Show HN: MCP-C – cloud platform for running MCP agents and apps
by andrew_lastmile | 2025-10-24 12:12:42+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.)

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!

I can't say as to what it might've been like 80+ years ago, but years back I was with a friend on a trip through a PX and there was a rotary display (perhaps like you might see used for postcards in other contexts) with rank insignia and other small uniform bits for fairly low prices (single-digit dollars iirc, though this was 20+ years ago). Even if they had to pay out of pocket or deal with an irritable quartermaster, the urge to give a small remember-me-by token to a friendly (and let's be honest, beautiful) face when facing down imminent chaos and barbarity is probably strong. Similarly, I recall hearing of troops throwing their coins to kids along the embarkment route in the UK as they headed to Normandy; after all, where they were going they wouldn't need them.

It’s like the entire release management was left to a couple of product and UI types . You can tell because they seem to have focused on UI eye-candy instead of UX / interaction or any meaningful QE. Like there is a glaring evidence if attention to detail in the most useless of places.

This thing is laggy…on my brand new 17 Pro. Why not just make the entire OS an electron app at this point?

The Minneapolis Fed calculated CPI levels since 1800 here. [1] In the 150 years from 1800 to 1950, the CPI never shifted more than 25 points from the starting base of 51. From 1971 to current, it increased by more than 800 points. Keep in mind all the incredible events that 1800 to 1950 covers - World Wars 1 and 2, the Civil War, Great Depression, Spanish Flu, and more. And prices always stayed extremely stable.

Then we give the government the ability to print money at their discretion and money just starts inflating endlessly to the point of having no real meaning all the while wealth inequality grows to unimaginably high levels, to the point that the richest American now has personal wealth greater than the entire GDP of America in the 50s.

So you clearly don't just inevitably end up with deflation. Before 1971 the overall economic system was quite stable. Obviously there booms and busts, but it's not like the current system has changed that. Instead we now just have constant busts which are stabilized only by the government dumping obscene amounts of money into the economy which results makes all the economic and related problems we have even worse. And it's all obviously building up to a completely catastrophic bust that'll likely make the Great Depression look like the 'good ole days.'

This part seems fairly editorial:

>Debian Policy still cites the FHS, even though the FHS has gone unmaintained for more than a decade.

What ongoing maintenance would a file system standard require? A successful standard of that type would have to remain static unless there was a serious issue to address. Regular changes are what the standard was intended to combat in the first place.

>The specification was not so much finished as abandoned after FHS 3.0 was released...

OK.

>...though there is a slow-moving effort to revive and revise the standard as FHS 4.0, it has not yet produced any results.

So it is not abandoned then. A slow moving process is exactly what you would want for the maintenance of a file system standard.

>Meanwhile, in the absence of a current standard, systemd has spun off its file-hierarchy documentation to the Linux Userspace API (UAPI) Group as a specification. LWN covered that development in August, related to Fedora's search for an FHS successor.

Ah. Systemd/Fedora want a standard that they can directly control without interference from others.

> the established politicians do not like him and did everything they could to stop him from running

Again, this is a excuse-making whopper. The republican aisle in the senate refused to convict him twice, which would have prevented him from running. I won't argue "do not like him" in the abstract, but in practice established politicians in his party are 100% behind the guy.

RMS is functionally irrelevant to the experience of someone on a Mac who wants to use emacs, because -- Again! -- all you have to do is download a build and you're off to the races.

That's the end of the discussion. It doesn't matter what RMS' position is. (And yes, I know what those are -- and no, I've never spoken to him, because I tend to avoid creeps.)

emacs is free software that, once released to the world, will find its way into many places perhaps its most famous proponent would prefer it not. And this happens because his opinion is irrelevant. This has happened before. This will happen again. RMS being a sad puppy about Macs and Windows doesn't change the fact that many, many folks have productive emacs-centered computing experiences on those platforms. He can die mad about it.

You posted a shitton of material, but none of it addressed the simple fact that using emacs on a Mac is approximately as easy as using it on (e.g.) Debian. There's no real difference for most use cases.

I'm not in the habit of taking homework from gish-galloping boomers hell bent on missing the point, so I'm not going to answer any of your questions. I will, however, note that I'm far from the only person in this thread looking at you and thinking "what the hell is this guy on about?"

I don't think its the same thing as whats described in the article.

When i talk with someone very aligned with my thinking and knowledge (fellow it collegues/friends with simiiliar skill level) we do not a lot of words to be aligned and convey complex thoughts.

We reference and use words which we both know, we read and reference similiar news stories etc.

But the way they describe it with colors, vibrations etc. is probably somethig you can't just convey.

Airline safety is a special case I think — THE NTSB does incredible work, and their recommendations are always designed to improve total safety, not just reduce the likelihood of a specific failure.

But I can think of lots of examples where the response to an unfortunate, but very rare, incident can make us less safe overall. The response to rare vaccine side effects comes immediately to mind.

FP is an interesting language. In my opinion, it is somewhat problematic that different language concepts (Delphi, etc.) have been more or less merged into FP, resulting in redundant object models, for example. Pascal as a language also has various historical legacy issues (dangling else, block overhead, global namespace, etc.), which Wirth corrected in Modula and Oberon. The compiler is huge and apparently difficult to maintain (see e.g. https://github.com/rochus-keller/freepascal/). The resulting, optimized x86 code achieves about 70% of GCC compiled C code (see e.g. https://forum.lazarus.freepascal.org/index.php?topic=64261.0), and it turned out that desctructors and some built-in data structures are extremely slow. So I went on to implement my own Pascal/Oberon descendant (see https://github.com/rochus-keller/micron/, work in progress).

I really hope you lock it down to something like Tailscale so that you have a private area network and your Samba share isn’t open to the entire world.

Samba is a complicated piece of software built around protocols from the 90s. It’s designed around the old idea of physical network security where it’s isolated on a LAN and has a long long history of serious critical security vulnerabilities (eg here’s an RCE from this month https://cybersecuritynews.com/critical-samba-rce-vulnerabili...).

It’s hard to express how frustrating it is to try to allow kids access to tech and the Web (it’s kind of important that they have at least some access! And isn’t a bunch of this allegedly for super-charging learning and exploration of the world?) while basically every platform and vendor (of most any kind) except Apple’s and Nintendo’s stuff is somewhere between mediocre and annoying, and utter shit on this front (even, and in some ways especially, open source operating systems) and none of these goddamn things coordinate or communicate with one another (and of course SSO, basically a necessity for even starting to tackle that kind of problem, is an “enterprise” feature for almost every vendor)

Then we’re told this is all our fault. Meanwhile schools send home devices that don’t lock or at least disable Web access at night, and I can’t admin those to fix that dumbfuck oversight. To point out just one of many ways we get undermined. This is a whole bunch of stress and work that simply did not used to exist for parents and I absolutely get why a lot just stop trying.

I love the feeling that I own my computer again, thanks Asahi team. But I am so attached to my MBP M1 and remix 42, that I was kinda hoping that this was the final release at the end of the universe, maybe with small patches for the remaining bug-blatterings. It certainly feels like I could call this 'my last computer', and if not, then my next computer will be an M2 running Asahi.

Anyway, keep up the good work. I am currently bashing out some bare-metal Zig and assembly for PinePhone, so I get a small taste for the challenges you face, although I have some documentation. How you manage without that I have no idea, incredible work!

One thing I have been wondering is that with your approach, is it possible to run a Asahi VM inside Asahi? It would be really nice to be able to have sandboxes for all these misbehaving modern apps like browsers etc. I got the impression from earlier posts (is it muvm doing this?), that things like the GPU pass-though dont affect performance much, so it sounds like a sandbox VM approach could be very performant and powerful. Indeed, these days I run run every 3rd party app in a sandbox if possible.

Or Debian and Redhat, which have the added bonus of being "boring technology."

If you have a problem with them, 20 other people have had that same problem before you did, two of them have posted on Stackoverflow and one wrote a blog post.

OpenBSD and Illumos may be cool, but you really need to know what you're doing to use them.

…over a road of bones? Is that your image?

I'm not scared for me, but I'm definitely worried for some of you. You seem weirdly trusting. What if the thing you're counting on is really not all you think it is? So far I'm about as impressed as I am of the spam in my inbox.

There sure is a lot of it, but the best it can do is fool me into evaluating it like it's a real communication or interaction, only to bounce off the basic hollowness of what's offered. What I'm trying to do it doesn't _do_… I've got stuff that does, for instance leaning into the genetic algorithm, but even then dealing with optimizing fitness functions is very much on me (and is going well, thanks for asking).

Why should I care if AI is marching if it's marching in circles, into a wall, or off a cliff? Maybe what you're trying to do is simply not very good or interesting. It'd be nice if my work could get away with such hollow, empty results but then I wouldn't be interested in it either…

This looks great.

I do yearn for a day though when we're using something like Marimo over Jupyter as a default for these kinds of things. Particularly in GIS where there's more utility in being able to use a notebook-like interface for an executable routine (rather than an analysis or experiment, which is (and should probably remain) the primary use case for Jupyter).

"AI is tearing my company apart, what should I do?"

Step 1: Take a machete and tear it yourself.

Step 2: Pretend nothing is being teared apart.

Step 3: Go megalomaniacal.

Sounds very solid. /s

> "This is not like giving accountants calculators or bankers Excel or designers Photoshop."

Wait, it's not? Weird. It seems to be advertised exactly like it is. /s

> "your humans are liberated to do what they're amazing at: judgment, strategy, creativity"

Replace "endless delegating meetings" for "too many hands at the helm", won't work.

You can't just let people freestyle without guiding them (instead of ordering them, which is different). It's desperate wishful thinking.

There are large, mostly flat structures of highly skilled individual workers. Such as the free software movement.

There's a lot to learn from these kinds of structures. And yes, your product will become a "Linux that has no standard GUI implementation", that's what happens. But look how it goes, it's thriving.

I think some of the modern iPhone cameras use SLVS, so non-iPhone Apple Silicon might have a way of connecting to that natively too. Good luck using that though.

Without a native connection option, what remains to you is probably an FPGA converter (to MIPI CSI-2 D-PHY), which is going to be expensive of course. But still not as expensive as the sensor itself and the associated optics.

> CPI levels since 1800 here. [1] In the 150 years from 1800 to 1950, the CPI never shifted more than 25 points from the starting base of 51.

Yes and there were extreme swings in between. Predictable 2% inflation is better for the economy than unpredictable up and down jumps in prices of 10-20% over a decade or two.

> Keep in mind all the incredible events that 1800 to 1950 covers

You haven’t actually looked at actual charts or yearly figures have you? It was a roller coaster.

I certainly agree about your points on inequality etc. but Fiat money is not the cause of that itself. Monetary and fiscal policy failures are.

> Before 1971 the overall economic system was quite stable

Yes, for several decades. After the roller coaster of ~1770 to ~1950.
Show HN: A fast, privacy-first image converter that runs in browser
by wainguo | 2025-10-24 12:21:55+00:00
Hey HN

I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions.

So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy.

What it does

Convert images between JPG, PNG, WebP

Works offline once loaded (PWA support)

How it works

It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices.

Why I built it

I wanted an instant, no-ads, privacy-safe way to handle images for my personal projects — something lightweight enough to replace desktop tools.

Try it

https://imageconverter.dev

Would love feedback from the community — especially on:

Performance on different browsers/devices

Thanks for reading!
Show HN: Worthunt – a single workspace for freelancers, creators, and agencies
by Abhijeetp_Singh | 2025-10-24 12:22:01+00:00
Hi HN, I’m building Worthunt, a unified workspace for digital professionals

Today, independent professionals use scattered tools for payments, clients, analytics, and workflow. It’s expensive, fragmented, and hard to track what’s actually driving growth. Worthunt simplifies this by combining everything into one platform your network, payments, analytics, and AI insights built for the modern working economy.

Our vision is to help every digital professional operate frictionless we want to be the salesforce or Microsoft for this new digital first workforce: own their data, understand their metrics, and grow faster without relying on multiple platforms or marketplaces.

We’re partnering with teams like Framer and Lovable to integrate creative and workflow tools directly. Our target is to save users ~30% on costs and 4–5 hours a week from reduced tool-switching.

You can try it at worthunt.com Would love feedback on usability, workflow logic, or integrations you’d like to see.

I had two yellowjacket nests in the wood siding of my house this summer. Several cans of foaming spray had no effect since it couldn't penetrate far enough inside. I found a random forum thread where someone suggested using Sevin insecticide powder on the openings. It took a week and a half of daily applications using a paintbrush, but it seemed to be effective. Less expensive than calling an exterminator, and I have most of the can of powder left for next time.

I'm currently running PostgreSQL in docker containers using bitnami/postgresql:17.6.0-debian-12-r4. As I understand it, Bitnami is no longer supporting or updating their Docker containers. Any recommendations on a upgrade path to PostgreSQL 18 in Docker?

A quick glance of swapping to the official postgres container shows POSTGRESQL_DATABASE is renamed to POSTGRESQL_DB. The other issue is the volume mount path is currently /bitnami/postgresql.

Did you read the same article?

* Their is an option for the old behavior. * It is a security issue and better solutions to replace exist. * FHS isn't maintained.

I think everyone involved would prefer updates to the applications, which fix the issue. Debian opted - for now - for reliability for its users, which fits in their mission statement. On Arch /run/lock is only writeable for the superusers, which improves security. As user I value reliability and security and that legacy tools remain usable (sometimes by default, sometimes by a switch).

If you ever go outside of the US it is shocking how much other countries do with so little. Countires with a tenth of our population and an even smaller fraction of our GDP have cheap, efficient, high quality health care systems and clean, convenient public transportation. They have well equipped classrooms with teachers who don't have to work two jobs to get by. They have highly skilled police forces whose training is measured in years, not weeks. These countries are not perfect, but they seem to govern far nore effectively than the richest country on that planet. I'm not even talking about an idealized Europe; some southeast asian countries are like this too.

So yeah, where is the money going? When you combine state, local, and federal, the US spend nearly a trillion dollars a year on education (more than our military!) but where does it go? We regularly churn out illiterate graduates and teachers have to commute from another state away in order to find somewhere affordable to live. We spend more money per capita on healthcare than anyone else in the world for worse coverage and worse outcomes.

I hypothesize that the dollar's status as the world reserve currency is actually a bad thing. It makes it cheap for us to borrow money and as a result encourages all kinds of social pathologies associated with ZIRP

I'm unironically convinced that a basic Samba share with Active Directory ACLs is actually probably the best possible storage system...but the UI for managing permissions sucks, and most people don't have enough access to set it up the way they want.

Like broadly, for all configuration Hashicorp Vault makes you do, you can achieve a much more useful set of permissions with a Samba fileshare and ACLs (certainly it makes it easy to grant targeted access to specific resources - and with IIS and Kerberos you even have an HTTP API).

> Nobody wants a 20s boot every time you want to take a picture

But that's less due to the RPi and more due to lots of amateur projects that ship the RPi with a desktop Linux distribution like Raspbian (itself based on a very conservative one - Debian - that loves preserving decades of legacy crap).

You can absolutely get quick boot times on an RPi (or on an x86 machine for that matter, although you are limited by the time the firmware itself takes to boot) if you build your own read-only image with Buildroot/Yocto like any embedded shop would.

But I agree with the rest of the comment - an RPi is a terrible device for this (and for most purposes besides prototyping in fact). But not because of boot time reasons.

In this day and age, that feels like something that is true in principle but not in reality. For food, the grocery store shelves are almost entirely stocked with brands owned by 10 companies, that have a combined revenue of $375 billion a year [1]. If you have a bad experience with DiGiorno pizza and boycott them, would you know you also needed to boycott Tombstone Pizza, California Pizza Kitchen, Cheerios, Tidy Cat, and on and on. If you wanted to actually boycott Nestle, how difficult would it be to maintain a spreadsheet of the literal thousands of brands they own [2]? Any issue with any brand is just absorbed by a thousand others. Any regional effort is absorbed by their global market. It isn't the USSR, but the idea that consumers can vote with their wallet just isn't the reality we live in anymore.
