Openagentemail runs on your own machine — the client starts it, so there is no endpoint to ping. 118 installs a week from npm. Last commit 28 Oct 2026.
Unlimited agent mailboxes — create identities, read/wait for mail, extract OTPs, send email.
What the code does

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.
return spawnSync(finder, [command], { stdio: 'ignore' }).status === 0;

This code can reach further than it looks
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
