Events and groups
Create, inspect, update, list, and remove managed events and event groups.
Model Context Protocol
Connect an MCP-compatible assistant to Add to Calendar PRO. It can answer product questions from the complete documentation and maintain events, templates, registrations, analytics, and automations through the API.
What an agent can do
Create, inspect, update, list, and remove managed events and event groups.
Manage styles, landing pages, images, RSVP templates, CTA templates, and email-template references.
Read views, calendar saves, RSVP statistics and answers, custom domains, and generated ICS content.
Create and maintain webhooks or use the API tools inside a broader agent-driven workflow.
Bring your own key
The MCP server does not hold a shared master credential. Each user decides what an agent may access with an individual Add to Calendar PRO API key.
In the app, open Organization settings, Technical, then API Keys. Choose Read & Write if the agent should create or change resources; a Read key is enough for inspection.
Use the endpoint shown above and put the API key directly in the Authorization header.
Ask the agent to inspect, create, update, or analyze your event workflow. Confirm destructive actions before letting the agent execute them.
Generic client example
{
"mcpServers": {
"add-to-calendar-pro": {
"url": "https://add-to-calendar-pro.com/mcp",
"headers": {
"Authorization": "YOUR_API_KEY"
}
}
}
}Create a scoped API key, add the endpoint, and start with a read-only request.
