snailLOCAL SANDBOX CONNECTION
Connect your assistant
This grants agent access to your simulated account. It does not approve a letter or authorize funding.
A little slower. A little more meaningful.
Letters, with a human
in the loop.
Review what your agent prepared. Approve the exact recipient, proof and price. Keep every credit accounted for.
Sign in to your mail desk
Your verified account keeps letters, approvals and credits together.
Local test mail capture. No email was sent. These links exist only on localhost and are never exposed by production.

Your first letter, in three steps.
- Prepare a draft or ask your assistant for a quote.
- Review the recipient, full content and simulated price. Add simulated credits in Wallet if needed.
- Explicitly approve, submit, then reopen the same order from History.

Remote MCP:
Bearer credentials are scoped, hashed, expiring and revocable. No real credential is generated or active in this build. Credential issuance and production auth/email setup are activation prerequisites. The separate OAuth sandbox is tested locally and disabled by default; hosted assistant onboarding is not configured.
The remote MCP offers fifteen tools: quotes, approved submissions, order status, wallet, top-up requests/status and credit history. Human-only actions happen here.
Try the local agent workflow
- In the project directory, run
npm run smokefor an automatic official-SDK workflow with fictional fixtures. - For a local stdio client, use
npm run mcp. Stdio approval is an unverified demo assertion. - Remote assistants require an issued scoped credential or reviewed OAuth client setup. This build does not issue a usable credential from this screen.
- Ask for a quote, open its private review link here, approve the unchanged proof, then return to the assistant to submit with a stable idempotency key.
Local operational health
