Best MCP servers for Slack

We found 57 MCP servers for Slack in the catalog; these are the 15 that rank highest. The order comes from our rank, which weighs adoption, freshness, documentation and publisher identity. Nobody can pay for a place on this list. Connected Apps, Agent-Native Brain and Agent-Native Dispatch lead it. Keeploop, SandboxAPIs and Enhanciar — company brain are published by the company that makes them. Agent-Native Brain has the most GitHub stars here (7,507). 13 of the 15 had activity in the last 30 days. Remote servers need no local install; local ones run on your machine and can reach local files. Each entry lists why it made the list and links to its install page.
