Trello

Connects Claude or Gemini directly to the Trello API through 48 tools that map to boards, lists, cards, checklists, attachments, webhooks, and comments. Built on the trellio async client library with stdio transport, so it runs as a local subprocess with no network exposure. Ships with three workflow prompts for sprint planning and standups, plus resource templates for loading board and card context. Auth is handled through an interactive browser flow that stores credentials locally. Reach for this when you want to manage Trello projects conversationally or automate board operations without switching to the web UI. The 970 passing BDD test steps suggest solid coverage of the Trello API surface area.
