SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Zotero users often need to access external paper indexes and DOIs in a single workflow. This skill provides a unified CLI and MCP server interface to search, resolve DOIs, and retrieve full-text metadata across Zotero and external sources.

Core Features & Use Cases

  • Search Zotero library and collections and fetch item details.
  • Resolve DOIs to structured metadata and enrich results with OA PDF links when available.
  • Search external paper sources (arXiv, OpenAlex, Semantic Scholar, Europe PMC, DBLP, OpenReview, CORE, NASA ADS, PubMed) from a single command surface.
  • Expose a consistent interface for host agents or the CLI, supporting both cloud Zotero APIs and local Desktop API.

Quick Start

Ask paperbridge to search your Zotero library for a topic and return the top results.

FAQPage Schema
How do I search my Zotero library and external paper indexes at the same time?

You can search Zotero libraries and external paper indexes simultaneously from a single interface to retrieve, organize, and enrich paper data across cloud and local sources.

Can I resolve a DOI to structured metadata and find an OA PDF link?

Yes, DOI resolution retrieves structured metadata and enriches results with open access PDF links when available, applying to topic discovery and item validation workflows.

What external paper sources can I search through a unified Zotero workflow?

The unified command surface searches external paper sources including arXiv, OpenAlex, Semantic Scholar, Europe PMC, DBLP, OpenReview, CORE, NASA ADS, and PubMed.

Does this approach work with both cloud Zotero APIs and the local Desktop API?

Yes, the interface supports both cloud Zotero APIs and the local Desktop API, exposing a consistent interface for host agents or the CLI to perform read and search operations.

What is the best way to expose paper search and retrieval operations to a host agent?

The MCP and CLI interfaces expose consistent read, search, and DOI resolution operations with structured outputs, allowing host agents to retrieve full-text metadata across sources.

Do I need specific dependencies to perform full-text enrichment across Zotero and external sources?

No specific dependencies are required to perform full-text enrichment, as the skill uses MCP and CLI interfaces to validate items and retrieve metadata across cloud and external sources.
