AI agents use archive_list to create or update resources in Trello MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Trello MCP Server environment.
Archiving a list changes its state in Trello but is not destructive since the data remains intact and can be recovered by unarchiving. This makes it a Write operation rather than Destructive. The severity is medium because while the action is reversible, archiving a list could disrupt workflow if an AI agent archives the wrong list without clear intent, affecting team collaboration on that list's cards.
From the tool's definition archive_list: Archive a list - this modifies the state of a Trello list by archiving it, which is a reversible action (lists can be unarchived).
Documented attack patterns abuse exactly the kind of access archive_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Trello MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for archive_list:
{
"version": "1",
"default": "deny",
"tools": {
"archive_list": {
"limits": [
{
"counter": "archive_list_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}archive_list 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.

Archive a list. It is categorised as a Write tool in the Trello MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Trello MCP Server MCP server in PolicyLayer and add a rule for archive_list: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Trello MCP Server. Nothing to install.
archive_list is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the archive_list rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for archive_list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
archive_list is provided by the Trello MCP Server MCP server (lzvxck/trello-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Trello MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
