Connect Claude & ChatGPT to CalendarHero

Ask your AI what is on your calendar this week, or to set up a meeting with a contact in CalendarHero. It can list meetings and meeting requests, create new requests from your meeting types, send reminders to invitees and keep your contacts up to date. Scheduling questions get answered in the chat instead of in the CalendarHero app.

Try asking

“What meetings do I have until Friday?”
The AI lists your calendar meetings up to the end date you give it.
“Set up a 30-minute call with [email protected] sometime next week.”
It looks up your meeting types, then creates a meeting request for next week with Jane as invitee. CalendarHero may contact her to schedule it.
“Which meeting requests are still open?”
It lists your meeting requests filtered by state, so you can see which ones are not scheduled yet.

What your AI can do

Meetings and requests

List calendar meetings, list meeting requests by state or type, create new requests and send reminders to invitees.

“Send a reminder to the people on the Acme kickoff request.”
It finds the meeting request and sends a reminder to its invitees.
“Add Peter Jensen from Nordic Foods as a contact.”
It searches your contacts first to avoid a duplicate, then creates the contact with name, email and organization.
“How did my meetings break down last month?”
It reads the statistics for your meeting categories for that month.

Questions

What can the AI do in CalendarHero?

It can list your meetings, meeting requests and meeting types, read meeting statistics and search your connected apps. It can create and delete meeting requests, send reminders to invitees, and search, create, update and delete contacts. It can also read your own profile and organization details.

Does the AI see my CalendarHero credentials?

No. Your CalendarHero API token is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with only reading meetings and contacts. Sending reminders reaches your invitees, and deleting a contact or meeting request cannot be undone, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own CalendarHero account.

Will CalendarHero contact my invitees?

It can. When the AI creates a meeting request, CalendarHero may contact the invitees to schedule it, and the reminder tool sends a message to them. If you want to check each one first, set these tools to require your approval.
