Google Calendar: Schedule Meetings and RSVPs

List events, create meetings, check availability, and manage RSVPs in Google Calendar. OAuth credentials are injected automatically.

Per-app Google setup is deprecated. All Google apps now share one Google OAuth client and one Redirect URI. To use your own client, follow the Google setup guide. Credentials saved for one Google app apply to all of them.

Overview

OneCLI connects AI agents to Google Calendar through Google’s OAuth flow. Agents can list upcoming events, create new meetings, check availability, and manage RSVPs. The gateway injects OAuth credentials into requests to the Google Calendar API automatically.

This is useful for scheduling agents, meeting coordinators, or any agent that needs awareness of your calendar.

Connect on OneCLI Cloud (one click)

1. Go to Connections

   Open the OneCLI dashboard and navigate to Connections > Google Calendar.

2. Authorize

   Click Connect Google Calendar. You’ll go straight to Google: pick your account, review the permissions, and click Allow. No Google Cloud setup needed.

On self-hosted OneCLI, or to use your own Google client on Cloud, see Use your own Google client.

Use your own Google client

This is for self-hosted OneCLI, and for OneCLI Cloud when you choose Custom credentials instead of one-click. One Google client serves every Google app in OneCLI, so you set it up once. If you already did it for another Google app, skip to step 2.

1. Set up your Google client

Follow the Google setup guide. It enables the Google APIs, sets up the consent screen, creates the OAuth client, and adds the Redirect URI.

You paste the client into Connections > Google Calendar > Custom credentials, under the Redirect URI the guide asks you to register:

Custom credentials for Google Calendar in OneCLI.

2. Connect Google Calendar

Open Connections > Google Calendar, select Connect Google Calendar, pick your Google account, and click Allow.

The Google Calendar connect window before a Google client is set up.

What agents can do

• List events on any of your calendars within a date range
• Get details for a specific event (attendees, location, video link, description)
• Create new events with attendees, location, and conferencing
• Update existing events (reschedule, change attendees, modify description)
• Delete or cancel events
• Check free/busy availability for one or more people
• Respond to event invitations (accept, decline, tentative)
• List all calendars on the account
• Create and manage secondary calendars

Controlling access

Access is per agent: grant the connection to each agent that needs it, choosing per tool what runs freely, what needs human approval, and what stays blocked — a read-only agent is a single grant. Organization rules add guardrails on top, like rate limits and blanket blocks. Everything is checked before credential injection, so a blocked request never reaches Google Calendar.
