CryptoScholar

Crypto technical analysis, directly inside Claude. CryptoScholar is a Model Context Protocol (MCP) server that gives Claude real-time TA capabilities — no chart-switching, no copy-pasting data, no context loss.

Ask Claude "Is SOL set up for a swing trade?" and it fetches live data from Binance, runs a full indicator suite, scores it, and delivers a grounded bull/bear debate — all in one response.

What it does

CryptoScholar exposes 4 MCP tools that Claude can call natively:

analyze_coin

Full technical analysis snapshot for any coin. Fetches 300 days of real OHLCV candles from Binance (with CoinGecko fallback) and computes:

Indicator	Details
Trend	EMA-20, EMA-50, EMA-200 alignment + weekly EMA slope
Momentum	RSI-14, MACD (line / signal / histogram), ADX-14
Volatility	ATR-14, Bollinger Band width, Historical Volatility (20-day annualised)
Relative Strength	Coin vs BTC (20-day ratio change)
Regime	Low / mid / high volatility classification
TSS	Trend Strength Score — 0–100 composite (40% trend + 30% momentum + 30% RS)

rank_coins

Pass a list of symbols and get them back ranked by TSS. Useful for quickly identifying the strongest setups across your watchlist.

market_context

Macro market signals to frame individual coin analysis. Uses CoinGecko global data and DefiLlama stablecoin supply. Returns:

Signal	Description
BTC dominance	Current % and 30-day change — falling = capital rotating to alts
ETH/BTC ratio	20-day trend — rising = broadening rally
TOTAL3	Altcoin market cap (ex-BTC, ex-ETH) 30-day change
Stablecoin supply	Total stablecoin market cap and 30-day trend (rising = more buying powder)
ARS	Altcoin Rotation Score 0–100 — how favourable macro is for alts
MRS	Market Readiness Score 0–100 — overall market readiness for upside moves

debate

Claude reads the live TA data and generates a structured bull/bear debate grounded in actual indicator values — not hallucinated opinion. Returns:

• Bull case — what the technicals say in favour
• Bear case — what could go wrong
• Bottom line — one-sentence synthesis

No API key required for market data. Only ANTHROPIC_API_KEY is needed for the debate tool.

What's new in v0.2.0

• Real OHLCV candles — price data now comes from Binance's public API (300 days, no API key required). CoinGecko is kept as automatic fallback for any symbol not on Binance. The analyze_coin output includes a data_source field so you can see which was used.
• market_context tool — a new fourth tool that gives Claude a macro picture before diving into individual coins. Returns BTC dominance trend, ETH/BTC ratio, TOTAL3 altcoin market cap, and stablecoin supply from DefiLlama.
• ARS (Altcoin Rotation Score) — 0–100 composite scoring whether the macro environment favours alts. Factors in BTC dominance direction, ETH/BTC trend, and TOTAL3 momentum.
• MRS (Market Readiness Score) — 0–100 overall market readiness for upside. Weighted: 40% BTC trend + 30% ARS + 30% stablecoin supply trend.

Quick start

Requirements: Python 3.11+

git clone https://github.com/cryptographer11/cryptoscholar.git
cd cryptoscholar
make install
cp .env.example .env
# Add your ANTHROPIC_API_KEY to .env (only needed for debate tool)
cryptoscholar

Add to Claude Code

In ~/.claude/.mcp.json:

{
  "mcpServers": {
    "cryptoscholar": {
      "command": "python",
      "args": ["-m", "cryptoscholar"],
      "env": {
        "ANTHROPIC_API_KEY": "your_key_here"
      }
    }
  }
}

Restart Claude Code. You can now ask:

• "Analyze BTC for me"
• "Rank ETH, SOL, AVAX, and LINK by trend strength"
• "What does the macro market look like right now?"
• "Give me the bull and bear case for DOGE based on current TA"

Screenshots

Ranking BTC, ETH, and XRP by Trend Strength Score — then drilling into the bear case for XRP

rank_coins scores each coin across trend, momentum, and relative strength vs BTC and returns them sorted by TSS. Here BTC leads at 63.7, ETH at 53.0, and XRP trails at 47.8 — all in low_vol regime. Asking for the XRP bear case immediately after surfaces the specific technical reasons: a steepest weekly EMA slope, faltering MACD, and ETH underperformance vs BTC flagged as early institutional exit pressure.

---

Full technical analysis snapshot for SOL — indicators, scoring, and bear case in one response

analyze_coin returns a structured breakdown covering EMA stack alignment, RSI, MACD, ADX, ATR, Bollinger Band width, and relative strength vs BTC — all computed from 300 days of live Binance candles. Claude then reads the raw indicator values to generate a grounded bear case: EMA-200 resistance, weekly slope steepening, and MACD crossdown risk. No chart-switching, no copy-pasting — the full TA context is already in Claude's window.

debate("SOL")

{

  "bear_case": "Historical volatility at 68% is elevated, and Bollinger Band width is widening — conditions that often precede sharp reversals. A break below EMA-20 would invalidate the current trend structure.",
  "bottom_line": "Technicals are constructive for continuation but volatility is high; position sizing should reflect the risk."

Configuration

Variable	Default	Description
ANTHROPIC_API_KEY	—	Required for the debate tool
CRYPTOSCHOLAR_MODEL	claude-haiku-4-5-20251001	Claude model used for debates (swap for Sonnet/Opus for deeper analysis)
CRYPTOSCHOLAR_LOG_DIR	/tmp	Directory for rotating log files

Supported coins

CryptoScholar works with any coin listed on CoinGecko or Binance — just pass the ticker symbol. No configuration needed.

A built-in symbol map covers 20 major coins for instant resolution (BTC, ETH, SOL, BNB, XRP, ADA, AVAX, LINK, DOGE, DOT, MATIC, UNI, ATOM, LTC, BCH, NEAR, APT, ARB, OP, INJ). For anything outside that list, CryptoScholar automatically queries CoinGecko's search API to resolve the symbol and falls back to CoinGecko OHLCV if the coin isn't available on Binance.

In practice: if it trades somewhere and has a CoinGecko listing, it will work.
