Crypto Fear & Greed Index MCP server
by kukapay
Lets your AI check the crypto Fear & Greed Index, past values, and trends whenever you ask.
This is a small helper that connects your AI assistant to the Crypto Fear & Greed Index, a well known number that shows how scared or greedy the crypto market feels right now. It is handy if you follow Bitcoin or crypto and want quick, plain answers instead of opening a website and reading charts yourself.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program that gives your AI one new skill or one new connection. This helper connects your AI to the Crypto Fear & Greed Index, so when you ask about the market mood, the AI can actually go and look up the real, current number for you.
What this MCP server does
You ask your AI something like what the crypto Fear & Greed Index is today. The AI passes your question to this helper. The helper then asks the public Alternative.me data service for the latest number and its label, such as Fear or Greed. The AI reads that answer and explains it back to you in the chat. You can also ask for past days or a trend, and the helper fetches that history the same way.

Good to know
This only reads public market sentiment data, so it cannot change or delete anything, but it is not financial advice and you should not treat the number as a prediction.
