Curistat MCP Server

Futures-specific volatility intelligence for AI agents via the Model Context Protocol.

The first MCP server dedicated to futures volatility analytics. Provides forecasts, regime detection, rare signals, directional bias, and research tools for ES, NQ, and related products.

Quick Start

1. Install

pip install curistat-mcp

2. Get a Curistat API key

Sign up at curistat.com/developer and generate an API key.

3. Configure Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "curistat": {
      "command": "python",
      "args": ["-m", "curistat_mcp"],
      "env": {
        "CURISTAT_API_KEY": "cst_agent_your_key_here"
      }
    }
  }
}

Restart Claude Desktop. You can now ask Claude questions like:

• "What's the volatility forecast for ES today?"
• "Are there any rare signals firing for NQ?"
• "Show me the economic calendar for next week"
• "Find historical days similar to today for ES"
