Nombres y descripciones de las herramientas tal como los informó el servidor el 6 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.
addevent_list_calendarsList the account's calendars (newest first by default) with id, title, timezone, whether it is the default calendar, landing-page links and counts of events and subscribers. GET /calendars.
addevent_get_calendarOne calendar by id: title, timezone, week start, template ids, subscriber and event counts, links, custom data. GET /calendars/{id}.
addevent_create_calendarWRITE: creates a new calendar in the AddEvent account (a new, empty calendar; nothing existing is changed and nobody is notified). Needs a title. POST /calendars.
addevent_update_calendarWRITE: changes fields of an existing calendar (only the fields you pass; the rest stay). Title, description and timezone changes show on its landing page and can reach people who subscribe to the calendar feed. Not reversible by this server (no previous values are kept), so read
addevent_list_eventsSearch the account's events (newest created first; by start time when a date filter is used): title, start/end, timezone, location, RSVP settings and stats, landing-page links. Filter by calendar, event ids, text, date window or a custom_data pair. GET /events.
addevent_get_eventOne event by id (evt-...): all fields incl. description, organizer, reminder, recurring rule, RSVP settings and stats, custom data and share links. GET /events/{id}.
addevent_create_eventWRITE: creates a new event on a calendar (the account's default calendar if calendar_id is omitted). Creates a public event landing page and share links; it does not e-mail anyone, though people subscribed to that calendar's feed will see the event on their next sync. Needs title
addevent_update_eventWRITE: changes fields of an existing event (only the fields you pass; the rest stay). The change goes live on its landing page and share links, and people who subscribed to the calendar or added the event with a live link are updated on their next calendar sync, so a time or loca
addevent_list_rsvp_attendeesList RSVP attendees (personal data: e-mail addresses and the answers they gave on the RSVP form). Filter by calendar, event or response (going/maybe/not-going). Paged, 20 at most per page: read only what the task needs. IP address and coordinates are removed from the reply. GET /
addevent_get_rsvp_attendeeOne RSVP attendee by id (personal data: e-mail and form answers; IP address and coordinates removed). GET /rsvps/{id}.
addevent_create_rsvp_attendeeWRITE: adds ONE RSVP attendee (one e-mail address, personal data) to an event. This server never asks AddEvent to send the confirmation or organizer notification e-mails, but the event's own reminder and follow-up e-mails (if the event has them) will later go to this address, so
addevent_update_rsvp_attendeeWRITE: changes ONE RSVP attendee (email, response or form answers; only the fields you pass). The event's reminder and update e-mails go to the e-mail address stored here, so changing it redirects those e-mails to that person. This server never triggers the confirmation or organi
addevent_list_calendar_subscribersList people subscribed to the account's calendars (personal data: the form answers they gave, such as name and e-mail; calendar app type, sync status). Paged, 20 at most per page. IP address and coordinates are removed. GET /subscribers.
addevent_get_calendar_subscriberOne calendar subscriber by id (personal data; IP address and coordinates removed). GET /subscribers/{id}.
addevent_list_rsvp_formsThe account's RSVP forms (id, name), newest first. Use the id as rsvp_form_id on an event. GET /events/rsvp-forms.
addevent_list_event_templatesThe account's event landing page templates (id, name), newest first. Use the id as landing_page_template_id on an event. GET /events/templates.
addevent_list_calendar_templatesThe account's calendar landing page templates or embeddable calendar templates (id, name), newest first. Use the id as landing_page_template_id / embeddable_calendar_template_id on a calendar. GET /calendars/templates.
addevent_list_timezonesTimezone names AddEvent supports (use them as the timezone of events and calendars), with current UTC offset. Optional text filter on the name. GET /timezones.

Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.
El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.
Se ejecuta en la nube del creador. Te conectas por internet sin instalar nada, pero lo que envías pasa por los servidores del creador.
El repo de GitHub cambió por última vez –, y la última versión (1.22.3) llegó al registro ayer.
Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.
