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. |
Available Resources
| Resource URI | Description |
