What is the PubMed MCP Server?
Connect your AI agent to the National Library of Medicine's PubMed database — the undisputed gold standard for biomedical and life sciences literature worldwide.
What you can do
- Literature Search — Find research articles by keyword, disease name, gene symbol, drug, or any biomedical topic across 37M+ indexed articles using powerful boolean operators (AND, OR, NOT)
- Full Article Details — Retrieve comprehensive metadata including complete abstracts, all contributing authors, publishing journal, DOI, publication types, and MeSH descriptors for any article by PMID
- Citation Tracking — Discover which subsequent papers cite a specific article to trace the impact chain and follow the evolution of a research topic over time
How it works
- Subscribe to this server
- Start searching PubMed from Claude, Cursor, or any MCP-compatible client — no API key required
Who is this for?
- Healthcare Professionals — quickly locate clinical evidence, systematic reviews, and treatment guidelines without navigating the PubMed web interface
- Biomedical Researchers — run targeted literature searches and citation analyses directly from their AI coding assistant
- Science Writers & Journalists — find primary sources and peer-reviewed evidence for accurate scientific reporting
Built-in capabilities (3)
Get full details of a PubMed article by its PMID
Useful for tracing the impact of a paper and finding follow-up research. Find articles that cite a specific PubMed paper
Returns titles, authors, journals, abstracts, DOIs, and MeSH terms. Supports boolean operators: AND, OR, NOT. Search PubMed for biomedical and life sciences research articles

Frequently asked questions
Do I need an API key or any registration to use PubMed?
No. PubMed E-utilities are freely accessible to everyone without registration. An optional API key (available at ncbi.nlm.nih.gov) increases your rate limit from 3 to 10 requests per second, but is not required for standard usage.
What types of searches are supported and how can I refine my results?
You can search by keyword, disease name, gene symbol, drug name, author surname, or journal title. Boolean operators (AND, OR, NOT) and field tags like [Title], [Author], and [MeSH Terms] work natively. Example: 'CRISPR AND cancer NOT review' targets original research on CRISPR in oncology.
Can I access full-text articles through this server?
This server returns complete abstracts and metadata for all indexed articles. Full-text access depends on publisher open access policies — articles from PubMed Central (PMC) are freely available. The DOI link provided with each result allows direct navigation to the publisher's page.
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.
