Trello

No. Atlassian states Trello MCP works with all Trello plans, and lists a Trello account on any plan as the only account-side prerequisite. One capability is gated: creating focus time in Planner requires Trello Premium or Enterprise. Reading calendar events from a connected Google or Outlook calendar in Planner is available more broadly.

No. Atlassian states Trello MCP does not support destructive delete operations, and that an assistant can archive cards and lists but cannot permanently delete them. That matters because deletion in Trello proper is permanent and unrecoverable, and requires archiving first. Archiving is fully reversible from the board menu.

Yes. The server's own OAuth descriptor advertises twelve scopes that pair read and write separately for boards, organizations, Inbox and Planner, and member reads carry no write counterpart at all. Atlassian's consent screen asks you to review and approve permissions individually, so declining every write scope is a supported outcome.

Because those two permissions operate at the account level, not the workspace level. Atlassian explains they are tied to your organization's management controls, so selecting a workspace your organization does not own can disable them. Board and card read and write permissions for that workspace remain available, and Inbox and Planner can sometimes connect with no workspace at all.

One. Atlassian states each Trello MCP connection supports a single workspace at launch, chosen on the consent screen, with multi-workspace support planned for a future release. Your assistant can only reach the workspace you explicitly authorise. To work across two workspaces today you must disconnect and reconnect against the other one.

Yes, through Atlassian Administration rather than through Trello. Atlassian documents the path as Rovo, then Rovo MCP server, then Permissions, where an admin edits the Read or Write row and unchecks read_trello or write_trello. Admins can also allow or block specific MCP client domains on the Domains tab. Changes take effect immediately.

Yes, through Trello's normal notification rules, because it acts as you. Trello notifies people when someone else adds them to a card or board, mentions them, or changes a card they watch. Trello also states you receive no notifications for your own actions, so an agent acting as you produces alerts you will not see yourself.

Yes. Atlassian states that focus time events you create in Trello appear in your connected calendar, and Planner supports Google Calendar and Microsoft Outlook Calendar accounts. Card links stay inside Planner and are not written to the calendar. So a Planner write is the one Trello MCP action that leaves Trello entirely.
