cryptodata-mcp

Production-ready Model Context Protocol (MCP) server delivering specialized crypto market microstructure, derivatives, order flow CVD/OI regime classification, fear & greed sentiment, and whale tracking context.

Designed specifically to complement charting tools (like TradingView) with real-time data that traditional charts cannot offer.

Features & Tools

Tool

Parameters

Description

get_orderflow_and_cvd_context

ticker (required, e.g. "BTC"), period ("15m" | "1h" | "4h" | "1d", default "4h")

Evaluates market conditions against the 9-State Order Flow Matrix using live Price, OI, Spot CVD, and Futures CVD deltas. All four legs span the same 10-candle lookback of the requested period.

get_basis

pair (default "BTCUSDT"), contract_type ("PERPETUAL" | "CURRENT_QUARTER" | "NEXT_QUARTER", default "PERPETUAL")

Returns Futures vs. Spot Basis value, Basis %, and Contango / Backwardation / Parity classification. Annualized basis is reported for dated contracts only (scaled by 365/days-to-expiry); it is undefined for perpetuals.

get_funding_rate

ticker (default "BTC")

Returns the current funding rate %, annualized rate %, next settlement time, and trend direction. The settlement interval is read from the venue (8h, 4h, …) rather than assumed.

get_buy_sell_volume_ratio

ticker (default "BTC"), period ("15m" | "1h" | "4h" | "1d", default "4h"), market_type ("spot" | "futures" | "both", default "both")

Taker Buy/Sell volume in USD, Buy/Sell Ratio (> 1.05 = aggressive buyers, < 0.95 = aggressive sellers), Aggressor Delta, and Bias classification.

get_fear_and_greed_index

limit (1-365, default 7)

Global Crypto Fear & Greed Index score (0-100), classification, and multi-day historical trend.

get_whale_and_exchange_flows

ticker (default "BTC"), timeframe ("1h" | "4h" | "12h" | "24h" | "7d" | "1w" | "30d" | "all", default "24h"), min_usd_value (default 1,000,000), max_pages (1-20, default 5), wait_for_login_seconds (0-120, default 3)

Always opens Arkham Explorer — reusing an already-open Arkham window when one is on the debug port, launching one only if not — and scrapes both the Transfers and Trades tabs filtered to the timeframe and USD threshold. Also returns the exchange tape (spot/futures volume over the full timeframe, plus large trades from the recent tape).

open_arkham_whale_tracker

token (required — "BTC", "ETH", "solana"), tab ("transfers" | "trades" | "both", default "both"), timeframe (default "24h"), min_usd_value (default 100,000), max_pages (1-20, default 3), wait_for_login_seconds (0-120, default 3)

Launches Chrome via CDP against https://arkm.com/explorer/token/<token> and scrapes live whale transfers & trades.

Data-availability contract

No tool substitutes placeholder values. When an upstream venue cannot be reached, the tool returns an explicit UNAVAILABLE / INSUFFICIENT DATA result naming the failure, rather than a zero or a default that would be indistinguishable from a real reading. Likewise, a failed Arkham scrape is reported as a scrape failure — never as an absence of whale activity.

📊 Order Flow & CVD Cheatsheet Matrix (9 Market Regimes)

The internal matrix evaluator (src/utils/matrixEvaluator.js) classifies live market conditions into one of 9 strategic regimes. CVD is classified as an imbalance ratio against total taker volume (±2% standard, ±8% sharp), so the thresholds carry the same meaning for BTC and for a small cap. A component pointing the opposite way to a regime's specification counts against that regime, and when several regimes score equally the result is reported as AMBIGUOUS rather than silently resolved.

🌐 Arkham Intelligence Whale Tracker Launcher

The server includes an automated browser launcher that opens a dedicated new window of Google Chrome navigating directly to Arkham Token Explorer:

  • URL Format: https://arkm.com/explorer/token/<token_name>

  • Token slugs are resolved dynamically (BTC -> bitcoin, ETH -> ethereum, SOL -> solana).

  • Provides direct tab focus for Transfers and Trades.

Both get_whale_and_exchange_flows and open_arkham_whale_tracker drive this browser. They reuse an already-open arkm.com tab on the debug port when one exists — which is the fast path, and the one that carries your logged-in Arkham session. A browser is launched only when no usable tab is found.

⚠️ A launch opens a visible window using an isolated profile in your temp directory (not your everyday Chrome profile), so you will need to log into Arkham inside it — raise wait_for_login_seconds on that first run. Only a browser this server itself spawned is ever terminated; your own Chrome is left alone.

Coverage caveat: scraping walks max_pages pages per tab from the most recent, and Arkham's own value filter is not driven programmatically. A high min_usd_value on a busy token may therefore return few or no rows simply because the large ones sit deeper than the scanned depth — raise max_pages. The output always states how many pages were scanned, and a failed scrape is reported as a failure rather than as an absence of activity.

The CDP port defaults to 9224 and can be overridden with the ARKHAM_CDP_PORT environment variable.

🛠️ Installation & Setup
