Baselight

Connects Claude to Baselight's catalog of 70,000+ structured datasets spanning finance, demographics, sports, and other domains. You get direct query access to verified, traceable data that grounds LLM responses in facts rather than training data. Useful when you need Claude to reason over current public data, cross-reference sources during research, or mix structured datasets into analysis workflows. The streamable HTTP transport means you can integrate it without running local infrastructure. Baselight positions itself as the antidote to hallucination by routing requests through curated tables instead of parametric memory, so responses come with source attribution baked in.
