Overview

AI-generated overview

Lets an assistant manage round-robin ladders and record match scores for small clubs, with players joining by QR poster.

What you can do
This remote MCP server covers round-robin ladders and match scores for small clubs. According to its description, players join by QR poster without needing an app or an account. No individual tools are listed in the manifest, so the exact operations available are not documented here.
When to use it
Worth considering if you run a small club ladder and want an assistant to help manage standings and record match results. It is less useful if you need documented, granular tooling, since no tools are listed.
Requirements
A remote streamable HTTP endpoint at the provider's host; nothing is installed locally. It requires an Authorization header carrying a Bearer API key. A free key is offered at signup with a monthly recorded-match limit and no card required.
Before you install
The Authorization header is a secret credential and must be handled carefully. The server records match data, so results written through it may be visible to club members. No tools are listed, so what the assistant can change is not fully documented before installing.

Installation

In SourceWeft

  1. Open Ladderboard — round-robin ladders and match scores for small clubs in the dashboard and add it to a workspace.
  2. Connect Authorization token credentials. They are stored privately and never shown on public pages.
  3. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.rowb.ladder%2Fboard/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
