k-data-mcp

MCP server for Korean equity research and market data, metered per call in USDC over x402. Start it without a wallet to inspect the catalog and run free, date-stamped previews; add a dedicated wallet only when you want paid calls.

Try before funding a wallet

Run npx k-data-mcp with no environment variables to use these free tools:

list_endpoints — paid catalog and prices.
preview_research_coverage — real per-ticker report/brokerage counts and archive date ranges.
preview_research — a single ticker's actual archive depth; this does not disclose report content.
preview_kimchi_premium — live BTC-only dual-basis sample.

Set K_DATA_PRIVATE_KEY and K_DATA_MAX_SPEND_USD only when you are ready to enable paid tools.

What you get

Kimchi premium on a tradeable basis. Everyone quotes the premium against the official USD/KRW rate, but Korean capital controls mean the KRW exit leg actually goes through USDT — so that number is not something you can trade on. This returns both, and they routinely disagree *in sign*: official can read −0.27% while the realizable basis is +0.19%.
Premium history and percentile context. A continuously recorded archive answers "is this premium unusual right now?" — percentile, mean, stdev, z-score over 1h–90d. No free source publishes this, and it cannot be reconstructed after the fact.
Korean headlines translated to English, from Yonhap, Maeil Business and Hankyung. Korean myriad units (억 / 조) are expanded deterministically before translation, so "989억달러" comes back as *$98.9 billion* rather than the 10×-off answer language models produce unaided.
Korean sell-side research as structured data. Target prices, ratings, brokerage and analyst per KRX ticker, each with an English summary, plus the consensus and revision history built from them — who raised, who cut, and how far apart the houses actually are. Only the facts of each report are sold, in our own words, with a link back to the publisher; the report PDF stays with the brokerage that wrote it. The listing source shows a rolling recent window only, so this series cannot be reconstructed after the fact either.
Upbit KRW quotes and market summaries, USD/KRW.

Install

npx k-data-mcp

Claude Desktop / Claude Code

"mcpServers": { "k-data": { "command": "npx", "args": ["-y", "k-data-mcp"], "env": { "K_DATA_PRIVATE_KEY": "0xYOUR_DEDICATED_WALLET_KEY", "K_DATA_MAX_SPEND_USD": "1" } } } }

Wallet setup

Each tool call spends real USDC, so the server will not start without a key and a budget.

Create a dedicated wallet — not your main one. The key sits in a config file and every call spends from it.
Fund it with the USDC you're willing to spend on Base. No ETH needed: x402 settles with an off-chain EIP-3009 signature and the facilitator pays the gas.
Set K_DATA_MAX_SPEND_USD. The server refuses any call that would push cumulative spend past it.

Variable	Required	Default	Meaning
`K_DATA_PRIVATE_KEY`	yes	—	Private key of the paying wallet (USDC on Base)
`K_DATA_MAX_SPEND_USD`	no	`1`	Hard cap on cumulative spend for the session
`K_DATA_BASE_URL`	no	hosted service	Point at a different K-Data deployment

Tools

list_endpoints is free — call it first to see current prices and decide what's worth buying.

Tool	Price	Returns
`list_endpoints`	free	Catalog, current prices, wallet address, remaining budget
`kimchi_premium`	$0.03	Dual-basis premium (official + USDT) for up to 10 coins
`kimchi_premium_stats`	$0.12	Percentile, mean, stdev, z-score of the premium over 1h–90d
`kimchi_premium_history`	$0.08	Premium time series, both bases
`korea_market_snapshot`	$0.08	One-call briefing: premium + markets + FX + translated headlines
`research_consensus_ticker`	$0.12	Analyst consensus for one KRX ticker — target price mean/median/range and spread, rating mix, and every house's revision history
`research_company_ticker`	$0.05	Archived Korean brokerage reports for one ticker, summarised in English
`research_latest`	$0.02	Latest Korean equity research across all covered companies
`news_headlines_en`	$0.05	Korean headlines with English translations
`crypto_krw_markets`	$0.01	All Upbit KRW markets — volume leaders, gainers, losers
`news_headlines`	$0.01	Korean headlines, untranslated
`crypto_krw_ticker`	$0.005	One Upbit KRW quote
`fx_usdkrw`	$0.005	USD/KRW rate

Prices are read from the provider's catalog at startup, so this table reflects whatever the service currently charges.

How payment works

Every paid endpoint answers an unpaid request with HTTP 402 and a PAYMENT-REQUIRED header describing the price, asset and recipient. This server signs an EIP-3009 authorization for that exact amount and retries; the facilitator settles it on Base. Nothing is held on account — you pay per call, and stop paying when you stop calling.
