EdgeFinder for Claude

Give Claude access to live NFL, NBA, and MLB data, Polymarket odds, and player-level research through the EdgeFinder MCP server. Ask Claude any betting question and it can pull real data to answer.

Summary

EdgeFinder ships an MCP server so Claude Desktop and Claude Code can query NFL, NBA, MLB, and Polymarket data directly.

Instead of asking Claude to speculate, Claude can pull play-by-play, injuries, usage splits, and live odds through EdgeFinder, then answer with sourced context.

Use cases

  • - Player prop research with snap share, routes, targets, and red-zone usage.
  • - Injury impact checks using on/off samples and replacement patterns.
  • - Polymarket odds tracking and sportsbook cross-comparison.
  • - Parlay construction with per-leg probability reasoning.

Setup

  1. Step 1

    Get your EdgeFinder API key

    Generate an API key from your EdgeFinder integrations page. Claude passes it to the MCP server as EDGEFINDER_API_KEY.

  2. Step 2

    Add EdgeFinder to Claude

    Edit claude_desktop_config.json (Claude Desktop) or your Claude Code MCP config and add EdgeFinder as an MCP server. Restart Claude to pick up the new server.

    {
  "mcpServers": {
    "edgefinder": {
      "command": "npx",
      "args": ["-y", "@edgefinder/cli", "mcp"],
      "env": { "EDGEFINDER_API_KEY": "your-api-key-here" }
    }
  }
}

  3. Step 3

    Or use the remote HTTP URL

    For clients that only ask for an MCP server URL — like Grok or ChatGPT connectors — point them at the hosted EdgeFinder endpoint over HTTPS instead of running the CLI locally. Tool calls require an EdgeFinder API key, so prefer clients that let you send a request header.

    https://chat.edgefinder.io/api/mcp

Authorization: Bearer YOUR_EDGEFINDER_API_KEY

  4. Step 4

    No header support? Put the key in the URL

    If a connector UI only accepts a URL and gives you no way to set headers, pass your API key as a query parameter instead. The @edgefinder/cli package is for local MCP clients and does not host a public URL by itself.

    https://chat.edgefinder.io/api/mcp?api_key=YOUR_EDGEFINDER_API_KEY

  5. Step 5

    Verify Claude can see the tools

    In a new Claude chat, ask Claude what tools it has available. The EdgeFinder tools should appear.

Example queries

  • - Research Saquon Barkley rushing yards tonight against a top-5 run defense.
  • - How does LaMelo Ball's usage change when Brandon Miller is out?
  • - Build me a three-leg NBA parlay for tonight with Polymarket context.
  • - Compare Polymarket and sportsbook prices on the Giants spread right now.

FAQ

Do I need a paid EdgeFinder plan to use Claude MCP?

Yes. The MCP server requires an EdgeFinder subscription because the underlying data queries run against the paid API.

Does this work with Claude Code?

Yes. The EdgeFinder MCP server works with any MCP-compatible client including Claude Desktop and Claude Code.
