Slack MCP Server
About This Server
A popular community Slack MCP server that lets AI agents read and write Slack workspaces — send/receive messages, pull channel and DM history, search conversations, with stdio/SSE transports and proxy support, notably able to connect without admin-approved app permissions.

Does Slack MCP need an admin-approved app?
That is its selling point: it can connect using browser session tokens and similar, without installing an admin-approved Slack app in the workspace or requesting many scopes, keeping the barrier low for individuals. That said, follow your organization's Slack usage policy and security rules.
Is it an official product? Is it stable?
It is a community-maintained open-source project (not by Slack), written in Go, with active stars and iteration, and one of the most full-featured Slack MCPs today. For production use, evaluate the permission scope and compliance requirements and pin a version.
What typical tasks can Slack MCP do?
It lets an agent summarize unread channels, search past discussions for conclusions, turn a thread into to-dos, or send/reply messages on command. Combined with calendar and task tools, you can build a "read chat → distill action items → act across tools" automation.
