I just don't get why would you would want an agent to use the browser to do these mundane things (check email, work with calendar etc), when you can simply give it a few tools, and save maybe six gazillion tokens per task?
Using existing enterprise apps probably - this solution is scalable for the vendor and it's easier to sell using existing software as-is than to start out by writing new custom tools.
After doing few experiments, I think that having Agents work on browser for all tasks wouldn't be best due to many factors like token cost, safety, etc. But browser/computer can be a tool that the agent can be alongside MCPs to complete tasks that requires interaction with such modalities.
Yes, I can see the usecase for legacy desktop apps etc, but the web? it's a DOM. WebMCP coming now too, no need for screenshotting or DOM querying then either..
