npm vs PyPI: Security advisories reveal stark differences in dependency risks

By PulseAugur Editorial · [1 sources] ·

A comparison of security advisories for Node Package Manager (npm) and Python Package Index (PyPI) servers reveals significant differences in their dependency security landscapes. As of October 2026, PyPI servers showed a much higher percentage (92.5%) with no known critical or high advisories compared to npm packages (50.4%). However, for npm, most advisories were categorized as 'high,' while PyPI had more 'critical' advisories than 'high' ones. The analysis cautions that a published advisory does not automatically mean a server is exploitable, and the figures are snapshots in time, influenced by tooling and ecosystem habits. AI

    npm vs PyPI MCP servers: dependency advisories side by side

    <p>If you pick MCP servers by language, there is one number worth looking at before you commit. I looked at the most severe published advisory anywhere in the resolved dependency tree of each server's listed version, once for npm packages and once for PyPI packages.</p> <p>The tw…
