This article shows you how to connect the Cryptohopper Market Data MCP server to Claude so you can query market data directly from your chat — set up once in your browser, then use it in the desktop app.
Prerequisites
An active Claude subscription
A custom connector must be added through your browser — this is a one-time setup step. (Claude's Windows and Mac desktop apps don't support adding custom connectors directly, but once added, the connector works there too.)
(Recommended) The Claude desktop app for Mac or Windows — this is where you'll use the connector day to day once setup is complete
No API key is required. The connection is authorized securely through your browser during setup.
One-time setup (in your browser)
Open Claude in your browser and make sure you're logged in.
Go to Settings → Connectors.
Click Add custom connector (depending on your interface, you may first need to select Customize or the + button).
Fill in the two fields:
Name: Cryptohopper Market Data
Remote MCP server URL:
https://mcp-data.cryptohopper.com/mcp
Then click Add.
A new Cryptohopper page will open asking for permission to connect. Click Approve.
You're ready — and the desktop app is set up too
Tip: Enable "always allow" to ensure your Claude can always do the research you want it to do.
That's it for setup. The connector is now active, and it automatically appears in your Claude desktop app as well, with no extra steps. If you have the desktop app installed, just open it and you'll find Cryptohopper Market Data ready to use.
If you don't see it right away, restart the app and it should appear. From here on, you can simply work in the desktop app and start asking your questions.
