WebMCP is currently being incubated in W3C [1], so if it lands as a proper browser standard, this becomes a endpoint every website can expose.
I think browser agents/skills+WebMCP might actually be the killer app for local-first apps [2]. Remote APIs need hand-crafted endpoints for every possible agent action. A local DB exposed via WebMCP gives the agent generic operations (query, insert, upsert, delete) it can freely compose multiple steps of read and writes, at zero latency, offline-capable. The agent operates directly on a data model rather than orchestrating UI interactions, which is what makes complex things actually reliable.
For example the user can ask "Archive all emails I haven't opened in 30 days except from these 3 senders" and the agent then locally runs the nosql query and updates.

They already need a remote API for every possible user action. MCP is just duplicate work.

llm doesn't need all these and can't parse it anyway without additional tools (e.g. why should it spend tokens even trying to convert unix timestamp to understand the time)

You can justify manifest v3 for security reasons, or you can can do this. You cannot do both without severe cognitive dissonance.

Like that stopped anyone before from just ignoring the "cognitive dissonance" and moving ahead anyways with whatever gives shareholders the most short-term profits...
Comment by SlinkyOnStairs 5 days ago
You can "hack" the agent by literally just putting some text on any website it reads. AI browsers have turned EVERY comment feature EVERYWHERE into XSS.
This is stupid but mostly benign where the AI only spits out text. It's catastrophic if the AI does anything to the webpage. (And AI firms want people to use this everywhere)
What is the future of this product supposed to be? I send a 1 dollar cent transaction to someone, with a prompt injection in the description, and their AI agent gleefully sends me a thousand bucks in return?

2) While injection has potential, this is fairly well mitigated. Look at comet and others.
These are all whataboutisms coming from a place of fear.

Comment by thedevilslawyer 5 days ago
From the article: It's a side page agent that has only access to the page, and outputs content in text only, and awaits user confirmation on actions. It's all on the page. It's I guess it's a mono-fecta?

PS: It is Gemini based, that's an LLM.

The anthropomorphization juxtaposed to the actual command is a bit ironic.

If AI can do everything and gets everyone out of jobs, who is going to consume the ‘everything’ produced by AI for someone to pay for the AI?
I don’t think UBI is a real solution, it’s too hand wavy.

Same thing that happened when automatic threshing machines replaced 80% of agricultural labour.
Comment by partyficial 6 days ago
Not everything - Many things.
Not everyone - Many ones.
The people who cannot compete fade out, and the ones that are left reap the benefit of the machines. Just like one farmer reaps the benefit of a tractor that replaced 20 laborers.
The earth population keeps reducing until it is kinda a vacation resort for 100 billionaires + others who work for them + machines.
Then some politician who promises to be a voice for the people uses force/army to kick the billionaires out, redistribute the wealth, and then the population increases and the cycle continues.
This has been happening and will continue to happen until the heat death of the universe. (and then repeat after it gets created again).

That's not even close to true. Basically every study on UBI, everywhere, has shown that either more people work, or employment stays about the same, but in each case happiness and health go up vs the control.
Since it's very clear you haven't researched your claim whatsoever - why are you making it? Why would you say something so wrong with so much confidence?

Comment by Schmerika 3 days ago
If we have the technological means and capability to reduce employment to 10% - why wouldn't we?
Is it so impossible to imagine a world where people only work when they want to? Where the jobs that "no one would do if they weren't desperate" just pay very well instead?
Also, if you really think every UBI study is fundamentally flawed, feel free to design and run your own. Until then, maybe you could do better than waving a hand and invoking a hypothesis to try and invalidate literally every study that speaks against your claim, lol.

All temporary studies are fundamentally flawed, because people act based on their permanent lifetime income. It's not like I can design it better, it's just not something that can easily be studied (on any reasonable time scale).

To engage with your question, the only way to truly, objectively ‘add value to one’s life’ is to become intimately familiar with them, their habits and everything they do on- and offline to understand what they need. This is the entire modus operandi of the current ad industry.

Completely gets rid of ads that nobody likes anyway.
You could maybe automate it say “if I spend more than 30 seconds on page, pay x credits”

The instantiation I'm working on is to track the viewer's long term goals and the habits they're trying to form, then only show ads relevant to those. Ads today are shitty because people with products that add no value to anyone's life can somewhat overcome that disadvantage by bidding more on ad space, so that's what we see. But there are plenty of products that would actually add net value which it doesn't occur to us to look for, and insofar as ads exist, they should help us find them.
This project (my working title is eudaimonia) aims to let the user essentially aikido the attention economy arms race by saying "here's what I think would add value in my life, you may pitch your product iff it's actually relevant to that".

To your third point, I don't think all tracking is created equal - if it were, there'd be no instinct to post on social media at all, but in fact privacy and publicity are complex things with overlapping sets of advantages and disadvantages. Tracking probably feels purely disadvantageous because the people doing the tracking are in thrall to "A vendors", but if the tracker is incentivised to work with "B vendors" instead it becomes a much more nuanced issue.
Comment by kuboble 6 days ago
The ads are only good in a context when I'm searching for particular product.
When I'm trying to do my work then any ad that takes my attention has negative value.
Show me the same ad when I'm actually searching for a new vacuum cleaner and we're fine.
Comment by eucyclos 5 days ago
I agree if you're in production mode, all ads are unwelcome, but most of us spend a lot of time in consumption mode too, and that's where unlooked for opportunities are really welcome. If the system could distinguish between when the user is in production vs consumption mode it would reduce friction even more over the initial vision. Not sure how to distinguish that though, most of us can't even tell it about ourselves, let alone want to tell a browser extension about it. Maybe a 'production time' setting that forces a wait time on social media sites and doesn't show replacement ads at all while on?
Comment by ButlerianJihad 6 days ago
Furthermore, it led me to muse whether "Prompt Gemini for <xxx>" was a thing that any URL could do? If I went to a random malicious website, could they prompt Gemini to do something for me? If Gemini was hooked up to my Gmail, could a malicious prompt delete all my email, and all it would take is a misclick? Chilling.

I can see the appeal of this feature and I am generally speaking an AI booster.
On the other hand...like...wat? This feature feels way too premature and risky to let loose on the public.

this is google introducing a feature that will encourage more use of a product that they charge money for. we don't need to speculate "how does this benefit google" on the products that they directly charge for.

More Google use, more data they gather, more ads they can show you

If you look at market share, Google the search product barely changed.
In terms of financials, Alphabet is earning more than ever on ads, according to earnings.

Second video seem's more real. And yeah, again not against the rules, but dropping onto website, no ads, prompting data out of it is very in the ethos of our current "lets just do an ai" to be relavent era.

The browser approach makes sense for Claude code and ChatGPT. I wonder how well it holds up once you have 50+ prompts though — finding the right one fast is the real problem for me.

> I know I wrote a good one for my git commit/push flow somewhere, but finding it when I need it usually takes longer than just rewriting it
This is actually a really good use case for a skill. Then when you go "commit and push" it'll do the right thing

- Becoming a Platform

[list continues]
There is something comforting about seeing that the SV stopped having ideas and now just recycles and recombines the same tropes over and over again.
It's still all terrible, but it's a devil you know. You can live with that. You can skip the broken stair and duck, knowing exactly when they're trying to punch you in the face again.
Now here's hoping that eventually, they get bored and just stop entirely.

Yeah, if the LLM is used for natural language translation into hard data, and not extrapolation, to me it's a very valid (and predictable) tool.
In the first case especially, i trust the LLM to translate your "flour t80 16oz" into usable data to query (without LLM) a caloric/nutrition table or something. I don't trust it to do the extrapolation correctly more than 80% of the time.
For the shopping, i would never trust a company LLM, sorry, google/amazon lied to me way to much to ever trust them.
For the third one, yeah, why not.

If instead of a copy-pasting spree, or setting up a whateverClaw, the user might just click a button in Chrome, it could be actually useful. (Consider a dozen such buttons.)

Immediately after booking something,I tell Gemini to add it to my TripIt. Works great. I have a little prompt explaining how I like it formatted that I cut and paste, so I can just make this a one-click prompt. I could also have it add flights to my.flightradar24.com.
I also use Gemini in Chrome to add appointment confirmations to my calendar. Or remember things in Google Keep.
There's lot of use cases for this kind of thing.

The script to turn the coffee maker on when dad posts on Facebook for the first time each morning that worked in 2014 won't work anymore in 2026.
Having this sort of thing built into a mainstream browser will open up a new avenue for automation, which I think will be a good thing for breaking down data silos and being good for the world overall.
