What is BASTION?

BASTION is a Model Context Protocol (MCP) server that turns any Claude agent into a professional crypto trading desk. Through a single MCP connection (Streamable HTTP or SSE), your agent gains 147 specialized tools for market data, derivatives analytics, on-chain intelligence, AI risk evaluation, portfolio management, and autonomous trade execution.

The core engine is a fine-tuned 72B parameter model running on a 4x RTX 5090 GPU cluster, analyzing 560+ real-time signals per 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 work without an API key. You only need a key for portfolio access and trade execution.
