Begin MCP Begin exposes a Model Context Protocol (MCP) server, so you can ask Claude or ChatGPT about your schedule, your hours, and anything else in your workspace — without leaving the chat. The connection signs in with your Begin account and uses the same permissions you already have.

​
What you can do

Once connected, your AI client can answer questions about everything you can see in the web app: your schedule, your hours, the team’s schedule for your locations, time-off requests, and messages. Read tools answer immediately.
Your MCP connection has the same access as your account in Begin. It can’t do anything you can’t already do in the web app — if you don’t have permission for something, you’ll see a clear “Permission denied” response.

​
Example prompts

Check your next shift.

Total your hours for the week.

See who's working with you.

Review your time-off requests.

Plan your week.

​
Connect Claude

The path is the same on Claude on the web (claude.ai) and Claude Desktop.
1

Open the connector setup

In Claude, go to Settings → Connectors → Add custom connector.
2

Paste the connector URL

Use https://api.begin.eu/mcp.
3

Sign in to Begin

Claude opens a browser tab. Use your normal sign-in method: phone OTP, email OTP, passkey, or Google.
4

Approve the consent screen

Confirm the connection to finish.
Custom connectors are available on Claude Free, Pro, Max, Team, and Enterprise. Free is capped at one custom connector.

​
Connect Claude Code

If you use Claude Code in your terminal, register Begin as a remote MCP server with one command. 
claude mcp add --transport http begin https://api.begin.eu/mcp
Then run /mcp inside Claude Code to authenticate. Claude Code opens a browser window to sign in to Begin and approve the connection. Subsequent sessions reuse the cached token.

​
Connect ChatGPT

ChatGPT requires turning on Developer mode before you can create an app.
1

Open Advanced settings

In ChatGPT, click your profile picture and go to Settings → Apps → Advanced settings.
2

Turn on Developer mode

Toggle Developer mode on.

5

Sign in to Begin

In the popup, sign in and approve the consent screen.
Custom apps are available on ChatGPT Pro, Plus, Business, Enterprise, and Education. They aren’t available on Free. On Business, Enterprise, and Education, your workspace admin needs to enable Developer mode for you.

​
Workspace pinning

If you belong to more than one Begin workspace, your MCP connection is pinned to whichever workspace is active the first time your client uses the connection. Once pinned, switching workspace in the web app does not change the workspace your MCP client uses. To switch:
1

Switch your active workspace

In the Begin web app, set the target workspace as active.
2

Revoke the existing connection

In Settings → Security → Connected MCP clients, revoke the current pin.
3

Reconnect from your MCP client

Your next request pins to the new workspace.

​
Manage connected clients

Settings → Security → Connected MCP clients shows every MCP client you’ve authorized, the workspace each is pinned to, and when each was last active. Revoke a client anytime.

​
Permissions and security

  • Your MCP connection has the same permissions as your account. Never more.
  • Connections are scoped to one workspace at a time.
  • Tokens are short-lived (1 hour) with refresh-token rotation; clients refresh them silently.
  • Every action is written to the workspace audit log under your name.
