WHY IT NEEDS A POLICY

Why create_a_project needs a policy

This tool creates a new Supabase project, which is a reversible Write operation. The severity is high because creating projects can incur financial costs, consume quotas, and create persistent infrastructure resources that require cleanup. However, it is categorized as Write rather than Financial because the tool itself does not directly transfer money—the financial impact is indirect through resource provisioning.

From the tool's definition Tool name is 'create_a_project' and description states 'Create a new Supabase project', indicating it creates a new resource.
