ragalgo — Claude Code MCP server: what it does, how to install
Feeds AI agents mathematically scored stock and crypto indicators calculated at market close. Stops hallucinations caused by raw tick noise.
claude mcp add ragalgo -- npx -y ragalgo-mcp-serverWhat ragalgo does
ragalgo delivers normalized metric scores from 0 to 100 alongside market zones instead of raw pricing streams. It targets equities across the US and South Korea, as well as crypto assets. Since the system calculates data after trading sessions conclude, assistants work with verified summaries rather than intraday price swings.
The underlying data pipeline ingests market news and computes ratings, publishing a consolidated snapshot daily at 18:00 KST. Running queries requires a valid RAGALGO_API_KEY. Attempting to use this server for sub-second day trading will fail, because its design deliberately excludes live order book feeds.
What it helps with
- evaluate stock scores after the trading session closes
- inspect daily sentiment ratings for crypto assets
- generate post-market summaries without live feed noise
- feed verified market zones to an investment analysis agent
Example prompts for the agent
- Fetch the daily score and market zone for KOSPI index assets.
- Generate an end-of-day crypto summary using yesterday's snapshot metrics.
- Check technical ratings for US equities before writing the investment brief.
