Example Prompts

Here are some prompts that work well with Google Calendar MCP: View Schedule: 
List events on my primary calendar tomorrow between 8 AM and 6 PM. Return summary, start, end, and location.
Schedule Meeting: 
Create a 45-minute event titled "Marketing Sync" on 2025-06-10 at 11:00 AM EST with attendees jane@example.com and tom@example.com. Return event id, summary, and hangoutLink.
Update Meeting Details: 
Update event id abcd1234 so the description reads "Updated agenda attached". Return summary and description.
Availability Check: 
Check free slots on calendar work@example.com on 2025-06-12 from 1 PM to 5 PM EST, 15-minute intervals. Return start and end for each free slot.
Manage Attendees: 
Set attendee status for bob@example.com to declined on event id abcd1234. Return attendee email and responseStatus.
For best results, start with a single, precise action. Once that prompt works, duplicate the node and tweak the prompt for variations instead of packing multiple commands into one request.

​
Troubleshooting

If your Google Calendar MCP node isn’t working as expected, try these best practices:

​
Keep Prompts Simple and Specific

  • Good: “List events on June 5th between 9 AM and 5 PM PST. Return summary and start.”
  • Less Efficient: “List my events for next week, then create a new event for any empty slot and invite xyz@domain.com.”
While the less efficient example might work, it’s more efficient to break it into separate nodes. Google Calendar MCP works best with focused, single-action prompts.

​
Match What Google Calendar Can Do

  • Good: “Delete event id 123abc on my primary calendar.”
  • Bad: “Delete event id 123abc and update my Slack status to ‘Meeting canceled’.”
Google Calendar MCP excels at calendar management. For Slack updates, use a separate Slack node.

​
Break Complex Tasks Into Steps

Instead of trying to do everything in one prompt (which might cause timeouts or confusion): 
For every client on my spreadsheet, find a free 30-minute slot next week, create a meeting, invite the client, and email them the invite.
Break this into smaller, focused nodes that each handle one task:
1

Step 1: Check Free Slots

Check free slots on my primary calendar next week, 30-minute windows. Return start and end.
2

Step 2: Create Meetings

Create an event titled “Client Call” at each provided start time and invite the given email. Return event id and start.
3

Step 3: Send Emails

Send an email via Gmail Sender to each client with their meeting details using the returned event id and start time.
In your workflow, connect these nodes sequentially. The free slot output from Step 1 feeds into Step 2, and the event ids from Step 2 feed into Step 3.

​
Focus on Data Retrieval

Google Calendar MCP is great at getting information from your calendars. For analysis or content creation, connect it to other nodes. Example:
  • Good prompt: “List events next Monday and return summary and duration.”
  • Bad prompt: “List events next Monday and write a detailed summary of each meeting for a newsletter.”
Use Ask AI to write summaries after the Calendar data is retrieved. Keeping tasks separate speeds up execution.
