Claude connectorCommunityGrounded scientific literature for AI assistants
Valency Bond — Ground any AI assistant in the live scientific literature. Bond connects Claude to a continuously updated corpus of papers and preprints from trusted sources including arXiv, bioRxiv, medRxiv, and PubMed, refreshed every few hours so new work is reachable within hours of publication. With 38+ tools spanning semantic and metadata search, researcher profiles, co-author mapping, forward and backward citation graphs, publication and keyword trend analysis, and clean JSON or CSV export, Bond powers a full research workflow from first search to final citation. Responses are token-efficient and structured, so grounding your model adds real, current sources without flooding its context window. Ask questions the way you always have, and get back grounded answers with verifiable citations attached. Free for researchers, academics, and non-profits.
