About

AddEvent ships in the w6w first-party pack. It declares 22 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

AddEvent turns a date and a title into a working “add to calendar” link — one that opens correctly in Google Calendar, Apple Calendar, Outlook, Office 365 and Yahoo without the caller having to know each vendor’s own calendar-link format. This app covers AddEvent’s Calendar & Events API v2: full CRUD on events and the calendars that hold them, RSVP attendee management for events that require a response, read access to a calendar’s subscribers, and lookups of the account’s saved RSVP forms, landing-page templates and supported timezones.

The shape of most workflows against this API is small: create or update an event when something happens in your own system (a booking, a webinar, a lifecycle change), and every event comes back with link_long/link_short URLs ready to hand to a user or drop in an email. RSVP-enabled events additionally track seat limits and going/maybe/not-going counts, and a workflow can react to a new RSVP attendee or read the roster of a subscribed calendar.

Health checks track AddEvent’s own status page. AddEvent publishes no rate-limit or usage-quota signal of any kind — no response headers, no metering endpoint — so that question is answered as a declared absence rather than guessed at.

Build with AddEvent

Three routes to the same 22 actions. The Workflow tab is generated from AddEvent's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.

Create Calendar

calendar-create

Create a new calendar.

Delete Calendar

calendar-delete

Permanently delete a calendar by id. Cannot be undone.

Retrieve Calendar

calendar-retrieve

Fetch one calendar by id.

Search Calendars

calendar-search

Search calendars you've previously created. An empty result is a successful "no matches" response.

Delete Calendar Subscriber

calendar-subscriber-delete

Permanently delete (unsubscribe) a calendar subscriber by id. Cannot be undone.

Retrieve Calendar Subscriber

calendar-subscriber-retrieve

Fetch one calendar subscriber by id.

Search Calendar Subscribers

calendar-subscriber-search

Search subscribers to your calendars. An empty result is a successful "no matches" response.

List Calendar Templates

calendar-template-list

List your custom calendar landing-page or embeddable-calendar templates, sorted by creation date, newest first.

Update Calendar

calendar-update

Update a calendar. Only the fields you set are changed; everything else is left as-is.

Create Event

event-create

Create a new calendar event and get back its add-to-calendar links.

Delete Event

event-delete

Permanently delete an event by id. Cannot be undone.

Retrieve Event

event-retrieve

Fetch one event by id.

Search Events

event-search

Search events you've previously created. An empty result is a successful "no matches" response.

List Event Templates

event-template-list

List your custom event landing-page templates, sorted by creation date, newest first.

Update Event

event-update

Update an event. Only the fields you set are changed; everything else is left as-is.

Create RSVP Attendee

rsvp-attendee-create

Record an RSVP response for an event on the attendee's behalf.

Delete RSVP Attendee

rsvp-attendee-delete

Permanently delete an RSVP attendee by id. Cannot be undone.

Retrieve RSVP Attendee

rsvp-attendee-retrieve

Fetch one RSVP attendee by id.

Search RSVP Attendees

rsvp-attendee-search

Search RSVP attendees previously created. An empty result is a successful "no matches" response.

Update RSVP Attendee

rsvp-attendee-update

Update an RSVP attendee. Only the fields you set are changed; everything else is left as-is.

List RSVP Forms

rsvp-form-list

List your custom RSVP forms, sorted by creation date, newest first.

List Timezones

timezone-list

List every timezone AddEvent supports, sorted by UTC offset.

A workflow step names the app and the action, and the editor fills in the connection when you pick one. This is the Step shape from the workflow spec, carrying AddEvent's real ids.

+17 more actions available

Every app-specific value here is a blank you have to fill in. An app action is reached through the connection that authenticates it, so the address is a connection id, not the app id — and connections belong to your account, so a public page cannot know yours. Create one for AddEvent, then fill in the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the parameters that action declares. The call itself is real — the shape is transcribed from the studio's own snippet builder, which prints the same kind of blanks — but nothing in it is specific to AddEvent. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "calendar-create",
  payload: {
    title: "<value>",

Give an AI agent AddEvent — without giving it AddEvent's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.

One tool call
{
  "name": "w6w_invoke",
  "arguments": {
    "ref": "app:io.w6w.addevent#calendar-create",
    "input": {
      "title": "<title>"
    }
  }
}

Every tool names its target with a single ref. The app: form above doesn't name a connection at all — the host resolves which of the caller's AddEvent connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.

A tool surface scoped to the caller

Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.

A durable workflow in one call

Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.

Health-aware discovery

AddEvent's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.

The MCP surface is part of the hosted platform. AddEvent itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

AddEvent declares its own checks, so its health is a property of the app rather than something the host guesses at.
