Query Scholarly Metadata from DataCite

An MCP server that gives an AI assistant access to DataCite's GraphQL API, which holds rich metadata on scholarly works: DOIs, datasets, software, and publications, plus their relationships to researchers, funding bodies, and organizations within the PID Graph, the Persistent Identifier Graph. Rather than a generic web search, this queries structured metadata directly from DataCite's own registry.

Use it when a question needs grounded, structured scholarly metadata - finding recent datasets on a topic, publications tied to a specific funder like the European Research Council, or exploring how a research output relates to its authors and funding organizations. It is scoped to what DataCite's GraphQL API covers: DOI-registered scholarly works and their PID Graph relationships, not general academic search across all publishers or a full-text search engine. The server runs on Cloudflare Workers and enforces MCP transport security by validating the Origin header, so isolated or non-browser clients may need to explicitly include null in MCP_ALLOWED_ORIGINS to be authorized.

Core capability is querying the DataCite GraphQL API for scholarly work metadata and PID Graph relationships between research outputs, researchers, funding bodies, and organizations. A legacy Server-Sent Events transport is available at /sse alongside the primary MCP endpoint, and the server is compatible with Cloudflare AI Playground for testing.

Via mcp-remote against the hosted server:

npx mcp-remote https://datacite-mcp-server.quentincody.workers.dev/mcp

Configure Claude Desktop:

{
  "mcpServers": {
    "datacite": {
      "command": "npx",
      "args": [
        "mcp-remote",
        "https://datacite-mcp-server.quentincody.workers.dev/mcp"
      ]
    }
  }
}

To run from source or self-host on Cloudflare Workers:

git clone https://github.com/yourusername/datacite-mcp-server.git
cd datacite-mcp-server
npm install
npm run dev

then npx wrangler deploy to publish. Licensed under MIT with an academic citation requirement for research use; commercial use follows standard MIT terms.

Researchers, librarians, and developers who need to query scholarly metadata and relationships, such as datasets, publications, and funders, directly from DataCite's PID Graph instead of a general search engine.
