Slack
Overview
Slack's official MCP plugin connects an agent to a Slack workspace via the remote server at mcp.slack.com. Search messages, files, users, and channels (public and private), send messages and threaded replies, retrieve channel histories, create and share canvases, and read user profiles. Workspace admin must approve MCP integration before use.

The three MCPs Boris Cherny — creator of Claude Code — keeps connected every day in 2026: Slack for search and posts, BigQuery for analytics queries, and Sentry for error logs. The smallest setup that covers messaging, data, and production debugging without inflating context.
Three MCPs that turn meetings, channels, and docs into a single searchable workspace: Zoom Workspace for AI Companion summaries, transcripts, and recordings (Zoom's official MCP, published April 8, 2026); Slack for what came up across channels (official slackapi plugin); and Notion as the source of truth (4,302 stars).
