What archive_list does on Trello MCP Server
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.
Why archive_list is rated Medium
Archiving a Trello list modifies its state by marking it as archived/closed, but this action is reversible—archived lists can be unarchived. This makes it a Write operation rather than Destructive. The severity is medium because while the operation affects workflow and visibility, it does not permanently delete data and can be easily reversed.
From the tool's definition Tool name 'archive_list' and description 'Archive (close) a Trello list' indicate a reversible modification operation. Archiving is a state change that can be undone by unarchiving.
Attacks that exploit this kind of access
The rule that runs archive_list safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Trello MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For archive_list, this is the rule to start with:
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.
The button opens the PolicyLayer dashboard: create your workspace, connect Trello MCP Server, apply this rule, and every archive_list call is checked against it from then on.
