  "description": "The official Slack MCP server is Slack's first-party endpoint at mcp.slack.com/mcp. It exposes fifteen documented tools: search across messages, files, users, channels and emoji; send, draft and read messages and threads; create channels and DMs; add reactions; create, update and read canvases; look up user profiles and channel members; manage Lists; and a two-step file upload. Access is granted by OAuth and controlled through Slack's standard app-approval flow, so workspace admins decide which MCP clients may connect.",
