Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

funding
funding_events
What is burning on the crypto perpetuals funding market right now: open extreme events (|hourly rate| ≥ 0.1%/h) with peaks and receiving sides, plus the top pairs by hourly funding rate across Binance, Bybit, OKX, Bitget and Hyperliquid. Rates are predictions for the next settlement; data age ≤ ~5 min.
funding_history
Charged funding rates of one coin across all exchanges where it trades, normalized to %/hour on a common hourly grid (up to 90 days back). Shows whether the cross-exchange spread is sustained (feeds a hedged pair) or a one-off spike. Returns the curves plus the median and maximum spread.
pair
pair_briefing
Everything the radar knows about one perpetual pair in a single answer: funding rate and receiving side, time to next settlement, mark price, 24h volume, open interest with deviation from the 7-day norm, orderbook walls with break-through history, how the price usually moves around settlement, and the same coin on other exchanges. Accepts an exact symbol (BTCUSDT) or just the coin (BTC).
pair_search
Discover perpetual pairs on the radar: filter the scanner's 300 strongest pairs by coin or symbol substring, exchange, receiving side, minimum |hourly rate| or 24h volume; sort by rate, volume or open interest. Each row carries the rate in both forms, the receiving side, next settlement, volume, OI and the card link. A pair outside the 300 is reachable via pair_briefing by its exact symbol.
alert
alert_options
How to get funding alerts from the radar: the public Telegram channels (RU/EN, extreme events, delayed), the personal bot with instant alerts and custom conditions (PRO, 3-day trial for channel subscribers), and a deep link that opens the bot with the coin already set. MCP is anonymous and cannot subscribe anyone — this tool only explains and links.
radar
radar_about
Reference about Funding Radar itself: which exchanges and how many pairs it covers, how fresh the data is, a glossary of the terms used in every other answer (per-interval vs per-hour rate, predicted vs charged rate, settlement, spread, break-even), Telegram channels for RU and EN, contact email, terms for programmatic access. Call this when the user asks what this source is, how to interpret a field, where to follow it, or how to reach the team — the data tools do not repeat this.
settlement
settlement_calendar
Which notable funding settlements are coming in the next hours (default 4): pairs with |rate| ≥ 0.05%/h and volume ≥ $1M, sorted by time. Each row includes that pair's own settlement-window statistics — how much its price usually moves in the 15 minutes before the charge, with the number of observed windows.
spread
spread_pairs
Where the funding-rate spread between exchanges is widest right now: long leg on the low-rate exchange, short leg on the high-rate one. Includes the 7-day median spread, how long the spread has held above the repay-within-a-day threshold, and breakeven hours against four legs of fees (assumptions included in the answer).

Radar — questions

Answers built from our own checks of this server.

What can Radar do?
It exposes 8 tools, read directly from the server on our last check. Among them: alert_options, funding_events, funding_history, pair_briefing, pair_search, radar_about and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is Radar mostly used for?
Its tools cluster around pair and funding. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Radar working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 201 ms. The bar chart above shows every period we have measured.
How do I connect Radar?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Radar need an API key?
No. Radar completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Radar?
It answers our handshake in 201 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
