What we love

✓Reference implementation maintained by the MCP project
✓Read-and-write coverage of core Slack workflows
✓Token-scoped permissions keep blast radius small

Where it falls short

−No support yet for Canvas, Lists, or Slack AI features
−Workspace admin must approve the app for OAuth flow
−Rate limits apply to your bot token — bulk reads are slow
