Available tools 16

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

preview
preview_kimchi_premium
Free live BTC-only sample of the dual-basis kimchi premium. Use the paid endpoint for up to 10 symbols.
preview_premium_coverage
Free archive coverage and freshness for each recorded coin. Check sample count, first and latest timestamps, and stale flag before buying premium statistics or history.
preview_research
Free, date-stamped archive-depth check for one 6-digit KRX ticker. Shows report and brokerage counts, not report content or consensus.
preview_research_coverage
Free, date-stamped KRX research coverage. Lists the most-covered tickers with report count, brokerage count, and archive date range; it does not reveal report content.
kimchi
kimchi_premium
Kimchi premium on two bases: premium_official_pct (official USD/KRW rate — the quoted figure) and premium_usdt_pct (Upbit KRW/USDT rate — a gross spot-price comparison using KRW/USDT conversion, before spreads, fees, liquidity and transfer constraints). The two frequently disagree in sign. Optional ?symbols=BTC,ETH (max 10). Costs $0.03 in USDC per call, settled via x402.
kimchi_premium_history
Time series of the kimchi premium from the recorded archive, both bases, newest-last. Params: ?symbol=BTC &window=1h|6h|24h|7d|30d|90d &points=500 (max 2000) &before=<next_before>. Each page is a separate paid request. Continue while has_more is true using next_before. Inspect actual archive depth and freshness through /api/preview/premium-coverage before buying. Costs $0.08 in USDC per call, settled via x402.
kimchi_premium_stats
Where the current kimchi premium sits inside its own recent distribution: percentile, mean, stdev, z-score, min/max/median, and a plain-language read. Answers 'is this premium unusual right now?' in one call. Built from the recorded archive; inspect actual dates and freshness with the free coverage endpoint. Params: ?symbol=BTC &window=1h|6h|24h|7d|30d|90d &basis=usdt|official. Costs $0.12 in USDC per call, settled via x402.
research
research_company_ticker
Every archived Korean brokerage report for one KRX ticker, newest first: target price, rating, brokerage, analyst, the Korean title with its English translation, and a one-line English summary. Params: ?limit=20 (max 50). Costs $0.05 in USDC per call, settled via x402.
research_consensus_ticker
Analyst consensus for one KRX ticker, built from the archived research history: mean/median/min/max target price across brokerages, the spread between them, the rating distribution, and a revision log of every target-price and rating change each house has made. Consensus uses each house's latest view, so a weekly publisher does not outvote a quarterly one. Params: ?window=30d|90d|180d|365d (default 90d). Costs $0.12 in USDC per call, settled via x402.
research_latest
Latest Korean brokerage equity research across all covered companies, newest first — company and KRX ticker, target price, rating, brokerage, analyst, and a one-line English summary of each report. Facts and summaries only; the report PDF stays with its publisher and source_url links back to it. Optional ?limit=20 (max 50). Costs $0.02 in USDC per call, settled via x402.
crypto
crypto_krw_markets
Snapshot of all Upbit KRW crypto markets: top by 24h traded value, top gainers, top losers. Optional ?limit=30 (max 100) for the volume ranking. Costs $0.01 in USDC per call, settled via x402.
crypto_krw_ticker
Live quote for one Upbit KRW market by ticker symbol (e.g. BTC, ETH, XRP): price, 24h change, 24h high/low, 24h traded value in KRW. Costs $0.005 in USDC per call, settled via x402.
news
news_headlines
Latest Korean headlines from Yonhap, Maeil Business and Hankyung, deduplicated and newest-first. Titles stay in Korean — use /api/news/headlines/en for English. Optional ?category=top|economy|tech|politics and ?limit=30 (max 100). Costs $0.01 in USDC per call, settled via x402.
news_headlines_en
Latest Korean headlines with English translations attached (title_en), from Yonhap, Maeil Business and Hankyung — deduplicated, newest first. Use this instead of the Korean-only route when the consuming agent does not read Korean. Optional ?category=top|economy|tech|politics and ?limit=20 (max 50). Costs $0.05 in USDC per call, settled via x402.
korea
korea_market_snapshot
One-call Korea briefing: dual-basis kimchi premium + top Upbit KRW markets + USD/KRW + latest economy headlines translated to English. Everything needed for a Korea market read in a single paid request. Costs $0.08 in USDC per call, settled via x402.

K-Data — Korean Sell-Side Research & Market Data — questions

Answers built from our own checks of this server.

What can K-Data — Korean Sell-Side Research & Market Data do?
It exposes 16 tools, read directly from the server on our last check. Among them: crypto_krw_markets, crypto_krw_ticker, fx_usdkrw, kimchi_premium, kimchi_premium_history, kimchi_premium_stats and 10 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is K-Data — Korean Sell-Side Research & Market Data mostly used for?
Its tools cluster around preview, kimchi and research. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is K-Data — Korean Sell-Side Research & Market Data working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 182 ms. The bar chart above shows every period we have measured.
How do I connect K-Data — Korean Sell-Side Research & Market Data?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does K-Data — Korean Sell-Side Research & Market Data need an API key?
No. K-Data — Korean Sell-Side Research & Market Data completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 16 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is K-Data — Korean Sell-Side Research & Market Data?
It answers our handshake in 182 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use K-Data — Korean Sell-Side Research & Market Data?
The npm package k-data-mcp was installed 122 times in the last week. Week over week that is +37%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is K-Data — Korean Sell-Side Research & Market Data open source?
The code is open source: it is published under the MIT licence, written in TypeScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at k-data-x402-production.theblack1022.workers.dev, which runs on its operator's own terms.
