This is the official Model Context Protocol (MCP) proxy client for Polyball.

It acts as a lightweight, transparent bridge that connects AI desktop applications (like Claude Desktop and Cursor) to the remote Polyball backend hosted on Railway via Server-Sent Events (SSE).

🚀 Quick Start for Claude Desktop

You do not need to clone the repository, install Python, or set up any local environment variables. Everything runs securely on the remote server.

Just open your claude_desktop_config.json file (usually located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS) and add the following configuration:

{
  "mcpServers": {
    "polyball": {
      "command": "npx",
      "args": [
        "-y",
        "polyball-mcp"
      ]
    }
  }
}

Restart your Claude Desktop, and you will instantly have access to the Polyball Debate Engine and Polymarket integration!

🛠️ Features

• Zero-Config: No local .env setup required. API keys are safely managed on the Railway server.
• Universal Access: Uses the standard npx ecosystem supported by Claude Desktop and Cursor.
• Real-Time Data: Queries Polymarket market values, live predictions, and Solana gate validations directly.

🔗 Architecture

• Client (This Package): A lightweight Node.js wrapper using @modelcontextprotocol/sdk.
• Server (Backend): A Python FastMCP server hosted on Railway.
