  "what": "The most widely used Slack MCP server, MIT-licensed and not affiliated with Slack. It supports bot and OAuth tokens plus a 'stealth mode' using browser session tokens that needs no app install or admin approval. It fetches channel and thread history, searches messages, adds reactions, marks read and posts.",
  "why": "The realistic way to give an agent Slack context when you are not a workspace admin and cannot get an app approved. Message posting is off by default, so read-only triage works safely out of the box.",
  "warn": "Stealth mode hands long-lived browser session cookies to a community binary and may breach your workspace policy. The MCP steering group's Slack reference server is archived, so every option here is community-maintained.",
