What does sendEmail do?

Send an email. It is one of the tools The Cloud MCP server gives every connected AI.

How do I use sendEmail from Claude or ChatGPT?

Connect your AI to The Cloud at https://mcp.thecloud.so/mcp and sign in once. Then ask Claude, ChatGPT, Cursor or any AI connected to The Cloud "email X", and it calls sendEmail.

Is sendEmail safe to let an AI call?

sendEmail deletes or sends, and calling it again does not undo it, so a careful client confirms with you before it runs. It reaches a system outside The Cloud on your behalf.

Arguments

blocksobject[]optionalStructured rich email body. When present, it wins over richBody and body for the HTML part; bodyHtml wins over it.

bodyHtmlstringoptionalYour own finished HTML email (a designed transactional email: receipt, confirmation, welcome) sent 1:1 as the HTML part. Precedence: bodyHtml wins over blocks and richBody for the HTML part; `body` is the explicit text part, else the text…

acknowledgedReasonstringoptionalWhy the acknowledged check is relaxed for this send, in one line. Logged with the rail and the phrases it let through.
confirmbooleanoptionalRequired with delivery send.
deliverystringoptional"hold" (default) sends nothing; "send" needs confirm:true.
allowPrivateLinksobjectoptionalSend Cloud links the recipient can't open, on purpose. The reason is recorded on this operation.
accountIdstringoptionalAlias of `from`, an accountId from listMailAccounts; wins when both are given.
attachmentsobject[]optionalCloud files to attach, in order: up to 20 files, 25 MB in total. Page exports are not attachable, so attach the PDF as a Cloud file if there is one. Only promise an attachment after the result comes back with it in `attached`.
bccstringoptionalBCC email address (optional)
ccstringoptionalCC email address (optional)
channelstringoptional"email" sends even when their channel of record differs.
docContractstringoptionalThe type-slug of the doc contract this is filed under (e.g. "handoff-memo"), when it is a staple rather than ordinary prose. The server validates the text against that contract and refuses a malformed one, handing back the contract's…
fromstringoptionalAccount to send AS: "shop-sender", or an accountId or email from listMailAccounts (always that Gmail account). Omit for the Space's verified shop sender, then the primary Gmail.

overridebooleanoptionalSend to a suppressed, newsletter-pool or 14-day-touched recipient anyway. ONLY on the user's explicit word; recorded as an override. A reply clears the touch check itself.
