Gmail Tools

Secure Gmail access via IMAP/SMTP with 1Password credential storage. Supports listing, reading, searching, sending, and replying to emails with proper threading and attachments.

When to Use

• Reading and managing Gmail emails
• Sending emails with attachments
• Replying to emails while maintaining thread continuity
• Searching emails using IMAP queries

Prerequisites

1Password Setup

Create a 1Password item with:

• Item name: Any descriptive name (e.g., "Gmail Work Claude", "Gmail Personal")
• username field: Your Gmail address (e.g., user@gmail.com)
• password field: Gmail App Password (NOT your regular password)

Getting a Gmail App Password

1. Go to Google Account Security
2. Enable 2-Factor Authentication if not already enabled
3. Go to "App passwords" (under "2-Step Verification")
4. Generate a new app password for "Mail"
5. Copy the 16-character password to your 1Password item

MCP Server Tools

The plugin provides these MCP tools:

list_emails

List recent emails from an account.

Copyaccount: "Gmail Work Claude"  # 1Password item name
folder: "INBOX"               # Optional, default: INBOX
limit: 10                     # Optional, default: 10

read_email

Read full email content including threading headers.

Copyaccount: "Gmail Work Claude"
email_id: "46"                # From list_emails
folder: "INBOX"               # Optional

send_email

Send a new email with optional attachments.

Copyaccount: "Gmail Work Claude"
to: "recipient@example.com"
subject: "Hello"
body: "Email content here"
cc: "cc@example.com"          # Optional
bcc: "bcc@example.com"        # Optional
attachments: ["/path/to/file.pdf"]  # Optional

reply_email

Reply to an email, maintaining the thread.

Copyaccount: "Gmail Work Claude"
email_id: "46"                # Email to reply to
body: "Thanks for your message!"
attachments: ["/path/to/doc.pdf"]  # Optional
folder: "INBOX"               # Optional

search_emails

Search using IMAP syntax.

Copyaccount: "Gmail Work Claude"
query: "FROM sender@example.com"  # or "SUBJECT hello", "UNSEEN", etc.
folder: "INBOX"               # Optional
limit: 10                     # Optional

Standalone Scripts

For CLI usage without MCP, use scripts in scripts/:

List Emails

Copy./scripts/gmail_list.py "Gmail Work Claude" --limit 20
./scripts/gmail_list.py "Gmail Work Claude" --json  # JSON output

Read Email

Copy./scripts/gmail_read.py "Gmail Work Claude" "46"
./scripts/gmail_read.py "Gmail Work Claude" "46" --json

Reply to Email

Copy# Dry run (preview without sending)
./scripts/gmail_reply.py "Gmail Work Claude" "46" \
  --body "Thanks for your email." \
  --attachment ~/document.pdf \
  --dry-run

# Send reply
./scripts/gmail_reply.py "Gmail Work Claude" "46" \
  --body "Thanks for your email." \
  --attachment ~/document.pdf

Email Threading

When using reply_email, the tool automatically:

1. Extracts the original email's Message-ID and References headers
2. Sets In-Reply-To to the original Message-ID
3. Builds proper References header chain
4. Adds RE: prefix to subject if not present
5. Sends to the sender's email address

This ensures replies appear in the same thread in all email clients.

Common IMAP Search Queries

Combine with parentheses: (FROM "john" SUBJECT "meeting")

Troubleshooting

"1Password item not found"

Verify the exact item name in 1Password matches what you're using.

"Authentication failed"

• Ensure you're using an App Password, not your regular Gmail password
• Verify 2FA is enabled on your Google account
• Check the App Password hasn't been revoked

"IMAP not enabled"

Enable IMAP in Gmail Settings → Forwarding and POP/IMAP → Enable IMAP
