Manage Trello boards and cards

Trello is a visual collaboration tool that helps you organize projects, tasks, and workflows using boards, lists, and cards.

With Trello in Sim, you can:

  • List boards and lists: View the boards you have access to and their associated lists.
  • List and search cards: Retrieve all cards on a board or filter by list to see their content and status.
  • Create cards: Add new cards to a Trello list, including descriptions, labels, and due dates.
  • Update and move cards: Edit card properties, move cards across lists, and set due dates or labels.
  • Get recent activity: Retrieve actions and activity history for boards and cards.
  • Comment on cards: Add comments to cards for collaboration and tracking.

Integrating Trello with Sim empowers your agents to manage your team’s tasks, boards, and projects programmatically. Automate project management workflows, keep task lists up-to-date, synchronize with other tools, or trigger intelligent workflows in response to Trello events—all through your AI agents.
