Snake MCP

Nokia-style Snake as an MCP App, with SQLite high scores and a leaderboard.

Live URLs

Connect a client

{
  "mcpServers": {
    "snake": {
      "url": "https://alexmcroberts--28d29b367c8711f18ed61607ee4eb77e.web.val.run/mcp"
    }
  }
}

Or with Claude Code:

claude mcp add --transport http snake https://alexmcroberts--28d29b367c8711f18ed61607ee4eb77e.web.val.run/mcp

Then ask: play snake or show the leaderboard.

How it works

Rendering mermaid diagram...
  1. The host calls play_snake and renders the MCP App from ui://snake/mcp-app.html.
  2. Play with arrow keys or the on-screen D-pad.
  3. On crash, enter a name — the app calls submit_score.
  4. Scores live in this val's SQLite database.
