WebMCP is a free, open-source experimental tool for developers to make websites AI-agent aware, ideal for prototyping. Choose Presto if you run a drive-thru chain; choose WebMCP if you want to surface your website data to LLM agents.
Can Presto Voice be used for non-drive-thru restaurants?
Presto Voice is built for drive-thru automation and phone ordering; it's not designed for dine-in or delivery-only operations.
Is WebMCP production-ready?
WebMCP is open-source and works in production for low-traffic sites, but lacks enterprise features like scalability, authentication beyond tokens, or support. Its strength is prototyping.
What does Presto Voice cost?
Pricing requires a sales call; it's tailored to location count, deployment complexity, and desired features. There's no self-service option.

Can WebMCP be customized to match my site's look?

Which industries benefit from Presto Voice?

Does the latest WebMCP Registry change its capabilities?
The Registry (Jun 2026) is a public index for sharing tool contracts, making it easier to discover and reuse integrations, but doesn't alter the core widget function.
