Zotero

This connects Claude to both your local Zotero instance and the cloud REST API, so you can import papers from DOI lists, manage collections, and search your library without opening the GUI. It hits localhost:23119 when Zotero is running or falls back to api.zotero.org with your API key. The import flow is clever: it fetches BibTeX from doi.org, tries CrossRef if that fails, then POSTs to the connector endpoint. Useful when you have a dozen DOIs from a lit review and want them in Zotero immediately, or when you need to script collection management and tagging. The REST API coverage is thorough, including batch operations, group libraries, and attachment handling, though you'll need to mind version headers for updates.
