About this agent

Slack's official hosted server, generally available since February 2026. Agents can search messages, files, users and channels, send or schedule messages, and read or edit canvases and lists, all within the user's permissions. It uses OAuth through a registered Slack app rather than dynamic client registration. It supersedes the old reference Slack server, which has been archived.
