Yea it can be, but you will pay Anthropic API price. If you already use Claude code on a subscription then you can reuse your subscription for this MCP, making it effectively free

I meant why I can't use with OpenaI, DeepSeek, ... etc. Why you're limiting it to Claude?

Oh, I just picked Anthropic’s Sonnet4 to start because it’s really good at agentic stuff and because of the subscription benefits.

I will add more model support soon - any models you particularly want to see?

I’m also hoping to test out RL on the tools to get a fine-tuned model specifically for browser automation eventually.

OpenAI models and DeepSeek, that would be great

It also has its own cli if you just want to run it alone too
