Your boards, lists, and cards — fully automated

ProjectsProductivityCommunicationAutomationScheduling

Trello is the visual board-based task tracker that millions of teams use to move work through stages. Connect it to Actionist and your agents can create cards from any inbound signal, move them between lists as work progresses, assign members, post comments, and react to due dates — all without a human touching the board. Every card update, every list change, every checklist tick can trigger a downstream action across your entire stack.

Eliminates manual work. Agents eliminate the manual triage, card creation, member assignment, and status-update steps that eat 30–45 minutes per person every day.

Support ticket to resolved in 60 seconds

When a client email lands in Gmail and creates a support card, your agent reads the message, finds the right Trello board, creates a detailed card with label and assignee, posts the email as a comment, and pings the support lead in Slack — all before a human has scrolled to the message. Clients wait minutes, not hours, because the triage is already done.

How to plug Trello into Actionist

Pick the connection method that suits your environment.

The fastest path to Trello. Install one of the official Trello MCP servers and the agent reaches your boards, lists, and cards through a permissioned OAuth handshake — no token strings to copy, no credential rotation to manage.

1
Open the Apps tab

Find Trello in the Apps library and click Connect. MCP is selected by default — the agent will use the official mcp-server-trello.

2
Authorise in Trello

A Trello OAuth window opens. Log in and grant Actionist permission to read and write your boards — you choose which workspaces are in scope.

3
Test the connection

Actionist runs a read-only call to list your boards. A green tick confirms the handshake and the agent is ready to act.

FAQs

Questions about Trello + Actionist

How do I connect Trello to Actionist?
Open the Apps tab, find Trello, and click Connect. The default method is MCP — click through the OAuth prompt, grant access to your Trello workspace, and Actionist confirms the connection with a read-only board list call. The whole process takes under two minutes.
What credentials does the Trello integration need?
The MCP (recommended) path uses OAuth — you log in to Trello and grant scopes, no tokens to manage. The API Key fallback needs a Trello Power-Up API Key and a personal API Token, both generated at https://trello.com/power-ups/admin. The agent needs read and write permissions; read-only scopes will block card creation and updates.
Which Trello objects can the agent read and write?
The agent can read and write boards, lists, cards, checklists, checklist items, labels, attachments, comments, and board members. It can also read actions (the Trello audit log) and organisation records. The full catalog is 82 operations — see the Actions tab for the complete list.
What automations work well with Trello?
Common patterns: creating cards from inbound emails or form submissions, moving cards between lists when upstream systems change status, adding checklist items as tasks are discovered, assigning members based on label or department, and triggering notifications when cards go overdue. Trello pairs especially well with Gmail, Slack, HubSpot, and Google Sheets for full-stack task automation.
Are there rate limits I should know about?
Trello's API enforces 100 requests per 10 seconds per token and 300 requests per 10 seconds per IP. For high-volume automations (e.g. bulk card creation from a spreadsheet), the agent spaces requests automatically. If you hit the limit, you'll see a 429 error — add a short delay between batch operations to stay within quota.
How do I avoid trigger loops when the agent updates cards?
Trello's triggers fire on all changes, including those made by the integration user. To prevent loops: (1) Check the action's `idMemberCreator` in the New Activity trigger and skip processing when it matches your API token's member ID. (2) Use Card Moved to List instead of Card Updated — it only fires on explicit list changes, not on every field edit. Both safeguards stop the agent from reacting to its own writes.
Can the agent work across multiple Trello boards?
Yes. Every action that creates or reads a card takes a board ID parameter, so the agent can operate across all boards in the same workspace in a single workflow. Use Find Board or Find Board by ID to resolve board IDs dynamically — this keeps automations portable across workspaces without hardcoded IDs.
What happens if I disconnect Trello?
Existing cards and boards are unaffected — disconnecting removes the agent's credentials but does not modify your Trello data. Scheduled or trigger-based workflows that depend on Trello will stop firing and log a connection error. Reconnect via the Apps tab to resume; all workflows resume automatically without reconfiguration.
