Overview
Trello is a hosted visual work management tool built around boards, lists, and cards. Teams use it to organize projects and workflows, while built-in automation, templates, integrations, Inbox, and Planner support task capture and scheduling. It is used across product, engineering, marketing, design, and remote-team workflows. Trello's official MCP server lets compatible AI assistants search and manage boards, lists, cards, checklists, and Inbox items, and can connect Planner actions to calendars where supported. Trello is proprietary Atlassian software rather than an open-source application. The official MCP repository is listed as related tooling.
