bykaranteli-mcp

MCP (Model Context Protocol) server for live crypto derivatives data: funding rates, cross-exchange funding arbitrage, open interest pressure, liquidations, options, ETF flows, Fear & Greed and BTC dominance.

45 read-only tools over the public JSON API of bykaranteli.com. Since 2026-09-17 the API asks programs for an account key: a free key comes with any verified account at https://bykaranteli.com/dashboard/api (30 requests a minute, public depth), and the Builder, Business and Scale plans raise the rate and unlock member depth (LiqMap on seven timeframes, 5-minute series, the x402 catalog included). Set it as BYKARANTELI_API_KEY. Data covers Binance USDT-M perpetuals (funding arbitrage additionally compares OKX, Bybit, Gate, HTX, BingX, Kraken, MEXC and Bitget).

Hosted endpoint (no install)

Paste https://mcp.bykaranteli.com as a custom connector in any MCP-capable assistant. Same 45 tools, nothing to install. Without a key it runs on the shared Free pool; a connector header Authorization: Bearer bk_... (Builder and above) brings your own rate limit and member depth.
