Compatible with every major AI agent and IDE
What is the PubMed Central MCP Server?
Connect your AI agent to PubMed Central (PMC), the world's premier digital archive of biomedical and life sciences journal literature. This server enables deep exploration of millions of open-access articles directly through natural conversation.
What you can do
- Advanced Search — Use
search_articlesto find PMCIDs matching complex queries, including authors, dates, and specific filters. - Full-Text Retrieval — Access complete article content in BioC XML or JSON formats using
get_bioc_articlefor deep analysis. - Citation Analysis — Track the scientific impact of research by finding articles that cite a specific PMID with
get_citing_articles. - Identifier Mapping — Seamlessly convert between PMCIDs, PMIDs, and DOIs using
convert_idsto ensure data consistency. - Metadata Harvesting — Retrieve document summaries, license information, and file locations for Open Access records via
get_article_summaryandget_oa_record.
How it works
- Subscribe to this server
- Provide your NCBI Tool Name and Email (and an optional API Key for higher rate limits)
- Start querying the global repository of medical knowledge from Claude, Cursor, or any MCP-compatible client
Who is this for?
- Researchers & Academics — Instantly find relevant literature and extract data from full-text papers without manual downloading.
- Healthcare Professionals — Quickly verify medical facts and access the latest clinical studies directly from your workspace.
- Data Scientists — Automate the collection of biomedical datasets and citation networks for large-scale analysis.

Frequently asked questions
How do I convert a DOI or PMID into a PMCID for full-text access?
Use the convert_ids tool. Provide a comma-separated list of identifiers, and the agent will return the mapped PMCID, which is required for many other PMC retrieval tools.
Can I retrieve the actual content of an article, not just the abstract?
Yes. If the article is in the Open Access subset, use get_bioc_article with the PMCID. You can specify 'json' or 'xml' format to get the full-text sections.
How can I find which papers have cited a specific study?
Use the get_citing_articles tool by providing the PubMed ID (PMID) of the study. It will return a list of PMC articles that reference that specific work.
How does Claude Desktop discover MCP tools?
When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.
What happens if the MCP server is temporarily unavailable?
Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.
Can I connect multiple MCP servers simultaneously?
Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.
Is there a limit on the number of tools per server?
Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.
Does Claude Desktop support Streamable HTTP transport?
Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
Server not appearing after restart
Ensure the JSON is valid (no trailing commas). Check the file path: ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\\Claude\\ (Windows).
Authentication error
Verify your Vinkius token is correct. Go to cloud.vinkius.com to regenerate it if needed.
Tools not showing in chat
Click the 🔌 icon at the bottom of the chat input. If it shows 0 tools, the server may still be connecting. wait a few seconds.
