Nothing serious here today

Today is the operative word: we check Pubcrawl every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start: NCBI_API_KEY (NCBI API key for higher rate limits (10 req/s vs 3 req/s). Optional — get one free at https://www.ncbi.nlm.nih.gov/account/). The author declared them in the registry entry; get the values from the project itself.

Pubcrawl — questions

Answers built from our own checks of this server.

Why is there no uptime for Pubcrawl?

Pubcrawl runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @pharmatools/pubcrawl was installed 86 times last week.

How do I connect Pubcrawl?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls @pharmatools/pubcrawl straight from npm; nothing to host, nothing to sign up for.

How many people use Pubcrawl?

The npm package @pharmatools/pubcrawl was installed 86 times in the last week. Week over week that is +259%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Pubcrawl open source?

Yes — it is published under the MIT licence, written in TypeScript and 14 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
