"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.

Discover why RagAlgo is the "Hippocampus" for Agentic AI, not just another RAG.
Our production system on Railway processes global financial data 24/7:

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.
RagAlgo acts like a Professional Technical Analyst who works after the market closes:
Use RagAlgo to build "Investment Advisors", not "High-Frequency Trading Bots".
