AI agents use trello_create_card to create or update resources in autoMate — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your autoMate environment.
Creating a card in Trello is a reversible write operation that modifies state in an external SaaS system. This falls under Write rather than higher severity categories since the action can be undone (card can be deleted). Severity is medium because misuse could clutter task management systems or create unwanted entries affecting team workflows, but the impact is contained to Trello and reversible.

"version": "1",
"default": "deny",
"tools": {
"trello_create_card": {
"limits": [
{
"counter": "trello_create_card_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}trello_create_card stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
