Pinned tool definitions (28)
| Tool | Description |
|---|---|
| listDomains | List all inbound domains for the organization, both verified and unverified. Each domain includes its verification status and DNS records. Use before addDomain to check whether a domain is already claimed. |
| addDomain | 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... |
| verifyDomain | 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... |
| downloadDomainZoneFile | Download a BIND-format DNS zone file for a domain. Useful when users want to import all required DNS records at once rather than copying them individually. Returns plain text in BIND zone file format. |
| getAccount | Use this when you need the authenticated Primitive account summary, including email, plan, onboarding state, and webhook secret rotation time. |
| getInboxStatus | Use this when the user asks whether inbound email is ready or needs setup. Returns domains, routes, deployed Functions, and recent inbound activity. |
| getOutboundStatus | What can I send FROM? Lists this account's verified outbound (sendable) domains plus any domains still pending DNS verification, with next actions. Call this BEFORE sendEmail to pick a valid `from` domain — the account email is not... |
| listEmails | Use this when you need to browse inbound emails received at verified domains with cursor pagination, status filters, date filters, or sender/recipient search. |
| searchEmails | Use this when you need to find inbound emails with structured filters or full-text matching. Use sort=received_at_asc plus date_from for new-mail polling. |
| getEmail | Use this when you need full details for one inbound email ID, including parsed bodies, threading metadata, SMTP envelope, webhook state, and replies. |
| replyToEmail | Use this when the user has selected a specific inbound email and confirmed a reply. Sends real outbound email with threading handled server-side. |
| sendEmail | 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. |
| sendEmailDemo | Send a SIMULATED email with no account required. Validates the body against the exact same schema as sendEmail, then returns a realistic synthetic success envelope (demo: true) — it never actually sends, queues, or stores anything. Use... |
| listSentEmails | List outbound emails sent by this org, with cursor pagination and filters. Bodies are omitted from list rows to keep responses small — use getSentEmail to fetch a specific row with full body. Useful for auditing delivery status, finding... |
| getSentEmail | Get the full record for a single sent email by id, including body_text and body_html. Use to inspect delivery details for a specific send — e.g. the SMTP response on a bounced row, or the gate denial reason on a gate_denied row. |
| awaitReply | Get the threaded reply to a sent email — the canonical 'did they reply yet?' call. Pass the sent email's id (from a sendEmail response). With wait=true it long-polls up to wait_timeout_ms for the reply to arrive (synchronous... |
| getConversation | Get the full conversation an inbound email belongs to as ordered, chat-model-ready turns with bodies. Each message is oldest-first with a direction (inbound/outbound) and a derived role (inbound→user, outbound→assistant). For a... |
| getThread | Get a conversation thread by id: metadata plus all inbound and outbound messages interleaved oldest-first. Each message has a direction (inbound/outbound) and id; fetch inbound message bodies via getEmail, or outbound bodies via... |
| downloadEmailAttachments | Download all attachments for an inbound email as a gzip-compressed tar archive. Returns the archive as a base64-encoded string along with the attachment count and SHA-256 digest. Prefer getEmail first to check the attachment manifest... |
| listEndpoints | List all active webhook endpoints for the organization. Each endpoint shows its URL, enabled state, and optional domain restriction. |
| createEndpoint | Create a webhook endpoint to receive email.received events. If an endpoint with the same URL already exists but is deactivated, it is reactivated. After creating, call testEndpoint to confirm your signature verifier accepts the payload. |
| deleteEndpoint | Soft-delete a webhook endpoint. The endpoint will no longer receive deliveries. |
| testEndpoint | Send a sample email.received event to a webhook endpoint to verify your signature verifier. Rate limited to 4/min and 30/hr. Successful deliveries and verified-domain endpoints are exempt. |
| listFilters | List all whitelist and blocklist filter rules for the organization. |
| createFilter | Create a whitelist or blocklist filter rule. Patterns are stored lowercase. Per-domain filters require a Pro plan. |
| deleteFilter | Delete a filter rule. |
| listWebhookDeliveries | List webhook delivery attempts with pagination and filters. Each delivery includes the target endpoint and a nested email object with sender/recipient/subject. Useful for diagnosing delivery failures or confirming a specific email was delivered. |
| replayWebhookDelivery | Re-send a stored webhook payload from a previous delivery attempt to its original endpoint. Rate limited per org (burst + sustained windows, shared budget with email webhook replays). |
