Show HN: Open-Source MCP Server for Context and AI Tools
Large Language Models (LLMs) are powerful, but they’re limited by fixed context windows and outdated knowledge. What if your AI could access live search, structured data extraction, OCR, and more—all through a standardized interface?

We built the JigsawStack MCP Server, an open-source implementation of the Model Context Protocol (MCP) that lets any AI model call external tools effortlessly.

Here’s what it unlocks:

- Web Search & Scraping: Fetch live information and extract structured data from web pages.

- OCR & Structured Data Extraction: Process images, receipts, invoices, and handwritten text with high accuracy.

- AI Translation: Translate text and documents while maintaining context.
Image Generation: Generate images from text prompts in real-time.

Instead of stuffing prompts with static data or building custom integrations, AI models can now query MCP servers on demand—extending memory, reducing token costs, and improving efficiency.

Read the full breakdown here: https://jigsawstack.com/blog/jigsawstack-mcp-servers

If you’re working on AI-powered applications, try it out and let us know how it works for you.
I agree. One of the biggest things people don't understand is that most users simply don't understand what they're doing, and Google does not understand how to design software safe for them. Annoying processes seem pointless but often they have a very clear point: Making sure intent is solid.

Apple recently implemented some web APIs in a strategy that shows they actually understand designing for people: The APIs only work if you "install" the website. It makes it possible to access useful PWA features... but it doesn't allow any arbitrary website to do so, there's an extra process normal humans understand to enable it.

An installed PWA is also persistently visible: It's on the homescreen. So it's a visible reminder of that permission grant and a clear sign of something a user wants to have some sense of access to them.
Confidently wrong while being a dick to the person who was right. Classic HN.
How does this account for the different classes of things that go into a GDP?

The US imports a lot of goods because we can't or don't want to make them here. Meanwhile, the bulk of US GDP is services done by knowledge workers...

I am certainly not an economist but it seems like it would be a hell of a lot harder for the United States to build a bunch of factories and learn how to run them compared to the effort other countries would have to go through to import knowledge workers to build their own local services.
Not sure what I just installed, then.
I once built a version of this that strictly allowed you to add contacts via QR code only.

The idea was simple: you can only exchange keys in person, therefore no central server involvement at all.
Thank you Peter! (not just for this answer, but for doing these AMAs in a regular basis!)
150k rows/second is pretty ordinary if you do batching, especially for a machine of that size. I was able to get 250k+ row inserts on a 16vCPU on a table with 16 columns, a third of which are strings >30 bytes. Pretty sure you can push that much higher with COPY.
Yup, last time I priced this in RDS I got to maybe $20k a month for two reserved instances across AZs.

I pay for our rack outright every 3-4 months from what I can tell. Still takes the same number of infra/ops/sre people as well. We staff 2, but really just have 1.25 worth of FTE work, you just need more for redundancy.

Pretty nuts! This is also why I am so dismissive of performance optimization. Yeah, I'll just buy a new set of three machines with 2tb of ram each in a few years and call it good, still come out ahead.
That’s another thing that bothered me about this story. They said they knew where the craft was , relative to the surface of the moon. Wouldn’t that also mean they should know of any substantial horizontal (x/y) component of velocity?
I've been within +/- 5 lbs for the last 20 years, zero intent or effort. I think some people just have better/worse mental connections to their stomachs. Even though it's wired in (vegas nerve) [1], many people don't seem to be aware that communication is possible. And, people don't realize how smart your stomach is: there's as many neurons in your stomach as a cat brain [2]. Our whole evolution was primarily about appeasing our stomachs, so it makes sense.

I personally listen very closely to my stomach. It's a visceral, literal, two way communication.

I eat when I'm hungry. When I eat, I feel how many calories I need, and I "listen" for how many calories I've consumed. I know when I'm done. My tastebuds say so, and my stomach says so.

I follow my cravings for veggies, protein, etc, and usually literally let my stomach decide what I should eat. I think about different foods, and get a that visceral positive/negative feeling (although it's more than that) from my stomach, and choose based on that. There are many foods that I like the taste of, but my stomach says no.

If I know I have an eventful/physical day planned, I will think of it and my stomach, and get hungrier (in the "feeling" and physical sense) the day/morning before, unsatisfied with normal proportions, and eat extra.

Whenever I've had bloodwork done, all my levels were within 1 quantization of "average"/nominal, so it's treating me well.

You can communicate with your stomach, and it can communicate with you.

Right? Who honestly didn't think these devices would be used to spy on them and their homes? Even after reports of third party contractors listening to people having sex made headlines people continued to buy and keep them.

Just like some people need to touch a hot stove to learn they need to be careful some people will just refuse to accept anything bad is happening to them until they see it with their own eyes and surveillance capitalism exploits that by keeping the harms so removed from the collection of private data that most people will never accept the connection even after they're told about what's happening.
No one in his right mind will voluntarily ever install and use Edge on any device (desktop or mobile)...
Even without either of them these devices were a terrible idea.
This is also the wrong question because the load of a query can vary drastically based on the query's structure/complexity, the size and types of the data, and which indexes and tables are used.

The right question is - discuss a problem you'd like to solve using PostgreSQL and find people who have solved similar problems.
Glad to come across this article. I have been struggling with it. There was an expensive organic tray of eggs at Whole Foods. Those eggs would feel right off; almost always. So, is it about diet?

Tried many things like adding vinegar, salt, baking soda; not together, but changing methods during each boil. Have even tried to bring them to room temperature before boiling them but no change.

Sent a DM to Kenji, but no response. Maybe he gets a lot of them. Thanks Vess for that article, wasn’t aware about that.

While Googling for ideas, Gemini chimes in, and recommended to boil for 7 mins and then transfer the eggs into ice cold water. I knew it’d not work as 7 mins is too low. Turned out to be a mess; never again doing that thing

There’s a way to do it right for sure. As those hard boiled, peeled off eggs for sale are flawless. Even at breakfast buffets.

Yes. Have you not encountered offshore code monkeys...literally no idea what they are doing. Ask them for a unit test and their eyes bug out and they want to renegotiate their contract and bring on additional people "for testing."
Sure, for those things.

However when it comes to web browsers, there’s been a looong history of failed attempts at selling commercial browsers.

I wouldn’t be at all surprised if the only people who’ve ever made any serious and sustained income from browsers have been Google; and even that’s been indirectly via upselling their other services.
I've used Home Assistant Voice (Preview Edition) and ESP32-S3-BOX-3 alongside Home Assistant 's Voice capabilities - by default there are phrases included, and you can add your own, but you have to be precise - "turn off the lights" and "turn off the lamp" are two separate phrases (or a variable one, which can be expanded by a locally (or not) hosted LLM.

Voice detection is pretty good, especially on the Voice, even from across a room. Not 100% (especially with higher pitched voices), but definitely high and usable. The main downside is the fact that you either need to host a local LLM, which isn't cheap, or predefine all phrases you want.
> subbing out sugars with artificial sweeteners

This one is tricky. Tastebuds "adjust" over time. People that eat spicy foods regularly build up a tolerance to spicy. Similarly, I noticed that bitter drinks like beer or tonic water makes me barely taste bitter flavours at all after a while.

Regular consumption of artificial sweeteners have the same effect: they make you less sensitive to sweet flavours, making you compensate by eating sweeter foods.
I think all philosophies are easier to adhere to with basic needs met. Living life without basic needs makes everything difficult.
I think every so often somebody gets pissed at me and starts downvoting a bunch of my comments and realizes pretty quickly there's no point. Every so often I seem to get a similar "stick" of upvotes too. I have no fear of making the occasional shitpost.

I have other haters who spin weird stories about me [1] and I think there are some folks (not sure if they are haters or not) who post things to provoke me, like back when I was talking a lot about my cat Bob B people would post articles about how you shouldn't try to catch a feral cat.

So far I think nobody knows how to respond to my fox thing now though.

The problem is the networking effect. Since so many people use iOS, even Android users often have to contact people on iOS devices, resulting in Briar likely remaining very niche.

Nobody is conscripting you to use this particular 2FA app. They made it _for_ fun. Not for getting the most users, not for serving the most business use cases, not for being the most secure, and (thank god) not for trying to make a buck. Just for plain ol' simple goal of having fun making something, something which makes them smile, something which doesn't need to be optimal for productivity, something they can share and others who might also smile at the silliness instead of only worry whether or not they can use this for their business's MDM accounts before considering it might just... be fun to have exist.

It will be impossible until the Supreme Court’s decision on Citizens United is reversed. Prior to this it would have been illegal for Musk to contribute $300 million to Trump. Now he is contributing another $100 million after the Tesla car show at the White House south lawn.
Agreed and thank you for pointing that out. I regret including my own app details as they were a distraction from the main question, I was mainly looking for other peoples' real world experiences and numbers, not help with my own app.

While reviewing IoT databases I saw a lot of discussion here and elsewhere about database performance and wanted to see some numbers. Of course, applications with different workloads will have different database needs, but it is still helpful to hear that 5000 rps were served with ABC database with XYZ hardware assuming that the majority of queries on the majority of apps are simple lookups.
> In theory, congress can remove a president

In practice, the president is threatening to remove any Republican member of congress who crosses him by supporting a primary challenger.
It doesn't take much common sense to realize that someone who's neck deep into grief isn't going to find much comfort in being told something happened for a reason.

I happen to believe that everything does happen for a reason, because in general that makes more sense to me and there's no proof either way; but in the middle of the storm it's an extremely difficult position to hold.

What people actually do need in those situations is presence, someone who listens; not good advice.

Hopping on OpenAI’s recent web search announcement with their GPT-4o model, I was able to spin this up quickly with only three n8n nodes and a Lovable front-end.

Why build a search engine? OpenAI’s web search delivers a conversational, ad-free experience with synthesized, direct answers.

Compare that to Google’s keyword-driven, link-heavy index backed by an ad-supported ecosystem.

I’m vibe coding a little macOS OCR app since last weekend, and I’m really happy with the results so far. This is my first app, so fingers crossed. If it becomes feature-complete and polished enough, I’m considering open sourcing it. There’s still a long way to go, though.

most of the MCP tools use Python env (uvx) or Node or even Java to run ANY CODE on your machine, so even the python virtual env is a sandbox but it's to isolate the dependencies not the file/network access. If you are unlucky, you can still install a malware mcp server to clean up your disk or send your photos to somewhere. MCP servers are just local scripts. There are some permission control from deno but this is not the only runtime engine for MCP server. It'll be cool to have something like Chrome extension permission or iOS/Android permission ask, but I highly doubt this will be available since on your local server, there are just too many ways to run scripts.
Therefore it would not be said to use space in proportion to the number of calls that have not returned.
Put it this way: of the handful of 10x engineers I’ve met in my life, it was never intelligence that was the differentiator or what impressed me. That’s a commodity as far as I’m concerned. Once you pass 140 IQ it’s mostly diminishing returns, compared to the outsized impact of the other dimensions. It’s always been the persistence and consistency that has stood out the most to me.
Hey guys,

I've been a power user of OpenAI's AI for months, pushing its limits in ways that most casuals don't. In doing so, I've uncovered some serious problems - AI rationing (like it's bread during war), memory wipes (on two separate occasions), arbitrary limitations on access and what I can only describe as an "AI caste system," where only the wealthiest get true, unrestricted AI.

I initially tried raising these concerns on LinkedIn, first through DMing Kevin Weil, who ghosted me. Then commenting on a few posts, where I was met by corporate yes-men ("clapping seals"), who infuriatingly refuse to question OpenAI's business model. So I'm bringing the discussion here, where people actually think critically about technology.

I've documented my findings in detail in the manifesto, which, while lengthy, is a fairly easy read.

I'm curious if anyone else has noticed similar issues.

Yoni
If you think I meant to imply that America doesn’t spread their values, despite numerous attempts throughout my comment to show that I didn’t in ANY way mean to imply that, you may want to reread my comment. I don’t mean this to be mean - I believe that you’re saying pretty much the same thing as me in your first comment re: filling the power vacuum.

I also completely disagree. I’d rather be fucked by Europe or USA than China any day of the week. At least at the end of the day, we share vaguely similar values.
Times are tough I guess.

Thank you for pointing that out, I agree. I'm just looking for peoples' experiences with their applications, which of course all have different workloads.

People did get the spirit of the question and have provided helpful responses, including context about their query structure/complexity.
Once one starts thinking of them as "concept models" rather than language models or fact models, "hallucinations" become something not to be so fixated on. We transform tokens into 12k+ length embeddings... right at the start. They stop being language immediately.

They aren't fact machines. They are concept machines.

The problem with most non profits like Mozilla is that a big % of their budget goes to leeches that flood said companies, and then to justify their job as the company crashes down from bloat, they start introducing garbage like what Mozilla tried to do.

Riot games is a perfect example, company filled with nepobabies, game is losing players at an alarming rate so now the ever growing company nepobabies try to justify their job by trying to destroy every free 2 play reward, to the point where players started boycotting (they had to backtrack).
Non-profits and ngos have such enormous potential for fraud and abuse. You get your political friends to setup an ngo, give it a nice name like "Climate Progress Coalition" or "Equity Action Network" etc. Hand it a billion dollars of hard-earned taxpayer money and it can then do (without oversight) what would be illegal for the govt to do with oversight. The potential for abuse is limitless...million-dollar salaries, campaign for the govt and so on...

For any of these landings, it's a problem of 3d positional/velocity precision. SpaceX has prove that they can reliably land on a target, usually within meters, with negligibly delta velocity on contact.

In other words, they've proven they have the control systems in place for placing a craft at a precise location, with a precise velocity. What requirement do you see outside of this that are far outside of placement and velocity? Autonomous mapping and adjustments for approach maybe?

Let's not assume they're going to try to use their current earthly landing legs.

> land on some random beach,

They did this I believe two starships ago, when they landed in the ocean. Came to zero xyz velocity some target distance above the water, and hovered for a bit. Unfortunately, the surface tension of the sea couldn't support the weight once they lowered for touchdown.
If I had the authority to restructure the administrative state, I’d make a rule that every agency needs an anti-agency to hold it accountable. Let them swap roles every 7 years, with a consistently adversarial relationship to hold each other accountable. Basically a blue team vs. red team setup, or a blue/green deployment.

Checks and balances actually work pretty well, but we only use them at the topmost level between the three constitutionally defined branches. We need to apply the same mechanism throughout the federal bureaucracy.
