The sandbox gives you a Motor Block on *.sandbox.motorical.com with outbound locked to an allowlist. Send real mail to yourself before you own a domain, then convert onto a verified one.
Sends default to a dry run, and a real send needs a second, explicit confirmation — two signals, so an agent cannot mail your users by accident. Destructive Motor Block actions are confirmation-gated too.
Separate servers cover sending, analytics, domains, sandbox, webhooks and Motor Block management. Connect only what the task needs; access is granted per Motor Block.
The server registers the live OpenAPI document as an MCP resource, alongside llms.txt. Your agent works from the current contract instead of guessing at it.
Message timelines and delivery events are scoped to the Motor Block the agent is working in. Debugging one project never means reading another project’s traffic.
The agent adds a domain and gets the exact DNS records back, verifies ownership, and checks DNS until the domain is send-ready.
Add the hosted server to your agent and sign in with OAuth. There is nothing to install.
Ask the agent to provision a sandbox — an outbound-locked Motor Block with its own credentials.
A dry run validates the payload. Confirm to actually deliver, then read the message timeline back.
Add your domain, verify it, check DNS, and convert the sandbox Motor Block onto it.

Which agents does this work with?
Any MCP client that supports remote servers with OAuth — Claude and Cursor are the common ones. A local stdio package, @motorical/mcp, is also available for clients that only run local servers.
Do I need to install anything?
No. The hosted servers need only a URL and an OAuth sign-in. The local package is optional.
Can the agent send real email to real people?
Only deliberately. Sends are dry-run by default, and a sandbox Motor Block is outbound-locked to an allowlist you control, so the blast radius before you convert to a real domain is limited to addresses you have approved.
Do I need a paid plan to try it?
No. The developer sandbox is unpaid. Converting a sandbox Motor Block onto a domain you own requires an active plan.
