Spacemail by NWD runs on your own machine — the client starts it, so there is no endpoint to ping. 569 installs a week from npm. Last commit 2 Nov 2026.
Check, search, read and draft replies to Spacemail (Spaceship) emails, across several mailboxes.
What the code does
We read the source, 4 d ago · rules 995398eba69f
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.
execFileSync(cli, ["mcp", "remove", SERVER_NAME, "-s", "user"], { stdio: "ignore" });
Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
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.

<SPACEMAIL_EMAIL> (Your Spacemail address. For more mailboxes use SPACEMAIL_1_EMAIL, SPACEMAIL_2_EMAIL and so on), <SPACEMAIL_PASSWORD> (The mailbox password (not your Spaceship account password)).
The author’s registry entry marks them as required.
Optional settings from the registry entry, left out of the block above:
SPACEMAIL_LABEL (A short nickname for the mailbox, e.g. Support), SPACEMAIL_ALLOW_SEND (Set to true to let Claude send emails. Off by default, so replies are saved as drafts).
