The short version

As of November 2026, Slack runs a hosted MCP server at mcp.slack.com, generally available since February 17, 2026. It can search messages and files, read channels and threads, and send, schedule or draft messages, within your Slack permissions. Workspace admins approve which AI clients can use it, and Slack's guides list Claude, Claude Code, Cursor, Perplexity and ChatGPT. If all your conversations live in Slack, it is the official route. ConnectChats puts Slack next to WhatsApp, Telegram and your other chats, so one question covers all of them.
