Free tournament tools

Use NextArena in any AI assistant

NextArena’s tournament generators are available as an MCP server. Connect it to Claude, ChatGPT, Cursor or another MCP client, then describe your players, courts and format. The draws come from the same generators as this website.

Streamable HTTP. No account, login or API key. The tools only calculate draws; they do not change anything.

Connect your assistant

Claude

  1. In Claude, open Settings, then Connectors.
  2. Choose Add custom connector. Name it NextArena and paste the server URL. Leave authentication empty.
  3. Start a new chat and turn on NextArena in the tools menu.

Custom connectors depend on your Claude plan and organisation settings.

Claude Code

Run this in your terminal:

claude mcp add --transport http nextarena https://www.nextarena.co/api/mcp

Cursor

Add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "nextarena": {
      "url": "https://www.nextarena.co/api/mcp"
    }
  }
}

VS Code

Add this to .vscode/mcp.json in your workspace:

{
  "servers": {
    "nextarena": {
      "type": "http",
      "url": "https://www.nextarena.co/api/mcp"
    }
  }
}

Other MCP clients

Add a remote server with the Streamable HTTP transport and the server URL above. No headers are needed.

Try asking

“Make a padel Americano for 16 players on 4 courts. 20-minute matches, starting at 9am.”

“Run a Mexicano for 10 players on 2 courts. Rank by average points per match.”

The assistant asks for the sport and format first. A Mexicano starts with round 1; each later round needs the scores of the round before it.

The tools

get_supported_tournament_options
Lists the sports and formats, so the assistant asks before it makes a draw.
generate_americano
Padel Americano: rotating partners, varied opponents and fair rests, planned before play.
generate_mexicano_round
Padel Mexicano: makes each round from the scores of the rounds before it.
calculate_mexicano_standings
Padel Mexicano: the individual table from the scores so far.
generate_round_robin
Pickleball round robin: singles, fixed doubles teams or rotating doubles.
generate_bracket
Pickleball knockout: seeded or random single-elimination brackets.

Every tool is read-only. Up to 64 entrants, 16 courts and 30 rounds per draw.

Your draw and scores

Tool inputs are sent to NextArena to calculate your draw, then returned to your conversation. They are not saved as a NextArena event. Keep the returned Mexicano state and scores in the same chat to continue. Use numbered players if you prefer not to share names. Hosting services may keep operational logs. Do not send contact details or other sensitive information.

To save an event, take registrations or publish live scores, use NextArena tournament software. You can also use the website generators without an assistant.
