finbridge

Official Korean company data for AI clients. FinBridge collects DART filings and financial statements every night (the filings feed every 5 minutes), adds plain-language English summaries of material disclosures, and serves them to ChatGPT, Claude, Cursor or any MCP client, and over a REST API. US (SEC EDGAR), Japan (EDINET), Taiwan and Europe (ESEF) statements are there as comparison counterparts.

• MCP endpoint (Streamable HTTP): https://mcp.gronox.kr/mcp
• REST API: https://mcp.gronox.kr/api/v1 · OpenAPI 3.1: https://mcp.gronox.kr/api/v1/openapi.json
• Free plan, no card: 10 calls a day across the web and your AI, every tool, the last 4 fiscal years. Paid plans buy volume and history depth. Current plans: https://finbridge.gronox.kr/pricing

Official sources only, and only sources we may redistribute: OpenDART, SEC EDGAR, EDINET, TWSE/TPEx OpenAPI, ESEF filings and data.go.kr (Financial Services Commission). Every answer names its source and as-of date, and every company carries a page_url to a public page with the filing behind each number.

Quick start

Claude (claude.ai / Desktop)

Settings → Connectors → Add custom connector → https://mcp.gronox.kr/mcp — sign in with Google, no key needed. Then, in each new chat, open + → FinBridge to turn it on (connectors are off per conversation until you do) and ask.

Claude Code

claude mcp add --transport http finbridge https://mcp.gronox.kr/mcp --header "Authorization: Bearer smcp_..."

Get a key at https://finbridge.gronox.kr/login (Google sign-in, issued instantly).

ChatGPT (developer mode)

Settings → Apps & Connectors → Advanced → Developer mode → Create connector with the URL above and your smcp_ key as the access token.

Any MCP client (Gemini CLI, Cursor, …)

{"mcpServers": {"finbridge": {"httpUrl": "https://mcp.gronox.kr/mcp",
  "headers": {"Authorization": "Bearer smcp_..."}}}}

REST (no MCP client)

curl -H "Authorization: Bearer smcp_..." https://mcp.gronox.kr/api/v1/companies/kr/005930/financials
curl -H "Authorization: Bearer smcp_..." "https://mcp.gronox.kr/api/v1/companies/us/AAPL/peers?limit=5"
curl -H "Authorization: Bearer smcp_..." "https://mcp.gronox.kr/api/v1/companies/eu/NL0010273215/peers?limit=5"   # Europe by ISIN: statements-based peers, no prices (EU groups all IT/electronics together, so treat the list as a starting point)

Endpoints: /companies/{market}/{symbol} (profile) · /financials · /peers. /valuation and /prices answer with the pause notice. Same key, same quota, same depth as MCP.

Built-in prompts

FinBridge registers three MCP prompts, so you can start without typing a question. In Claude.ai or Claude Desktop, turn FinBridge on in the chat (+ → FinBridge), then open + → FinBridge again and pick a prompt; in Claude Code type the slash command. Clients that don't list prompts (Cursor, ChatGPT developer mode): paste the one-liner.

Prompt	What it does	Claude Code	Paste instead
This week's filings	This week's material filings for the companies you follow (or one market's if you follow none), grouped by company with each filing's figures and link	/mcp__finbridge__weekly_watchlist kr	"Show this week's FinBridge filings for the companies I follow, grouped by company, facts only."
Company check-up	One company, facts only: four annual statements, comparison references, recent filings and insider trades, every number dated	/mcp__finbridge__company_checkup 005930	"Give me a FinBridge check-up of Samsung Electronics (005930) with data_as_of dates."
First three questions	A one-minute tour: a company's recent filings, this month's treasury-share announcements, a Korea–US financials comparison	/mcp__finbridge__first_questions	"I just connected FinBridge — answer its three starter questions and show which tool you used."

Good first questions

1. "What did Samsung Electronics disclose in the last 30 days? Summarize the material filings in English."
2. "Which Korean listed companies announced treasury-share purchases this month?"
3. "Compare SK hynix and Micron on revenue and operating margin over the last three years."

Notes

• Statements are a nightly snapshot (the filings feed refreshes every 5 minutes).
• Statements follow the local accounting standard (K-IFRS, US-GAAP, J-GAAP/IFRS, TW-IFRS), so cross-market ratios are approximations.
• Information only, not investment advice: no ratings, target prices or buy/sell views.
• This repository is the public listing (registry manifest server.json) for the hosted service; the server itself is not open source.
