# FinBridge

> NOTICE (2026-09-13): Enrolling reservation members ahead of service — US stock price and price-trend delivery is paused. Korean stock prices are served in get_stock_prices and on company pages (latest values for attested personal paid subscribers, otherwise delayed by at least 20 minutes); Korean valuation multiples and price screens stay paused. US prices are not part of what FinBridge sells today; delivery is planned, not promised. Sign up free to be told if that changes: https://finbridge.gronox.kr/login . Filings, financial statements, segments, insider trades and 13F remain available.

> Korean company disclosures in English, in your AI — the MCP that lets ChatGPT and Claude read DART filings, financial statements and business segments the moment you ask. Source-backed, with the United States (SEC EDGAR), Japan (EDINET) and Europe (ESEF) as comparison counterparts. Free tier, no card. Information only, not investment advice.

FinBridge is an MCP server (https://mcp.gronox.kr/mcp), not a chatbot. Connect it to the model you already use — Claude, ChatGPT, Cursor or any MCP client — and every number below is one question away, with the filing it came from. Korea is the differentiator: most vendors skip or paywall Korean data; FinBridge serves DART filings, K-IFRS statements and business segments first-class, in the same schema as US data. Korean and US price delivery is paused (see the notice above); prices are planned, not offered today.

Coverage: 3,521 Korean and 7,868 US listed stocks, plus Japan and Europe as comparison counterparts; 27 MCP tools. Statements follow the local accounting standard (K-IFRS, US-GAAP, J-GAAP/IFRS, TW-IFRS). Figures are nightly snapshots of the primary source and may be restated by the filer.
