LotsMail MCP server URL
https://api.lotsmail.to/mcpOr let Claude Code guide the setup: send it this prompt
Read https://lotsmail.to/skill.md and help me connect LotsMail for you.What Claude Code can do with LotsMail
Once connected, Claude Code can:
- Read and search your mailboxes: list conversations by folder, open a whole conversation and find messages by person, subject or text.
- Write drafts and reply drafts that wait in Drafts for you to review and send.
- Send, reply and send a draft, once you have turned sending on for that mailbox, and check whether each message was delivered.
- Mark messages read or unread, star them and move them between inbox, archive, trash and spam.
- Start domain setup and show how your domains are paid for. Domains, DNS, team access and agent permissions stay yours, in the dashboard.
The LotsMail dashboard does the whole job too: a full inbox on every device, plus domains, mailboxes, team and agent permissions. Your agent for speed, the dashboard for control.
You need
- Claude Code with a Claude plan
- A LotsMail account. You can create one during sign-in.
Connect Claude Code to LotsMail
Add the server
Run this in your terminal. It adds LotsMail to the current project; nothing else to install.
claude mcp add --transport http lots-mail https://api.lotsmail.to/mcpclaude mcp add --transport http --scope user lots-mail https://api.lotsmail.to/mcpSign in from Claude Code
Start Claude Code and run /mcp. Select lots-mail, choose Authenticate, then choose Allow on the LotsMail page that opens in your browser.
/mcpCheck the connection
Back in Claude Code, ask a read-only question to confirm the tools work.
List my LotsMail mailboxes
What to ask next
- “What came in for sales@ today? Summarise anything that needs a reply.”
- “Draft a reply to the latest message from the supplier and leave it for me to check.”
- “Find last month’s invoice from our supplier and tell me the amount and due date.”
- “Check whether my last email to Acme was delivered.”
If something goes wrong
- lots-mail shows as needing authentication
- Run /mcp, select lots-mail and choose Authenticate, or run claude mcp login lots-mail in your terminal.
- The browser says Claude Code registered itself and is not verified
- That is normal for Claude Code: it registers with each MCP server and receives the sign-in on your own computer. Allow it when the return address is localhost.

Claude Code and LotsMail: questions
How do I connect Claude Code to LotsMail?
Follow the Claude Code setup above to add https://api.lotsmail.to/mcp. Complete sign-in using the authentication method shown. Then ask “List my LotsMail mailboxes”.
Can I add LotsMail to every Claude Code project?
Yes. Use the second command in step 1 (the --scope user variant) to add LotsMail for every project on your computer instead of the current one.
Do I need an API key to use LotsMail with Claude Code?
No. Claude Code signs in to LotsMail in your browser. API keys are for the REST API, for scripts and your own apps.
What does LotsMail cost?
Current plans and prices are on https://lotsmail.to/pricing. Your agent’s own plan or usage fees are separate.
Can my agent send email without me?
Only if you turn on sending for that mailbox. Sending is off until you do. With read or draft access your agent can search, read and write drafts that wait in Drafts for you to review and send.
Which mailboxes can my agent open?
Only the mailboxes you can open yourself. For each one you choose what agents may do: read and search, write drafts, or send. Owners do not get private mailboxes by default.
Can I limit who my agent emails?
Yes. A mailbox can be restricted to a list of addresses it may send to, and any other recipient refuses the whole send. Only a workspace owner or admin changes restrictions, in the dashboard.
Can my agent change my domain or DNS?
No. It can start domain setup, which gives you the steps and the dashboard link. Domains, DNS, billing, team access and agent permissions stay with you, in the dashboard.
