Overview

What is PubMed MCP Server?

The PubMed MCP Server is a Model Context Protocol (MCP) server that searches PubMed for article abstracts using BioPython's Entrez module and the FastMCP framework. It provides asynchronous search capabilities for researchers and developers who need to retrieve PubMed data through MCP‑compatible clients.

How to use PubMed MCP Server?

Clone the repository, install dependencies with uv add -r requirements.txt, set a valid email address in main.py (Entrez.email), then start the server with uv run main.py. Configure your MCP client with the path to uv and the server directory as specified in the config.json example. Use the search_pubmed tool with parameters query (default "endocarditis") and max_results (default 10).

Key features of PubMed MCP Server

  • Searches PubMed for articles by query term.
  • Retrieves abstracts of returned articles.
  • Asynchronous execution via asyncio.to_thread.
  • Built on the FastMCP framework.
  • Configurable maximum number of results.
  • Simple Python‑based setup with uv.

Use cases of PubMed MCP Server

  • Automating literature reviews by programmatically fetching PubMed abstracts.
  • Integrating PubMed search results into AI‑powered research assistants.
  • Building MCP‑enabled tools that require live biomedical literature data.
  • Batch‑retrieving abstracts for multiple search queries in parallel.

FAQ from PubMed MCP Server

What does the PubMed MCP Server do?

It allows MCP‑compatible clients to search PubMed and retrieve article abstracts asynchronously using a single tool (search_pubmed).

What are the required dependencies?

Python 3.8 or higher, the mcp[cli] package, and BioPython. Dependencies are managed via uv and a requirements.txt file.

How do I configure the Entrez email?

You must set a valid email address in main.py by assigning it to Entrez.email. This is required by NCBI’s Entrez usage policy.

What are the default search parameters?

The search tool uses a default query of "endocarditis" and a default max_results of 10. Both can be overridden when calling the tool.

Does the server have any data storage or authentication?

No. The server does not store data locally; it queries PubMed’s public API. No authentication is required beyond the valid email address.
