Crypto Feargreed MCP Server

A mcp server that provides real-time and historical Crypto Fear & Greed Index data, powered by the Alternative.me. Exposed over MCP by the crypto feargreed mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

• Current Index — Retrieve the latest Fear & Greed Index value and classification
• Historical Data — Fetch historical index values for a specified number of days
• Trend Analysis — Analyze trends over time with statistics like average value and trend direction
• Tool-Only Support — Includes tool versions of all resources for compatibility with tool-only MCP clients
• Prompt Generation — Provides a prompt template for interpreting index values

Its toolset

Everything the assistant can do here goes through one of these:

• Resources — The Resources tool exposed by this server
• Tools — Index trend Analysis. Output: Fear & Greed Index Analysis (30 days): Latest Value: 45 (Fear) at 2025-03-15 00:00:00 UTC Average Value: 47.3 Trend
• Prompts — Output: Please interpret this Crypto Fear & Greed Index value and explain what it means for cryptocurrency markets (specifically Bitcoin): 45

Adding it to your client

The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

When to reach for it

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Crypto Feargreed MCP's toolset — Resources, Tools, Prompts — is a fair guide to whether it matches your workflow. It is maintained by kukapay; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the crypto feargreed mcp mcp server does with a few real requests.
