Automate Google Calendar with OpenClaw: Smart Scheduling Agent

Stop managing your calendar manually. Use OpenClaw to read, create, and optimize Google Calendar events, find meeting slots, and send reminders — all from your chat.

Your calendar shouldn't be a manual filing system. OpenClaw reads your Google Calendar, finds free slots, creates events, sends reminders, and optimizes your schedule — all through natural language in your chat.


What you can do with Google Calendar + OpenClaw

Once connected, your OpenClaw agent can:

  • Read upcoming events and free/busy times
  • Create new events with title, description, location, and attendees
  • Find available meeting slots across multiple calendars
  • Send reminders before events
  • Detect scheduling conflicts
  • Suggest schedule optimizations
  • Post daily/weekly agenda summaries to Telegram or Slack

Prerequisites

  • OpenClaw installed and running
  • Google Service Account with Google Calendar API access, or
  • Codex native plugin for Google Calendar (if using Codex harness)

Setup: Google Calendar API

  1. Go to Google Cloud Console
  2. Enable Google Calendar API
  3. Create a Service Account and download the JSON key
  4. Share your calendar with the service account email (e.g., my-agent@project.iam.gserviceaccount.com)
  5. Store the key file securely and reference it in OpenClaw config

Alternatively, if you're using the Codex harness, install the Google Calendar plugin through the Codex marketplace and migrate it to OpenClaw via openclaw migrate codex.


Workflow 1: Daily Morning Briefing

The problem: You open your laptop and have to check calendar, prioritize meetings, and figure out what the day looks like.

The workflow:

Good morning. What's on my calendar today?

          For each meeting, tell me:
          - Time and duration
          - Who I'm meeting with
          - The agenda (from the event description)
          - Any prep I need to do

          Also flag:
          - Meetings with no agenda
          - Back-to-back meetings with no break
          - Any conflicts
          

Schedule it for 8 AM every day:

{
            schedule: { kind: "cron", expr: "0 8 * * *" },
            payload: {
              kind: "agentTurn",
              message: "Give me my daily calendar briefing. Read today's events, summarize each, flag conflicts and back-to-back meetings."
            }
          }
          

What the agent does:

  1. Reads today's events via Google Calendar API
  2. Formats each meeting with time, attendees, and description
  3. Identifies meetings without agendas
  4. Detects back-to-back meetings (no buffer)
  5. Flags scheduling conflicts
  6. Posts the briefing to your Telegram or Slack

Workflow 2: Smart Meeting Scheduling

The problem: Coordinating a meeting between 3 people across different time zones with different availability is a nightmare of "does Tuesday at 2pm work for you?"

The workflow:

I need to schedule a 45-minute meeting with Sarah (sarah@company.com) and John (john@company.com) next week.

          Requirements:
          - Between Monday and Thursday
          - Between 10 AM and 4 PM (my timezone: Europe/Berlin)
          - Both Sarah and John must be free
          - I need 15 minutes before to prep

          Find 3 options and create the event for the first one that works.
          

What the agent does:

  1. Reads your calendar for next week
  2. Reads free/busy info for Sarah and John (if they've shared availability)
  3. Finds overlapping free slots
  4. Adds 15-minute prep buffer before each option
  5. Presents 3 options
  6. Creates the event with attendees, agenda, and meet link

Workflow 3: Meeting Prep Automation

The problem: You have back-to-back meetings and no time to prepare. You need context on who you're meeting and what was previously discussed.

The workflow:

I have a meeting with David from Acme Corp at 2 PM.

          Prepare a brief:
          1. Check my calendar — what's the meeting about?
          2. Do I have any previous meetings with David? Summarize them.
          3. Check my email for any threads with David in the last 2 weeks
          4. Summarize what I need to know before this meeting

          Send the brief to my Telegram 30 minutes before the meeting.
          

What the agent does:

  1. Reads the calendar event for details and agenda
  2. Searches calendar history for previous meetings with David
  3. Searches Gmail for recent email threads
  4. Compiles a 1-page brief with context
  5. Sends it to Telegram 30 minutes before

Schedule it for every meeting with external attendees:

{
            schedule: { kind: "cron", expr: "30 13 * * *" },
            payload: {
              kind: "agentTurn",
              message: "Check my 2 PM meeting, prepare a brief, and send to Telegram."
            }
          }
          

Workflow 4: Conflict Detection and Resolution

The problem: You accept meeting invitations throughout the day. Sometimes they overlap. You find out 5 minutes before when you see two notifications pop up.

The workflow:

Check my calendar for the next 7 days.

          Flag any:
          1. Overlapping events (direct conflicts)
          2. Events with less than 15 minutes between them (no transition time)
          3. Meetings scheduled outside my working hours (8 AM - 6 PM)

          For each conflict, suggest which meeting to move and propose 3 alternative times.
          

Schedule it to run every evening:

{
            schedule: { kind: "cron", expr: "0 18 * * *" },
            payload: {
              kind: "agentTurn",
              message: "Check my calendar for next 7 days. Flag conflicts, back-to-backs, and after-hours meetings. Suggest alternatives."
            }
          }
          

Workflow 5: Weekly Schedule Optimization

The problem: Your calendar is full of meetings that could be emails, recurring meetings that no longer serve a purpose, and time slots that don't align with your energy levels.

The workflow:

Analyze my calendar from the last 4 weeks:

          1. How many hours per week in meetings?
          2. What % of meetings were recurring vs. one-off?
          3. Which recurring meetings had no agenda in the last 4 weeks?
          4. Which days had the most back-to-back meetings?
          5. How much focus time (2+ hour blocks) did I have?

          Recommend:
          - 3 recurring meetings I should consider cancelling or reducing frequency
          - Best time blocks for deep work based on my meeting patterns
          - One scheduling rule I should adopt
          

What the agent does:

  1. Reads 4 weeks of calendar data
  2. Categorizes meetings (recurring, one-off, with/without agenda)
  3. Calculates focus time and meeting density per day
  4. Identifies patterns (e.g., "Your Tuesdays are 80% meetings")
  5. Generates actionable recommendations

Tips for calendar automation

Use natural language

The agent understands "next Tuesday at 2 PM" or "in 3 days at 10 AM." You don't need to format dates.

Combine with other tools

Calendar + Gmail: Prepare meeting briefs with email context Calendar + Slack: Post a daily schedule to your team channel Calendar + Google Sheets: Log meeting hours per week for time tracking Calendar + Notion: Create meeting notes pages automatically

Set working hours

Tell the agent your working hours once and it will respect them when scheduling:

Remember: my working hours are 8 AM to 6 PM, Monday through Friday. Don't schedule meetings outside these hours unless I explicitly ask.
          

Use reminders strategically

Remind me 15 minutes before any meeting with external attendees. Remind me 5 minutes before internal meetings.
          

FAQ

Does the agent need access to my full Google account?

No. The service account only has access to calendars you explicitly share with it. You can restrict it to specific calendars.

Can the agent reschedule meetings?

Yes, if it has edit access to the calendar. The agent can modify event times, add/remove attendees, and update descriptions. Always review changes before they're applied.

Can it check other people's availability?

Only if they've shared their free/busy information with your service account or if you're on the same Google Workspace domain and have permission to view their calendars.

What time zones does it support?

All of them. The agent reads time zone info from the calendar API and can convert between zones. Specify your time zone once and the agent handles conversions.

Can I use the Codex plugin instead of the API?

Yes. If you're running OpenClaw with the Codex harness, install the Google Calendar plugin from the Codex marketplace. It provides the same capabilities through Codex's native app integration.
