What this server can do
4 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.
check_model(model)- Check whether an AI model identifier is deprecated, retiring, or has silently changed (price, context window, capabilities). Accepts any spelling a provider or SDK uses, e.g. 'gpt-4-turbo', 'azure/gpt-4.1-mini', 'claude-opus-4-1-20250805'. Call this before writing a model identifier into code. Required: model.
check_models(models)- Check many model identifiers at once and report which are retired or scheduled for retirement. Use when auditing a codebase or config. Required: models.
recent_changes(limit, min_severity)- Recent breaking changes across AI model APIs: price moves, context-window cuts, removed capabilities, removals. One entry per real upstream change.
upcoming_retirements(within_days)- List models with an announced retirement date inside a horizon, soonest first.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
