PrivateEmail MCP

PrivateEmail MCP is a Model Context Protocol server for Namecheap PrivateEmail. It connects to mail.privateemail.com over IMAP and SMTP so Claude Code can read inboxes, search mail, draft replies, send messages, manage folders, and work with drafts.

This server is built for the Namecheap email provider called PrivateEmail. It is session scoped by design. Everything runs while Claude Code is connected to the server. There are no background workers, schedulers, or durable campaign daemons.

What it does

• Reads inbox messages, threads, and attachments

• Searches mail by sender, recipient, subject, body text, and date filters

• Sends new emails

• Replies and forwards while preserving thread headers

• Saves and sends drafts

• Moves, copies, deletes, and marks messages

• Creates, renames, and deletes folders

• Exposes inbox context as MCP resources

• Exposes reusable prompts for summarizing inboxes and drafting replies

• Saves sent messages into the Sent folder so they appear in PrivateEmail webmail

Why this exists

Namecheap PrivateEmail does not provide a public API for mailbox automation in the same way many SaaS products do. The supported integration path is standard email protocols. This server gives Claude Code a clean MCP interface on top of those protocols.

Installation for Claude Code

Fastest install from GitHub

After this repository is pushed, add it directly to Claude Code with one command:

claude mcp add --scope user \
  --env PRIVATEEMAIL_ADDRESS="you@yourdomain.com" \
  --env PRIVATEEMAIL_PASSWORD="your-password" \
  --env PRIVATEEMAIL_DISPLAY_NAME="Your Name" \
  privateemail \
  -- uvx --from git+https://github.com/ciphersolutions-dev/private-email-mcp privateemail-mcp

Notes:

• --scope user installs it once for all your projects. Use --scope project if you want a repo-local setup instead.

• Everything after the -- separator is the command Claude Code runs.

• uvx --from git+... privateemail-mcp installs and launches the server directly from GitHub.

Install from a local clone

git clone https://github.com/ciphersolutions-dev/private-email-mcp.git
cd private-email-mcp
uv sync

claude mcp add --scope user \
  --env PRIVATEEMAIL_ADDRESS="you@yourdomain.com" \
  --env PRIVATEEMAIL_PASSWORD="your-password" \
  --env PRIVATEEMAIL_DISPLAY_NAME="Your Name" \
  privateemail \
  -- uv run --directory "$PWD" privateemail-mcp

Helper install script

You can also use the included helper script after cloning the repo:

./scripts/install-claude-code.sh "you@yourdomain.com" "your-password" "Your Name"

By default it registers the server at user scope. Pass a fourth argument of project to make it project scoped:

./scripts/install-claude-code.sh "you@yourdomain.com" "your-password" "Your Name" project

Configuration

Environment variables:

• PRIVATEEMAIL_ADDRESS - full mailbox address

• PRIVATEEMAIL_PASSWORD - mailbox password

• PRIVATEEMAIL_DISPLAY_NAME - display name used for outbound mail

• PRIVATEEMAIL_IMAP_HOST - defaults to mail.privateemail.com

• PRIVATEEMAIL_IMAP_PORT - defaults to 993

• PRIVATEEMAIL_SMTP_HOST - defaults to mail.privateemail.com

• PRIVATEEMAIL_SMTP_PORT - defaults to 465

• PRIVATEEMAIL_MAX_ATTACHMENT_BYTES - maximum attachment payload returned by the server

Example .env:

PRIVATEEMAIL_ADDRESS=you@yourdomain.com
PRIVATEEMAIL_PASSWORD=your-password
PRIVATEEMAIL_IMAP_HOST=mail.privateemail.com
PRIVATEEMAIL_IMAP_PORT=993
PRIVATEEMAIL_SMTP_HOST=mail.privateemail.com
PRIVATEEMAIL_SMTP_PORT=465
PRIVATEEMAIL_DISPLAY_NAME=Your Name
PRIVATEEMAIL_MAX_ATTACHMENT_BYTES=10485760

Usage in Claude Code

Useful Claude Code commands:

• claude mcp list

• claude mcp get privateemail

• claude mcp remove privateemail

Typical flows:

• Read inbox: use privateemail://inbox/recent or call list_emails

• Review unread mail: use triage_unread

• Draft a reply: use draft_reply

• Send a message now: use send_email

• Reply in-thread: use reply_email

• Save a draft: use save_draft

Development

uv sync
uv run pytest tests/ -q

Run locally:

uv run privateemail-mcp

PrivateEmail behavior note

SMTP delivery alone does not create a copy in the Sent folder. This server explicitly appends a copy to Sent after a successful send so the message shows up in PrivateEmail webmail.

Security

• Keep your mailbox password in environment variables, not source control

• .env is ignored by git

• Consider using a dedicated mailbox or app-specific credential if your setup allows it
