Overview

AI-generated overview

A read-only MCP server that gives an assistant the rules, roster constraints, FAQ and official links for the 27-0 NRL fantasy draft browser game.

What you can do
Retrieve the game rules, roster-building constraints and public entry points for 27-0 (get_game_rules). Retrieve the canonical list of official links, such as the website and support contact (get_official_links). Read site resources covering the rules, a short FAQ and canonical links. Use bundled prompts to summarize the game or plan a single play-through.
When to use it
Useful when someone asks an assistant about the 27-0 rugby league draft game and wants accurate rules, roster positions, game modes or official links rather than guesses. It is a small reference server, not a way to play the game.
Requirements
Runs as a local stdio process on the user's machine, started with Node.js (for example via the Smithery CLI or from source with pnpm). No API keys, accounts or environment variables are declared.
Before you install
Read-only and needs no credentials. The game data is site-curated fan content, not official NRL records, and the simulation is an entertainment mechanic rather than a prediction; the project states it is unaffiliated with the NRL or any club.

Installation

🎮 About 27-0

27-0 is a free browser game for NRL fans who want to build an all-time rugby league XIII and see whether it can survive a perfect season. The site turns an ordinary greatest-player debate into a constrained draft: each round spins an NRL club and era, then the player chooses one eligible legend for the open position. After thirteen picks, the lineup is run through a seeded 27-round season simulation. The goal is an undefeated 27-0 record and the highest available grade, not a prediction of a real NRL result.

Key Features

  • Fixed 13-player lineup — The roster follows the NRL jersey structure: fullback, two wings, two centres, five-eighth, halfback, two props, hooker, two second-rowers, and lock. A pick must fit the position currently open, so famous names alone cannot solve the draft.
  • Club-and-era spins — Every selection starts from a historical club and era pool. Players choose from the legends eligible for that spin instead of searching an unrestricted database.
  • 27-round simulation — A completed XIII is evaluated across 27 rounds, with regular-season and finals stages leading to a grand final. The simulation is deterministic for a given seed and roster, which makes shared runs reproducible.
  • Three draft experiences — Classic keeps player stats visible for number-based decisions. Daily uses the same thirteen spins for everyone, allows one attempt, and resets at midnight AEST. Footy IQ hides the stats so the draft relies on memory and rugby knowledge.
  • Leaderboards and share codes — Players can submit a result to the leaderboard and share a compact code that recreates the run. Leaderboard entries are user-submitted game results, not certified competitive records. The public pages include the play screen, daily challenge, leaderboard, and share routes.
  • Free and independent — The game runs in a browser without an account requirement for play. It is an independent fan project and is not affiliated with the NRL or any club. Player names, statistics, and ratings are site-curated game data used for commentary and parody, not official NRL records.

Use Cases

NRL fans can use Classic to compare the game's displayed player profiles, use Footy IQ to test historical knowledge, or return to Daily for a shared challenge. A group can play the same daily seed, post the resulting record, and open a share link to inspect the lineup and round-by-round story. The fixed positions create meaningful trade-offs between backs, forwards, spine roles, and the strength of each club-era pool.

Who Is It For

27-0 is for rugby league supporters who enjoy all-time debates, roster builders, daily games, and short competitive sessions. It is designed to be completed in a few minutes on desktop or mobile. The simulation is an entertainment mechanic: it should not be read as an official ranking of players, clubs, or likely real-world match outcomes.
