Show HN: MCP-C – cloud platform for running MCP agents and apps
by andrew_lastmile | 2025-10-28 17:25:38+00:00
Hello HN!

Earlier this year, we shared mcp-agent (https://github.com/lastmile-ai/mcp-agent) [1][2], a lightweight framework for building agents with MCP. Since then we have tried to push the protocol to the limits, including hosting agents as long-running tools on MCP [3], and seen other creative approaches surface (mcp-ui, chatgpt apps sdk).

Today, we are launching mcp-c – a cloud platform designed for hosting any kind of MCP server, including agents, ChatGPT apps, etc. We are in open beta and free to use, and would love your feedback.

Here are some key choices we made:

1) Everything is MCP - Each application is deployed as a remote SSE endpoint, and implements the full MCP spec, including advanced features like elicitation, sampling, notifications and logging.

2) Durable execution via Temporal - We use Temporal as the runtime environment, allowing you to run long-running operations. This is especially critical for agents, which need to pause/resume, be fault-tolerant, and run for a long time.

3) Local to Cloud - we're fans of how easy it is to deploy a Next.js app to Vercel, so we've made it simple to take your local mcp-agent, mcp server, OpenAI app, etc. and deploy it to the cloud. We have several examples and even a handy CLI to get started quickly [4].

It's as simple as:

- uvx mcp-agent init

- uv init

- uv add "mcp-agent[openai]"

- uvx mcp-agent login

# add your openai key to mcp_agent.secrets.yaml

- uvx mcp-agent deploy

You can also try out these hosted mcp servers to get an idea. These can be connected to any MCP client (ChatGPT, Claude Desktop/Code, Cursor, etc.)

OpenAI Pizza App - https://18t536mliucyeuhkkcnjdavxtyg66pgl.deployments.mcp-age...

Basic Agent Server - https://1m82g32x8nkoppinayx0k5ye12oar6vk.deployments.mcp-age...

The HN community has been a big part of mcp-agent's growth, and we're super excited to share this with you as well. We would love to hear your thoughts and feedback!

Thanks for the links to those people. The GF(2) simplifies Grobner bases calculations a lot, IMHO, but I don't have much experience with them either. I am just curious, because to me it now seems to be an obvious way to go. I mean, the fact that we can represent any SAT problem as an intersection of 2SAT and XORSAT problems indicates, there must be some generalization of the both polynomial algorithms. And it seems to me this generalization is somehow related to Grobner bases methods.

I have only very quickly skimmed it, but I wouldn't be surprised if the theorem D.21 in Kaufman's thesis (https://danielakaufmann.at/wp-content/uploads/2020/11/Kaufma...) turned out to be true for all the unsatisfiability PAC proofs, not just the circuits she is looking at. (As I commented below. If you're proving contradiction, looking for element 1 in the ideal using Grobner basis, then it seems somewhat unreasonable to require degree of basis polynomials larger than 3, if you start from all polynomials with degree less or equal than 2. If you look what e.g. 2SAT algorithm is doing algebraically, it only needs degree 3 polynomials as well, although the monomial of degree 3 is immediately eliminated. So if the Grobner basis algorithm needs to build large degree polynomials, because no small degree will help you, it's likely your system is already satisfiable. Would really like to see a counterexample.)

> And most of that money wasn't actually money, it was free infrastructure.

But everyone who chipped in $$$ is counting against these top line figures, as stock prices are based on $$$ specifically.

> but my uneducated brain (while trying to make a point) would say it is 20% of the stated value of the investments

An 80% drop in valuations as people snap back to reality would be devastating to the market. But that's the implication of your line here.

I'm reasonably certain that I am about as old if not slightly older than the invention of in-ear headphones. I'm also reasonably certain that I have always used "headphones" to refer to any small portable speaker designed to inject sound directly into the ears. I'm absolutely certain I have never used the term "earphones", although "ear buds" was/is a common synonym for in-ear headphones.

Well there is if you go far enough. It's just the question when did they split off from each other. However there is no question that Baltic and Slavic are more closely related to each other than any other non extinct Indo-European languages.

The fact they they are the closest surviving relatives on it own doesn't mean it makes sense to group them together (i.e. Italo-Celtic is also a theorized subgroup in a similar way but nobody is disputing that Celtic and Italic languages evolved into distinct groups).

Then there is a huge amount of missing links and unknown unknowns. e.g. Thracian and Dacian probably were also pretty close to Baltic or Slavic (maybe even closer to Baltic than Slavic is but we don't know enough about them to make any conclusive claims at all... but we at least know these languages existed)

I think the argument is that it’s criminal to take advantage of the patient without insurance and ask them to ruin their life trying to come up with 195k when your system is setup to reasonably profit off the 37k you get from the insured patients. I firmly believe that even in a capitalist society the idea of profiting off of anything let alone healthcare in the thousands of percentage points is criminal.

Since we don't have an authoritative definition of what it means that companies will agree to, and tests like the turing test that must be passed in order to be considered AGI, I don't think we're anywhere near what we all in our brains think AGI is or could be. On the other hand, AI fatigue will continue until the next big thing takes the spotlight from AI for a while, until we reach true AGI (whatever that is).

I disagree that people are less weird and deviant today. I believe they’re less weird offline, because weirdness is easier, safer, and less embarrassing to express online.

I also disagree that online has become less weird. It’s less weird proportionally, because the internet used to consist of mostly weird people, then normal people joined. Big companies are less weird because they used to cater to weird people (those online), now they cater to normal people. But there are still plenty of weird people, websites, and companies.

Culture is still constantly changing, and what is “weird” if not “different”? Ideas that used to be unpopular and niche have become mainstream, ex. 4chan, gmod (Skibidi Toilet), and Twitch streamers. I’m sure ideas that are unpopular and niche today will be mainstream tomorrow. I predict that within the next 10 years, mainstream companies will change their brands again to embrace a new fad; albeit all similarly, but niche groups will also change differently and re-organize.

(And if online becomes less anonymous and more restrictive, people will become weirder under their real ID or in real life.)

Do Editorial and Opinion sections of news papers do "conflict of interest" disclosures as a matter of course? It seems like it should be assumed that an Opinion article is expressly a biased article, written by someone with an interest in the topic at hand. If the NY Times wrote an editorial on schools or on medicaid, I wouldn't really expect to see a line disclosing the number of editorial staff members with children in the school systems or with family members receiving medicaid.

And this is an honest question, I don't know what the WP standard for their Editorial and Opinion pages were prior to Bezos' ownership, nor what the broader industry standard was before say 2016.

The owner of the employer company just experienced a vacation in space, renting an entire European country for a wedding, etc.

Some employees are going to experience losing their housing. Losing their health benefits while sick. Children will be moved from their friends/schools. Some will lose their careers as they won't find new related work quick enough and will have to take whatever they can get for their next job.

While the owner vacations in space for fun.

> The seven largest U.S. tech companies (...) are 20 times bigger than Europe’s seven largest, and generate 10 times more revenue.

I'm going to guess that this part is intentional. Europe tends to be more aggressive in enforcing antitrust laws. Economically, Europe's goal isn't to have the biggest companies but to have more smaller companies.

So you're not going to get companies like Google, but you will get companies like Proton, Spotify, Tuta, Hetzner, Mistral, Threema, Filen, Babbel, Nextcloud, CryptPad, DeepL, Vivaldi, and so on.

There are very much two views of what America should be like and pretending there isn’t is why Democrats keep losing.

40% of Americans cheer how the current administration treats immigrants, non straight people, etc and continue defend the words of a racist podcaster. They wouldn’t want a “nuclear” bomb because it affects them. But there was no real fallout politically for the police MOVE bombing.

If you don’t think this country is divided, you haven’t been looking at where this country is and it’s view on reality.

Those yokels on January 6th tried. But do you think they could have overcome even the local SWAT let alone the military? There have been yokels running around for decades trying. Heck an entire Confedrrsre army couldn’t defeat the US government backed by the states

aren't programming languages like SQL designed to strike a quasi-optimal balance between precision and economy? that is to say, if I want to use plain English to specify some kind of data operations, the prompt will necessarily be more verbose and/or less specific than SQL statements. So why not just learn SQL properly? And then learn the domain-specific considerations of the source data as well as the domain-specific business requirements? Or am I missing something essential?

A few other interesting links with Vitamin D absorption. Surprised nobody has brought up gut dysbiosis and the role microbiome plays in Vitamin absorption. I'm finding it increasingly difficult to discern whether the things we consume are for the direct benefit of our cells and metabolic needs or via a more indirect path if the things we consume directly affect the microbiome within us which then translates into either nourishment or inflammation within us. Since microbiomes can change rapidly in composition, this feels like a game of nurturing over the long-haul with some minor blips along the way.

Yeah I would be willing to bet serious money that this is a few kids and that the number is not even greater than a fractional fraction of a percent.

You're seeing point wise incidents, chosen to generate outrage, and trying to apply them like all kids are doing these things, which per all trends they are not.

Sorry some fraction of people will always be stupid, we shouldn't apply constraints on the many to save the few stupid ones.

Never pay the first hospital bill if it's a non-trivial amount and you've waited a few months to get all the bills. 100% of time there is an error, mis-code, up-code, outright fabrication, etc. In California you cannot be taken to collections for less than $500 and they have to wait at least 180 days. If insurance denies a claim, you can ask for an internal appeal and then ask an independent medical review(IMR) (always do this, the internal appeal never works). With today's context windows, you can shove the whole insurance coverage booklet into the LLM and have it draft everything.

I've had $10k+ bills brought down to $200. $2k+ tests re-coded and fully covered, etc.

There is definitely a business in a LLM-powered medical billing agent that could handle this end to end (esp, contacting hospitals/insurance, waiting on hold, etc).

> Hard to believe you say we aren't subject to rationing when pre-authorization is as big as it is.

If you want to see true rationing, look to the UK (especially) or Canada (less so) where I know plenty of people who have to wait over a year to see a specialist even after doctor referral.

Meanwhile, my parents in the US at a hospital get a CT scan, MRI 'just in case' immediately (or close-to for the MRI) and pay nothing for it.
by alistairSH | 2025-10-28 17:28:28+00:00
That was an overly simplistic response. We do have credit scores in the US, and defaulting on medical bills can (but doesn't always) impact someone's score.

Without a high score, you don't get the best interest rates on loans. Or, might not be eligible for a security clearance (government work) or jobs in some industries (banking and other "high trust" fields). Or might not be able to rent an apartment.

But, the other response wasn't incorrect. We don't have debtors prisons (unless the debt is owed to the government, then they might be able to jail you).

I was put on prescription vitamin D2 50000 IU and it caused a bunch of side effects for me including heart palpitations for over a week and then a paradoxical reaction to magnesium causing them to be even more intense.

Proceed with caution and listen to your body. Doctors were accusing every other thing than accepting whatever it did to my calcium / other electrolytes bothered my heart.

It's just the internet.

Lots of deviant communities that are still quite active if you turn off your laptop/phone and go seek out the eccentric folks in the real world.

The internet has pushed towards homogeneity over the last couple decades. If you're confusing internet with the real world constantly (i.e. staying "plugged in"), its easy to come to the article's conclusion. But, you can always choose to just "turn it off".
by datameta | 2025-10-28 17:29:26+00:00
I'd also argue the culture of "digital degeneracy" has permeated the internet and is no longer locked away in, say, the bastion of mid/late 2000s 4chan. What used to be violent NSFL liveleaks content is now easily accesible by anyone with a phone. Softcore content is completely widespread on "clean" apps like IG and Tiktok.

If we measure deviance only by the metrics that existed before social media, we will of course find what is expected.

You might also find the work of David I. Spivak (no relation to the _Calculus on Manifolds_ Spivak) helpful in this endeavor.

John Baez (who is distantly related to Joan Baez, if memory serves) has also written a lot of introductory category theory and applied category theory.

I started using this and overall quite good but with very minor caveats...

* My part of the world is not adjacent to Germany (where this paid offering is hosted)...so there is a little latency. But not nearly as bad as I expected.

* While file sharing and syncing and other basic stuff is included, the equivalent of online collabora (or whatever the online office suite is called) is not included and you would have to self host it...but hetzner state this in their relevant knowledge base webpages.

You think the police are bad, just wait until all the other enforcers get their grubby mitts on this.

At least with the police you have rights. When the building inspector gets to rifle through the Home Depot camera records for the plate number of everyone who DIY'd an un-permitted shower renovation or the conservation commission asks Flock for every address the Sunbelt Rentals truck went you have no rights.

I agree with you that the Grokipedia article is better here, though I guess I disagree that the wikipedia lead has "no neutrality" and is a "straight up ideological attack."

Having read both articles (and knowing very little about this topic before), I came away with the firm conclusion that acupuncture is psuedoscience; both articles clearly explain that is not based on scientific principles and its practice is not governed by scientific methods. There was no disagreement between the articles on this point. That many in medicine describe it as quackery is a relevant observation.

It is interesting that needling as a therapy does seem to have some efficacy over placebo in trials, but both articles agree that the current body of evidence is weak with a lack of methodological rigor and very small effect sizes. But I should note that both articles describe acupuncture as being more than just a specific type of needle based therapy. They describe it as an entire system of medicine based on "qi" and the "meridians" of the body, concepts for which there is no scientific evidence. So I think describing acupuncture as "pseudoscience" is accurate.

Anyway, I thought the Grokipedia article was quite good, but also didn't find the Wikipedia article to be particularly biased.

I have an issue with the claim that the culture is stagnating. One of the arguments is this:

> fewer and fewer of the artists and franchises own more and more of the market. Before 2000, for instance, only about 25% of top-grossing movies were prequels, sequels, spinoffs, etc. Now it’s 75%.

I think the explanation isn't a decrease in creativity as much as the fact that in the 1980s, there just weren't that many films you could make a sequel of. It's a relatively young industry. There are more films made today because the technology has gotten more accessible. The average film is probably fairly bland, but there are more weird outliers too.

The same goes for the "the internet isn't as interesting as it used to be" - there's more interesting content than before, but the volume of non-interesting stuff has grown much faster. It's now a commerce platform, not a research thing. But that doesn't mean that people aren't using the medium in creative ways.

While you're not wrong that most "justice" processes are expensive, I think the parent-poster is referring to a different kind of "government inefficiency", things like:

1. Single-payer health insurance.

2. Laws that insurance-companies must actually use X% of their premiums on payouts.

3. Laws requiring disclosure of negotiated prices, to encourage competition via free-market forces.

> The original 2003 DDD book is very 2003 in that it is mired in object orientation to the point of frequently referencing object databases¹ as a state-of-the-art storage layer.

Irrelevant, as a) that's just your own personal and very subjective opinion, b) DDD is extensively documented as the one true way to write "good code", which means that by posting your comment you are unwittingly proving the point.

> However, the underlying ideas are not strongly married to object orientation and they fit quite nicely in a functional paradigm.

"Underlying ideas" means cherry-picking opinions that suit your fancy while ignoring those that don't.

The criticism on anemic domain models, which are elevated to the status of anti-pattern, is more than enough to reject any claim on how functional programming is compatible with DDD.

And that's perfectly fine. Not being DDD is not a flaw or a problem. It just means it's something other than DDD.

But the point that this proves is that there is no one true way of producing "good code". There is no single recipe. Anyone who makes this sort of claim is either both very naive and clueless, or is invested in enforcing personal tastes and opinions as laws of nature.

Hey folks, Sarmad from the LastMile team here that built MCP-c and mcp-agent.

We're looking for thoughts and feedback so will be happy to take any questions here! And as the post shows, it's really easy to try this out -- would be grateful for you to try deploying an agent as an MCP server and get your impressions!

This isn’t true and hasn’t been true fifty years ago either. A handful of the most well-known books regarding getting wealthy and having a high status were written almost a century ago. The practice of wealth accumulation was already established by anyone who was above room temperature IQ for as long as we have existed.

Deviance is all around, the author is too trapped in a bubble to see it.

It doesn’t say if that is going away. The message calls out another part as sticking around:

> Beyond this timeframe, we will keep a subset of Rosetta functionality aimed at supporting older unmaintained gaming titles, that rely on Intel-based frameworks.

Since the Linux version of Rosetta requires even less from the host OS, I would expect it to stay around even longer.

> If you make a website using HOPL software, you are not breaking the license of the software if an AI bot scrapes it. The AI bot is in violation of your terms of service.

Assuming a standard website without a signup wall, this seems like a legally dubious assertion to me.

At what point did the AI bot accept those terms and conditions, exactly? As a non-natural person, is it even able to accept?

If you're claiming that the natural person responsible for the bot is responsible, at what point did you notify them about your terms and conditions and give them the opportunity to accept or decline?

I kinda like the approach Github does: they just publish their fingerprints here: https://docs.github.com/en/authentication/keeping-your-accou...

This is served over TLS, so it's no worse than TLS. You can also benefit from the paved road that LetsEncrypt has provided. It might not be as smooth as SSH CAs once they're set up, but setting those up and the Day 2 operations involved isn't nearly as straightforward.

Is that them or is that content and algorithms seeping into every possible nook and cranny of the human experience? Creators seeking to tap value off of popular brands and fans trying to find more content and falling into a long tail?

We're making more content, taking up more time, resulting in people who are stimulated all the time. Busy all the time.

That answers the question of whether or not it was satire.

> s lost when ignorantly amplifying misquotes

Just barely squeezed that ad hominem in, with some plausible deniability. Nice.

In any case - I suppose it could, if one misquoted. Fortunately for me, was intentional as my version seems to reflect the gist of what you're saying: we (the people) shouldn't enforce the law when it comes to the actions of the leaders we elect.
