Our pick

Org-owned product repo, then verdict, then stars

Slack

avimbu/slack-mcp-server · npm slack-model-context-protocol-server 0.0.1

✓SAFE B

Pick this one because it is published from the avimbu organisation account under the product's name and it is the only SAFE server of the 4.

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. It is a ranking of what the records show, not an endorsement by a vendor.

The URL slugs (slack, slack-2, slack-10, slack-18) are fixed IDs; any number in them says nothing about quality. Titles always carry the org/repo. Audited 9 Oct 2026.

How to tell them apart

Check the package

Install by the full package name (slack-model-context-protocol-server on npm for our pick), not by searching “Slack”.

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.
