Checkin MCP Server

Checkin offers a Model Context Protocol (MCP) server that gives AI assistants such as Claude, ChatGPT, and other MCP-compatible tools direct access to your event data.

With the MCP integration, you can ask the AI questions such as:

• “Show me an overview of the Annual Conference”
• “Who didn’t attend the last event?”
• “Compare ticket revenue from the last three events”
• “Find all registrations from contacts in Copenhagen”

Get started

To use Checkin in Claude, add a new custom connector with this URL:

https://mcp.checkinevent.com

Follow Anthropic’s instructions on how to do this for your Claude plan.

Then click Connect, and you’ll be redirected to Checkin’s authorization page. There, confirm that Claude should be granted access. You’ll then be automatically redirected back to Claude and ready to use it.

If you’re using another AI assistant that supports MCP servers, see their help articles for instructions on how to add a new MCP server.

Available Tools

The MCP server offers 9 tools divided into two categories.

Search and Lookup

Tools	Description
find-events	Start here when you want to work with a specific event. Search by name, date, or location to find what you're looking for.
find-attendees	Search for attendees by name or email. Filter by ticket type or check-in status. You can also have it retrieve an overview of allergies and accessibility needs.
find-orders	Find individual orders by searching by name, email, or invoice number. You can filter by payment status to view, for example, unpaid or refunded orders.
find-contacts	Look up a person across all events and view their entire history—past registrations, orders, and contact information.

Analysis and Reporting

Tools	Description
event-dashboard	Get a complete status report for an event—sales, capacity, check-ins, and more. Request more in-depth analysis, such as sales velocity, waitlist status, or a summary after the event has ended.
event-sales	Dive into the sales data for an event. You can request an overview, view sales over time, analyze add-ons, or get a breakdown of discounts applied.
event-check-in	Monitor check-ins while an event is in progress, or get an analysis of the absence rate and no-show patterns after it’s over.
event-finances	View payment status and amounts still outstanding. You can also request to see incomplete orders where someone started the purchase process but didn’t complete it.
compare-events	Compare 2–10 events side by side to analyze key metrics, or get a consolidated revenue overview across your entire organization.

All tools suggest the next action to make it easier to chain questions together in a workflow.

Examples of workflows

Check the status of an ongoing event

“How is check-in going at the Summer Party right now?”

The AI will use “find-events” to locate the event, and then “event-check-in” to retrieve real-time data.

Find participants with special needs

“Who at the Leadership Conference has reported food allergies?”

The AI uses “find-attendees” to retrieve participants with registered allergies or accessibility needs.

Compare revenue

“Compare ticket revenue from our last three events”

The AI finds the three most recent events using ` find-events ` and compares them using ` compare-events`.

Privacy and Security

• No server-side sessions —each call must include a valid Bearer token.
• Data masking by default — participant and contact data are displayed in summary format. Detailed personally identifiable information (PII) must be explicitly requested.
• Organizational isolation — you only have access to data associated with your own organization.
• Audit logging — all tool calls are logged with the tool name, organization ID, user ID, and execution time
