A self-hosted email service that gives AI agents their own inboxes, email addresses, threads, and message history. It can also prepare email as Markdown and search messages by meaning.

In plain words
What is it for?
Use it to create inboxes, send and receive email, manage conversations, retrieve threads, search messages, or connect services such as Mailgun, SES, SendGrid, and Resend.
Why use it?
It provides the persistent email storage and organization an email agent needs instead of making you build those parts yourself.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nornweave-api scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

NornWeave API

NornWeave is a self-hosted, open-source Inbox-as-a-Service API for AI agents. It provides a stateful email layer (Inboxes, Threads, History) and an intelligent layer (Markdown parsing, Semantic Search) optimized for LLMs.

Installation

# Python client
pip install nornweave-client

Setup

from nornweave_client import NornWeave

# Sync client
client = NornWeave(base_url="http://localhost:8000")

# Or async client
from nornweave_client import AsyncNornWeave
client = AsyncNornWeave(base_url="http://localhost:8000")

Inboxes

Create scalable inboxes on-demand. Each inbox has a unique email address based on your configured domain.

# Create inbox with username and display name
inbox = client.inboxes.create(
    name="Support",
    email_username="support"
)
# Result: [email protected]

# List all inboxes (paginated)
for inbox in client.inboxes.list():
    print(inbox.email_address)

# Get inbox by ID
inbox = client.inboxes.get(inbox_id="inbox-uuid")

# Delete inbox
client.inboxes.delete(inbox_id="inbox-uuid")

Async Usage

# Create inbox
inbox = await client.inboxes.create(
    name="Support",
    email_username="support"
)

# List inboxes with async iteration
async for inbox in client.inboxes.list():
    print(inbox.email_address)

# Get and delete
inbox = await client.inboxes.get(inbox_id="inbox-uuid")
await client.inboxes.delete(inbox_id="inbox-uuid")

Messages

Send and retrieve messages. NornWeave automatically converts content to Markdown for LLM consumption.

# Send message (body is Markdown)
response = client.messages.send(
    inbox_id="inbox-uuid",
    to=["[email protected]"],
    subject="Hello from my AI agent",
    body="# Welcome\n\nThis is a **markdown** email."
)
print(f"Message ID: {response.id}, Status: {response.status}")

# Reply to existing thread
response = client.messages.send(
    inbox_id="inbox-uuid",
    to=["[email protected]"],
    subject="Re: Hello",
    body="Thanks for your message!",
    reply_to_thread_id="thread-uuid"
)

# List messages for an inbox (paginated)
for message in client.messages.list(inbox_id="inbox-uuid"):
    print(f"[{message.direction}] {message.content_clean[:100]}")

# Get single message by ID
message = client.messages.get(message_id="message-uuid")
print(message.content_clean)  # LLM-ready markdown content

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
