• imap_test_account

• imap_search_emails

  Note: on some servers a 'flagged' or starred message carries a custom keyword (e.g. an Open-Xchange color label or Apple's $MailFlagBit*) instead of, or in addition to, the \Flagged system flag. After any flagged search, inspect each result's customKeywords field before concluding a message is or is

• imap_get_email

  Read the FULL content of a single email by its UID (body, sender/recipients, date, attachment list, optional raw headers and text-attachment previews). By default the body is returned as clean Markdown in markdownContent and raw HTML is omitted so it never crosses the boundary; set bodyFormat to "ht

• imap_upload_file

  Upload a file to the server for use as an email attachment. Returns a path that can be used with imap_send_email attachments. This allows sending large attachments without hitting context window limits. Max size: 26214400 bytes (configurable via IMAP_MAX_UPLOAD_SIZE). Uploads are auto-deleted after

• imap_download_attachment

  Download a single attachment from an email (folder + uid + attachment filename/contentId, as listed by imap_get_email). Images are returned inline for viewing; PDFs are saved and their text is extracted inline (extractText); other files are saved to the shared downloads directory (or savePath). Use

• imap_mark_as_read

  Mark one or many emails as read. Accepts a single UID or an array — pass an array to flag N messages in one IMAP STORE round-trip (useful when triaging).

• imap_mark_as_unread

  Mark one or many emails as unread. Accepts a single UID or an array — pass an array to flag N messages in one IMAP STORE round-trip.

• imap_flag_email

  Flag an email — sets the IMAP \Flagged system flag (shows as a star in Gmail / a flag in Apple Mail). Use this tool when a user asks to star, flag, or mark a message as important.

• imap_unflag_email

  Unflag an email — removes the IMAP \Flagged system flag (the star in Gmail, the flag in Apple Mail). Note: some servers (e.g. Open-Xchange / Network Solutions) and Apple Mail also write a separate custom keyword such as $cl_N or $MailFlagBit* when a message is flagged in their client. Removing \Flag

• imap_add_keyword

  Set an arbitrary custom (non-system) IMAP keyword/label on an email — e.g. a provider color label like Open-Xchange's $cl_1..$cl_10, Apple Mail's $MailFlagBit0..$MailFlagBit2, or an app tag such as $promotion. Unlike imap_flag_email (which only ever sets the system \Flagged flag), this passes the ke

• imap_remove_keyword

  Remove an arbitrary custom (non-system) IMAP keyword/label from an email — e.g. a provider color label like Open-Xchange's $cl_1..$cl_10, Apple Mail's $MailFlagBit0..$MailFlagBit2, or an app tag such as $promotion. Unlike imap_unflag_email (which only ever clears the system \Flagged flag), this pass

• imap_delete_email

  Delete ONE email by folder + uid (moves to Trash or expunges, server-dependent). Destructive and not easily undone — confirm the user means this specific message. To remove many at once use imap_bulk_delete (known uids) or imap_bulk_delete_by_search (by criteria, supports dryRun). To file an email a

• imap_move_email

  Move an email from one folder to another (e.g., INBOX to Taxes, or INBOX to Archive). Optionally creates the destination folder if it does not exist.

• imap_bulk_delete

  Delete multiple emails at once with chunking and auto-reconnection. Processes deletions in batches to prevent connection timeouts.

• imap_bulk_delete_by_search

  Search for emails matching criteria and delete them all. Useful for cleaning up spam or unwanted emails. At least one concrete criterion (from, to, subject, before, or since) is REQUIRED — a call with no criteria is refused so it can never wipe an entire folder. Supports dryRun to preview matches fi

• imap_get_latest_emails

  Get the most recent emails from a folder, newest first. Use this for "what just came in?" / "show my latest inbox messages" when no search filter is needed. By default returns lightweight headers (uid, from, subject, date); set `includeBody=true` to also return the parsed body in one round-trip inst

• imap_send_email

  Compose and send a NEW email via the account's SMTP server (a copy is saved to Sent unless disabled; account defaultBcc addresses are always BCC'd when configured). Use for fresh outbound messages. To respond to an existing message use imap_reply_to_email (keeps threading); to pass a message on use

• imap_save_draft

  Save an email as a draft in the Drafts folder (no send). Takes the same fields as imap_send_email (including account defaultBcc when configured).

• imap_reply_to_email

  Reply to an existing email identified by folder + uid. Automatically sets the recipient to the original sender, prefixes the subject with "Re:", and preserves threading (In-Reply-To/References). Set replyAll to also include the original To (and Cc as Cc), excluding the account's own address; a Reply

• imap_forward_email

  Forward an existing email (folder + uid) to new recipients, quoting the original message and headers. Optionally include the original attachments. Use when the user wants to pass an existing message on to someone else; use imap_reply_to_email instead to respond to the sender. Account defaultBcc addr

• imap_find_thread_messages

  Find messages in `searchFolder` that belong to the same conversation threads as messages already in `sourceFolder`. Useful for catching replies that arrived after a thread was sorted. Works on any IMAP server (uses RFC 3501 HEADER search on In-Reply-To and References). Set `includeBody=true` to also

• imap_find_email_by_message_id

  Locate an email by its RFC822 Message-ID across folders and return its current { folder, uid } plus basic envelope. Robust to the message having been moved or archived (IMAP UIDs are folder-relative). Pass the returned folder + uid to imap_reply_to_email or imap_get_email. Without `folders`, searche

• imap_list_folders

  List all folders/mailboxes for an account (names, hierarchy delimiter, attributes, RFC 6154 special-use role). Use this first to discover exact folder names before searching, moving, or creating subfolders — folder naming varies by provider (e.g. "Archive" vs "[Gmail]/All Mail" vs "INBOX.Archive").

• imap_folder_status

  Get status information about a folder

• imap_create_folder

  Create a new IMAP folder/mailbox. Most servers also create any missing parent folders (e.g. creating "Archives/2026/2026-05" auto-creates "Archives" and "Archives/2026"). Returns success even if the folder already exists.

• imap_get_unread_count

  Count unread (unseen) emails per folder, plus a total. Use for "how many unread do I have?" overviews. Defaults to all folders; pass a folders list to limit scope and speed it up.

• imap_check_spam

  Check emails in a folder for spam. Combines sender-domain checks (known spam/disposable domains, suspicious patterns) with deterministic raw-header analysis: bulk-mailer X-Mailer/User-Agent signatures, Precedence: bulk, DMARC/SPF/DKIM failures in Authentication-Results, and List-Unsubscribe / Reply-

• imap_delete_spam

  Find and delete emails from known spam/disposable email domains.

• imap_domain_stats

  Get statistics about sender domains in a folder. Useful for identifying bulk senders or spam patterns.

• imap_add_spam_domain

  Add a domain to the custom spam list. Emails from this domain will be flagged as spam.

• imap_remove_spam_domain

  Remove a domain from the custom spam list.

• imap_add_whitelist_domain

• imap_list_spam_domains

  List all known spam domains (built-in and custom).

• imap_delete_by_domain
