What ChatGPT can do

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.

Things people ask ChatGPT
  • 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.

Made for ChatGPT

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.

Your lines only

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.

Start inside ChatGPT

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.

  1. Step 1

    Select Create an account, and enter your name, email address, and password.

  2. Step 2

    Enter the 6-digit code from the email, or use the button in it.

  3. 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.

  4. Step 4

    CommSync takes you back to the consent screen. Select Allow access, and you are back in ChatGPT.

Questions

What ChatGPT gets, and what it does not.

Short answers for ChatGPT users.

Does ChatGPT get my password?
No. You sign in on the CommSync page. ChatGPT gets a token for your lines, CommSync stores only a hash of it, and a token that leaks is signed out when an old copy appears.
Can it send messages?
Yes, from the lines you allow. Tools such as send_sms and send_email are marked as sends, so ChatGPT asks before it sends to an outside person.
What is the server URL?
https://server.commsync.ai/api/mcp, for every app. Settings → Connect AI apps shows it with a copy button and a guide for each app.
Where is CommSync listed?
The CommSync plugin for ChatGPT and Codex has been live since 2026-10-09.
