Connect an assistant
Add Arvald to Claude or ChatGPT, sign in once, and start asking.
Connecting takes one address and one sign-in. You do not create an API key, paste a secret, or configure any permissions.
https://mcp.arvald.comClaude
- Open Settings, then Connectors.
- Choose Add custom connector.
- Paste the address above and add it.
- Claude opens an Arvald sign-in page. Sign in the way you normally do.
- Approve the connection.
Ask it something read-only first, like "which brands can you see?", to confirm it is working.
ChatGPT
ChatGPT needs developer mode, which is on Plus, Pro, Business, Enterprise and Edu plans. On a Business or Enterprise workspace an admin may have to allow custom connectors first.
- Open Settings, then Apps, then Advanced settings, and turn on developer mode.
- Add a custom connector with the address above.
- Sign in to Arvald when prompted and approve the connection.
- Pick the connector in the composer for the conversations you want it in.
Signing in
The sign-in is the normal Arvald one and happens in your browser, not in the assistant. The assistant never sees your password.
What it gets is a limited access token, which is what carries your identity to Arvald on every request. That token is why the assistant sees your brands and only yours.
If it does not connect
"Authentication required", or "no MCP server was found at the provided URL". Check the address
is exactly https://mcp.arvald.com, with nothing after it. Both that address and the same address with
/mcp on the end work, so a trailing path is not the problem, but a typo in the host is.
It signed in, then failed on the first request. Disconnect and reconnect. A newly connected assistant is registered on our side moments after it first appears, and a connection made in that gap has to be redone once. It does not recur for that assistant.
It cannot see a brand you own. The assistant sees what your account sees. Confirm you are a member of that brand in the dashboard, under Settings.
Other assistants
Anything that speaks the Model Context Protocol and can sign in with OAuth should work. Claude and ChatGPT are the two we test against, so those are the two we can promise.
