This article shows you how to connect the Cryptohopper Market Data MCP server to the Claude desktop app (Mac or Windows) so you can query market data directly from your chat.
Prerequisites
An active Claude subscription
The Claude desktop app installed on Mac or Windows
Your Cryptohopper MCP API key (bearer token)
Setup
Open the Claude desktop app.
Go to Settings → Developer → Edit Config. This opens the claude_desktop_config.json file in your default editor.
Paste the following configuration, replacing YOUR_REAL_MCP_API_KEY with your actual bearer token. If the file already contains an mcpServers block, just add the Cryptohopper.com Market Data entry inside it.
{
"mcpServers": {
"Cryptohopper.com Market Data": {
"type": "http",
"url": "https://mcp-data.cryptohopper.com/mcp",
"headers": {
"Authorization": "Bearer YOUR_REAL_MCP_API_KEY"
}
}
}
}
Save the file.
Fully quit and reopen the Claude desktop app (a simple window close is not enough).
Open a new chat and check that the Cryptohopper tools are listed under the MCP/tools icon.
You’re ready — start asking your questions.
Doesn't it work?
Authentication errors: Make sure your bearer token is correct and still valid. Regenerate it from your Cryptohopper account if needed.
Tools don’t show up: Fully quit the app (not just close the window) and reopen it. On Mac, use Cmd + Q; on Windows, quit from the system tray.
Invalid JSON: Double-check that the config file is valid JSON — a missing comma or bracket will prevent the app from loading MCP servers.
Server not reachable: Confirm the URL is exactly https://mcp-data.cryptohopper.com/mcp and that your network (firewall, VPN) allows the connection.
