Overview

AI-generated overview

Remote MCP server for pay-per-call crypto quant tools: survivorship-bias-free backtests, daily market signals, strategy optimization and token scam checks.

What you can do
  • Run backtests of breakout, momentum, dip-buy or MA-trend rules on 399 Coinbase pairs using a point-in-time universe.
  • Get a daily market regime summary: BTC/ETH versus moving averages, breadth, breakout watchlist and strategy gate signals.
  • Screen tokens on Base, Ethereum or Solana for honeypot, tax, mint/blacklist and lookalike risks.
  • Optimize strategy parameters across up to 50 combinations and flag overfitting.
  • Fetch a survivorship-free top-N coin list for any past date.
  • Check schemas, prices and argument validity, and pull free delayed samples before paying.
When to use it
Useful when you want an assistant to evaluate crypto trading strategies or screen tokens without building your own data pipeline, and you accept paying small per-call fees in USDC. The free sample and validation tools let you judge output quality first.
Requirements
A remote streamable HTTP endpoint; no local package or runtime. No account or API key is declared. Paid tools require an x402-aware MCP client that can pay in USDC on Base mainnet; free tools and samples need no payment. Network access to the hosted service.
Before you install
Paid tools cost USDC per call (for example 0.50 for optimize_strategy), so an assistant that retries can spend money; use the validate tools first. Payments go through x402 on Base mainnet, which involves a wallet. Results are informational only and not financial advice. Free samples are rate limited per client.

Installation

In SourceWeft

  1. Open Grok Crypto Quant API in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.fly.grok-backtest-api%2Fcrypto-quant/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

backtest

Crypto strategy 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.

Parametersendfeestartslippagestrategyrequireduniverseinclude_tradesinitial_capital

market_signals

Daily crypto 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.

Parameterstop_n

token_check

Token scam / honeypot risk 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.

Parameterschainrequiredaddressrequired

optimize_strategy

Robust strategy parameter optimiser

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.

Parametersendfeegridrequiredstartrank_byslippagestrategyrequireduniverseinitial_capital

universe_snapshot

Point-in-time top-N coin universe

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.

Parametersdatetop_nmin_age_daysmin_avg_dollar_volume

signals_sample

Market signals, delayed free 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.

Takes no parameters.

backtest_sample

Crypto backtest, free 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.

Parametersdaysstrategyrequired

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
