Can I connect Calendly to Slack for free?

Yes! 0nMCP is open source and free to use. Install it with "npx 0nmcp" and start connecting Calendly to Slack immediately. No credit card required, no trial period, no feature gates.

How long does setup take?

Under 60 seconds. Run "npx 0nmcp", provide your API keys, and describe what you want to automate in plain English. 0nMCP handles the rest -- no drag-and-drop builders, no complex configurations.

Is this better than Zapier?

0nMCP has no monthly fees, runs locally on your machine (your data never touches our servers), supports 545+ tools across 26 services, and lets you describe workflows in plain English instead of building multi-step automations by hand.

Does it work with my existing Calendly account?

Yes. 0nMCP connects to your existing Calendly account via API keys. It doesn't create separate accounts or require special permissions beyond what you already have.
