Three steps, nothing to install
It is a remote server: you add its address as a connector and sign in with your MailSenpai account.
Add the connector
In your assistant, add a custom MCP connector with the address https://mcp.mailsenpai.com/mcp.
Sign in
The authorization page opens: sign in with your MailSenpai email and password. OAuth 2.1 with PKCE, no API keys to copy.
Ask in chat
Ask for what you need. Campaigns are created as drafts; sending and deleting need your explicit confirmation.
Claude
Settings → Connectors → Add custom connector, then paste the address above.
ChatGPT
Add MailSenpai as a connector from the apps and connectors settings, where your plan allows custom MCP connectors.
Cursor and other clients
Add this to your MCP configuration:
{
"mcpServers": {
"mailsenpai": {
"type": "http",
"url": "https://mcp.mailsenpai.com/mcp"
}
}
}The assistant helps. You decide.
Drafts first
Campaigns created by the assistant start as drafts. Nothing is sent until you confirm.
Explicit confirmations
Sending needs confirm_send and deleting needs confirm_delete: the assistant has to ask you.
Your permissions, nothing more
The token only gets the permissions of your plan and role.
Every call logged
Every call is logged and subject to public rate limits.
Disconnect any time
Remove the connector from your client; access also expires on its own.
Data in the EU
Like the platform, the data stays in the European Union.

We are truly satisfied with MailSenpai’s services because they managed to interpret our particular email-marketing experimentation needs effectively and efficiently. As we are not experts, their Support Team trained our staff on the tools in a reasonable time for everyone. […]
EVERYTHING! Easy to use, innovative and complete features and above all the customer service and the dedicated coach! I strongly recommend this provider to everyone who wants to perform and scale their business at its best!!!
Competent Italian service
I tried several email marketing platforms (Mailchimp, ActiveCampaign) but MailSenpai is the one that convinced me most. Customer support is fast and super competent, they solved technical problems for me within a few hours. […]
The email marketing platform I was looking for
MailSenpai is truly one of the few companies that let you send large volumes of email and build automations other platforms don’t allow. It also offers support in Italian, which almost nobody does. […]

Frequently asked questions
Which assistants does it work with?
Claude, ChatGPT, Cursor and other clients that support remote MCP servers with OAuth.
Do I need to install anything?
No: it is a remote server. Add https://mcp.mailsenpai.com/mcp as a connector and sign in with your MailSenpai account.
Can the assistant send a campaign on its own?
No: campaigns start as drafts and sending needs explicit confirmation; the same goes for deletions.
How much does it cost?
The server costs nothing extra. You need AI access, which you can try with the free 30-day demo, or add to the Smart plan from €9.90/month + VAT (annual, up to 20,000 emails a month).
Where is the data?
In the European Union, like the platform. Privacy: https://mcp.mailsenpai.com/privacy.
How do I disconnect it?
Remove the connector from your client settings; access expires on its own, or contact support to revoke it immediately.
Can it send transactional emails for my app?
The MCP server manages the email marketing platform. For the transactional emails of apps and websites there is SMTP Senpai, our SMTP relay with servers in the EU.
