Scorezilla MCP Server

scorezilla-mcp

Official Model Context Protocol (MCP) server for Scorezilla — the easiest way to add a leaderboard to your game. Connect this server to your AI coding assistant (Claude Code, Cursor, Continue.dev, …) and ship a working leaderboard without leaving your editor.

What you can ask the AI to do

• "Add a leaderboard to my game" → it bootstraps a game + board and pastes ready-to-run TypeScript SDK code into your project
• "What did my last test score rank?" → it reads your live leaderboard
• "List my games" / "show me the boards on X" → it inspects what you already have

Eleven tools total — five read-only, and six that write: four that create resources (bootstrap_leaderboard, create_game, create_board, mint_key) plus two that update config (update_board_config — score bounds + retention, e.g. an anti-cheat maxScore; update_game_config — the browser-submit origin allowlist).

Install + configure

Access — open to every Scorezilla account. Sign up free at dashboard.scorezilla.dev, create a token, and go. Creating games and boards counts toward your plan's limits (Free: 2 games × 3 boards each); when you hit one, the tool error includes a direct upgrade link. See pricing.

1. Get a token

Sign in at dashboard.scorezilla.dev, open MCP tokens, click Create token. Copy the mcp_live_* value once — it's not shown again.

2. Add the server to your AI coding assistant

Claude Code — edit ~/.claude/settings.json:

{
  "mcpServers": {
    "scorezilla": {
      "command": "npx",
      "args": ["-y", "@scorezilla/mcp"],
      "env": {
        "SCOREZILLA_TOKEN": "mcp_live_…"
      }
    }
  }
}

🔒 Keep ~/.claude/settings.json private. The token is stored in plaintext in that file. Make sure it's not committed to git (it's usually in your .gitignore), not synced to a public dotfiles repo, and not backed up to a shared location. On macOS/Linux: chmod 600 ~/.claude/settings.json so only your user can read it. If a token leaks, revoke it at dashboard.scorezilla.dev/account/tokens.

Cursor — open Settings → Features → MCP → Add new MCP server, then use the same command + args + env shape.

Anything else MCP-compatible — point your client at npx -y @scorezilla/mcp with SCOREZILLA_TOKEN set in the environment.

3. Ask away

In Claude Code or Cursor: "Add a Scorezilla leaderboard to this game."

Tools

Flags

scorezilla-mcp [--read-only] [--base-url=<url>] [--version] [--help]

• --read-only — refuse to register the write tools (bootstrap_leaderboard, create_game, create_board, mint_key, update_board_config, update_game_config). Use this on shared/CI configs to guarantee the AI can't create or change resources.
• --base-url=<url> — override the API origin. Defaults to https://api.scorezilla.dev. Useful for self-hosted or staging environments.

Env vars

• SCOREZILLA_TOKEN — required. Bearer token issued at dashboard.scorezilla.dev/account/tokens.
• SCOREZILLA_BASE_URL — same as --base-url, but via env. CLI flag wins if both are set.
• SCOREZILLA_BETA_TOKEN — no longer needed; the MCP is open to every account. Kept for compatibility (sent as X-MCP-Beta when set).

Tokens: how they work

• Tokens are scoped to the developer who issued them and see every game associated with their account.
• The MCP server never returns the secret-key plaintext for a game — for that, copy from the dashboard.
• Revoke a token any time at dashboard.scorezilla.dev/account/tokens. Revocations propagate within a few seconds.
• Tokens are bearer credentials: anyone with the value can call the API on your behalf. Don't commit them to source; don't paste them into shared chats. Keep them in env blocks, password managers, or secret stores.

Runtime requirements

• Node ≥ 20
• A network path to https://api.scorezilla.dev

Releasing

Releases are CI-driven and require an approval click in the npm-publish GitHub Environment. The full flow:

1. Author a changeset locally: pnpm changeset — describes what changed and the bump type. Commit the file under .changeset/.
2. Merge to main. .github/workflows/release.yml runs and opens a "chore(release): version @scorezilla/mcp" PR that bumps package.json, syncs server.json (the MCP Registry manifest) via scripts/sync-server-json-version.mjs, and updates CHANGELOG.md.
3. Merge the version PR. The same workflow then publishes:
   • npm tarball with --provenance (verifiable build attestation via GH OIDC + sigstore), plus a @scorezilla/mcp@<version> git tag and GitHub release (notes from CHANGELOG.md)
   • Post-publish smoke test that installs the published tarball and runs the binary
   • MCP Registry record via mcp-publisher login github-oidc → mcp-publisher publish, only after the smoke test passes; it waits for npm to serve the version and retries while the Registry can't see it yet
4. Pre-flight guards that run before publish: typecheck, test, build, bin smoke (node dist/index.js --version), and release:check (asserts package.json and server.json versions agree).

Manual publishes from a developer terminal still work (bash scripts/publish.sh) but aren't the path CI takes — they skip provenance and approval gates. Use only for one-off recovery.
