PubMed

You get a PubMed MCP Server that exposes PubMed and PubMed Central APIs through a suite of MCP tools. It lets you search, retrieve, and analyze biomedical literature directly from your MCP-enabled environment, with real-time access to 36+ million citations and structured metadata across articles, abstracts,MeSH terms, and full text when available.

How to use

You interact with the PubMed MCP Server through your MCP client by selecting the tools you need, such as searching articles, retrieving abstracts, or batch lookups. Start by configuring a local MCP server instance as shown in the installation steps, then issue requests for search, retrieval, or citation data. The server handles rate limiting automatically and returns structured data that includes metadata, abstracts, MeSH terms, DOIs, and full-text availability when PMC provides it.

How to install

Prerequisites you need to prepare before running the server:

• Node.js 16 or newer is required.

• Optional: An NCBI API key improves rate limits. You can obtain one from your NCBI account settings.

Install the MCP server locally (basic configuration)

{
  "mcpServers": {
    "pubmed-server": {
      "command": "node",
      "args": ["path/to/pubmed-server/build/index.js"],
      "autoApprove": [
        "search_articles",
        "get_article_details",
        "get_abstract",
        "validate_pmid"
      ]
    }
  }
}

Install the MCP server with an API key for higher rate limits

{
  "mcpServers": {
    "pubmed-server": {
      "command": "node",
      "args": ["path/to/pubmed-server/build/index.js"],
      "env": {
        "NCBI_API_KEY": "your_api_key_here",
        "NCBI_EMAIL": "your_email@example.com"
      },
      "autoApprove": [
        "search_articles",
        "get_article_details",
        "get_abstract",
        "validate_pmid",
        "search_by_author",
        "search_by_journal"
      ]
    }
  }
}

Additional setup notes

These configurations are designed to work with standard MCP tooling. If you need to run the server locally, ensure your environment has network access to PubMed and PubMed Central endpoints, and that your Node.js installation is available in your shell path.

Configuration and usage tips

• The server automatically throttles requests to comply with NCBI usage policies. Without an API key you are limited to a lower request rate; with a key you gain higher throughput.

• You can perform a range of searches including keyword, author, journal, MeSH terms, and advanced boolean queries. Look for results with associated metadata such as PMIDs, DOIs, and PMC IDs when full text is available.

Troubleshooting

Common issues include invalid PMIDs, rate limit warnings, or missing full text. Verify PMIDs are numeric strings, ensure your API key (if used) is valid, and consider batch lookups for efficiency.
