## Overview

UniArticles(亿文通) is a unified academic literature retrieval server implementing the Model Context Protocol (MCP). Integrates multiple scholarly databases (**Scopus**, **ArXiv**) and literature APIs (**PubMed**) into a single, standardized API for LLM agents (like Claude).
          
## Features

- **Unified Interface**: Single search structure for all sources.
- **Multi-Source Support**:
  - **Scopus**: Search, abstract details, journal/serial title lookup by ISSN, quota check.
  - **ScienceDirect**: Full-text article retrieval, article object (figures/tables/supplementary materials) metadata retrieval.
  - **ArXiv**: Search papers, list recent papers, read paper metadata by ID.
  - **PubMed (NCBI Entrez)**: Keyword search, batch summary lookup, related-article discovery, and PMC full-text/citation linkage — direct NCBI E-utilities calls (no third-party wrapper).
  - **General academic search (v3.0.0)**: OpenAlex, Crossref, Europe PMC, DOAJ, Zenodo, OpenAIRE, dblp, Semantic Scholar, and CORE keyword/DOI lookup across open scholarly catalogs.
  - **Specialized sources (v3.0.0)**: bioRxiv/medRxiv preprint browsing by date range.
- **Standardized Returns**: Consistent JSON structure (`ok`, `source`, `query`, `count`, `items`, `error`).
- **Secure Configuration**: API keys managed via environment variables.

## Supported Data Sources

UniArticles unifies the following **14 data sources** behind one consistent MCP interface, all returning the same normalized JSON shape. **13 are active by default**, providing **26 tools**; Semantic Scholar registers its 2 additional tools only when `SEMANTIC_SCHOLAR_API_KEY` is set, for a total of **28 tools**. Every source except arXiv is a direct call…
