Connect Claude to Clarus

Add Clarus to Claude as a custom connector, then ask Claude about your warehouse — and have it make changes — in plain English. Setup takes a minute and uses your normal Clarus sign-in.

AI accuracy: AI-generated responses can sometimes be inaccurate, incomplete, or misleading. Always verify the assistant’s output before acting on it — especially for stock movements, order changes, or any actions that affect your live warehouse data. The assistant is a tool to help you, not a replacement for your own judgement.

Before you start, have your connection address ready:

https://agents.claruswms.ai/mcp/{subdomain}

Replace {subdomain} with your Clarus subdomain. See Connect AI assistants to Clarus if you’re unsure what yours is.

Custom connectors are a Claude feature (currently in beta) available on plans that support them — Pro, Max, Team, and Enterprise. Menu names can vary between Claude versions.

Add the connector

For your own account (Pro / Max)
For your whole organisation (Team / Enterprise)

Open Connectors

In Claude, go to Customize → Connectors. (You can also open the + menu in a chat, choose Connectors, then Manage connectors.)

Add a custom connector

Click the + next to Connectors, then choose Add custom connector.

The Connectors + menu showing Browse connectors and Add custom connector

Enter the Clarus details

In the dialog, give it a name like Clarus and paste your connection address (https://agents.claruswms.ai/mcp/{subdomain}). Under Advanced settings, leave OAuth Client ID and OAuth Client Secret blank — Clarus handles sign-in for you. Then click Add.

The Add custom connector dialog with a name and the Clarus URL, and the OAuth fields left blank

Claude opens a Clarus sign-in window — sign in with your Clarus username and password and approve access.

Use it in a chat

Start a new chat, make sure the Clarus connector is enabled (via the + menu), and ask a question such as “How many units of WIDGET-RED-500 are in stock?”

An organisation owner adds Clarus once for the team. It’s then available to everyone, but each person still signs in with their own Clarus account — so they only see and do what their account allows.

Owner: open organisation connectors

An organisation Owner goes to Organization settings → Connectors.

Claude Connectors page with the + Add button

Owner: add a custom Web connector

Click + Add, choose Custom, then choose Web (Clarus is a hosted server, so it’s a Web connector — not Desktop).

The Add menu showing Custom, then Web and Desktop options

Owner: enter the Clarus details

In the Add custom connector dialog:

Name: Clarus
URL: your connection address (https://agents.claruswms.ai/mcp/{subdomain})
Under Advanced settings, leave OAuth Client ID and OAuth Client Secret blank.
Under How your team connects, choose Individual sign-in (each person signs in to Clarus with their own account).

Then click Add.

The Add custom connector dialog with name, URL, blank OAuth fields, and Individual sign-in selected

Each member: sign in to Clarus

Every team member opens Customize → Connectors and selects Clarus, then clicks Connect and signs in with their own Clarus username and password.

Once connected, Clarus shows as available along with the tools Claude can use. You can set each tool to run automatically, ask for approval, or be blocked — Claude only ever sees the tools your organisation has given you access to.

Claude connects as you and uses your Clarus permissions, so it can change data as well as read it — for example updating an order or adjusting stock. Be specific about what you ask, and review any changes before confirming them.

Troubleshooting

Should I fill in OAuth Client ID / Secret?

No — leave both blank. Clarus uses a sign-in (OAuth) flow that’s set up automatically, so you don’t create or paste any client ID or secret.

I can't find Connectors

On a personal account, connectors live under Customize → Connectors. On a Team or Enterprise account, an owner adds connectors under Organization settings → Connectors, and members then manage their own sign-in under Customize → Connectors.

The connector won't add or shows an error

Double-check the address is exactly https://agents.claruswms.ai/mcp/{subdomain} with your real subdomain in place of {subdomain} and no trailing spaces. If you’re an organisation owner, make sure you chose Web (not Desktop). Your subdomain is your organisation’s short name in Clarus (see the overview).

It keeps asking me to sign in

Claude says it can't find data or isn't allowed

The assistant can only see and do what your Clarus account can. If you’re missing data or an action fails, check your own Clarus permissions for that account, warehouse, or feature — or ask your administrator.

Can Claude change my data?

Yes — within your permissions it can make changes as well as read. Ask precisely and confirm anything important before it acts.
