Connect Varly to Claude
Add Varly as a connector in Claude, so you can ask about your research and build tests from the chat.
In this article
Varly works as a connector in Claude (the technical name is an MCP server). Once it's connected, you can ask Claude about heatmaps, click impact and surveys, have it write test ideas and build A/B test variants, and launch them from the chat. Claude works with your own Varly login, so it sees exactly the clients and sites you can see, and nothing more.
Step 1: Copy the Varly address
- In Varly, click your name or photo at the top right to open Account.
- Find the card Connect Claude or ChatGPT.
- Click the copy button next to the address. It ends with
/mcp.
Step 2: Add the connector in Claude
- In Claude, go to Settings, then Connectors, then Add custom connector.
- Paste the Varly address.
- Click Connect.
Step 3: Log in and allow
- Claude opens a Varly window. Log in to Varly if you're asked to.
- Varly shows which app wants to connect, what it will be able to do, and for which clients or shops.
- Check the list and click the Allow button, which shows the app's name. Click Cancel if you don't want to connect.
You're back in Claude, and Varly is connected. Try asking: "Which clients do I have in Varly?"
What Claude may do
On the consent screen, Varly lists what the app asks for. Depending on that, Claude can:
| Permission | What it means |
|---|---|
| Read | Read research, ideas and experiment results for the clients you can access. |
| Create drafts | Create drafts: ideas, surveys and A/B test variants. Nothing goes live. |
| Launch | Launch and stop A/B tests on your live site, after showing you the preview link and the test plan in the chat. |
It also confirms who you are (your name and email address) and stays connected until you disconnect it.
Your role in Varly still applies. If you're a Viewer for a client, Claude can only read that client's data, whatever you allowed. Creating drafts and launching need the Editor or Owner role. See Team roles.
Check or remove the connection
On your Account page, under Connected apps, you see each connected app, what it may do (for example Can read, create drafts and launch tests) and since when.
To remove it, click Disconnect. This works right away: Claude can no longer reach Varly, and has to be connected and allowed again to use it. You can also remove the connector in Claude itself.
Common problems
Claude asks which client you mean. That's on purpose. Varly never guesses a client. If you have more than one, tell Claude the exact client name. See What you can ask the assistant.
Claude says the connection is read-only. The connection wasn't allowed to create drafts or launch tests. Disconnect it under Account → Connected apps and connect again.
Claude says "You have read-only access to this client in Varly." Your role for that client is Viewer. Ask an owner to change it.
Claude can't reach Varly at all. Check that the address ends with /mcp and was copied in full. If you disconnected before, connect again.
