What is the ON24 MCP Server?

Connect your ON24 account to any AI agent and take full control of your digital event orchestration and audience engagement through natural conversation. ON24 is the leading platform for webinars and virtual environments, and this integration allows you to retrieve webinar metadata, manage attendee registrations, and analyze participation intelligence directly from your chat interface.

What you can do

  • Registrant Lifecycle Management — Enroll new attendees and monitor registration lists directly from the AI interface to track campaign reach and conversion.
  • Audience & Participation Intelligence — Access and monitor attendee analytics and elite-level engagement metadata via natural language to drive better event ROI.
  • Hub & Experience Control — List your organization's hubs and target experiences using simple AI commands to maintain a clear overview of your digital presence.
  • Operational Monitoring — Track system responses and manage survey metadata to ensure your attendee feedback loops are always optimized.

How it works

1. Subscribe to this server
2. Enter your ON24 Client ID, Access Token Key, and Access Token Secret from your integration settings
3. Start managing your virtual events from Claude, Cursor, or any MCP-compatible client

No more manual logging into dashboards to check registration counts. Your AI acts as a dedicated event manager or digital marketing coordinator.

Who is this for?

FAQ

Frequently asked questions

01

Can my AI automatically find the registration count for a specific webinar?

Yes! Use the get_webinar tool with the Event ID. Your agent will respond with complete metadata for the webinar, including total registrants and event status in seconds.

02

How do I find my ON24 Client ID and Tokens?

Log into ON24, navigate to Platform Tools > Integrations > API Tokens, and click 'Provision a New API Access Token'. You will find your Client ID, Token Key, and Token Secret there.

03

Does this work with EU data centers?

This integration currently targets the primary ON24 API (api.on24.com). For EU-hosted accounts requiring api.eu.on24.com, ensure your Client ID is associated with the global integration gateway.

04

How does Mastra AI connect to MCP servers?

Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.

05

Can Mastra agents use tools from multiple servers?

Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.

06

Does Mastra support workflow orchestration?

Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
