Learn how to connect ON24 to CrewAI and start using 12 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
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
- Webinar & Event Orchestration — List all managed webinars and retrieve detailed event metadata programmatically to ensure your digital marketing calendar is always synchronized.
- 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?
- Event Marketers — quickly retrieve registration summaries and monitor attendee engagement without switching apps.
- Demand Generation Teams — automate the retrieval of lead metadata and track conversion from digital events via natural conversation.
- Developers — integrate real-time webinar data and attendee analytics directly within the chat.

Why CrewAI?
When paired with CrewAI, ON24 becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call ON24 tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports
ON24 in CrewAI
ON24 and 3,400+ other MCP servers. One platform. One governance layer.
Teams that connect ON24 to CrewAI through Vinkius don't need to source, host, or maintain individual MCP servers. Every tool call runs inside a hardened runtime with credential isolation, DLP, and a signed audit chain.

Why teams choose Vinkius for ON24 in CrewAI
The ON24 MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 12 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in CrewAI only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
ON24 for CrewAI
Every tool call from CrewAI to the ON24 MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
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.
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.
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.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
