[!IMPORTANT]Zero install required.BASTION is a cloud-hosted MCP server. Connect with one command and your Claude agent instantly gets 147 real-time crypto tools. No dependencies, no Docker, no API wrappers.

BASTION is aModel Context Protocol (MCP) serverthat turns any Claude agent into a professional crypto trading desk. Through a single MCP connection (Streamable HTTP or SSE), your agent gains147 specialized toolsfor market data, derivatives analytics, on-chain intelligence, AI risk evaluation, portfolio management, and autonomous trade execution.

The core engine is afine-tuned 72B parameter modelrunning on a 4x RTX 5090 GPU cluster, analyzing560+ real-time signalsper evaluation. It doesn't just return data — it returns structured risk assessments with reasoning chains, confidence scores, and explicit action recommendations.

You: "Check my BTC long, I'm worried about the funding spike" Claude: [Calls bastion_evaluate_risk, bastion_get_funding_rates, bastion_get_liquidations] Your BTC LONG is at moderate risk (52/100). Here's why: Funding at 0.035% is elevated but not extreme. However, there's a $2.1B liquidation cluster at $94,200 — just 3.8% below current price. OI rose 4.2% without corresponding volume, suggesting overleveraged longs. CVD is diverging bearish on the 1h. Recommendation: TP_PARTIAL — Take 50% profit here. Move stop to breakeven on the remainder.

[!TIP] All market data, derivatives, on-chain, macro, and AI tools workwithout an API key. You only need a key for portfolio access and trade execution.

You: What's the current state of BTC? Give me a quick overview. Claude: [bastion_get_price] [bastion_get_market_data] [bastion_get_fear_greed] Bitcoin Overview: Price: $98,420 (+2.3% 24h) 24h Volume: $48.2B Market Cap: $1.94T Dominance: 56.8% Fear/Greed: 72 (Greed) BTC is showing strong momentum approaching the $100K psychological level. Volume is elevated and sentiment is firmly in Greed territory.

You: Check all my positions and evaluate risk. Claude: [bastion_get_positions] [bastion_evaluate_all_positions] 3 open positions evaluated: 1. BTC/USDT LONG · 5x · Entry $96,200 · Now $98,420 (+2.3%) Risk: 35/100 (Low) → HOLD OI rising with price confirms genuine demand. 2. ETH/USDT LONG · 3x · Entry $2,680 · Now $2,645 (-1.3%) Risk: 55/100 (Moderate) → HOLD with caution ETH/BTC ratio declining signals relative weakness. 3. SOL/USDT SHORT · 2x · Entry $195.40 · Now $198.20 (-1.4%) Risk: 68/100 (Elevated) → REDUCE_SIZE Rising OI + positive CVD + whale accumulation detected.

You: Any funding rate arb opportunities right now? Claude: [bastion_get_funding_rates] [bastion_get_funding_arb] Top Opportunity: BTC/USDT Spread: Bybit vs dYdX = 0.043% per 8h (47.1% annualized) Strategy: → Long on dYdX (collect 0.008%) → Short on Bybit (pay 0.035%) → Net: Collect spread while delta-neutral

You: What are the whales doing with ETH right now? Claude: [bastion_get_whale_activity] [bastion_get_exchange_flow] Whale Activity — ETH (last 24h): → 3 large wallets accumulated 12,400 ETH ($32.8M) → Exchange outflow exceeds inflow by 8,200 ETH → Top 100 wallets increased holdings by 0.3% Interpretation: Smart money is accumulating. Exchange outflow suggests coins moving to cold storage (bullish signal).
