WHY IT NEEDS A POLICY

Why create_magic_link needs a policy

This tool creates a new authentication credential (magic link) which is a reversible write operation—the link can be invalidated or revoked. While it doesn't directly modify marketplace data like listings, it does create a new access mechanism that increases the account surface area. The requirement for an API key suggests restricted access, lowering severity from high to medium.

From the tool's definition Tool is named 'create_magic_link' and described as creating 'a magic link for owner claim.' Magic links are credentials that grant access; creating one modifies the authentication/authorization state of an account by enabling a new access mechanism.
