WHAT IT DOES

What create_tag does on Superthread Mcp Extended

WHY IT NEEDS A POLICY

Why create_tag needs a policy

The tool creates new tag objects in the system, which is a reversible modification of data. It does not execute arbitrary code, delete data, or involve financial transactions. Creation of tags is a standard Write operation with medium severity due to potential for spam or metadata pollution if misused, but the blast radius is limited since tags are organizational metadata rather than core data.

From the tool's definition Tool name 'create_tag' and description 'Create a new tag' indicates creation of new data. The description specifies parameters (name, color, optional project) for tag creation.
