# 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, the x402 catalog included in the monthly fair use). 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.

All market answers are JSON and carry a `generatedAt` timestamp, a `source` URL to the human-readable page and a `provenance` block: `source_page`, `api_path`, the answer's own `generated_at`, `fetched_at`, and when the answer carries them the `venues` behind the number, `coverage` (`full`, `sampled` or `mixed`), `stale_venues` and `recorded_since`, plus the `proof` page (<https://bykaranteli.com/proof>). A field the answer does not carry is left out, never filled in. Symbols accept both `BTCUSDT` and bare `BTC`.
## Account tools (alerts and watchlist)
These tools read and change your own ByKaranteli account with the same key: the alert recipes that notify you on Telegram, email, push or webhook, and your watchlists. They never trade, move funds or touch another account.
| Tool | What it does |
|---|---|
| `parse_alert_text` | Turns "BTC funding above 0.05%" or "tell me when ETH drops 5% in a day" into the exact recipe, with a confidence and what the text left open. Rule based; saves nothing, never invents a threshold. |
| `list_alert_recipes` | Lists your alert recipes with their conditions, scope, channels and when each last fired. |
| `create_alert_recipe` | Saves an alert recipe (writes to your account). |
| `delete_alert_recipe` | Deletes one of your alert recipes by id (writes to your account). |
| `list_watchlists` | Lists your watchlists and the symbols on each. |
| `add_watchlist_symbol` | Adds a symbol to your default list or the list you name (writes to your account). |
| `remove_watchlist_symbol` | Removes a symbol from a list (writes to your account). |
| `list_tracked_addresses` | Lists the Hyperliquid addresses you follow, with their last positions (reads your account). |
| `add_tracked_address` | Follows a Hyperliquid address for position alerts (writes to your account; Terminal and above). |
| `remove_tracked_address` | Stops following an address (writes to your account). |
- The write tools carry `readOnlyHint: false` (and `destructiveHint: true` for the two that remove something), so clients that ask before a change will ask.
- How many recipes an account keeps follows its plan; past it, `create_alert_recipe` answers with the limit instead of saving.
- Every call counts on the key's plan like any other request; writes are also rate limited per key, and each write is recorded on the account with the key that made it.
- Recipes and watchlist changes show up at once on <https://bykaranteli.com/dashboard/alerts> and <https://bykaranteli.com/dashboard/watchlist>.
## Configuration
| Env var | Default | Purpose |
|---|---|---|
| `BYKARANTELI_API_KEY` | none | Account key (`bk_...`) sent as `Authorization: Bearer`. Free at <https://bykaranteli.com/dashboard/api>; required for programs from 2026-09-10 |
| `BYKARANTELI_BASE_URL` | `https://bykaranteli.com` | Override the API host (testing only). The key is sent to whatever host this names, so point it only at a server you trust. |
