20 Slack MCP servers. Which one to use.
Every Slack server we index, with whether its source is still reachable and whether we hold a screening verdict. 1 of 20 have a source repository that is no longer publicly reachable.
Scope: 20 servers, mostly mirrored from the MCP registry as of 2026-10-23. Most servers whose authors never published to the registry are absent, so treat this as close to the registry's view rather than a complete census.

“Repo unreachable” means the source returned a not-found from two vantage points, which can also happen when a repository is made private or moved - see source liveness. “Screened” is the advisory verdict on the listing text, never a safety clearance; the methodology spells out what each dimension does and does not test.
