Server tool list (23)

Raw names from tools/list. Only developers need these.

check_domainsCheck whether domain names are available to register (up to 50 domains per call; 20 for anonymous calls).
check_copyCheck an email subject and body for spam trigger words before sending.
list_domainsList the workspace's sending domains with status, mailbox count and, for connected domains, DNS status and nameservers.
list_mailboxesList the workspace's mailboxes (address, sender name, status). Never returns credentials.
get_warmup_statusWarm-up progress per mailbox (state, days warming, ready flag, ready date, inbox rate) and a workspace summary. Mailboxes can send campaigns once ready.
list_sequencersList the workspace's connected sequencer accounts (Instantly, Smartlead) that mailboxes can be exported to.
preflight_campaignCheck whether a campaign can launch: sequence, contacts, attached mailboxes and their warm-up. Returns blocking checks with hints.
get_campaign_statsSending and engagement stats for one campaign (sent, replies, bounces).
list_repliesList recent threads where a contact replied (subject, sender, short snippet, reply intent). Paginate with cursor.
connect_own_domainsConnect domains the user already owns (free): returns the nameservers the user must set at their registrar. Calling again with the same domains is safe.
start_warmupStart warm-up for mailboxes. Retrying with the same mailboxes the same day does not start a second operation.
create_campaignCreate a campaign as a draft. Nothing is sent until launch_campaign.
upsert_campaign_stepAdd an email step to a campaign sequence, or update one (by step_id, or by order when a step with that order exists). delay_days is the wait after this step before the next one.
import_campaign_contactsImport contacts into a campaign from CSV text (header row with an email column; other columns become variables; up to 10000 rows). Pass import_id alone to check a previous import.
attach_campaign_mailboxesAttach mailboxes to a campaign for sending. Only mailboxes that finished warm-up are accepted.
pause_campaignStop a campaign from sending. Safe to call again.
launch_campaignStart sending a campaign to its contacts. Refused unless preflight is green and every attached mailbox finished warm-up. Requires confirm=true after the user explicitly agrees.
export_mailboxes_to_sequencerSend mailboxes' login credentials (SMTP/IMAP) to the user's third-party sequencer account (Instantly or Smartlead, from list_sequencers) so it can send from them. Omit mailboxes to export all eligible ones. Requires confirm=true after the user explicitly agrees.
get_pricingCurrent prices: mailbox monthly price and minimum, domain prices by TLD, card processing fee rule, worked examples.
get_account_statusWhat the workspace has (subscription, domains and mailboxes by state, warm-up, open orders, campaigns) and next_action: the one thing to do next. Start here.
quote_orderPrice new domains and mailboxes server-side. Creates a 15-minute quote; registers and charges nothing. Show human_summary to the user exactly before create_checkout. Ordering domains needs registrant with every one of: first_name, last_name, real_address, city, state_province, postal_code, country, phone, organization_name, job_title (email_address optional); collect them from the user upfront.
create_checkoutTurn a quote the user explicitly confirmed into a Stripe payment page. Charges nothing: the user pays on the page. Requires confirm=true and the quote's due_now_cents.
get_orderStatus of an order (payment, per-domain and per-mailbox setup, warm-up estimate) by order_id; without order_id, lists the workspace's recent orders.
