Zotio
Research · Local stdio
Quality: 57/100 (Good) | Auth: API Key required
Verdict Summary: Choose Paperboy if you need specialized Research tools running via a local process. Choose Zotio if your workspace requires Research integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Paperboy when:
You need dedicated capabilities in the Research domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Free / Open Source).
You have access to required keys: ZOTERO_API_KEY, ZOTERO_LIBRARY_ID, SMTP_HOST, SMTP_PORT, SMTP_USERNAME, SMTP_PASSWORD, DROPBOX_ACCESS_TOKEN, DROPBOX_FOLDER.
Primary tools included: Search papers by arXiv ID, DOI, or title with fuzzy matching, Recommend related papers using Semantic Scholar citation graph, Queue papers in Zotero Reading Queue collection with duplicate protection.
Send research papers from Claude to a Kindle or Kobo, with Zotero as the source of truth. Searches arXiv and OpenAlex, recommends related work via the Semantic Scholar citation graph, queues papers in a Zotero collection, and delivers the PDFs by email or Dropbox. Receipts report file sizes and name anything that could not be sent.
Zotero MCP server (zotio-mcp) with a capability-tagged tool registry and preview-first, journaled writes (an agent can't silently mutate or delete your library). Reads work keyless against the local Zotero desktop API; writes route to the Web API. Ships an MCPB bundle for one-click Claude Desktop install.
