# 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.

67 read-only and account tools over the public JSON API of [bykaranteli.com](https://bykaranteli.com/developers): the market data tools only read, and the alert and watchlist tools act on your own account through your key ([Account tools](#account-tools-alerts-and-watchlist)). Since 2026-09-10 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 and 15,000 a month, public depth), and the Builder, Business and Scale plans raise the rate and the monthly fair use and unlock member depth (LiqMap on seven timeframes, 5-minute series) and a monthly allowance of x402 catalog calls within each plan's history window ([Plans and paid depth](#plans-and-paid-depth)). Set it as `BYKARANTELI_API_KEY`. Data covers Binance USDT-M perpetuals; funding arbitrage, liquidations, order book depth, options, positioning and insurance funds add the other venues each board lists on bykaranteli.com/coverage.

## Hosted endpoint (no install)

Paste `https://mcp.bykaranteli.com` as a custom connector in any MCP-capable
assistant. The same tools, nothing to install. Every tool call needs your
account key (free at <https://bykaranteli.com/dashboard/api>); connecting and
listing the tools work without one. The key travels one of three ways:

- the request header `x-api-key: bk_...` (claude.ai custom connectors, Cursor,
  Claude Code);
- the request header `Authorization: Bearer bk_...`;
- the address `https://mcp.bykaranteli.com/?key=bk_...` for clients that cannot
  send headers (ChatGPT). Treat that address like a password and revoke the key
  if it leaks.

Or sign in with OAuth 2.1 where the client offers it (claude.ai custom
connectors: Authentication, Sign in; ChatGPT connectors: OAuth): the client
registers itself (RFC 7591, PKCE S256), you approve it once on bykaranteli.com
and it runs on a key of your own account, which the Data and API page lists
under connected apps. Discovery:
<https://mcp.bykaranteli.com/.well-known/oauth-protected-resource>.

A free account covers the API and the hosted MCP on one monthly counter;
Builder and above bring higher rates and member depth.
