EdgeFinder for Codex

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

Summary

EdgeFinder runs a remote MCP server so the OpenAI Codex CLI can query NFL, NBA, MLB, and Polymarket data directly.

Connect through the hosted MCP URL, or run the EdgeFinder CLI locally, then let Codex pull play-by-play, injuries, usage splits, and live odds and 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. Codex passes it to the MCP server as EDGEFINDER_API_KEY.

  2. Step 2

    Add EdgeFinder to your Codex config

    Edit ~/.codex/config.toml and add EdgeFinder as an MCP server. Restart Codex to pick up the new server.

    [mcp_servers.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 Codex can see the tools

    Start a new Codex session and ask what tools are 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 Codex MCP?

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

Does this work with the Codex CLI?

Yes. The EdgeFinder MCP server works with any MCP-compatible client, including the OpenAI Codex CLI.
