PubMedSAFE
A MCP server for PubMed data
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
A MCP server that allows to search and fetch articles from PubMed.
PubMed is a database of over 35 million citations for biomedical literature from MEDLINE, life science journals, and online books.
This MCP server relies on the pubmedclient Python package to perform the search and fetch operations.
Usage
Add the following to your claude_desktop_config.json file:
{
"mcpServers": {
"pubmedmcp": {
"command": "uvx",
"args": ["pubmedmcp@latest"],
"env": {
"UV_PRERELEASE": "allow",
"UV_PYTHON": "3.12"
}
}
}
}Make sure uv is installed on your system and 'uvx' is available in your PATH (claude PATH sometimes is not the same as your system PATH). You can add a PATH key in your claude_desktop_config.json file to make sure uv is available in claude PATH.

Questions
What is the PubMed MCP server?
A MCP server for PubMed data
What tools does PubMed expose?
1 in total: 1 read-only, 0 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is PubMed safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does PubMed need?
No credential environment variables were found in its source, so it appears to need none.
How current is this page?
The grade is for one exact copy of the source (30207689958c), read on 2026-10-07. The repository is watched and re-audited when it changes.
