Jmap Email

JMAP Email Access

Access JMAP email servers (FastMail, Cyrus IMAP, Stalwart) using pre-built scripts.

Prerequisites

Environment variables must be set before launching Claude Code:

• JMAP_SESSION_URL - JMAP server session URL
• JMAP_BEARER_TOKEN - Authentication bearer token
• JMAP_ACCOUNT_ID - Account ID (optional, auto-detected)

Available Scripts

Choose the right script:

• Browse recent emails? → Use list-emails.ts (supports --unread, --flagged, --mailbox, --from, --limit filters)
• Search by sender? → Use list-emails.ts --from "sender@example.com"
• Search for multiple keywords? → Use search-keywords.ts keyword1 keyword2 ...
• Get full email content? → Use get-email.ts with email ID
• View folder structure? → Use list-mailboxes.ts
• Move emails by ID? → Use move-by-ids.ts --mailbox <name> <id1> <id2> ...
• Delete emails? → Use delete-emails.ts <id1> <id2> ...

All scripts support --help for detailed usage.

Common Tasks

Browse unread emails

node scripts/list-emails.ts --unread
node scripts/list-emails.ts --unread --limit 50

Find emails from specific sender

node scripts/list-emails.ts --from "sender@example.com"
node scripts/list-emails.ts --from "sender@example.com" --unread

Search for receipts or specific content

node scripts/search-keywords.ts "invoice" "receipt" "order confirmation"
node scripts/search-keywords.ts --mailbox "Archive" --limit 10 "meeting" "agenda"

Note: Search shows previews only. For full email content, use get-email.ts with the email ID.

Get full email content

node scripts/get-email.ts <email-id>

Organize emails (classification workflow)

1. Search for candidates: search-keywords.ts "keyword1" "keyword2"
2. Review previews and identify relevant email IDs
3. (Optional) View full content: get-email.ts <email-id>
4. Move to target mailbox: move-by-ids.ts --mailbox @MailboxName id1 id2 id3

Interactive email triage

Workflow for processing new emails with learning:

1. Fetch recent emails:

   • Use list-emails.ts --limit 20 to get batch (optionally add --unread or --mailbox "Inbox")
   • Review subject, sender, and preview

2. Present classification options:

   • Use AskUserQuestion with multiSelect for each email
   • Options should be target mailboxes (Inbox, Archive, @Reference, etc.)
   • Allow user to select destination for each email

3. Execute moves:

   • Group emails by target mailbox
   • Use move-by-ids.ts --mailbox <name> <id1> <id2> ... for each group

4. Save routing patterns to memory:

   • Note sender domains and subjects that map to specific mailboxes
   • Record user's classification decisions (e.g., "newsletters from X → Archive")
   • Reference these patterns in future triage sessions
   • Suggest automatic routing rules based on observed patterns

Benefits:

• Process inbox in batches with interactive guidance
• Build up routing knowledge over time
• Suggest classifications based on past decisions
• Gradually automate common routing patterns
