Cite Caddy MCP server

What it does

Cite Caddy is an MCP server that provides full read/write access to a Zotero library. It exposes 39 tools for searching, adding, updating, deleting, and organizing bibliographic items, collections, tags, and attachments. It is for developers building AI assistants that need to interact with and manage Zotero reference libraries.

• Search your Zotero library and retrieve item metadata, full text from attachments, or saved searches programmatically.
• Automatically add, update, tag, or organize bibliography items in Zotero based on AI-driven decisions or user input.
• Delete or move items between libraries and manage library-wide tags and trash, with support for idempotent operations to avoid duplicates on retry.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
