# Gmail

Lightweight Gmail integration with standalone OAuth authentication. No MCP server required.

> **⚠️ Requires Google Workspace account.** Personal Gmail accounts are not supported.

## First-Time Setup

Authenticate with Google (opens browser):
```bash
python scripts/auth.py login
```

Check authentication status:
```bash
python scripts/auth.py status
```

Logout when needed:
```bash
python scripts/auth.py logout
```

## Commands

All operations via `scripts/gmail.py`. Auto-authenticates on first use if not logged in.

### Search Emails

```bash
# Search with Gmail query syntax
python scripts/gmail.py search "from:[email protected] is:unread"

# Search recent emails (no query returns all)
python scripts/gmail.py search --limit 20

# Filter by label
python scripts/gmail.py search --label INBOX --limit 10

# Include spam and trash
python scripts/gmail.py search "subject:important" --include-spam-trash
```

### Read Email Content

```bash
# Get full message content
python scripts/gmail.py get MESSAGE_ID

# Get just metadata (headers)
python scripts/gmail.py get MESSAGE_ID --format metadata

# Get minimal response (IDs only)
python scripts/gmail.py get MESSAGE_ID --format minimal
```

### Send Emails

```bash
# Send a simple email
python scripts/gmail.py send --to "[email protected]" --subject "Hello" --body "Message body"

# Send with CC and BCC

## Gmail Query Syntax

Gmail supports powerful search operators:

| Query | Description |
|-------|-------------|
| `from:[email protected]` | Emails from a specific sender |
| `to:[email protected]` | Emails to a specific recipient |
| `subject:meeting` | Emails with "meeting" in subject |
| `is:unread` | Unread emails |
| `is:starred` | Starred emails |
| `is:important` | Important emails |
| `has:attachment` | Emails with attachments |
| `after:2024/01/01` | Emails after a date |
| `before:2024/12/31` | Emails before a date |
| `newer_than:7d` | Emails from last 7 days |
| `older_than:1m` | Emails older than 1 month |
| `label:work` | Emails with a specific label |
| `in:inbox` | Emails in inbox |
| `in:sent` | Sent emails |
| `in:trash` | Trashed emails |

Combine with AND (space), OR, or - (NOT):
```bash
python scripts/gmail.py search "from:[email protected] is:unread newer_than:1d"
python scripts/gmail.py search "subject:urgent OR subject:important"
python scripts/gmail.py search "from:[email protected] -is:starred"
```
