CoD Stats Tracker

What it does

CoD Stats Tracker is a full-stack MCP App that brings Call of Duty ranked performance data into ChatGPT. Players log ranked sessions, track SR (Skill Rating) movement match-by-match, and review win/loss breakdowns — all via a ChatGPT App connector that renders interactive UI widgets inside the conversation.

The product has two surfaces: a signed-in web dashboard at /dashboard for session management and match logging, and a ChatGPT App MCP connector that exposes read-only stats and account actions through a set of authenticated tools with interactive widget UIs for session summaries, match history, rank ladders, and settings.

Key features

• Ranked session tracking — create active sessions per title/season, log matches with SR delta, view cumulative SR timeline
• Match logging flows — Comprehensive (full detail) or Basic (fast everyday path), preference persisted per user
• Interactive ChatGPT widgets — session.html, matches.html, rank.html, settings.html rendered as sandboxed iframes in ChatGPT conversation
• OAuth-secured tools — full OAuth 2.0 flow (authorize/token/revoke endpoints) with per-scope access control; stats protected behind stats.read scope
• Optional billing — Stripe-gated checkout surface for plan-aware features
• Automated preflight checks — bun run verify:chatgpt-app validates MCP, OAuth, and widget metadata before submission

Installation

Deploy the Next.js app (Vercel, Fly.io, etc.) with Convex backend, Clerk auth, and required env vars.

Claude Desktop — not the primary target; app is ChatGPT-first but MCP endpoint is standard:

{
  "mcpServers": {
    "cod-stats": {
      "url": "https://<your-domain>/mcp"
    }
  }
}

ChatGPT:

1. Enable Developer Mode in ChatGPT
2. Add connector at Settings → Connectors with URL https://<your-domain>/mcp
3. Authenticate via OAuth when prompted
4. Ask: "Open my CoD stats dashboard"

Supported hosts

ChatGPT (primary). Standard MCP endpoint at /mcp works with any MCP-compatible client.
