move-card · Trello MCP Server MCP: Risk & Policy

WHAT IT DOES

What move-card does on Trello MCP Server

AI agents use move-card 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 IT NEEDS A POLICY

Why move-card needs a policy

Moving a card changes its position/list assignment but does not delete data or execute arbitrary external operations. The action is reversible—cards can be moved again to restore prior state. This qualifies as Write rather than Execute (no command execution), Destructive (reversible), or Read (modifies state).

From the tool's definition Tool name 'move-card' paired with server description stating it 'Supports creating, moving, archiving cards' indicates the tool modifies card state by relocating it within Trello.

move-card Rate-limited

move-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.
