Trello MCP

A hosted MCP server that lets AI assistants (ChatGPT, Claude, Codex, Claude Code, …) work in your Trello — with your own Trello authorization, on your own boards.

Connect

MCP endpoint (Streamable HTTP, OAuth 2.1):

https://mcp.tierbucket.com/mcp

ChatGPT (web, desktop, mobile): Settings → Connectors → Create (enable Developer mode if you don't see it) → paste the URL → Connect. You'll be sent to Trello to approve access.
Claude (claude.ai, desktop): Settings → Connectors → Add custom connector → paste the URL.
Claude Code: claude mcp add --transport http trello https://mcp.tierbucket.com/mcp
Codex CLI: codex mcp add trello --url https://mcp.tierbucket.com/mcp

What it can do

List/search boards, lists, and cards; create, edit, move, copy, comment, label, assign, checklist, attach; archive/restore. Nothing here deletes anything — "remove" always means archive, which is reversible in Trello.

Safety

Every write tool tells the assistant to get your explicit OK for that exact change first.
You can restrict a connection to specific boards during setup.
Revoke any time: Trello → Settings → Applications, and remove the connector in your assistant.
