MCP-compatible server that gives AI agents access to alternative sports data across 30+ leagues — odds, events, probabilities, settlement, and futures for prediction markets, DFS platforms, and sportsbooks.

Quick Start

# Install
cd apps/altsportsdata-mcp
uv pip install -e ../altsportsdata-sdk
uv pip install -e .

# Run (stdio)

Connect to Claude Desktop

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

{
  "mcpServers": {
    "altsportsdata": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/altsportsdata-mcp",
        "python",
        "-m",
        "altsportsdata_mcp.server"
      ],
      "env": {
        "ALTSPORTSDATA_API_KEY": "your_api_key"
      }
    }
  }
}

Restart Claude Desktop. The 29 tools will appear in the tool picker (🔧 icon).

Connect to Claude Code (CLI)

Claude Code discovers MCP servers from .mcp.json in your project root:

{
  "mcpServers": {
    "altsportsdata": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/altsportsdata-mcp",
        "python",
        "-m",
        "altsportsdata_mcp.server"
      ],
      "env": {
        "ALTSPORTSDATA_API_KEY": "your_api_key"
      }
    }
  }
}

Or register globally:

claude mcp add altsportsdata \
  --command "uv" \
  --args "run" "--directory" "/path/to/altsportsdata-mcp" "python" "-m" "altsportsdata_mcp.server" \
  --env ALTSPORTSDATA_API_KEY=your_api_key

claude mcp list

Connect to Cursor

Cursor supports MCP servers via its settings. Two options:

Option A: Project-level (.cursor/mcp.json)

Create .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "altsportsdata": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/altsportsdata-mcp",
        "python",
        "-m",
        "altsportsdata_mcp.server"
      ],
      "env": {
        "ALTSPORTSDATA_API_KEY": "your_api_key"
      }
    }
  }
}

Option B: Global (Cursor Settings)

1. Open Cursor → Settings → MCP
2. Click Add new MCP server
3. Enter:
   • Name: altsportsdata
   • Command: uv run --directory /path/to/altsportsdata-mcp python -m altsportsdata_mcp.server
4. Add environment variable ALTSPORTSDATA_API_KEY

Option C: SSE/HTTP (Remote)

Run the server with HTTP transport:

ALTSPORTSDATA_API_KEY=your_key altsportsdata-mcp --sse --port 8080

Then in .cursor/mcp.json:

{
  "mcpServers": {
    "altsportsdata": {
      "url": "http://localhost:8080/mcp"
    }
  }
}

This also works for any MCP client that supports HTTP/SSE transport (Windsurf, Continue, etc.).

Connect to OpenClaw

Add to your OpenClaw config (openclaw config edit):

mcp:
  servers:
    altsportsdata:
      command: uv
      args:
        - run
        - --directory
        - /path/to/altsportsdata-mcp
        - python
        - -m
        - altsportsdata_mcp.server
      env:
        ALTSPORTSDATA_API_KEY: your_api_key
