What the publisher says
From the Pubcrawl repository's README, as published. We do not edit it. Read it on GitHub
An MCP server that gives AI assistants access to PubMed, Europe PMC, FDA & UK drug labelling, and ClinicalTrials.gov.
A peer-reviewed pub crawl through the literature — the label — and the trial.

✨ What is PubCrawl?
PubCrawl connects your AI assistant (Claude Desktop, Cursor, or any MCP-compatible client) directly to the primary sources clinicians and researchers actually use — so you can ask a question in plain English and get an answer grounded in PubMed, Europe PMC, FDA/UK drug labelling, and ClinicalTrials.gov, with real PMIDs, NCT IDs, and DOIs you can verify.
Every tool is a thin, deterministic wrapper over an official API. Nothing is invented; every result cites its source.
The thing no other MCP server does
Ask "compare US and UK labelling for semaglutide" and PubCrawl pulls both live labels and maps equivalent sections — US Indications and Usage ↔ UK 4.1 Therapeutic indications, and so on — so the differences are visible instead of assumed:
A cardiovascular claim that is on-label in the US promotes an unlicensed indication in the UK. If you write, review, or check medical copy for both markets, that gap is the whole job — and compare_labels is the only MCP tool that surfaces it.
Everything else
Shortened. The full README is on GitHub.
Nothing above is checked by us. What we check is on the safety report.
Install directly
Runs npx -y @pharmatools/pubcrawl on your machine. Read the scan report first; the gateway never runs local packages.
