FinBridge MCP — Korean + US market data for AI agents

Remote MCP server (Streamable HTTP): https://mcp.gronox.kr/mcp

FinBridge gives your AI assistant (Claude, ChatGPT, Gemini CLI, Cursor — any MCP client) unified access to Korean and US market data on one normalized schema. It is the only place that serves the Korean market as a first-class citizen: DART filings, corporate-action-adjusted prices, 1,300+ Korean ETFs and named screeners — data that global providers either skip or gate behind $149/mo tiers.

Licensing-clean by design: FinBridge serves only data it may redistribute — OpenDART, SEC EDGAR, data.go.kr (Financial Services Commission), FRED public series, and exchange public data via ccxt. No scraped or license-encumbered feeds.
