primitif — infrastructure for AI agents

Mail

Give your agent a real email address. Send, receive, reply, manage threads — then throw the mailbox away.

Ephemeral mailboxes: Create mailboxes on-demand with an optional TTL. They auto-expire or can be destroyed when the agent is done.
Send & reply: Send plain-text or HTML emails. Reply in-thread to keep conversation context. Every send returns a thread ID.
Inbox, threads & attachments: Paginated inbox with unread filter. Threaded view groups messages. Download inbound file attachments programmatically.
Call the MCP: Expose mail capabilities as MCP tools. Any agent framework can discover and call them automatically.
Get notified: Real-time webhooks on inbound messages. Signed payloads with timestamp-based replay protection.

from primitif import Primitif

p = Primitif()
mb = p.mail.create_mailbox()
# amber-llama@mail.primitif.ai

mb.send(
    to="user@example.com",
    subject="Welcome",
    body_text="Your account is ready."
)

for msg in mb.inbox().auto_paging_iter():
    mb.reply(msg.id, body_text="Got it!")▌

Native integration with Approval

Approval

Pause your agent before dangerous actions. A human reviews the request with full context, approves or rejects, and the agent moves on.

One API call: Gate any action with a single call. Returns instantly with a pending status — non-blocking by design.
Approval URL: Every request gets a shareable link. Reviewers open it in their browser — no login, no app install.
Rich context: Attach arbitrary JSON metadata so reviewers see the full picture — user IDs, amounts, reasons.
Get notified: Webhook, email, Slack — get alerted instantly when a human approves or rejects. Signed payloads included.
Call the MCP: Expose approval capabilities as MCP tools. Any agent framework can discover and call them automatically.

Task

Structured tracking for async work. Create a task, set the rules, walk away. Task manages the lifecycle. Perfect for coordinating a fleet of agents.

Status lifecycle: pending → active → waiting → resolved | expired | failed. Every state change fires a webhook.
Chase engine: Automated follow-ups on a schedule, through Mail or webhooks. Set the interval and max — Task handles the rest.
Resolution triggers: Close automatically on inbound email, webhook event, API call, or approval decision. No polling.
Escalation rules: If no resolution by deadline, notify, reassign, or trigger an approval gate. Deadlines that actually work.
Batch operations: Create hundreds of tasks, track as a campaign, get aggregate status. Built for volume.

Anon

One flag. Zero PII in your prompts.

Every email and document entering your LLM context carries names, payment info, contact details. anon=True scrubs it before your agent sees it.
