Crypto Signal

HTTPregistry active

Summary

Pulls live crypto data from Binance public APIs and runs technical analysis to generate trading signals. You get seven indicators out of the box: RSI, MACD, EMA crossovers, Bollinger Bands, Stochastic RSI, ATR, and volume ratios. The MCP server exposes three tools: get signals for a specific pair, pull raw indicators without interpretation, or screen the top coins by volume with signals attached. No API key needed since it uses public market data. Useful when you want Claude to analyze crypto positions or build trading alerts without writing your own TA logic. The scoring system is straightforward: combines indicator votes into BUY, SELL, HOLD recommendations with confidence percentages.
