This server connects Claude to daily-close financial data for Korean, US, UK, Japanese stocks and crypto, specifically designed to prevent hallucination by avoiding real-time tick noise. You get scored sentiment analysis on news, technical chart indicators, and combined snapshots through tools like get_news_scored, get_chart_stock, and get_snapshots. The scoring system returns values from negative ten to positive ten for sentiment and zero to one hundred for technical signals. Reach for this when you're building investment analysis agents that need verified post-market data rather than live trading feeds. It ships with both cloud and local stdio modes, and the free tier gives you a thousand API calls to test with.
"Your AI is an Analyst, NOT a Day Trader."
RagAlgo is an MCP Server that provides mathematically scored financial context (Korean Stocks/Crypto) to AI agents. We focus on "State-of-Truth" (Daily Closed Data) to prevent AI hallucinations caused by real-time market noise.

Users often ask: "Why isn't the chart data real-time?"
Because AI performs better with clarity. Real-time tick data is full of noise and volatility. If you feed an LLM raw live prices, it often hallucinates patterns that don't exist.
