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.

Quick Start

Claude Code — One Command

# Streamable HTTP (recommended)
claude mcp add bastion-mcp --transport http https://bastionfi.tech/mcp/stream

# Or legacy SSE
claude mcp add bastion-mcp --transport sse https://bastionfi.tech/mcp/sse

That's it. Restart Claude Code. All 147 tools are live.

Claude Desktop — One Config

Add to claude_desktop_config.json (macOS ~/Library/Application Support/Claude/ · Windows %APPDATA%\Claude\):

{
  "mcpServers": {
    "bastion": {
      "type": "streamable-http",
      "url": "https://bastionfi.tech/mcp/stream"
    }
  }
}

Or use legacy SSE transport

{
  "mcpServers": {
    "bastion": {
      "type": "sse",
      "url": "https://bastionfi.tech/mcp/sse"

  }
}

Python MCP Client

from mcp import ClientSession
from mcp.client.streamable_http import streamablehttp_client

# Streamable HTTP (recommended)
async with streamablehttp_client("https://bastionfi.tech/mcp/stream") as (read, write, _):
    async with ClientSession(read, write) as session:
        await session.initialize()

        result = await session.call_tool("bastion_evaluate_risk", {
            "symbol": "BTC",
            "direction": "LONG",
            "entry_price": 96200.0,
            "current_price": 98400.0,
            "leverage": 5,

from mcp.client.sse import sse_client

async with sse_client("https://bastionfi.tech/mcp/sse") as (read, write):
    async with ClientSession(read, write) as session:
        await session.initialize()
        result = await session.call_tool("bastion_evaluate_risk", {...})
