Connect AI apps
Use your CommSync inbox from Claude, ChatGPT, Codex, Cursor, VS Code, and any MCP app. Paste one URL, sign in, and choose the lines the app can use.
CommSync has its own MCP server. An AI app that speaks the Model Context Protocol can read your conversations, find contacts, and send SMS and email for you. Examples are Claude, ChatGPT, Codex, Cursor, and VS Code.
You connect an app with OAuth. You paste one URL into the app, sign in to CommSync, and approve the app on one screen. You do not copy a secret, and you can disconnect the app at any time.
Where to start
Open Settings → Connect AI apps in CommSync. The page shows your server URL and a short guide for each app.
Your server URL
Every app uses the same URL: the /api/mcp route on your CommSync API origin.
For CommSync cloud, that is:
https://server.commsync.ai/api/mcpSettings → Connect AI apps shows the URL for your workspace, with a copy button.
Connect an app
Works in claude.ai, Claude Desktop, and the Claude mobile apps.
- In Claude, open Settings → Connectors.
- Choose Add custom connector. Name it CommSync and paste your server URL.
- Select Connect. Claude opens CommSync. Sign in and allow access.
On Claude Team and Enterprise, an owner adds the connector one time. Each person then connects their own CommSync account.
The consent screen
Before an app gets access, CommSync shows you one screen. Read it before you select Allow access.
| On the screen | What it tells you |
|---|---|
| The app | The name of the app, and the address where CommSync sends you back. |
| Verified | A green pill. It appears only when CommSync can prove the app, for example Claude on claude.ai. |
| App on this device | A desktop app such as Cursor, Codex, or Claude Code. CommSync cannot verify its name. Continue only if you just added CommSync to that app. |
| Your account | The CommSync account and workspace that the app gets. Select Switch to use a different account. |
| It will be able to | Read conversations, send messages, and organize your inbox, with the permissions of your role. The app never sees your password. |
| Channel access | Every line that you can access, and the lines that you connect later. Select Change to limit the app to specific lines. |
Did you start this?
Select Cancel if you did not add CommSync to an app a moment ago. A sign-in request that you did not start can come from someone who wants access to your inbox.
Manage connected apps
Under Settings, in Connect AI apps, you see every app that you allowed. Each row shows the app, the lines it can use, and when it last called CommSync.
- Edit channel access changes the lines. The next request uses the change, and the app stays signed in.
- Disconnect stops the app at once, on every device. To use the app again, connect it from the app.
Right-click a row for the same actions.
Security
- The app never receives your password or an API key.
- The access token of the app lasts one hour, and the app renews it in the background.
- A renewal token changes at each use. If an old copy appears later, CommSync signs out that connection.
- CommSync stores only a hash of each code and token.
- A lead who acts as a teammate cannot connect or disconnect apps for that teammate. Neither can CommSync support.
