Our pick
Org-owned product repo, then verdict, then stars
w31r4/codex-mcp-go · npm @zenfun510/codex-mcp-go 0.2.1
Pick this one because it is the only SAFE server of the 2 and it has the most stars (52).
The rule: a repository owned by an organisation account that carries the product's name comes first, then the better verdict, then the more stars. None of these servers meets the first test, so the verdict and stars decided it. It is a ranking of what the records show, not an endorsement by a vendor.

How to tell them apart
Check the package
Install by the full package name (@zenfun510/codex-mcp-go on npm for our pick), not by searching “Codex”.
Check the org
Every card shows org/repo. Our page for each server links to the exact repository we read.
Check the verdict
A good name says nothing about the code. Open a BLOCK page to see what we found.
