What is the Ragalgo MCP server?

Dynamic RAG Engine preventing AI hallucinations in Korean Finance and Crypto markets. The ragalgo mcp server wraps that behind the Model Context Protocol, so an assistant can use it through 7 defined tools rather than through you.

What it actually does

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.

Its toolset

Everything the assistant can do here goes through one of these:

  • get_news_scored[RECOMMENDED] News WITH AI Sentiment Scores (-10 ~ +10). Filters out noise
  • get_news[Advanced] Raw News WITHOUT scores. Includes 0-score noise. Use only if you build your own scorer
  • get_chart_stock[Core] Global Stock (US/UK/JP/KR) Technical Analysis (Daily Close)
  • get_chart_coin[Core] Global Crypto Technical Analysis (Daily Close)
  • get_snapshots[Best] Market Overview (News + Chart + Trend) in one call
  • get_financials — Corporate Financials (Quarterly/Yearly)
  • search_tags — Convert names (e.g., "Samsung") to RagAlgo Tags

Configuration

You will need one environment variable: RAGALGO_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

When to reach for it

Among the AI and media services options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Ragalgo's toolset — get_news_scored, get_news, get_chart_stock and 4 more — is a fair guide to whether it matches your workflow. It is maintained by kokogo100; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Ragalgo's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the ragalgo mcp server does with a few real requests.

Frequently asked questions

It connects Ragalgo to MCP-compatible AI assistants such as Claude and Cursor, exposing 7 tools (get_news_scored, get_news, get_chart_stock, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Ragalgo directly.
