 # Scholar Search MCP
 
-A MCP server that integrates the [CORE API v3](https://api.core.ac.uk/docs/v3), [Semantic Scholar API](https://www.semanticscholar.org/product/api), and [arXiv API](https://info.arxiv.org/help/api/user-manual.html) so AI assistants (e.g. Claude, Cursor) can search and fetch academic paper metadata.

 ## Features
 
-- **Search papers** – Keyword search with **fallback chain**: tries **CORE API** first (no key required; set `CORE_API_KEY` for higher limits), then **Semantic Scholar**, then **arXiv**; optional year and venue filters (venue applies to Semantic Scholar only)
+- **Search papers** – Keyword search with parallel merge from **Semantic Scholar** and **arXiv**; optional year and venue filters (venue applies to Semantic Scholar only)
 - **Paper details** – Full metadata (title, authors, abstract, citations, etc.)
 - **Citations & references** – Papers that cite or are cited by a given paper
 - **Author info** – Author profile and paper list

-**Search fallback order:** When you call `search_papers`, the server tries sources in order and uses the first that succeeds:
+`search_papers` queries enabled sources in parallel and merges results by title:
 
-1. **CORE API** – Tried first; works without a key (subject to [rate limits](https://api.core.ac.uk/docs/v3#section/Rate-limits)). Set `CORE_API_KEY` for higher limits ([register](https://core.ac.uk/api-keys/register)).
-2. **Semantic Scholar** – Used if CORE fails; works without a key with lower limits. Set `SEMANTIC_SCHOLAR_API_KEY` for higher limits.
-3. **arXiv** – Used as last fallback; no key required.
