Manage events, guests and ticket types on a Luma calendar.
Luma ships in the w6w first-party pack. It declares 29 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.lumaLuma runs a calendar’s events end to end from a workflow: create, update, cancel and read events; manage ticket types, including paid ones on a calendar with a connected Stripe account; add, invite, approve, decline, waitlist and re-ticket guests; and add or remove event hosts.
Each connection is scoped to exactly one calendar, matching how Luma issues API keys — the calendar a workflow acts on is whichever calendar the connected key was generated for, with no separate calendar-id field to get wrong. Calendar-level actions cover the calendar’s own settings, its admins, its contact list, and reviewing events submitted to it (list, look up, approve or reject a pending submission).
A fit for syncing registrations into a CRM, automating check-in or waitlist promotion logic Luma’s own dashboard doesn’t offer, keeping a calendar’s contact list in sync with an external list, or triggering follow-up workflows off guest status changes. This app covers events, guest/registration management, ticket types, hosts, calendar administration and contacts as documented in Luma’s public OpenAPI 3.1 spec; it does not cover coupons, event/contact tags, webhooks, memberships, organizations or image uploads — none of those were verified against the live API for this build.
Three routes to the same 29 actions. The Workflow tab is generated from Luma'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.
calendar-events-add Add an event to the connected calendar — an existing Luma event by ID, or an external (non-Luma) event by URL.
calendar-events-approve Approve a pending event submission on the connected calendar.
calendar-events-lookup Look up an event's submission status (approved/pending/rejected) on the connected calendar, by Luma event ID or by external URL.
calendar-events-reject Reject a pending event submission on the connected calendar.
calendar-update Update the connected calendar's name, slug, description, avatar or accent color.
contact-list List contacts on the connected calendar, with search, tag and membership filters.
event-cancel Confirm cancelling an event, using the cancellation_token from Request Event Cancellation.
event-cancel-request Start cancelling an event. Returns a short-lived cancellation_token (15 minutes) plus whether the event has paid guests — pass both to Confirm Event Cancellation.
guest-send-invites Send soft invites (accept/decline) to one or more people for an event.
guest-update-status Approve, decline, waitlist or re-queue a guest for approval.
guest-update-tickets Invalidate a guest's existing tickets and/or grant complimentary ones.
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 Luma's real ids.

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 Luma, 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 Luma. The Workflow tab is where this app's
real ids are.

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.luma#calendar-events-add",
"input": {
"platform": "<platform>"
}
}
}
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 Luma connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
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.
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.
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.
Luma'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. Luma itself is MIT, and the runtime that executes it is source-available (FSL).
Luma declares its own checks, so its health is a property of the app rather than something the host guesses at.
Luma's Statuspage subdomain (luma.statuspage.io) is claimed but returns 401 "page is inactive" on every API path, so no machine-readable status surface is available.
