About modelcontextprotocol/server-slack
The Slack MCP Server is an official reference implementation by Model Context Protocol that enables AI assistants like Claude to interact with Slack workspaces. It provides a comprehensive set of tools for channel management, messaging, thread replies, emoji reactions, channel history retrieval, thread replies viewing, user listing, and user profile details. The server requires setting up a custom Slack app with appropriate bot token scopes and installing it to a workspace.

Then add an entry in your claude_desktop_config.json using the npx command '@modelcontextprotocol/server-slack' with the token and team ID as environment variables.
