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
Claude Code installed on your Windows or Mac machine
Your Cryptohopper MCP API key (bearer token)
Setup
Open a terminal on your computer.
Run claude and confirm Yes, trust this folder when prompted.
Paste the following configuration, replacing YOUR_REAL_MCP_API_KEY with your actual bearer token:
{
"mcpServers": {
"Cryptohopper.com Market Data": {
"type": "http",
"headers": {
"Authorization": "Bearer YOUR_REAL_MCP_API_KEY"
}
}
}
}
Tell Claude Code: "Add to Claude Code settings — install the Cryptohopper Exchange Data MCP server so I can use it in sessions."
When asked to update the config, choose Yes, and don’t ask again.
Select project-level and confirm claude mcp add. Pick Yes, I’m comfortable with that only on your own device (for security reasons).
You’re ready — start asking your questions.
Doesn’t it work?
Authentication errors: Double-check that your bearer token is correct and has not expired. Regenerate it in your Cryptohopper account if needed.
Server not found: Make sure the URL is exactly https://mcp-data.cryptohopper.com/mcp and 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.
Missing dependencies: If a prompt requires additional tools or libraries, install them first, then retry your request
