Org-owned product repo, then verdict, then stars

✓SAFE B

Pick this one because it is the only SAFE server of the 3.

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.

The URL slugs (calculator, calculator-5, calculator-3) are fixed IDs; any number in them says nothing about quality. Titles always carry the org/repo. Audited 7 Oct 2026.

How to tell them apart

Check the package

Install by the full package name (mcp-server-calculator on PyPI for our pick), not by searching “Calculator”.

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.
