certifi
A Python certificate bundle that provides the set of root certificates maintained by Mozilla, used for certificate verification during HTTPS requests.
Timeline (last 90 days)
Python's certifi package released version 2026.10.23 on October 23, 2026, removing two root certificates: eMudhra's emSign Root CA - C1 and emSign ECC Root CA - C3.
On the Python side, mcp-server-fetch uses httpx and relies on the certifi package for HTTPS validation; installing from PyPI resolves to the current version of certifi; in this release, the Dockerfile in the repository advanced the lock file to certifi 2026.10.23.
certifi is a standalone package in the Python ecosystem that bundles the Mozilla CA bundle, and libraries such as httpx and requests use it by default for TLS validation rather than the operating system certificate store.
The certifi version in the dev lockfile was bumped in v2.2.0.
certifi released version 2026.10.19, upgrading its built-in certificate list.
