What your agent reads

The tool description exactly as an MCP client receives it in tools/list — it doubles as the full behaviour of the endpoint.

Check whether an e-mail address is deliverable, without sending mail. result: valid (deliverable) · invalid · catch_all (the domain accepts everything — not provable) · unknown · unreachable (the domain does not accept mail: no MX, or its mail server does not answer) · not_found (no mailbox for that name) · skipped (the provider blocks verification from our network for now). Pending answers work like find_email.

Errors follow one format.
