Pulls current model IDs, pricing, and specs for 107 models across 19 AI providers into any MCP client. Exposes six tools: get_model_info for full specs, check_model_status to verify if a model is current or deprecated, compare_models for side-by-side analysis, recommend_model for task-based suggestions, list_models with filters for provider and capability, and search_models for free-text queries. Built in Go with sub-millisecond responses and zero external API calls. The registry updates daily and catches common mistakes like using gpt-4o (deprecated) instead of gpt-5 or outdated Claude model IDs. Useful when writing API integration code, comparing costs across providers, or preventing your agent from hallucinating model names that no longer exist.
