MCP Servers for Communication and Messaging
Messaging servers are how an assistant reports back to people rather than just to you. They are also the group where scopes deserve the most attention, because a bot token that can post anywhere is a bot token that can post anywhere by mistake.
Slack is the common case and the site covers it twice, once for Cursor specifically and once with Claude Desktop config alongside it. Both walk the same app-creation flow but land on slightly different scope lists.
