Can I choose which email account the folder is created under?

Yes. Just name the account in your prompt — for example, "under my iCloud account" or "in Gmail" — and the AI will create the folder in that specific account. If you don't specify, it uses your default mailbox.

Does this work with Gmail and Exchange accounts in Mail.app?

Yes. create_email_folder works with any account configured in Mail.app, including iCloud, Gmail, Exchange and other IMAP accounts. The folder is created within that account's mailbox structure.

Is my email data sent to a server?

No. LMCP runs entirely on your Mac and talks to Mail.app locally. No email content, account names, or folder data is ever uploaded or stored on a remote server.

Create a Mail Folder with AI on Mac — create_email

The create_email_folder tool lets an AI assistant create a brand-new mailbox folder inside Mail.app on your Mac. Instead of right-clicking in the Mail sidebar and typing a name yourself, you just describe what you want. For example, you can type: "Create a new Mail folder called Tax 2026 under my iCloud account." The AI calls create_email_folder, and the folder appears instantly in your real Mail.app — ready to receive messages.

This is part of LMCP, a free, native macOS MCP server with 150+ tools. It connects your AI assistant to the real apps you already use — no API keys, no cloud accounts, and nothing stored on a remote server. Download LMCP to get started.

Which AI agents work?

Both desktop AI clients and web-based AIs can use create_email_folder:

Desktop clients — Claude Desktop, Cursor, VS Code (GitHub Copilot), Windsurf and Zed auto-configure through a local stdio connection. LMCP wires itself in automatically.
Web AIs — ChatGPT, Claude.ai (web), Grok and Perplexity connect through the LMCP Cloud Relay connector, which securely bridges the web assistant to your local Mac.

Whichever agent you prefer, the same tool is exposed and works identically.

Automation

Creating a folder is rarely the end goal — it's usually a first step. create_email_folder chains naturally with other LMCP Mail tools. A typical flow: create the folder, then use move_email to file matching messages into it, or set up a triage where the AI reads your inbox with list_emails, sorts receipts into a new "Receipts" folder, and replies with send_email. You can ask: "Make a folder called Q2 Invoices and move every email from billing@ into it." The AI handles folder creation and message moving in a single conversation.

Context

Because LMCP runs on your Mac, the AI works with your real Mail.app accounts and existing folder structure — not a sandboxed copy. It can see which accounts you have (iCloud, Gmail, Exchange) and create the folder under the right one. The assistant operates on the same mailboxes you see every day, so the result is exactly what you'd get doing it by hand.

Productivity

Organizing a mailbox by hand means right-clicking, naming, and repeating for every account and category. With create_email_folder, a single sentence builds the structure you want — and combined with move and search tools, the AI can reorganize months of email in seconds. For anyone who keeps a tidy inbox for projects, clients, or tax season, this turns a tedious chore into a one-line request.

Privacy & GDPR

Everything happens locally on your Mac. LMCP creates the folder directly through Mail.app — your email, account names, and folder data never leave your machine and are never copied to any LMCP server. There are no API keys to hand over and no cloud sync. This local-first design makes LMCP GDPR-compliant by architecture: the data simply never travels.
