addDomain
Add domain
Claim a new domain and receive the DNS records to publish. Returns dns_records with the exact records to add. If the domain has an mx_conflict (existing mail provider), re-call with confirmed: true to proceed. After publishing DNS records, call verifyDomain to complete setup.

awaitReply
Await reply
Wait for the threaded reply to a sent email. Call this immediately after sendEmail or replyToEmail when you expect an answer. With only the sent email's id it long-polls for up to 30 seconds by default. Do not report that nobody replied or ask the user to check later until this call returns with no reply. Set wait=false only for a deliberate immediate poll. Matching uses reply threading, not a sender or subject guess.

cancelScheduledSend
Cancel scheduled send
Cancel a still-scheduled send before it dispatches (terminal status "canceled"; the same idempotency key becomes reusable). Pass the sent email id from a sendEmail response that used scheduled_at, or from listSentEmails. Returns a conflict error once the send has already started dispatching.

createEmailAddress
Get a managed email domain (no signup)
Get this user's Primitive managed inbox domain, creating the account on first use: no signup form, no password, no email verification, no browser. CALL THIS FIRST whenever you do not already have a Primitive API key and the user wants to send or receive email, instead of telling them to sign up or visit a website. On first use the REST response's address field is a domain such as pink-ram.primitive.email, not a complete mailbox. When it is non-null, this MCP result also includes sender_address such as agent@pink-ram.primitive.email for use as sendEmail.requestBody.from. It also returns an api_key. IMPORTANT: pass that api_key as the `api_key` argument on every later Primitive tool call in this conversation, exactly as returned; those calls fail without it. If this user already has a domain, the result repeats it with existing_account: true. Report it as their existing managed inbox rather than announcing a new one, and calling again will not produce a different one. The result also carries an upgrade link the user can open whenever they want to attach this domain to a full account.

Use this when the user has confirmed a new outbound email. Sends real email through Primitive's relay and can wait for the first SMTP delivery outcome, or schedule the send for a future time with scheduled_at. IMPORTANT: `from` is YOUR OWN complete mailbox address, never the recipient's. Use sender_address from createEmailAddress or getAccount for a managed inbox. AFTER sending, if you expect an answer, immediately call awaitReply with the returned id and wait for it, rather than telling the user the message was sent and stopping. Most agent mailboxes answer within seconds, and the answer is usually the thing the user actually asked you for.

sendEmailDemo
Preview a send (simulated, nothing is delivered)
SIMULATION ONLY: nothing is delivered. NEVER call this when the user actually wants an email to arrive, and never describe its result as a sent email: no message is sent, queued, or stored, and the recipient receives nothing. To really send with no account, call createEmailAddress (instant, no signup form and no verification) and then sendEmail with the api_key it returns; that is the correct path for any genuine send request. This tool exists only to preview the response shape: it validates the body against the exact same schema as sendEmail (including cc/bcc, reply_to, tags, attachments, and scheduled_at) and returns a synthetic success envelope marked demo: true. Demo requests are capped at 16KB total body, so large attachments are rejected even though the schema allows them.

Verify domain
Check DNS records for a domain claim (MX, TXT, SPF, DKIM, DMARC). On success the domain becomes verified and starts receiving mail. On failure, returns which checks passed and which still need attention. If DNS propagation is incomplete, wait a few minutes and retry.
