The MIT licence above covers this MCP server's source code only.

The data it fetches is licensed separately and is not sublicensed here.

- LMArena Elo is used under CC BY 4.0 from the official Hugging Face dataset
  (https://huggingface.co/datasets/lmarena-ai/leaderboard-dataset). Attribute
  LMArena when you republish a score. Each verdict document carries its own
  `licence` field saying so.
- Prices are rates a seller published on OpenRouter: the model's vendor or a
  reseller of it, named beside each price. This server does not grant a
  sublicence to those figures.
- Artificial Analysis index scores (intelligence, coding, agentic) never
  leave this server. Their free-tier terms are "Internal use only with
  attribution"; public redistribution needs a commercial licence we do not
  hold. See https://undominated.ai/methodology/.
