Nolizi Calendar does not always answer

Over the last week it answered 95.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

available

list_available_slots

Return the live available start/end pairs for one event type. These are real times on a real calendar: show them to the person and let them choose. Do not invent, extrapolate or round a time that is not in this response. Convert times for display only — pass the original values back to create_booking unchanged.

booking

create_booking

Book a real meeting. This sends invitations and writes to connected calendars, and it cannot be undone except by cancelling. Ask the person to confirm the event, the exact time and the attendee details before calling it, and use their real name and email — never a placeholder. The start and end must be copied verbatim from a recent list_available_slots response; this server re-checks them against live availability and refuses times it cannot find. There is no idempotency key: if this call returns an uncertain outcome, do not call it again — call list_upcoming_bookings and read what actually happened.

cancel

cancel_booking

Cancel a confirmed booking. This notifies the attendee and removes the meeting from connected calendars, and it cannot be undone. Use an exact booking_id taken from list_upcoming_bookings — never a guessed or reconstructed one. Cancelling one occurrence of a grouped or recurring booking can affect several meetings, so confirm with the person which meetings they mean.

event

list_event_types

List the bookable event types owned by the configured Nolizi Calendar account. Start here: the returned slug is what every other tool needs. Never guess a slug. Events with required custom questions or email verification cannot be booked through this API — send the person to the event’s public booking page instead.

upcoming

list_upcoming_bookings

List up to 100 upcoming confirmed bookings. This is the only way to verify that a booking exists. Use it after every create or cancel, and use it first whenever a write returned an uncertain outcome.

Nolizi Calendar — questions

Answers built from our own checks of this server.

What can Nolizi Calendar do?

It exposes 5 tools, read directly from the server on our last check. Among them: cancel_booking, create_booking, list_available_slots, list_event_types, list_upcoming_bookings. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Nolizi Calendar working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 86 of 91 checks got a reply (94.5%), average response time 191 ms. The bar chart above shows every period we have measured.

The registry lists Nolizi Calendar as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Nolizi Calendar?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Nolizi Calendar need an API key?

No. Nolizi Calendar completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Nolizi Calendar?

It answers our handshake in 191 ms on average, which is faster than 74% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
