A stock-market MCP server for AI agents that need real data
If you build with Claude, Cursor, or your own agent stack, you have hit the wall: market data APIs are priced for institutions and tools are dashboards your agent cannot call. Balance Labs ships an MCP gateway instead.
Tools on the gateway
- get_market_data(symbol, interval, bars) — normalized OHLCV via a multi-source fallback loader (Yahoo → Stooq → keyed US → Eastmoney… Binance/OKX for crypto; MT5/Lighter for FX).
- stm_scan_stocks — the scanner book: signals, uPnL, quality scores across 5 markets.
- stm_research_stock — Berkshire-style research reports.
Markets: US · HK (.HK) · China A-share (.SS/.SZ) · Korea (.KS/.KQ) · India (.NS) · crypto · FX.
Access & tiers
MCP keys are tier-gated (Pro+ for stock tools, Ultra for the full trading toolset). Auth is PAT-based; the gateway speaks JSON-RPC tools/list + tools/call.
Start: Get an account then generate an MCP key from the app.
