Connect your app - OnlySocial API

Before you start

You need:

An OnlySocial account in a workspace whose plan includes AI assistant (MCP) access.
An AI app that supports MCP connectors. Some apps only offer this on paid plans; each section below says what you need.
The server URL:
https://app.onlysocial.io/mcp

Once connected, the assistant can do what you can do in that workspace: read your accounts, posts and inbox, and create, schedule, publish and delete posts. Only connect apps you trust, and read what the assistant plans to do before you approve publishing, deleting or messaging customers.

How signing in works

It is the same in every app:

You add OnlySocial to the app with the server URL.
The app opens OnlySocial in your browser. Sign in as usual, with your two-factor code if you use one.
OnlySocial asks you to choose one workspace for this app. The app only ever sees that workspace. Only workspaces whose plan allows AI assistants are listed.
Check the address it says access will be sent to, then click Connect. You are sent back to the app and the connection is ready.

Cancel gives the app nothing. The app refreshes its access in the background, so you are not asked to sign in again unless you leave the connection unused for 90 days.

Want the assistant in a different workspace? Remove the connector in your app, add it again and choose the other workspace. Need several workspaces at once? Use a personal access token instead.

You need a Claude Pro, Max, Team or Enterprise plan. On Team and Enterprise, an organisation Owner may need to add the connector first.

In Claude on the web or Claude Desktop, open Settings → Connectors.
Click Add custom connector.
Name it OnlySocial and set the Remote MCP server URL to https://app.onlysocial.io/mcp.
Leave the OAuth client ID and secret empty: OnlySocial registers Claude by itself.
Click Add, then Connect, and sign in.

In a chat, open the tools menu below the message box and make sure OnlySocial is on. Then ask, for example, “List my OnlySocial workspaces.” The connector also works in the Claude mobile apps.Team and Enterprise: an Owner adds the connector under Organization settings → Connectors; each member then clicks Connect in their own Settings → Connectors and signs in with their own OnlySocial account.

You need a ChatGPT plan with custom connectors in Developer mode (such as Plus, Pro, Business, Enterprise or Edu). On Business, Enterprise and Edu a workspace admin may need to switch it on.

Open Settings → Apps & Connectors, then Advanced settings, and switch on Developer mode.
Back in Apps & Connectors, click Create.
Name it OnlySocial, set the MCP Server URL to https://app.onlysocial.io/mcp and Authentication to OAuth.
Tick I trust this application, click Create, and sign in when asked.

In a chat, click +, choose Developer mode and select OnlySocial. ChatGPT asks you to confirm before running tools that change things.OpenAI renames these menus from time to time; if you cannot find an option, search their help centre for “custom connectors”.

claude mcp add --transport http onlysocial https://app.onlysocial.io/mcp

Start Claude Code, type /mcp, choose onlysocial, then Authenticate, and sign in in the browser window that opens.

Open Cursor Settings → MCP and click Add new MCP server, which opens mcp.json. Add:

{
  "mcpServers": {
    "onlysocial": {
      "url": "https://app.onlysocial.io/mcp"
    }
  }
}

Save, click Needs login next to onlysocial, and sign in.

Run MCP: Add Server… from the Command Palette and choose HTTP, or create .vscode/mcp.json:

{
  "servers": {
    "onlysocial": {
      "type": "http",
      "url": "https://app.onlysocial.io/mcp"
    }
  }
}

Click Start above the entry, allow OnlySocial to sign you in, and sign in. The tools then appear in Copilot Chat’s Agent mode.

Use a personal access token

For scripts, servers and apps without OAuth. A token acts as you in every workspace you belong to, so keep it secret like a password.

Create the token

In OnlySocial, open Access Tokens from your user menu, click Create, give it a name and copy the token. It is shown once.

Send it as a Bearer token

Point your app at https://app.onlysocial.io/mcp with the header Authorization: Bearer <token>.

claude mcp add --transport http onlysocial https://app.onlysocial.io/mcp \
  --header "Authorization: Bearer $ONLYSOCIAL_TOKEN"

{
  "mcpServers": {
    "onlysocial": {
      "type": "http",
      "url": "https://app.onlysocial.io/mcp",
      "headers": {
        "Authorization": "Bearer <token>"
      }
    }
  }
}

{
  "mcpServers": {
    "onlysocial": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote", "https://app.onlysocial.io/mcp",
        "--header", "Authorization: Bearer ${ONLYSOCIAL_TOKEN}"
      ],
      "env": { "ONLYSOCIAL_TOKEN": "<token>" }
    }
  }
}

The token keeps working until you delete it under Access Tokens. Deleting it disconnects every app that uses it.

Check the connection

Ask the assistant to “list my OnlySocial workspaces”. If they come back, you are connected. If not, see Troubleshooting.

Disconnect

Remove the connector in your AI app (for example Settings → Connectors in Claude). For a token connection, also delete the token under Access Tokens in OnlySocial.
