Connects your Claude environment to Slack workspaces, letting you read channels, post messages, and react to workspace activity without leaving your workflow. The key feature here is resource-based event subscriptions, so you can monitor channels or threads and get updates pushed to you rather than polling. Reach for this when you're building automation that needs to respond to Slack conversations, post status updates to team channels, or pull context from ongoing discussions into your development work. It uses Smithery's streamable HTTP transport, so you'll need to authenticate with your Slack workspace through their hosted service.
