🔍 Enable AI assistants to search, access, and analyze PubMed articles through a simple MCP interface.

The PubMed MCP Server provides a bridge between AI assistants and PubMed's vast repository of biomedical literature through the Model Context Protocol (MCP). It allows AI models to search for scientific articles, access their metadata, and perform deep analysis in a programmatic way.

## 🔄 Europe PMC backend (v0.0.1)

This fork ships an additional `pubmed_mcp_server` package whose search backend is the
**Europe PMC REST API** (`https://www.ebi.ac.uk/europepmc/webservices/rest/search`) instead of
NCBI E-utilities.

### Why Europe PMC replaces NCBI

When the server runs inside a sandbox / cloud environment (e.g. the ROCK sandbox), NCBI
E-utilities frequently rate-limits or blocks the shared egress IP and returns an HTML error page.
The upstream code feeds that HTML into an XML parser, so the tool call fails with:

```text
Error executing tool search_pubmed_articles: mismatched tag: line 198, column 2
```

Europe PMC stays reachable from those environments, requires no API key, and covers PubMed
content (`source: MED`) plus preprints, patents and Agricola records — so results are functionally
equivalent to PubMed for most biomedical queries.

### What changed

- Replaced the NCBI `esearch` + `efetch` XML flow with the Europe PMC REST API (`format=json`,
  `resultType=core`).
- Parses the Europe PMC JSON shape, including `journalInfo.journal.title`, `authorList`
  (with `authorString` fallback), `pubYear`/`pubMonth`/`pubDay` and `abstractText`.
- Keeps `User-Agent` / `Accept` headers, connect/read timeouts `(10, 30)` and retry with…
