A playright-mcp server, or any bidi browser automation, should be equally capable of discovering/injecting and calling the same client JS exposed MCP-B site API?

It's like an OpenAPI definition but for JS/MCP? (outside of the extension to interact with that definition)

Sure they can inject clients, but that's really only beneficials for developers. doing it via browser extension means regular people can use it.

Sortof. It's a true MCP server which you can use to expose existing (or new functionality on your webapp to the client)
