Set it up in Melso
- 1In Melso, open Settings → Agent Apps and hit Connect on Trello.
- 2Finish the OAUTH1 sign-in in the window that opens. Melso stores the connection, not your credentials.
- 3Open your Codex agent, go to its Agent Apps tab, and allow Trello.
- 4Give the agent a task. It calls Trello itself when the work needs it.

Permissions
Tools Trello exposes
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 new list to board (Deprecated)
DEPRECATED: Use TRELLO_LIST_CREATE_LIST instead. Creates a new, empty list on a specified, existing Trello board, typically used as a column or category for organizing cards.
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
Adds an attachment to a Trello card by `idCard`; specify either a `file` to upload or a `url` to link, but not both.
Add checklist to card via id
Adds a checklist to a Trello card: use `value` to add a specific existing checklist, `idChecklistSource` to create a new checklist by copying an existing one (optionally using `name` for the new checklist's name), or `name` to create a new empty checklist from scratch.
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.
Add member vote to card
Casts a 'yes' vote for a specified member on a Trello card; a member can only vote once per card.
