### Description (declared)

# ryogena-pubmed-mcp

A small, focused **Model Context Protocol** server that exposes
[NCBI PubMed](https://pubmed.ncbi.nlm.nih.gov/) as MCP tools, so any
MCP-compatible client (Claude Desktop, Claude Code, custom agents) can
search the literature, fetch abstracts, walk the citation graph, and look
up an author's publications without leaving the chat.

No API key required. An optional `NCBI_API_KEY` raises the rate limit
from 3 → 10 requests/sec.

## Tools

| Tool | What it does |
|---|---|
| `search_pubmed(query, max_results, sort)` | Free-text or full-syntax PubMed query. Returns title, authors, journal, pubdate, DOI, PubMed URL. |
| `fetch_article(pmid)` | Full abstract for one PMID, with section labels preserved (Background / Methods / Results / Conclusions). |
| `find_related(pmid, max_results)` | NCBI's "related articles" neighbors — walk the citation graph from any paper. |
| `search_by_author(author, max_results, sort)` | Author publication list using the `[au]` field qualifier. |

All tools are read-only; PubMed itself is read-only.

## Install

```bash
pip install ryogena-pubmed-mcp
```

Or from source:

```bash
git clone https://github.com/KyleVick4/pubmed-mcp
cd pubmed-mcp
pip install -e .
```

## Configure in Claude Desktop

Edit your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "pubmed": {
      "command": "python",
      "args": ["-m", "pubmed_mcp"],
      "env": {
        "NCBI_API_KEY": "<optional>",
        "NCBI_EMAIL":   "<optional, recommended by NCBI>"
      }
    }
  }
}
```

Restart Claude Desktop. The `pubmed` server should show up in the MCP
panel with four tools.

## Configure in Claude Code

```bash
claude mcp add pubmed -- python -m pubmed_mcp
```

## Try it

Once wired up:

> *Find me the three most-cited papers on JAK2 V617F selectivity from 2023, then pull the abstract of the top hit.*

Claude will plan a `search_pubmed` → `fetch_article` chain and cite each
paper with its DOI and PubMed URL.
