Provides real-time and historical Crypto Fear & Greed Index data, enabling market sentiment analysis within MCP-compatible clients.
This MCP server is generally safe due to its read-only nature and lack of sensitive operations. However, reliance on an external API introduces a dependency risk. It is safe to use for informational purposes but should not be used in critical decision-making without verifying the data source.
Performance is primarily limited by the Alternative.me API response times. Caching of results may improve performance, but this is not implemented in the base server.
The primary cost consideration is the potential for exceeding the usage limits of the Alternative.me API, if any. Excessive requests could lead to rate limiting or service disruption.

This MCP server is generally safe due to its read-only nature and lack of sensitive operations. However, reliance on an external API introduces a dependency risk. It is safe to use for informational purposes but should not be used in critical decision-making without verifying the data source.
The server only provides read-only access to market data, so autonomy is limited to data retrieval and analysis. No destructive actions are possible.
Production Tip
Implement rate limiting on the client-side to avoid overwhelming the Alternative.me API and ensure stable operation.
It's a metric that gauges market sentiment by analyzing factors like volatility, social media, and dominance to assess whether investors are feeling fearful or greedy.
The data is provided by the Alternative.me Fear & Greed Index API.
The update frequency depends on the Alternative.me API. Refer to their documentation for specifics.
Yes, you can incorporate the index data into your trading strategies, but exercise caution and verify the data's accuracy.
The server itself is free, but excessive API calls to Alternative.me could potentially incur costs or rate limiting.
Values range from 0 (Extreme Fear) to 100 (Extreme Greed), indicating the prevailing market sentiment.
Use the Smithery CLI or manually configure the server in your Claude Desktop settings as described in the README.
