WHY IT NEEDS A POLICY

Why add_servers_to_tenant needs a policy

This tool creates or modifies tenant configuration by adding MCP servers. It is a reversible Write operation (servers can typically be removed), but carries high severity due to the potential security implications of adding servers to a tenant—an attacker could add malicious or unauthorized MCP servers that grant access to unintended resources or capabilities. The blast radius is significant in a multi-tenant system.
