# 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.

33 read-only tools over the free, no-auth public JSON API of [bykaranteli.com](https://bykaranteli.com/developers). 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).

## Hosted endpoint (no install)

Paste `https://mcp.bykaranteli.com` as a custom connector in any MCP-capable
assistant. Same 33 tools, nothing to install, no key.

## 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](https://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](https://bykaranteli.com/risk-guide).

## Development
