Update the position of a list on a board. Use this tool to reorder lists on a board.
AI agents use update_list_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 state of a Trello board by reordering lists, but the change is fully reversible (lists can be reordered again to any previous position). There are no side effects beyond positional metadata updates, no data deletion, no code execution, and no financial impact. This is a straightforward Write operation with low severity due to its limited blast radius and reversibility.
From the tool's definition Tool description states "Update the position of a list on a board" and "reorder lists on a board" — these are modification operations that change list order.
Documented attack patterns abuse exactly the kind of access update_list_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_list_position:
{
"version": "1",
"default": "deny",
"tools": {
"update_list_position": {
"limits": [
{
"counter": "update_list_position_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_list_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.
