About mcp-zotero
Xevos117/mcp-zotero
MCP server that exposes Zotero library operations as tools for Claude. Supports searching, browsing collections, adding items by DOI, importing PDFs with fulltext indexing, open access PDF discovery via Unpaywall, and injecting Zotero citation field codes into .docx documents.
Built on the Model Context Protocol, it uses a **self-documenting architecture** where workflow instructions and tool guidance are embedded in MCP's `instructions` field, enabling LLMs to discover full functionality without external docs. The server implements 15 tools across library operations, PDF management, and citation injection, with optional Claude skill support for sandboxed citation injection in Claude Desktop and Claude.ai Projects (which lack filesystem access). Configuration supports granular safety controls via `UNSAFE_OPERATIONS` to prevent accidental deletions, and integrates with Unpaywall for open-access PDF discovery.
