to:name@example.com          # To specific recipient
subject:keyword              # Subject contains
has:attachment               # Has attachments

Common Workflows

1. Daily Inbox Triage (Recommended 15-30 min/day)

Goal: Process inbox to zero efficiently

Steps:

# 1. Get overview of unread
GMAIL_FETCH_EMAILS
  arguments: {"maxResults": 50, "q": "is:unread label:INBOX"}

# 2. Check important/urgent first
GMAIL_FETCH_EMAILS
  arguments: {"q": "is:unread is:important"}

# 3. Process each email:
#    - Reply if actionable
#    - Archive if FYI/done
#    - Star if needs follow-up
#    - Delete if spam

# 4. Mark processed as read + archive
GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["msg_id_1", "msg_id_2"],
    "removeLabelIds": ["UNREAD", "INBOX"]
  }

The STAR Rule:

• Span 2 minutes? → Do it now


• Trash it? → Delete spam/irrelevant


• Archive it? → Done, no action needed


• Reply/Respond → Draft if complex

2. Achieving Inbox Zero

Process every email with a decision:

Archive	FYI/processed	Remove INBOX label
Reply	Needs response	GMAIL_REPLY_TO_EMAIL
Defer	Complex response	GMAIL_CREATE_DRAFT
Star	Follow up later	Add STARRED label

Batch archive processed emails:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", "id3"],
    "removeLabelIds": ["INBOX"]
  }

  arguments: {
    "ids": ["id1", "id2", "id3"],
    "removeLabelIds": ["INBOX"]
  }

Star for follow-up:

GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2"],
    "addLabelIds": ["STARRED"]
  }

6. Label Organization

Best Practices

Productivity

Process in batches: Dedicated time blocks, not continuous checking

2-minute rule: If reply takes <2 min, do it now

Touch once: Make a decision on each email when you read it

Unsubscribe aggressively: Reduce incoming noise

Use filters: Auto-label/archive predictable emails

Safety

Always confirm before bulk deletes

Use maxResults to limit scope

Archive instead of delete when uncertain

Check trash before permanent deletion

Organization

Keep labels simple (max 2 levels deep)

Search is often better than complex folders

Star for follow-up, archive everything else

Weekly review of starred items

  }

"Archive all newsletters"

# First find them
GMAIL_FETCH_EMAILS
  arguments: {"q": "from:newsletter OR from:noreply label:INBOX", "maxResults": 50}

# Then archive batch
GMAIL_BATCH_MODIFY_MESSAGES
  arguments: {
    "ids": ["id1", "id2", ...],
    "removeLabelIds": ["INBOX"]

Integration Notes

Rube MCP Connection

• Tools accessed via Rube API at app.rubeai.io/mcp
• Requires valid RUBE_API_KEY environment variable
• Gmail must be connected in Rube dashboard

Tool Call Format

# Via curl
curl -s "" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $RUBE_API_KEY" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"GMAIL_FETCH_EMAILS","arguments":{"maxResults":10,"q":"is:unread"}}}'

Error Handling

Remember

Email is a tool, not a job. The goal is efficient communication, not perfect organization. Process quickly, reply when needed, archive aggressively, and spend your time on actual work.
