WHAT IT DOES

What verify_credentials does on Lightpaper Mcp

WHY IT NEEDS A POLICY

Why verify_credentials needs a policy

This tool writes/submits credential data to an account, creating or modifying profile information. It is reversible (credentials can presumably be removed or updated), so it falls under Write rather than Destructive. Misuse could allow false credentials to be submitted, affecting account trustworthiness, hence medium severity.
