Update the position of a checklist on a card. Use this tool to reorder checklists on a card.
AI agents use update_checklist_position to create or update resources in Trello — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trello environment.
This tool modifies the position attribute of a checklist, which is a reversible change. The user can reorder the checklist again to restore the previous state. It does not delete data (ruling out Destructive), does not execute arbitrary code or commands (ruling out Execute), does not create new data (Write rather than Create-specific), and has no financial implications.
From the tool's definition Tool description states 'Update the position of a checklist on a card' and 'reorder checklists on a card' — these are modification operations that change the order/state of existing data reversibly.
Documented attack patterns abuse exactly the kind of access update_checklist_position gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trello, and nothing reaches the server without passing your rules. This is the rule we recommend for update_checklist_position:
{
"version": "1",
"default": "deny",
"tools": {
"update_checklist_position": {
"limits": [
{
"counter": "update_checklist_position_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_checklist_position 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.
