Connect Gmail to Trello
Automate Gmail and Trello with AI
Flag a Gmail message that is really a request and your Operator agent on OpenClaw will open a Trello card with the subject, due date, and checklist pulled from the body. When you send the reply it can move the card and add a comment with the sent text so the board stays aligned with the inbox.
It reaches both apps directly or through connectors like Composio MCP and Pipedream MCP, which handle the sign in and token refresh, so there is no Zap to build and no API keys to paste.

What your agent does in Trello
Add board
Creates a new Trello board; the 'name' parameter is required for creation, and various preferences can be customized or cloned from a source board.
Add card
Creates a new card in a Trello list. Only `idList` is required; `idBoard` is optional as the API determines the board from the list.
Add comment to card
Adds a new text comment, which can include @mentions, to a Trello card specified by its ID; file attachments are not supported via this action.
Add attachment to card

Add checklist to card via id

Add label to card
Adds an existing label to a Trello card; `idCard` identifies the card and `value` is the ID of the label to add. Both card and label must already exist.
How it works
Tell the agent what you want to happen between Gmail and Trello, for example to watch one and act in the other, or to keep the two in step. It reads what it needs from Gmail, works out what to do, and runs the matching action in Trello without you mapping a single field.
You can have it run once, on a schedule, or whenever something changes. Ask it for a status any time and it reads the latest from both apps back to you in the same chat.
Common questions about Gmail and Trello
- How do I connect Gmail and Trello to Operator?
- You authorize Gmail and Trello once each from your Operator dashboard. Operator holds both connections and refreshes the access tokens for you, so your agent keeps working across them without you signing in again.
- What can my agent do across Gmail and Trello?
- You describe the outcome in plain language and your agent works between the two, reading from one and acting in the other. It picks the right Gmail and Trello actions on its own, so you do not map fields or pick triggers.
- Can my agent keep Gmail and Trello in sync?
- Yes. It can watch Gmail and act in Trello, or keep both in step, reading from one and running the matching update in the other. This runs on demand when you ask or on a schedule you set.
- Do I need to build a workflow or write code?
- No. There is no workflow to build, no fields to map, and no API keys to paste. Operator manages both connections, and you give the agent instructions in plain language.
