Name: 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 14 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)
Multi-timeframe	4H EMA alignment — ±3 TSS bonus/penalty based on 4H EMA-20 vs EMA-50
RSI Divergence	Bullish / bearish / none — price vs RSI extremes over last 30 bars
OBV Trend	On-Balance Volume direction (rising / falling / flat) — ±2 TSS confirmation bonus
Funding Rate	Current USDT-M perpetual funding rate — positive extremes = over-leveraged longs
Regime	Low / mid / high volatility — classified by 3-state GaussianHMM (falls back to rule-based)
TSS	Trend Strength Score — 0–100 composite (40% trend + 30% momentum + 30% RS ± MTF ± OBV)

rank_coins

Pass a list of symbols and get them back ranked by TSS. Runs in parallel (up to 8 workers) for fast results on large lists. Each result includes TSS, regime, EMA alignment, 4H MTF alignment, RSI divergence, OBV trend, funding rate, RSI-14, ADX-14, and RS vs BTC.

top_coins

No symbol list needed. Fetches the top 50 coins by market cap from CoinGecko and returns them ranked by TSS. Smart filtering automatically removes:

• Stablecoins (USDT, USDC, DAI, etc.)
• Wrapped / synthetic tokens (WBTC, WETH, stETH, cbBTC, etc.)
• Low-liquidity coins with < $10M daily volume

correlate_coins

Compute pairwise Pearson correlation of 30-day daily returns across 2–20 coins. Returns the full correlation matrix, high-correlation clusters (>0.85), and uncorrelated pairs (<0.30) — useful for portfolio diversification analysis.

market_context

Macro market signals to frame individual coin analysis. Uses CoinGecko global data, DefiLlama stablecoin supply, and Alternative.me Fear & Greed Index. 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 power)
Fear & Greed	Alternative.me index (0–100) — extreme fear/greed applies ±5 modifier to MRS
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

Watchlist tools

Persistent coin lists stored in SQLite (~/.cryptoscholar/watchlist.db).

Tool	What it does
watchlist_add	Add symbols to a named list (creates the list if needed)
watchlist_remove	Remove symbols; also clears their alerts
watchlist_show	Show all symbols + configured alerts for a list
watchlist_lists	List all named watchlists with symbol counts
watchlist_scan	Run a full TSS analysis on every coin in the list — parallel digest view
alert_set	Set a tss_above, tss_below, or regime_change alert on any symbol
alert_check	Fetch live TA for all alerted symbols, report which alerts fired, update baseline

train_regime_model

Manually trigger a retrain of the HMM volatility regime model on fresh BTC price history. The model auto-retrains every 7 days automatically — use this after a major market structure shift to force an immediate update. Accepts an optional force=True flag to bypass the 7-day cooldown.

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

---

What's new in v0.6.0

• GaussianHMM regime classification — volatility regime is now classified by a 3-state Hidden Markov Model trained on three features: 20-day historical volatility (hv_20), normalised ATR-14, and Bollinger Band width. The model learns what low/mid/high volatility looks like in feature space rather than applying fixed percentile thresholds.
• Auto-retrains every 7 days — on the first analyze_coin or rank_coins call after the threshold, the model retrains on BTC price history without any manual intervention.
• Rule-based fallback — if no model exists yet, or if the HMM prediction fails for any reason, the original ATR + BBW percentile classifier is used silently.
• regime_source field — analyze_coin now returns regime_source: "hmm" or "rule_based" so you can see which classifier was used.
• train_regime_model tool — force a manual retrain at any time (e.g. after a major market structure shift). Use force=True to bypass the 7-day cooldown.
• Model persisted to disk — trained model stored at ~/.cryptoscholar/hmm_model.pkl; survives server restarts.

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"
• "Show me the top 50 coins ranked 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"
• "How correlated are BTC, ETH, SOL, and AVAX over the last month?"
• "Add BTC, ETH, and SOL to my main watchlist"
• "Set an alert on BTC if TSS drops below 35"
• "Check my alerts"
• "Give me the digest for my main watchlist"

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, OBV trend, funding rate, 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.

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 65 major coins for instant resolution — the full top-50 market cap universe including BTC, ETH, SOL, BNB, XRP, ADA, AVAX, DOGE, LINK, DOT, SUI, TIA, WIF, BONK, and more. 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.
