Use momo from an AI chat
Turn an AI chat request into a confirmed meeting — across calendars and external participants.
Setup
The connector address is https://mcp.momo.ai/mcp.
In Claude, add that address as a custom connector. Sign-in happens in the connector settings.
Claude does not offer sign-in inside the chat.
In ChatGPT Business, with developer mode, add the same address.
ChatGPT Enterprise and ChatGPT Edu were not part of the 9 October 2026 registration test, so this page does not say they work.
Preview and approval
A write shows a preview first. momo sends no mail and books no meeting until you approve that preview.
ChatGPT does not ask before a destructive tool call. The preview is the approval.
You are responsible for the mails an AI client sends through your account. The preview is where you decide that a mail may go out.
Calendars
momo uses the calendars already connected to your account: Google, Microsoft 365, and a CalDAV calendar you connected yourself, including iCloud.
Connecting CalDAV is the same capability as in email scheduling. MCP does not add a separate CalDAV feature and does not use a CalDAV plan flag as an access check.
Privacy boundaries
momo receives the parameters of the tool call, not the conversation in your AI client. The AI client processes that conversation itself.
A tool result contains status, times and email addresses. It does not contain event titles, the text of a mail, or free text from other participants.
momo, the MCP service and the authorization service each keep their own audit record: the event, the time, the service, an account id, the OAuth client id, the result and a request id.
The audit record does not contain mail text, calendar details or a recipient list. These records are deleted after 12 months.
The privacy policy is at momo.ai/privacy.
Examples
- Find a 45-minute time next week with sam@example.com and email them the options.
- Check whether Tuesday afternoon works for sam@example.com and me.
- Book the Tuesday 10:00 slot from the preview with sam@example.com.
- Move my meeting with sam@example.com to Thursday afternoon.
- Cancel the meeting with sam@example.com and tell them the project moved.
- Show my open scheduling requests.
Questions
Why use momo instead of the built-in calendar connector?
A built-in calendar connector reads one calendar. momo coordinates a meeting with other people, emails them, and books the time after you approve the preview.
momo shows as disconnected
If the connector shows as disconnected after you revoke access, reset your password, or the 90-day grant ends, reconnect it in the client's connector settings.
