Nolizi MCP server

Which MCP servers are Nolizi's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

Whose server it is
  • Registry namecom.nolizi.calendar/calendarverified in the MCP registry

The registry name sits under nolizi.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 136 ms.

Should an agent connect itSkip it
  • Its tools do none of the product's use cases we checked: collect e-signatures with an audit trail; publish a local machine port at a public address.

Once connected

  • create_booking, cancel_booking change data without a sign-in: anyone with the address can call them.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?

Worth a look

  • Tools that change data, on a server that answers without a sign-in: create_booking, cancel_booking

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

Tools it offers5 tools · read 2026-10-24
  • 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…

  • 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…

  • 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.

  • 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…

  • 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…

How to connect

Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:

{
  "mcpServers": {
    "calendar": {
      "type": "http",
      "url": "https://calendar.nolizi.com/mcp"
    }
  }
}

Add it

Claude Code, in a terminal

claude mcp add --transport http nolizi https://calendar.nolizi.com/mcp

Add to CursorAdd to VS Code

claude.ai, ChatGPT and other clients: add https://calendar.nolizi.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
