so i kept noticing Claude is amazing at reasoning but quietly wrong at little deterministic things. arithmetic on big numbers, timezone math, reading a PDF it cant open, generating a QR code, hashing a password. stuff where you want the exact answer, not a confident guess.

so i built an MCP server that just hands those jobs to real functions. its called toolbox-mcp, 35 tools, all running locally on your machine. no network, nothing leaves your computer.

some of the tools:

• read the text out of a PDF so Claude can actually read the document
• exact math and unit conversions (90 km/h to m/s, that kind of thing)
• timezone conversion with real IANA zones
• image convert / resize / compress / crop / watermark
• pdf merge / split / rotate
• QR codes, hmac, bcrypt, regex extract, text diff, json/csv

setup is one line in your config:
{ "command": "npx", "args": ["-y", "toolbox-mcp"] }

works in Claude Desktop and Claude Code (also Cursor, VS Code, Antigravity). i have it connected in Claude Code right now and it just calls the tools directly.

repo: https://github.com/medoxisto/toolbox-mcp
its open source (MIT), free, would love feedback or tool ideas. what deterministic stuff do you wish Claude would stop guessing at?

Update: yo u/ClaudeOfficial heard u guys give out 6 months of free max for open source stuff. bro i basically just spent days fixing ur AIs blind spots and skill issues (mans cant read a pdf, do crypto, or process data without lying to me). does babysitting claude count? hook a brother up pls lmaoo

got tired of two things: youtube shoving ads every other video, and news sites throwing up the "please disable your ad blocker" wall. couldnt find a free one that handled both well without some pro upsell or sketchy permissions, so i built my own. its open source, GPL-3.0, code is fully public.

what it does:

• blocks ads, popups and trackers across the web
• blocks youtube ads including the mid roll ones
• gets past most of the "we detected an adblocker" walls
• no account, no telemetry, three permissions total and you can read what each does

the part people find interesting: most blockers get caught because the site checks for the side effects of blocking after the page loads. did the ad slot stay empty, did the ad script fail. mine does its work at document_start, before the detection code runs, so when the site checks "did the ad load" things look normal. thats why it slips past walls that catch the big names.

repo (read the code first): https://github.com/medoxisto/ad-blocker-chrome-extension

im not a senior dev, figured out manifest v3 as i went and it nearly killed me, so id genuinely love people who know more to tear it apart. issues and PRs welcome, a few people already sent some.

its on the chrome store too if you just want a free youtube ad blocker that actually works, but the repo is the point of this post.

Been dealing with this for a while. Forbes, Wired, a bunch of news sites and random blogs started putting up that wall where they basically refuse to show you content unless you whitelist them. I was using uBlock Origin for years and it worked great until it didn't.

The problem seems to be that sites got better at fingerprinting which extensions you have. They can scan your browser's behavior and flag you by recognizing the patterns popular adblockers leave behind.

Tried a few different things, read through some old threads here. Most suggestions were outdated or just "use a VPN" which doesn't fix the actual problem.

Then I found this extension on the Chrome Web Store: https://chromewebstore.google.com/detail/ad-blocker-%E2%80%94-block-ads-po/cfcfhjclnllekcnfeoaaiicbjlmjmojk

The name sounds generic, I almost skipped it.

The difference is how it does the blocking. It runs at the content level before those detection scripts can even check for it, so sites that normally catch you just don't trigger the wall. I tested it on about 12 sites that gave me problems before. 10 out of 12 worked completely fine. The other 2 are behind real paywalls that use adblock detection as a cover anyway.

No account needed, no email, nothing. I checked the permissions it asks for too, pretty standard stuff.

Been about 3 weeks and I haven't gone back to my old setup.

To be honest, I was getting really annoyed every time I needed to do something simple like compress an image or convert a pdf. You google it and immediately get hit with ads, or they want you to make an account just to download your file. Plus, uploading personal stuff to random servers always felt super sketchy to me.

After dealing with this for a while, I just decided to build a massive toolbox for myself. Everything runs completely locally in the browser, so no servers, no signups, and nothing gets uploaded anywhere.

So I put it all together on https://footrue.com If anything feels broken or you think of something I should add, just drop a comment here.

Happy to return the favor and check out your projects too! Thank you!

I’m currently building an app to learn Moroccan Darija. As you can see in the quick screen recording, it’s still in early development and not published anywhere yet.

Why am I doing this? Honestly, I checked out the existing apps for learning Darija on the App Store/Play Store, and they all felt super basic, outdated, and kinda boring to use. I wanted to create something gamified, interactive, and actually fun something that makes you want to keep practicing every day.

I really need your honest feedback/suggestions:

• If you’re trying to learn Darija (or know someone who is): What features do you desperately wish existed in a language app? What’s the biggest struggle you face with current resources?
• What do you think of the vibe/UI in the video? (The flashcards, pronunciation, quick quizzes, etc.) What should I change or add?

The app is still a work in progress, so feel free to roast it or drop any ideas. I just want to build something genuinely useful for the community.

Thanks a lot, bros! 🙏

Kept seeing people say "follow the whales" so I started logging the wallets making the biggest trades (10k+) and checking their actual open P&L.

Honestly surprised me. Out of the 22 biggest active wallets, only one is currently net positive on open positions. The rest are underwater some by a lot. Big size ≠ winning.

A few takeaways I've landed on:

• The biggest bettor in a market is usually NOT the smartest, just the richest/most degen
• "Smart money" only means something if you actually check if they're up
• A whale buying at a mid price (say 0.40–0.60) is a way more interesting signal than one cashing out at 0.99

Curious what the rest of you think do you actually copy whales, or just use it as one input? And how do you separate a sharp wallet from a rich-and-wrong one?
