This article shows you how to connect the Cryptohopper Market Data MCP server to Claude Code so you can query market data directly from your terminal.
Prerequisites
An active Claude subscription
Either your Cryptohopper MCP API key (bearer token) — found in your user profile under MCP API Keys — or use OAuth2 authentication (no key required).
Setup
Open a terminal on your computer:
Windows 10: Press Windows key + R, type
cmd, and press Enter. The Command Prompt will open.Windows 11: Click the Search bar in the taskbar (or press the Windows key), type
Terminal, and click Terminal in the results. Alternatively, right-click the Start button and select Terminal.Mac: Press Cmd + Spacebar to open Spotlight, type
Terminal, and press Enter.
Type claude and press enter. confirm Yes, trust this folder when prompted.
Choose one of the following authentication methods and paste the corresponding configuration:
Option A — API Key (bearer token)
Replace YOUR_REAL_MCP_API_KEY with your actual bearer token. You can find this token in your Cryptohopper profile under MCP API Keys.
{
"mcpServers": {
"Cryptohopper.com Market Data": {
"type": "http",
"url": "https://mcp-data.cryptohopper.com/mcp",
"headers": {
"Authorization": "Bearer YOUR_REAL_MCP_API_KEY"
}
}
}
}Option B — OAuth2 (no API key required)
{
"mcpServers": {
"Cryptohopper.com Market Data": {
"type": "http",
"url": "https://mcp-data.cryptohopper.com/mcp"
}
}
}
4. Tell Claude Code: "Add to Claude Code settings — install the Cryptohopper Exchange Data MCP server so I can use it in sessions."
5. When asked to update the config, choose Yes, and don’t ask again.
6. Select project-level and confirm claude mcp add. Pick Yes, I’m comfortable with that only on your own device (for security reasons).
7. You’re ready — start asking your questions.
Doesn’t it work?
Claude Code not installed yet: Ensure you've installed Claude Code. Check the article "How do I install Claude Code in the terminal" for more information.
Authentication errors: If you're using an API key, double-check that your bearer token is correct and has not expired. You can regenerate it in your Cryptohopper profile under MCP API Keys. If you're using OAuth2, make sure you completed the authentication flow when prompted.
Server not found: Make sure the URL is exactly
https://mcp-data.cryptohopper.com/mcpand that you selected Yes when prompted to update the config.MCP not listed in session: Restart Claude Code and confirm the server appears under your installed MCP servers.
If you're constantly being asked to re-authenticate: this can happen with OAuth login. An API key can help, but be aware it bills separately via the API rather than using your subscription.
Missing dependencies: If a prompt requires additional tools or libraries, install them first, then retry your request
