About

Google Calendar ships in the w6w first-party pack. It declares 8 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Google Calendar checks availability and manages events from a workflow — creating an event with full detail or with Google’s own natural-language quick-add, updating or deleting an existing one, and reading a single event or listing everything on a calendar in a given range.

Availability is a purpose-built check, not something inferred from a list of events: a workflow can ask whether a person or resource is free before booking, the way a scheduling tool would. Multiple calendars are supported too — calendars can be listed, so a workflow isn’t locked to a single default one.

A fit for booking meetings triggered by an external event, keeping a calendar in sync with another scheduling system, or gating a workflow step on whether a time slot is actually free.

Build with Google Calendar

Three routes to the same 8 actions. The Workflow tab is generated from Google Calendar'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 Event

create-event

Insert an event on a calendar. `start` and `end` must be RFC 3339 timestamps (or dates when `allDay`).

Delete Event

delete-event

Delete an event by ID.

Get Availability

get-availability

Check whether a time slot is free or busy on a calendar via the FreeBusy API. `timeMin` and `timeMax` must be RFC 3339 timestamps.

Get Event

get-event

Retrieve a single event by ID.

List Calendars

list-calendars

List the calendars in the authenticated user's calendar list. Returns one page; pass `pageToken` for the next.

List Events

list-events

List events on a calendar. Returns one page; pass `pageToken` for the next. `timeMin`/`timeMax`/`updatedMin` must be RFC 3339 timestamps.

Quick Create Event

quick-create-event

Create an event from a natural-language string via `events.quickAdd`.

Update Event

update-event

Patch fields on an existing event. Only supplied fields are sent; omit a field to leave it untouched.

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 Google Calendar's real ids.

+3 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 Google Calendar, 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 Google Calendar. 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: "create-event",
  payload: {
    calendarId: "<value>",
    // summary: "<value>",
    // description: "<value>",
    // location: "<value>",
    start: "<value>",
    end: "<value>",

Give an AI agent Google Calendar — without giving it Google Calendar'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.google-calendar#create-event",
    "input": {
      "calendarId": "<calendarId>",
      "start": "<start>",
      "end": "<end>"
    }
  }
}

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 Google Calendar 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

Google Calendar'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. Google Calendar itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

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