Quick answer
In Claude, open Customize > Connectors, select + Add, then Add custom connector, name it Nation and enter https://mcp.withnation.ai/mcp as the server URL. Claude then opens Nation's sign-in, where you choose the store Claude may work with and select Connect. Custom connectors work on Free, Pro, Max, Team and Enterprise plans, and on the Free plan you can add one custom connector.
Nation publishes this guide about its own connector. The steps for Claude come from its maker's own documentation, checked 13 Oct 2026. See where Nation fits.
What you need before you connect
- A Claude account on any plan. Custom connectors work on Free, Pro, Max, Team and Enterprise plans.
- On the Free plan, no other custom connector: the plan allows one custom connector.
- On a Team or Enterprise plan, an admin who can add connectors: on Team, an Owner or Primary Owner; on Enterprise, also people with a custom role that includes Manage access to Libraries.
- A Nation account and a store with an active plan.
- The Nation server URL: https://mcp.withnation.ai/mcp
Add Nation to Claude on a Free, Pro or Max plan
The Add custom connector dialog looks different in some accounts: some show the name, the URL and Advanced settings on one screen. Nation needs only the name and the URL.
Open Connectors
In Claude on the web or in Claude Desktop, open Customize > Connectors.
Add a custom connector
Select + Add, then Add custom connector.
Enter the name and URL
Enter Nation as the name and https://mcp.withnation.ai/mcp as the MCP server URL, then select Continue.
Keep OAuth sign-in
Nation signs in with OAuth. Under Authentication, choose Sign in now. If Claude asks for an OAuth client, choose Register automatically, which uses the dynamic client registration Nation supports. Leave Request headers empty, then select Add.
Sign in to Nation
Claude opens Nation's sign-in page. If it does not, select Connect next to Nation in Customize > Connectors. Finish the Nation steps in the next section.
Turn Nation on in a chat
In a chat, select the + button, then Connectors, and switch Nation on for that conversation.
Add Nation for a Claude Team or Enterprise organization
An Owner adds Nation once for the organization: go to Organization settings > Connectors, select Add, then Custom, choose Web if Claude asks for the type, enter https://mcp.withnation.ai/mcp and select Add.
Each member then opens Customize > Connectors, finds Nation with the Custom label and selects Connect. Every member signs in to Nation with their own email and picks their own store.
Nation is not in Claude's Connectors Directory yet. Once it is listed, you will be able to add it from the directory instead of by URL.
Sign in to Nation and choose your store
The Nation side is the same for every assistant.
Sign in with your email
Claude opens app.withnation.ai/mcp-auth. Enter the email you use for Nation and the one-time code Nation sends you. There is no password and no API key to copy.
Choose the account
If your email belongs to more than one Nation account, choose the one that owns the store.
Choose the store
Pick the store Claude may work with. One connection reaches one store. A store without an active plan is shown but cannot be picked.
Select Connect
Nation creates a key for that store named after the assistant and ending in (MCP), then sends you back to Claude.
What Claude can do in your store
Once Nation is connected, Claude works in the one store you picked, through Nation's tools.
Read tools only read. Tools that delete, refund, cancel or reach outside Nation are marked as destructive or open-world, so the assistant can ask you before it runs them. Changes it makes are saved in your store like any other change.
What to ask Claude once Nation is connected
Ask in plain words, the same way you would ask a person who runs the store with you:
- Which products sold best this month?
- Show me orders that still need to be fulfilled.
- What is running low on stock?
- Create a 15% discount code for returning customers.
- Make the homepage headline shorter, then publish the storefront.
Disconnect Nation from Claude
Sign in to Nation
Sign in at app.withnation.ai with your email and the one-time code.
Open Settings, then Developer
This page lists the keys that assistants use to reach your store.
Revoke the key
Revoke the key for Claude, the one ending in (MCP). Access stops at once. If you use Nation in Claude again, it asks you to connect again.
Remove the connector in Claude
In Customize > Connectors, select Remove or the three dots next to Nation and follow the prompts. Team and Enterprise Owners do this in Organization settings > Connectors.
If Nation does not work in Claude
- The store you want cannot be picked: it needs an active plan, or it belongs to another Nation account. Sign in with the email that owns it.
- Claude cannot reach the server: check that the URL is exactly https://mcp.withnation.ai/mcp, with /mcp at the end.
- Claude works in the wrong store: one connection reaches one store. Revoke the key in Nation and connect again, choosing the other store.
- Changes do not show on your live site: storefront changes stay unpublished until you publish them. Ask the assistant to publish the storefront.
- Nation does not appear in a chat: select the + button, then Connectors, and check that Nation is switched on for that conversation.
- You are on the Free plan and cannot add Nation: the Free plan allows one custom connector, so remove the one you have or upgrade.
- Still stuck: email dk@withnation.ai with the email you sign in with, the store name, the assistant you used, what you asked and roughly when.

Describe what you makeQuestions about connecting Nation to Claude
Do I need an API key to connect Nation to Claude?
No. Nation's connector signs you in with OAuth, so you never copy a key. Claude opens Nation's sign-in page, you enter your email and a one-time code, choose a store and select Connect. Nation then creates a dedicated key for that store itself, and you can revoke it in Settings, then Developer.
Can Claude change my store without asking?
Claude changes your store only when it calls one of Nation's write tools for you. Tools that delete, refund, cancel or reach outside Nation are marked as destructive or open-world, so the assistant can ask you first. Read those prompts before you approve them, and revoke the key in Nation if you want access to stop.
Can I connect more than one store to Claude?
One connection reaches one store, the one you pick while signing in. To work in a different store, revoke the key for Claude in Nation under Settings, then Developer, and connect again, choosing the other store. Stores without an active plan are shown in the list but cannot be picked.
Which Claude plans can connect to Nation?
Every plan can: Free, Pro, Max, Team and Enterprise support custom connectors in Claude on the web, Claude Desktop and Cowork. The Free plan allows one custom connector. On Team and Enterprise plans an Owner adds Nation for the organization, and each member then connects with their own Nation sign-in.
