What is the MCP Server?

PubTator3 API compatible with the MCP agent protocol

The short version

This project provides an async Python server for interacting with the PubTator3 API. It exposes multiple biomedical text-mining tools compatible with the MCP agent protocol, supporting tasks such as entity lookup, biomedical literature search, and text extraction from PubMed/PMC articles.

  • Entity Autocomplete: — Find biomedical entities (genes, diseases, chemicals, variants) using free-text queries
  • Literature Search: — Search the PubTator3 database using keywords, entity IDs, or entity relations
  • Article Retrieval: — Download and extract text from PubMed/PMC articles in multiple formats
  • Find Related Entities: — Query for entities related to a given identifier via customizable relation and type filters
  • Async and Fast: — Uses aiohttp for non-blocking HTTP requests; designed for integration into broader MCP environments
