What does slack do?

slack is a Claude Code plugin that connects Claude to Slack's own hosted MCP server, with an OAuth sign-in on first use, and adds nine skills and five commands. Through the server Claude can search messages, files, users and channels, send and schedule messages, read threads, add reactions and work with canvases. The commands are /slack:summarize-channel, /slack:find-discussions, /slack:draft-announcement, /slack:standup and /slack:channel-digest. The skills cover writing and searching messages, plus developer work: the Slack Web API, the Slack CLI, Block Kit layouts, and creating, testing and deploying Slack apps built with Bolt.

When should you use slack?

  • Catching up on a busy channel
