What is the DOAJ MCP Server?
Connect to the Directory of Open Access Journals (DOAJ) to explore millions of open access articles and journals. This server allows researchers to query metadata and publishers to manage their records through natural conversation.
What you can do
- Journal Discovery — Search the DOAJ database for journals using Elasticsearch syntax, including title, ISSN, and subject filters.
- Article Search — Find specific research papers and articles across thousands of open access publications.
- Metadata Retrieval — Fetch complete metadata for specific articles using their unique DOAJ IDs.
- Publisher Management — Create, update, or delete article records directly from your AI agent (requires API key).
- Bulk Operations — Upload high-volume batches of articles asynchronously for efficient catalog management.
- Journal Applications — Submit update requests for existing journals to keep directory information current.
How it works
- Subscribe to this server
- (Optional) Enter your DOAJ API Key for publisher features
- Start searching or managing academic content from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Researchers & Academics — quickly find open access sources and metadata without manual database browsing
- Publishers — manage article listings and journal updates directly from a command-line or AI interface
- Librarians & Data Scientists — automate the retrieval of scholarly metadata for analysis or cataloging

Frequently asked questions
Can I search for journals using specific fields like title or ISSN?
Yes! Use the search_journals tool with Elasticsearch query string syntax. For example, you can query bibjson.title:"Journal of Science" or bibjson.pissn:"1234-5678" to find exact matches.
How do I submit a batch of new articles at once?
You can use the bulk_create_articles tool. It allows you to submit a JSON array of article objects asynchronously. This is ideal for publishers managing high volumes of data.
Is it possible to request updates for an existing journal listing?
Yes, publishers can use the create_application tool to submit an update request for an existing journal by providing the updated metadata and referencing the current journal ID.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
