Slack MCP Server vs Notion MCP Server

Where does your team's context live? The archived Slack reference server gives Claude access to channels and messages — conversational, ephemeral context. The Notion server reaches structured, long-lived documents. For agent workflows that summarize discussions, Slack fits; for ones that read and update specs, Notion — and Notion's active maintenance is a real advantage over an archived reference implementation.
