copy_board · Miro MCP Server MCP: Risk & Policy

WHAT IT DOES

What copy_board does on Miro MCP Server

AI agents use copy_board to create or update resources in Miro MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Miro MCP Server environment.

WHY IT NEEDS A POLICY

Why copy_board needs a policy

Copying a board creates new data structures and potentially duplicates content, which is a Write operation. It is reversible (the copied board can be deleted). The severity is medium because while it doesn't destroy data or move money, it does create organizational artifacts that could consume resources and require cleanup.

From the tool's definition Tool name 'copy_board' and description 'Copy an existing board' indicate creation of a new resource (board) by duplicating an existing one. This is a reversible write operation that modifies organizational state.

copy_board Rate-limited

copy_board 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.
