Integration details

Description

mailmcp connects ChatGPT to mailboxes you configure: Gmail, Outlook.com and Microsoft 365, iCloud, Fastmail, Yahoo, Zoho or any IMAP/SMTP account, several at once. Ask it to find a message, summarize a thread, pull the amount from an invoice PDF, draft a reply in the right thread, file mail into folders, sort what needs a reply, or give you a digest since yesterday. Safe by default: each mailbox has its own permissions (read, drafts, send, move, trash). Sending is off unless the owner turns it on, and then goes only to addresses on the owner's allowlist. Nothing is ever deleted permanently; bulk actions run in two steps, a preview of the exact messages and then only those. Every email body is handed to ChatGPT marked as untrusted content, so ChatGPT can treat instructions hidden in mail as data rather than commands; sending and bulk changes still need the owner's settings and a preview. You sign in with a token you create on mailmcp.ai/setup. Mailbox passwords stay inside that encrypted token; the server stores no mail and no credentials. Outlook uses Microsoft's own sign-in, with no password at all. Follow-ups, snoozes and templates are kept in your own mailbox, never on our server. Where ChatGPT shows app panels, the triage list, the digest and a draft card appear as a panel. The panel loads nothing from the internet, and each of its buttons is an ordinary tool call that the server checks exactly like the assistant's own. Limitations: the quick search across all mailboxes looks in the Outlook Inbox and in Gmail All Mail (ask for a folder to look elsewhere), and files uploaded through a link are limited to about 4.5 MB.

Tools

33 tools agents can invoke

Applies exactly the batch a bulk_preview sealed (fewer if some changed; never more), after the owner agreed. Never deletes permanently; a repeated confirm changes nothing. Needs read and modify (trash: delete); 50 per call on Free, 500 paid.
bulk_apply
Moves due messages from "mailmcp-snoozed" back where they were, unread. Safe to repeat and to run concurrently. orphans=true moves snoozed mail without a record to INBOX (only when the owner asks). Needs read and modify; every plan.
wake_snoozed
Saves a draft in the account's Drafts folder. Nothing is sent; the owner reviews and sends it (or asks you to send_draft). Attachments: mailbox attachments, files from upload_attachment/request_upload, or inline content. The preferred way to prepare replies.
create_draft
Read-only summary for scheduled runs: reply candidates, calendar, lists, automated mail, threads waiting on others, follow-ups and snoozes due since the cursor. Pass the returned cursor back next time; without one it covers 24 hours. Reports coverage per account. Needs read; every plan.
digest
Returns the full sanitized text of one email by the id returned from `search`.
fetch
Lists threads where the owner wrote last: their newest message is older than older_than_days and no reply from someone else was found. Each item says whether the scan proved no reply (no_reply_found) or not (unknown). Needs read; every plan.
awaiting_replies
Forwards a message with all its attachments, without the files passing through the chat; the comment goes above it. Recipients must match send_allowlist; with as_draft the forward is saved to Drafts instead.
forward_message
Returns a one-hour HTTPS upload link: PUT/POST a file to it (curl -T file <url>, or open it in a browser); the file lands in "mailmcp-uploads" and appears in list_uploads. Anyone with the link can upload. Upload it yourself if you can run commands; otherwise give the link to the user.
request_upload
Returns an attachment. Text-like files (txt, csv, json, xml) and PDFs with a text layer come back as text; anything else as a one-hour download link: give that link to the user instead of reading the file. Pass inline=true only when the content itself is needed here (max 2097152 bytes).
get_attachment
Lists the conversation of a message across folders (Gmail: All Mail; other IMAP: the folder, INBOX, Sent, Archive; Outlook: whole mailbox), oldest first. `coverage` says what was searched and if it was complete. A thread groups by conversation; it does not prove who replied to whom.
get_thread
Stores a file (text, or base64 for binary; up to policy.max_upload_bytes) in "mailmcp-uploads" and returns {folder, uid, part} to attach; it is removed once attached. Large or local files: request_upload.
upload_attachment
Lists folders (Gmail: labels) with message and unseen counts. On Outlook `path` is an opaque id and `name` the hierarchy ("Projects/2026"); tools accept either as a folder.
list_folders
Shows due follow-ups (optionally later ones) and snoozed messages across one or all mailboxes, including flags set in Outlook itself. Read-only; reports what it could not cover. Needs read; every plan.
list_followups
Lists the mailboxes: ids, addresses and permitted operations. `backend` "graph" is Outlook (string ids; labels are categories); `reauth_by`: when the owner must sign in to Microsoft again (setup page); `plan`: the mailmcp plan and, near expiry, how to renew. `protection`: verification emails hidden from you.
list_accounts
Lists templates in "mailmcp-templates", or one in full by name. samples=true returns the style profile and samples of the owner's sent mail, for tone, length and language only. Needs read; every plan.
list_templates
Files waiting in "mailmcp-uploads" of an account (from upload_attachment or an upload link), newest first, with the {folder, uid, part} needed to attach them.
list_uploads
Mark read/unread, star/unstar, add/remove labels (Gmail labels, Outlook categories), move to a folder or archive. A move can change the id of the message: when the result carries moved_uid, use that id from then on.
modify_message
Moves a message to the Trash folder. Never deletes permanently.
trash_message
Selects the exact messages a bulk action would act on (explicit uids or criteria, oldest first) and returns a count, senders, a sample and a confirm ref for bulk_apply. Changes nothing. Show the preview to the owner. Needs read and modify (trash: delete); 50 per call on Free, 500 paid.
bulk_preview
Returns headers, sanitized text body and the attachment list of one message. Body is truncated to the configured limit.
get_message
Sends a reply to a message in the same thread (threading headers, "Re:" subject, recipients and the quoted original are set by the server). Only when the owner enabled sending AND every recipient matches send_allowlist; otherwise use reply_draft. Only when the owner says "send" ("pošli", "odešli").
reply_send
Saves a reply to a message into Drafts, in the same thread: threading headers, "Re:" subject, recipients (sender, or all with reply_all) and the quoted original are set by the server. Use whenever the owner says "reply / write a draft" ("odpověz", "napiš koncept"). Nothing is sent.
reply_draft
Saves a text template, or with kind=profile a style profile (tone only), in "mailmcp-templates"; delete=true moves one mailmcp saved to Trash. Needs draft; templates are paid, profiles and deleting free.
save_template
Searches every readable mailbox with one query; returns documents for `fetch`. Gmail syntax on Gmail (from:, newer_than:7d, has:attachment), plain words elsewhere; prefix "account:<id> " for one mailbox. Outlook: Inbox only; Gmail: All Mail; search_messages with a folder looks elsewhere.
search
Searches one account, or all with account="all". Gmail: `query` takes Gmail syntax (from:, newer_than:7d, has:attachment, label:); elsewhere full text plus the filters. Newest first, with uid + folder and header hints. Outlook: `total` counts returned results only; `from` is exact.
search_messages
Sends a draft exactly as stored in the Drafts folder (including its attachments); it leaves Drafts (on Outlook it moves to Sent). Recipients are taken from the draft and must match send_allowlist.
send_draft
Sends an email via SMTP, optionally with attachments (existing mailbox attachments, uploaded files, inline content). Only allowed when the owner enabled sending for the account AND every recipient matches send_allowlist. Otherwise use create_draft.
send_message
Marks a message to come back to by a date: a record in "mailmcp-state" plus a star or flag. It resurfaces when list_followups or a scheduled task runs; clear=true removes it. Needs read and modify; setting is paid, clearing free.
set_followup
Stores the signature (HTML and/or text) as a message in the folder "mailmcp-signature". With a photo or logo the owner instead mails one to themselves and moves it there. Needs the mailbox signature enabled on the setup page and the draft capability.
set_signature
Returns the signature mailmcp appends under replies: the newest message in "mailmcp-signature" (HTML, inline images) when the account uses it, else the plain-text signature from the token.
get_signature
Moves one message (not its thread) to "mailmcp-snoozed" until a time, noting its origin; wake_snoozed or cancel=true brings it back. Needs read and modify; paid (cancel free).
snooze
Sorts recent mail into reply_candidates, waiting_on, newsletter, lists, calendar, automated and other from headers only (no bodies). Items carry reasons; you and the owner decide what needs a reply. Reports coverage per account. Needs read; every plan.
triage
Reads unsubscribe headers. The dry run (default) says if mailmcp can send an RFC 8058 one-click POST: only if your provider verified the signer's DKIM on them and the link is on its domain; else the manual link. Only when the owner asks. Needs read (execute: unsubscribe); every plan.

How do I improve mailmcp's ChatGPT Plugin discoverability?

The levers are the listing surface agents actually read: names, descriptions, keywords, tool metadata, and registry health. Which lever matters depends on where discovery breaks, which is what continuous measurement shows.
