For people
One booking link over every calendar
Guests see your real free time across all your accounts, pick a slot in their own time zone and get an invite. They can reschedule or cancel from the link in their confirmation.

Questions
Frequently asked questions
What is neosfy?
neosfy is a scheduling service. It reads your Google, Microsoft and Zoho calendars as one availability, gives people a booking link, and gives AI agents an MCP server to check free time and book meetings on your behalf.
How is neosfy different from Calendly or Cal.com?
Calendly and Cal.com are built for people clicking a booking page. neosfy has the booking page too, and it is also built for AI agents: an agent connects over the Model Context Protocol with a scoped key and reads availability, lists events and creates, moves or cancels meetings directly.
What is MCP?
MCP, the Model Context Protocol, is the open standard AI assistants such as Claude use to call outside tools. neosfy runs an MCP server, so any MCP client can use your calendars with the permissions you give it.
Which calendars does neosfy support?
Google Calendar, Microsoft Outlook and Microsoft 365, and Zoho Calendar. You can connect several accounts and neosfy combines their busy time into one availability.
What can an agent do with my calendar?
Only what its key allows. Every key carries a scope that names the tools it may call and the calendar accounts it may reach, and anything outside it is refused. You can revoke a key at any time.
How are my calendar credentials stored?
Calendar tokens are encrypted with AES-256-GCM under a key that belongs to your account alone, and they are never shown to agents.
Is there a free trial?
Yes. Every account starts with a 14-day free trial with two calendar accounts and two agent keys.
