Scored across 1 tool
There is only one tool, so there is no possibility of the agent selecting the wrong tool. Its purpose (email deliverability verification) is stated unambiguously in the description.
The single tool uses a clear snake_case verb_noun-style name (email_verify) that matches the server's domain. With one tool there is no opportunity for convention mixing.
One tool is thin for a server surface, but the scope here is genuinely narrow (a single verification call that already bundles syntax, MX, disposable, SPF/DMARC and a verdict). It is borderline rather than mismatched, since batching up to 25 addresses removes the need for a separate bulk tool.
The tool covers the main verification signals (syntax, MX/A fallback, disposable, role, free-mail, SPF, DMARC, verdict) and honestly documents that mailbox existence cannot be confirmed. Minor gaps remain, such as catch-all detection or blocklist checks, but the core workflow has no dead ends.
