Each one returns a plan with a diff. Nothing moves until a person approves.
- Authenticated dashboard approval of one exact plain-text message and owned attachments
Customer SMTP email guardrail
Complete sender, recipients, body and attachment hashes are shown. SMTP acceptance is not inbox delivery. Email has no undo; unknown outcomes are never automatically replayed.
Plus complete diff previews, human approvals and the flight recorder on every connection. Live changes require a paid plan.

Try “Prepare this exact client email for human review.” Reports answer straight away. Anything that changes Customer SMTP email comes back as a plan for you to approve.
Safety
Hand AI the keys. Keep the brakes.
The same loop guards every MegaMCP connection: ask, see the diff, approve, undo.
Approval before every change
SMTP Email write tools never touch Customer SMTP email directly. They return a plan, and a person approves it in the dashboard, or in chat if an admin allows it.

FAQ
SMTP Email MCP server questions
Is there an official SMTP Email MCP server?
SMTP is an open standard rather than one vendor's product, so there is no single official SMTP MCP server; email MCP servers usually come from individual email providers. MegaMCP's SMTP connection sends one exact plain-text email from your own sender, and only after a person approves the complete message.
What is a SMTP Email MCP server?
An MCP (Model Context Protocol) server lets AI assistants such as Claude, ChatGPT and Cursor use SMTP Email through tools. MegaMCP's hosted SMTP Email MCP server gives your assistant 1 read tool and 1 write tool for your private send receipts, and every change waits for a human approval.
Does the SMTP Email MCP server work with ChatGPT?
Yes. MegaMCP is a remote MCP server with OAuth sign-in, so one URL works in ChatGPT (as an app, with developer mode on), Claude (as a custom connector), Cursor, Claude Code and VS Code. Your AI app's own plan decides whether it can add custom MCP servers.
Can it make changes to my SMTP Email account?
Yes, with your approval. It can propose plain-text emails changes. Each one comes back as a plan with a line-by-line diff and waits for a human before anything moves. Complete sender, recipients, body and attachment hashes are shown. SMTP acceptance is not inbox delivery. Email has no undo; unknown outcomes are never automatically replayed.
How do I connect SMTP Email to Claude or ChatGPT?
Use a dedicated customer SMTP sender on verified TLS or mandatory STARTTLS, fixed client binding, and admin sender-authority/data/cost attestation. Saving performs no login or send and starts disabled. Sender verification and provider quotas/charges remain customer responsibilities.
What does the SMTP Email MCP server cost?
Reading SMTP Email is free on MegaMCP's Free plan (100 reads a day, no card). Approved changes are included in every paid plan, from $19/month after a 5-day free trial, with unlimited runs and no credits. MegaMCP adds no markup: any subscription or API usage with the vendor stays between you and them.
Is my SMTP Email data safe?
Your Customer SMTP email credentials are encrypted at rest (AES-256-GCM) and bound to their connection, and MegaMCP never trains AI models on your data. Your AI only sees the accounts you switch on, members limited to certain clients only see those clients, and every tool call lands in the flight recorder.
