### Description (declared)

# mcp-refchecker

An MCP server that lets Claude verify academic citations in real time against [Semantic Scholar](https://www.semanticscholar.org/), [OpenAlex](https://openalex.org/), and [Crossref](https://www.crossref.org/) — catching hallucinated or incorrect references before they end up in your work.

Built on top of [academic-refchecker](https://github.com/markrussinovich/refchecker) (MIT).

## Tool

**`verify_citation`** — verifies that a cited paper exists and that its metadata (title, authors, year, venue) matches what was cited.

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `title` | string | yes | Title of the cited paper |
| `authors` | string[] | no | List of author names |
| `year` | integer | no | Publication year |
| `doi` | string | no | DOI (e.g. `10.1145/12345`) |
| `arxiv_id` | string | no | arXiv ID (e.g. `2301.00001`) |
| `url` | string | no | Direct URL to the paper |

Returns JSON:
```json
{
  "verified": true,
  "url": "https://...",
  "matched_paper": {
    "title": "...",
    "authors": [...],
    "year": 2023,
    "venue": "..."
  },
  "possible_match": null,
  "errors": null,
  "warnings": null,
  "info": null
}
```

### Result fields

- **`verified`** — `true` if the paper was found and all provided metadata (year, authors, venue) matches. `false` if there is a real metadata conflict or the paper could not be found.
- **`matched_paper`** — the authoritative metadata from the verification source.
- **`possible_match`** — a Crossref fallback match when the exact title was not found but a close variant was (see "Fuzzy fallback" below).
- **`errors`** — hard errors that block verification (wrong year, wrong authors, paper not found).
- **`warnings`** — soft warnings that don't block verification (arXiv v1 vs v2 differences, arXiv preprint vs published venue, incomplete input metadata).
- **`info`** — informational suggestions (e.g., "reference could include arXiv URL").
