Run Luma events end to end - create and update events, ticket types, and discount coupons, then manage guests through invites, approvals, waitlists, and re-ticketing. Built for automating event setup and guest operations, and reporting on registrations and check-ins from an agent.
ChatGPT is OpenAI's assistant. It can add custom MCP servers as plugins, which lets it call your tools from a conversation.
This guide connects Luma to ChatGPT through MewCP, so ChatGPT can use Luma's 18 tools, like get_event, get_guest and get_ticket_type, without your Luma credentials ever reaching the app.
Your Luma API key is stored encrypted and injected only at call time. Your agent never holds it, so it can never leak it, log it or paste it into a prompt.

Other clients
Luma works the same way in every client below. Pick yours for its own guide.
Free to start.
Scope access to the exact Luma tools and accounts you allow, work and personal side by side. Anything outside that scope is refused at call time, even when the model asks for it.
Each call is logged: what ran, on which account, and whether it worked. Failures come back structured, so the agent knows whether to retry instead of guessing.
Every app sits behind one secure MCP URL, and there is no server for you to deploy or keep running. Add an integration in the dashboard and it is live on the next call, with no config to change and no new credentials to wire up. Tools load only when a task needs them, so your agent stays fast and focused however many apps you connect.
In ChatGPT, open Plugins and choose Add custom MCP.

Retrieves the full details of a single event you have manage access for, including hosts and a breakdown of guest counts by status.
Retrieves the details of a single guest for an event, including ticket order details.
Retrieves the details of a single ticket type.
Returns a paginated list of coupons associated with an event.
Returns a paginated list of guests who have registered or been invited to an event, including guest summaries and event_tickets (use get_guest for order-level detail).
Returns the full list of ticket types for an event in one response (not paginated).
Requests a short-lived cancellation token and impact preview (guest count, whether paid) for an event — the first step of Luma's two-step cancellation flow.
Creates a new event and returns its id.
Creates a new ticket type for an event and returns the created ticket type, including its id.
Creates a new discount coupon for an event and returns the created coupon.
Adds one or more guests directly to an event (default status "Going", one ticket of the default type unless overridden) and returns an empty response on success.
DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Sends one or more guests a soft invite to an event by email (and SMS if their phone is linked to their Luma account) that they can accept, returning an empty response on success. This sends real communications to every listed guest — the original invite state is not returned and cannot be recovered from this call. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user exactly which guests will be invited and what the message will say, and wait for their explicit written confirmation before proceeding.
DESTRUCTIVE — REQUIRES EXPLICIT USER CONFIRMATION BEFORE CALLING. Cancels an event using a cancellation token from request_event_cancellation and returns an empty response on success. This action is irreversible — the event is deleted, all guests are notified, and refunds are processed if requested; the event cannot be recovered after this call. NEVER call this tool autonomously or as part of an automated flow. You MUST stop, tell the user exactly what event will be permanently cancelled and that it is irreversible, and wait for their explicit written confirmation before proceeding.
Updates an existing event's details. Only the fields you provide are changed — others keep their current value. NOTE: this overwrites the current field values, and the original values are not preserved after the call — the response includes both the before and after state (fetched via the same lookup as get_event) so you have a full record of what changed.
Updates a guest's status (approved, declined, pending_approval, or waitlist), optionally refunding them and/or emailing a personal message. NOTE: this overwrites the guest's current status, and the original status is not preserved after the call — the response includes both the before and after state (fetched via the same lookup as get_guest) so you have a full record of what changed.
Administratively adds complimentary tickets to or removes/invalidates tickets from an existing guest with no payment or refund processed. NOTE: this overwrites the guest's ticket set, and the original ticket set is not preserved after the call — the response includes both the before and after state (fetched via the same lookup as get_guest) so you have a full record of what changed.
Updates an existing ticket type's details and returns the updated ticket type. Only the fields you provide are changed — others keep their current value. NOTE: this overwrites the current field values — the original state is not stored after the call. The response includes both the before and after state so you have a full record of what changed.
Retrieves details for a calendar and returns its metadata, including name, slug, URL, description, location, coordinates, and social handles.
