Is Slack well covered on Skillselion?
Slack has healthy, genuinely dedicated depth beyond the multi-app connectors - pulsemcp and waystation-ai both ship focused, well-described Slack servers, and jtalk22's self-host/managed-cloud variant (29 stars) adds real deployment-model choice. The fastslack author-substring trap is a good reminder that this matcher needs to check the token as a whole word, not merely "appears somewhere in the row."

Common questions
How are these Slack MCP servers ranked?
By GitHub stars across the 24 Slack MCP servers that name Slack in their own name or description - none of these report installs yet. Data from GitHub.
How do I add a Slack MCP server to Claude Code?
Open the server's listing from the table above and copy its install command or JSON config. In Claude Code, register it with `claude mcp add <name> -- <command>` (or paste the config into your MCP settings). The same servers work in Cursor, Codex and any MCP-compatible agent.
What counts as a Slack MCP server on this list?
A tool counts here if its own name or description names Slack directly - not merely an author handle or an unrelated mention - and it is registered as an MCP-type listing in the Skillselion catalog. That bar currently matches 24 servers.
Is Skillselion affiliated with Slack?
No. Skillselion is an independent directory, not affiliated with Slack. Rankings come from public GitHub adoption signals, not sponsorship or partnership.
