### Description (declared)

A round-robin ladder and match-score board for small clubs. Players join by scanning one printed QR poster; standings are computed from entered results using a fixed published rule order (deterministic, same results always give the same table). This service is a plain REST API and an MCP server over Streamable HTTP - it is NOT an A2A JSON-RPC agent. Docs at the documentationUrl.
