create_board · Superthread Mcp Extended MCP: Risk & Policy

WHAT IT DOES

What create_board does on Superthread Mcp Extended

AI agents use create_board to create or update resources in Superthread Mcp Extended — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Superthread Mcp Extended environment.

WHY IT NEEDS A POLICY

Why create_board needs a policy

Creating a board is a reversible Write operation: it adds a new entity to the system but can be undone (the board can be deleted or archived). It does not execute arbitrary code, delete data irreversibly, or move money. The medium severity reflects that an AI agent could create many boards or unwanted organizational structures, but the action is bounded by authentication requirements and reversibility.

From the tool's definition Tool description states "Creates a new board" — a creation operation that modifies the system state by adding a new resource. Requires admin/owner privileges, indicating intentional access control.
