One URL. No secret to paste.
ChatGPT connects with OAuth. You give it the server URL, sign in to CommSync, and approve the app on one screen. You can disconnect it at any time.
- Step 1
Open the CommSync plugin in ChatGPT. Open in ChatGPT on the Connect AI apps page opens the same page.
- Step 2
Add the plugin. ChatGPT opens CommSync.
- Step 3
Sign in, choose your lines, and allow access.
No developer mode and no custom connector. The plugin page does the setup.
Everything you can do in CommSync, ChatGPT can do too.
The MCP server exposes the same services the CommSync app uses, from a search to building a whole agent. ChatGPT picks the tool; CommSync keeps it inside your lines.
223 tools in 27 sections. The same ones the CommSync app uses.

- Summarize every text from the Hartley Ave group this week.
- Which bills are due before Friday?
- Reply to the lead who asked about kitchen estimates, and offer two times.
- How many conversations did my agents handle today?
- Read and search
Threads, contacts, files, and smart cards, with search by meaning over mail, texts, and scanned attachments.
- Send as you
Replies and new texts or email from your lines. A send to an outside person is marked as such, so ChatGPT asks before it sends.
- Build an agent
96 tools cover agents: draft one from a description, give it knowledge and tools, write tests, read its analysis, and approve its drafts.
No developer mode. One plugin page.
The CommSync plugin for ChatGPT has been live since October 2026. Open the plugin page, add it, sign in. There is no custom connector to configure.
- Web, desktop, phone
The plugin works in ChatGPT on the web, on the desktop, and on mobile, with one sign-in for all three.
- Codex too
The same plugin page serves Codex, so a team on both adds CommSync once and gets it in the chat and in the terminal.
- A send waits for you
send_sms and send_email are marked as sends, so ChatGPT shows you the message and waits for a yes before anything leaves.
You choose the lines. CommSync holds the rest back.
On the consent screen you pick what ChatGPT can reach. A scoped app sees only the threads on its lines, and CommSync refuses a send from any other line.
- No password
ChatGPT never receives your password or an API key. It gets a token that lasts an hour and renews in the background.
- Named apps
ChatGPT is a proven brand on its own address, so the consent screen shows the green Verified pill.
- Disconnect
Disconnect in Settings → Connect AI apps. The app stops at once, on every device. Change its lines without a new sign-in.
No account yet? Start from ChatGPT.
When ChatGPT opens CommSync and you have no account, one visit does all of it. CommSync keeps the request open for up to 2 hours while you set up.
- Step 1

- Step 2
Enter the 6-digit code from the email, or use the button in it.
- Step 3
Choose Just me or a team, then connect an email address or a phone number. The 7-day trial starts, with no card.
- Step 4
CommSync takes you back to the consent screen. Select Allow access, and you are back in ChatGPT.
What ChatGPT gets, and what it does not.

- Can it send messages?
- Yes, from the lines you allow. Tools such as
send_smsandsend_emailare marked as sends, so ChatGPT asks before it sends to an outside person. - What is the server URL?
