bykaranteli-mcp

MCP (Model Context Protocol) server for live crypto derivatives data: funding rates, cross-exchange funding arbitrage, open interest pressure, Fear & Greed, BTC dominance and a verified signal track record.

Backed by the free, no-auth public JSON API of bykaranteli.com. No API key, no account, no rate-limit registration. Data covers Binance USDT-M perpetuals (funding arbitrage additionally compares OKX, Bybit, Gate, HTX and BingX).

Data notes

• Signal performance is a live-only track record: real published signals with SHA-256 receipts, evaluated net of fees, slippage and funding. Never backtests. Verify any signal at bykaranteli.com/verify.
• Funding, OI and pressure data refresh every 15 to 30 minutes; indices every 30 minutes.
• Nothing here is financial advice. See bykaranteli.com/risk-guide.
