About Slack
Slack is turning its app platform into an AI-agent surface — MCP on both ends, richer Block Kit.
The developer-facing changelog is busy and coherent: a Slackbot MCP client and expanded Slack MCP server tools, new Block Kit blocks (data visualization, data table, alert/card/carousel), streaming API updates for AI assistants, and a steady drumbeat of CLI and SDK releases.
