Zoteus
Connects Claude to your Zotero library through both the Web API v3 and the desktop app's local API, giving you read and write access without leaving the conversation. You can search your own papers with hybrid semantic search, add items by DOI or arXiv ID, format bibliographies in any CSL style, and pull full text with page numbers. The write operations are gated and reversible by default. It auto-detects a running Zotero instance for fast local reads and falls back to cloud for sync and groups. One command install via npx, optional API key for writes. This is the one if you want to cite your own collection instead of hallucinating references or searching the open web.
