Install Prompt

Paste this into Claude Code to set it up:

I want to add the CoinMarketCap MCP Server to my Claude Code setup.

IMPORTANT: Never use Read/Edit tools on ~/.claude.json. Use jq via Bash instead.

Prerequisites: You need a CoinMarketCap API key. Sign up at pro.coinmarketcap.com and grab your key from the developer portal. The free tier includes 10,000 API calls per month.

Run this command to add the MCP server (replace your-api-key with your actual key):
```bash
jq '.mcpServers["coinmarketcap"] = {"type": "stdio", "command": "npx", "args": ["-y", "coinmarketcap-mcp-server"], "env": {"CMC_API_KEY": "your-api-key"}}' ~/.claude.json > /tmp/claude-json-tmp && mv /tmp/claude-json-tmp ~/.claude.json
```

After adding, restart Claude Code. The server connects to the CoinMarketCap API and gives the agent access to real time crypto data, technical analysis, and market insights.
