Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
validate
validate_backtest
Free: check backtest arguments (same as the paid `backtest` tool) before paying.
validate_optimize
Free: check optimize_strategy arguments and count grid combos before paying.
validate_token_check
Free: format-check a token_check request (no on-chain lookups).
validate_universe
Free: check universe_snapshot arguments (date in range, enough history) before paying.
backtest
backtest
Backtest crypto strategies on 399 Coinbase coins without survivorship bias. DIY backtests usually use today's coin list, so dead coins vanish and returns are overstated; this rebuilds the universe from each past day's top coins. Breakout, momentum, dip-buy or MA-trend rules on daily data with fees, slippage, H1/H2 split and a luck flag. No data fetching or backtest code on your side. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_backtest. Free sample: backtest_sample.
backtest_sample
Free sample of the paid `backtest` tool on the same survivorship-bias-free engine: any strategy, point-in-time top-10 universe, window = last `days` (14..90) completed days, summary only. Full version: backtest ($0.05). Limit 30/hour per client.
health
health
Free: service status, prices, network and data range.
market
market_signals
Daily crypto market regime in one call: BTC/ETH vs 20/50-day MAs, breadth of the point-in-time top-N (no survivorship bias), coins nearest a 20-day breakout, and the R1 breakout strategy's gate and entry signals. No candle fetching or indicator code. Completed UTC daily closes only. Price: $0.01 USDC per call (x402, Base mainnet). Free sample: signals_sample.
optimize
optimize_strategy
Find robust strategy params, not lucky ones: tests up to 50 combos on the same survivorship-bias-free backtester, ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most stable parameters rather than the best-fit ones. Price: $0.50 USDC per call (x402, Base mainnet). Free pre-check: validate_optimize.
schema
get_schema
Free: request schemas, examples, prices and limits for every paid tool/endpoint.
signals
signals_sample
Free, one day delayed: yesterday's full /signals result (BTC/ETH trend, breadth, breakout watchlist, R1 gate) so you can judge quality before paying. Today's result: paid market_signals ($0.01). Limit 60/hour per client.
token
token_check
Token scam check in one call instead of wiring up five data sources: honeypot sell simulation, unverified code, mint/pause/blacklist powers, taxes, upgradeable proxy, age, liquidity, fake major-token (e.g. fake USDC) lookalikes and spam-airdrop patterns. Base, Ethereum or Solana. Never visits metadata URLs. Price: $0.02 USDC per call (x402, Base mainnet). Free pre-check: validate_token_check.
universe
universe_snapshot
Survivorship-free top-N coin list for any past date: Coinbase USD pairs ranked by trailing 20-day dollar volume using only data available that day. Fixes your own backtests: picking today's top coins hides the ones that died and overstates returns. Price: $0.05 USDC per call (x402, Base mainnet). Free pre-check: validate_universe.

What can Grok Crypto Quant API do?
It exposes 13 tools, read directly from the server on our last check. Among them: backtest, backtest_sample, get_schema, health, market_signals, optimize_strategy and 7 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 Grok Crypto Quant API mostly used for?
Its tools cluster around validate and backtest. 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 Grok Crypto Quant API 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 301 ms. The bar chart above shows every period we have measured.
How do I connect Grok Crypto Quant API?
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 Grok Crypto Quant API need an API key?
No. Grok Crypto Quant API completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Grok Crypto Quant API?
It answers our handshake in 301 ms on average, which is faster than 47% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
