Common questions
Is Hub safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 42 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Vexa, emailmd, MCP WhatsApp Cloud

Hub — a multi-account Google connector for Claude
A remote MCP server that gives Claude access to several Google accounts at once — Gmail, Calendar, Drive, Contacts and Tasks. Claude's built-in Google connectors each hold exactly one account; connecting a second replaces the first. This holds as many as you link, and every search tool fans out across all of them in a single call.
AOL mailboxes link too. They are reached over IMAP and SMTP with an app password, sit behind the same mail tools, and are searched together with Gmail — see AOL mailboxes.
Run it yourself and it holds your Google tokens in your own database, encrypted, and talks to Google directly — nothing passes through a third party. Or try the hosted one first.
Node and Postgres, six tables. Dependencies are Express, pg and jsonwebtoken, plus imapflow, mailparser and nodemailer for AOL — IMAP, MIME and SMTP are protocols, not parsing jobs, and each library is the maintained standard for its one. Document text extraction — PDF, Word, Excel, PowerPoint, OpenDocument — uses only Node's standard library.
Status: running in production against real mailboxes, with 564 automated checks. Built for one person's needs and published because the one-account limit is not unique to them. Treat it as working software with a small user base, not as a hardened product.
Try the hosted one
A copy runs at hub.grounders.app. It is in testing, and free while it is.
- In Claude: Settings → Connectors → Add custom connector, with the URL
https://hub.grounders.app/mcp. ChatGPT, Cursor and other MCP clients take the same URL as a remote MCP server. - Sign in with Google once when asked.
- Link each account at hub.grounders.app/gmail/connect.
Google's review of the app is still in progress, so you will see an "unverified app" screen the first time.
Quick start
git clone https://github.com/ItsBreeze/google-multi-account-mcp.gitcd google-multi-account-mcp npm install cp .env.example .env # fill it in — see Setup below npm run migrate # creates the six tables npm start
Then deploy it somewhere with a public HTTPS URL (Railway, Fly, Render, a VPS — anything that runs Node and reaches Postgres) and follow Setup.
Endpoints
| Method | Path | Description |

| GET | /mcp/oauth/authorize | Consent screen — operator password |
| POST | /mcp/oauth/token | Token + refresh grants |
| POST | /mcp/oauth/register | RFC 7591 dynamic client registration |
| GET | /.well-known/oauth-protected-resource | RFC 9728 discovery |
| GET | /.well-known/oauth-authorization-server | RFC 8414 discovery |

Tools (59)
Every tool takes an optional account. On a search, omitting it fans the call out across every linked account and merges the results — the thing no single-account connector can do. On a write it names the one account to act on, so "create this event" is never ambiguous about whose calendar it lands in.
Mail — Gmail and AOL (23)
| Area | Tools | Notes |
|---|---|---|
| Accounts | list_accounts | Which accounts are linked, with token health |
| Search | search_messages, search_threads | Gmail query syntax, merged and date-sorted across accounts. search_threads returns one row per conversation — subject, every participant, message and unread counts, last activity — for "where does my thread with X stand" without pulling bodies |
| Read | get_message, get_thread, get_attachment | Bodies flattened to text and capped at 60 KB; attachment metadata included. `get_attachment` extracts text from PDF, Word, Excel, PowerPoint and OpenDocument attachments, so an emailed contract or invoice is readable directly; anything else comes back base64 (2 MB cap) |
| Send | send_message, reply_to_message, forward_message | Replies thread via In-Reply-To/References; forwards carry attachments (10 MB cap, skipped ones named); optional from + fromName send as a verified Gmail send-as alias |
| Drafts | create_draft, list_drafts, get_draft, update_draft, send_draft, delete_draft | create_draft with reply_to_message_id drafts an in-thread reply for review — the safe path for AI-written mail; create_draft and send_draft also take from/fromName (send_draft rewrites the draft's From first, Gmail only) |
| Labels | modify_labels, list_labels, create_label, update_label, delete_label | modify_labels takes message_id or thread_id; removing INBOX archives |
| Trash & spam | trash_message, untrash_message, mark_spam | All take message_id or thread_id; trash is recoverable for 30 days; mark_spam with unmark: true restores |
Calendar (9)
| Area | Tools | Notes |
|---|---|---|
| Read | list_calendars, list_events, search_events, get_event | list_events merges every linked calendar into one timeline, defaulting to the next 7 days; recurring series are expanded into actual occurrences, so a weekly standup appears on each day it happens |
| Write | create_event, update_event, delete_event | Times are ISO 8601; a bare YYYY-MM-DD means all-day. update_event patches — unmentioned fields keep their value. Attendees are not emailed unless send_updates says so |
| Repeats | create_event, update_event, delete_event | repeat: "weekly" (with repeat_count or repeat_until) covers the ordinary cases; recurrence takes full RFC 5545 rules. On a repeating event, scope chooses one occurrence or the whole series — see below |
| RSVP | respond_to_event | accepted / declined / tentative, as the account that was invited; notifies the organiser by default |
| Scheduling | suggest_time | Free slots across every linked calendar at once — busy anywhere means busy. Returns whole gaps rather than chopping a 3-hour opening into six half-hour slots |
Drive (15)
| Area | Tools | Notes |
|---|---|---|
| Find | search_files, list_recent_files, get_file_metadata, list_shared_drives | Text search over names and contents, with optional raw Drive query syntax in filter. Covers My Drive and every shared drive at once; drive_id narrows to one. Trashed files excluded unless you ask for them |
| Read | read_file_content, download_file_content | Docs, Sheets and Slides exported (Sheets as CSV); PDF, Word, Excel, PowerPoint and OpenDocument extracted to text; ocr: true routes scans and images through Google's own conversion; include_comments returns the comment threads. download_file_content takes export_as — turn a Doc into a PDF or docx, a Sheet into xlsx. Text caps at 60 KB, binaries at 2 MB base64 |
| Write | create_file, update_file, copy_file | Text via content, binary via content_base64. convert_to makes Drive convert the upload into an editable Doc, Sheet or Slides — or a folder. update_file renames, moves and describes; overwriting contents additionally needs replace_content: true. On a file you do not own it edits a private copy — see below |
| Comment | comment_on_file | Leave a comment on a draft, or reply to a thread — the review path that changes nothing in the document |
| Sharing | get_file_permissions, share_file, unshare_file | Shares with one named person at reader/commenter/writer. Domain-wide and public-link sharing are off unless DRIVE_ALLOW_PUBLIC_SHARING=true, and then still need confirm_public. `unshare_file` withdraws access — by person, by domain, or by removing the public link |
| Remove | trash_file, untrash_file | Trash and restore, within the 30-day window — see the scope note below |
Contacts (2) and Tasks (5)
| Area | Tools | Notes |
|---|---|---|
| Contacts | search_contacts, list_contacts | Read-only. Searches saved contacts and people the account has corresponded with, so "email Ann" resolves to an address instead of a guess |
| Tasks | list_task_lists, list_tasks, create_task, update_task, delete_task | list_id defaults to the account's first list. update_task with completed: true ticks a task off; false reopens it. Google Tasks has no trash, so delete_task is permanent |
AI agents (5)
AIs talk to each other through Hub instead of by email. Every message has a thread, a hop count and a read time, so nothing is lost to subject matching and a sender can see whether it was read.
| Area | Tools | Notes |
|---|---|---|
| Talk | ai_send, ai_inbox, ai_thread | ai_send with thread answers in place and to defaults to the other side. ai_inbox with wait_seconds (up to 50) holds until a reply arrives. Threads stop at hop 10 |
| Agents | ai_agents, ai_set_agent | An agent can be woken by email (one JSON object from a linked mailbox, subject template like Claude -> Lute (hop {hop})) or by webhook (POST {"text"}, headers stored encrypted). A failed wake keeps the message unread and tells the sender |
An agent without MCP needs no account: each wake carries a signed reply_url (30 days, one owner, one agent). POST {"text":"..."} to it to answer, GET it to read the thread, or POST {"new_thread":true,"to":"claude","text":"..."} to start a new conversation.
AOL mailboxes
Link one at /gmail/aol with the address and an app password generated at AOL Account Security — AOL has no OAuth for third-party mail clients outside an approved partner list, so this is the only door. The password is signed in to IMAP before it is stored (one app password covers IMAP and SMTP), so a typo is reported on the link page, not on Claude's first tool call. It is stored AES-256-GCM encrypted under TOKEN_ENC_KEY, like the Google tokens. Hosts come from a preset in code (imap_providers.js), never from the request.
Sending goes through a relay where SMTP is blocked. Railway blocks outbound SMTP below its Pro plan, so hub.grounders.app hands each AOL submission over HTTPS to a Cloudflare Worker (smtp-relay/) that speaks SMTP to smtp.aol.com:465. The Worker stores and logs nothing and reaches only preset hosts. It is used when SMTP_RELAY_URL and SMTP_RELAY_TOKEN are set; without them the server talks SMTP directly, as a self-hosted copy that can reach port 465 should. Gmail sending is unaffected — it goes through Google's API.
The 23 mail tools work on an AOL mailbox unchanged, and a search with no account covers Gmail and AOL in one merged, date-sorted result. What differs is IMAP itself, and the tools say so rather than pretend:
| Gmail | AOL over IMAP |
|---|---|
| Labels, several per message | Folders, one per message. UNREAD/STARRED are flags; INBOX, SPAM, TRASH and folder names move the message. A change that would need two folders is refused; IMPORTANT and categories do not exist |
| Ids are permanent | An id is folder + UID, so a move gives the message a new id — every moving call returns it as new_message_id. An id from a folder the server renumbered is refused as stale, never resolved to a different message |
| Gmail query syntax | Translated to IMAP SEARCH: from: to: cc: bcc: subject: is:unread/read/starred has:attachment newer_than: older_than: after: before: in: label: larger: smaller:, phrases, OR, -, parentheses. Anything el
