DataCite MCP Server

by alexwade

DataCite MCP Server

A Model Context Protocol (MCP) server that wraps the DataCite REST API, giving Claude and other MCP clients read-only access to DataCite's index of 125M+ research DOIs. No API key is required. The server runs as a local stdio process and communicates with Claude Desktop via the MCP protocol, enabling natural-language queries against the full DataCite catalogue: searching by keyword, person, funder, or repository; retrieving full metadata records; and exploring relationships between research outputs.

Claude Desktop Configuration

Add the following to your claude_desktop_config.json (found at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "datacite": {
      "command": "node",
      "args": ["/Users/[user_name]/Claude/projects/datacite/dist/index.js"]
    }
  }
}

Build Instructions

cd /Users/[user_name]/Claude/projects/datacite
npm install
npm run build

To inspect the server interactively:

npm run inspector

Available Tools

Tool

Description

search_dois

Full-text search across DataCite's 125M+ DOI index with filters for resource type, funder, year, repository, and more. Supports cursor-based pagination.

get_doi

Retrieve complete metadata for a single DOI. Accepts any common DOI format (bare, URL, doi: prefix). Optionally includes the raw DataCite Schema XML.

format_citation

Format a DOI as a formatted citation string. Supports APA, MLA, Chicago, Harvard, IEEE, Vancouver, BibTeX, and CSL JSON.

get_doi_metrics

Retrieve view, download, and citation counts for a DOI. Optionally include time-series arrays.

get_related_works

Explore the relationship graph for a DOI — citations, references, versions, and parts.

search_by_person

Find all DOIs associated with a researcher by ORCID iD or name.

list_repositories

Browse DataCite member repositories (clients) with optional search and filtering.

get_doi_schema_xml

Fetch the raw DataCite Metadata Schema XML for a DOI (base64-decoded).

Available Prompts

Prompts are pre-built workflows invocable from Claude Desktop's prompt menu (⌘K → "Use a prompt").

Prompt

Arguments

Description

find-top-works-by-topic

resource_type (required), topic (required)

Find the top 10 most relevant DataCite records for a resource type and subject area. Returns a ranked table with repository/year observations and a suggested follow-up.

repository-summary

repository_name (required)

Full metadata quality and activity report for a repository. Pass a common name like "Zenodo" or "Dryad" — the prompt resolves it to a DataCite client_id automatically.

researcher-profile

identifier (required)

Researcher profile from DataCite records. Pass an ORCID iD (0000-0001-8135-3489) for exact matching, or a name ("Jane Smith") for fuzzy search with disambiguation.
