Do you respect robots.txt so administrators can block this tool?

Should I be blocked if I ask Claude Desktop to lower the prices in all of my Craigslist ads by 10%?

Do user agents doing work for users need to respect robots.txt? If yes, does chrome?

Any scraper is also a “user agent doing work for users”. Which ones should respect robots.tx?
randunel 4/8/2025||
Does the user agent fit the definition of a web crawler? If so, then observe robots.txt. This one does not, see https://en.m.wikipedia.org/wiki/Web_crawler

How does this compare to Anthropic's Computer Use?

i want to add this for my project (which use wasm) but rustlang/socket2 WASI support is not merged yet. after that rust CDP will work.

> The moment tools like socket2 or HTTP clients land with Preview2

i'm waiting for that as well. my other options are

- either bind a host function to manage wss connection to wasm. fork a CDP lib to use that.

- create a proxy between http/wss maybe. And then fork a CDP lib to use http proxy i think.

awesome! For the Cursor / React / Click to Add 2 example, can we also have it write a unit/e2e regression test?

> that's a great use case! the aria snapshot that browser mcp generates is enough to write tests for playwright using its role-based locators, but i may add a get_page_html tool in the same way that they're considering: https://github.com/microsoft/playwright-mcp/issues/103

How does it compare to playwright mcp?

works better than puppet mcp for me but having issues with keyboard events and actions on some websites.

> Private > Since automation happens locally, your browser activity stays on your device and isn't sent to remote servers.

I think this is bullshit. Isn't the dom or whatever sent to the model api?

namukang 4/7/2025|
Of course, you're sending data to the AI model, but the "private" aspect is contrasting automating using a local browser vs. automating using a remote browser.

When you automate using a remote browser, another service (not the AI model) gets all of the browsing activity and any information you send (e.g. usernames and passwords) that's required for the automation.

With Browser MCP, since you're automating locally, your sensitive data and browser activity (apart from the results of MCP tool calls that's sent to the AI model) stay on your device.

johnpaulkiser 4/7/2025||
I think we need to be very careful & intentional about the language we use with these kinds of tools, especially now that the MCP floodgates have been opened. You aren't just exposing the users browsing data to which ever model they are using, you are also exposing it any tools they may be allowing as well.

A lot of non technical people are using these tools to "vibe" their way to productivity. I would explicitly tell them that potentially "all" of their browsing data is going to be exposed to their LLM client and they need to use this at their own risk.

Can these things automatically solve recaptcha? That's the only AI browser feature that I have a real use for.
