MCP server delivering real-time and historical Crypto Fear & Greed Index data.
https://github.com/kukapay/crypto-feargreed-mcpYou're building crypto analysis tools, trading bots, or market research workflows. You need the Fear & Greed Index data, but you don't want to spend time building yet another API integration for something this straightforward.
This MCP server delivers real-time and historical Crypto Fear & Greed Index data directly into Claude Desktop. No API keys, no rate limit management, no boilerplate HTTP client code.
Instead of writing API integration code every time you need Fear & Greed Index data, you get instant access through natural language queries. Ask Claude "What's the current crypto fear index?" and get structured data back immediately.
The server handles the Alternative.me API integration, caching, and data formatting so you can focus on analysis instead of plumbing.
Instant Market Sentiment Analysis: Get current Fear & Greed Index values (0-100 scale with classifications) without context switching to external tools or building API calls.
Historical Trend Analysis: Pull up to 365 days of historical data for backtesting strategies or identifying sentiment patterns. The server includes built-in trend analysis with averages and direction indicators.
Natural Language Interface: Skip writing HTTP requests. Ask Claude "Show me the fear index trend for the last 30 days" and get formatted analysis with trend direction and statistics.
Zero Configuration: No API keys needed since it uses Alternative.me's public endpoint. The server handles rate limiting and caching automatically.
Trading Bot Development: Integrate fear/greed signals into your algorithms without writing API integration code. Get current sentiment scores to inform position sizing or entry timing.
Market Research: Quickly pull historical sentiment data for correlation analysis with price movements. Ask Claude to analyze fear index patterns during specific market events.
Portfolio Management: Use sentiment data as a contrarian indicator. When fear is high (index below 25), it might signal buying opportunities.

Or clone and configure manually if you need custom setup.
The Fear & Greed Index is one of the most referenced sentiment indicators in crypto. Having it accessible through Claude means you can incorporate market psychology data into any analysis workflow without breaking stride to fetch external data.
Whether you're backtesting strategies, researching market cycles, or building trading tools, this server eliminates the friction between needing sentiment data and actually using it in your work.
