Provides 50 tools covering boards, cards, lists, labels, checklists, attachments, members, custom fields, and search.
Quick Start
1. Get Trello API credentials
Trello no longer hands out API keys directly — each user must create their own Power-Up, then mint a token against that Power-Up's key.
- Visit https://trello.com/power-ups/admin and click New.
- Fill out the New Power-Up or Integration form:
- New Power-Up or Integration name:
Claude MCP. If you have multiple team members, each developer must create their own Power-Up so the API key is tied to their user — name it with your own name too, e.g.Trello MCP Steve. - Workspace: the workspace you want to interact with.
- Iframe connector URL:
https://localhost(required field, not actually used by this MCP server). - Email: your email.
- Support contact and Author: can be company-level or personal.
- New Power-Up or Integration name:
- Once the Power-Up is created, click API key in the sidebar, then Generate a new API key, then Generate API key in the confirmation modal. Trello displays both an API key and a Secret — save them somewhere safe.
- In a browser, visit:
Replacehttps://trello.com/1/authorize?expiration=never&scope=read,write,account&response_type=token&name={NAME}&key={APIKEY}{NAME}with the Power-Up name you chose and{APIKEY}with the key from the previous step. This is an auth prompt — confirm access and click Allow. Trello returns an API token; copy it. - Put the API key and token into your MCP client config (e.g.
.claude.json) — see the next section.
