Mailcheck
for LuumenAI
Check an address or a domain before your system trusts it
Ask about any address or sending domain and get an answer in the terminal. MAILCHECK_VERIFY_EMAIL tells you whether an address is worth sending to. MAILCHECK_VALIDATE_DOMAIN covers disposability, MX records, domain age, and spam indicators. Useful when a bounce spike, a signup flood, or a failed notification needs explaining. Connected with an API key. Read-only.

Questions
Authorize once with API token. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
No. Every one of the 2 tools LuumenAI has for Mailcheck is read-only, so it can answer questions from Mailcheck but cannot change anything in it. Read actions still follow the configured access and approval policy, and are recorded on the audit trail.
You decide. Access is granted per agent, skill, and team, and per environment — production is not staging.
Every call to Mailcheck is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
