install 4over4@fourover4

Claude (web, desktop, mobile)

Settings, Connectors, Add custom connector, then paste https://www.4over4.com/appsapi/mcp. Add it on web or desktop first; it then works on mobile too.

ChatGPT

Search for 4OVER4 in the ChatGPT plugin directory and press Connect. Until the listing is approved, add it in ChatGPT's developer mode as a custom app with the URL https://www.4over4.com/appsapi/mcp.

Gemini CLI

gemini extensions install https://github.com/40ver4/4over4-connector

Cursor

Open this link: cursor://anysphere.cursor-deeplink/mcp/install?name=4over4&config=eyJ1cmwiOiJodHRwczovL3d3dy40b3ZlcjQuY29tL2FwcHNhcGkvbWNwIn0=

Or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "4over4": { "url": "https://www.4over4.com/appsapi/mcp" }
  }
}

VS Code

Run "MCP: Add Server", choose HTTP, and paste https://www.4over4.com/appsapi/mcp.

Cline, Grok, Goose, Zed and any other MCP client

Add a remote MCP server with the URL https://www.4over4.com/appsapi/mcp and no API key. The client opens the 4OVER4 sign-in page when an account tool needs it.

The tools

Group	Tools
Find	`show_products`, `list_categories`, `recommend`, `marketing_kit`, `find_similar_products`, `find_matching_print_products`, `compare_products`, `search_content`
Price and delivery	`configure_product`, `price_breaks`, `delivery_by_zip`, `daily_deals`
Print files	`calculate_print_resolution`, `calculate_print_bleed`, `convert_paper_weight`, `get_print_file_setup`
Help	`search_knowledge`, `talk_to_human`, `loyalty_tasks`
Your account (sign-in)	`get_my_orders`, `get_order_details`, `get_order_cancel_link`, `get_my_profile`, `get_my_coins`, `get_cart`

create_checkout runs only when you press Checkout on 4OVER4 on a price card: it opens www.4over4.com, where you pay, and charges nothing. get_order_cancel_link cancels nothing: it gives the link to your orders page on www.4over4.com, where you cancel a job yourself.

For AI agents and developers

Everything an agent needs is published on www.4over4.com. No API key is needed.

Sign-in: OAuth 2.1 with PKCE and dynamic client registration, scopes account and offline_access. Only the account tools need it. Without a token they answer 401 with a WWW-Authenticate header that points to the protected resource document, so any MCP client starts the sign-in by itself.
Prices and stock are live: every price, option and delivery date comes from the 4OVER4 shop at the moment of the call, never from a cached list.
Rate limits: 120 tool calls a minute for each signed-in customer or connection, and 1,200 a minute for each network address. Every answer carries the RateLimit-Policy and RateLimit headers, and Retry-After when a limit is reached.
Errors: HTTP errors are application/problem+json (RFC 9457), OAuth errors follow RFC 6749, and MCP errors follow JSON-RPC.
Safe by design: no tool takes payment or cancels an order. Checkout and cancellation finish on www.4over4.com, where the customer confirms.

Nothing here runs on your machine: no scripts, hooks or packages. Every tool runs on the 4OVER4 server.

Privacy

Without sign-in, the tools read only public product, price, delivery and help information. Your requests to the tools (for example a product name, a quantity or a ZIP code) reach our server.
After you sign in, the tools can read your own 4OVER4 orders, tracking, invoices, profile, saved addresses, QR codes, coins and cart, when you ask for them. They never cancel an order: get_order_cancel_link gives the link to your orders page on www.4over4.com, where you cancel it yourself.
What we receive: the tool request your assistant sends and, after sign-in, a connection token. We do not receive the rest of your conversation, and the assistant never sees your 4OVER4 password.
How long sign-in lasts: up to 30 days; each access grant lasts 1 hour and renews by itself. Disconnect 4OVER4 in your assistant's settings at any time.
Never collected here: card numbers or other payment details. Artwork upload, shipping and payment happen only on www.4over4.com.
Your assistant's provider receives the tool results under its own privacy policy.
