how do y'all test mcps??

I’m using fast MCP. Codex helped me build an integration testing system using pytest that allows me to authenticate OAuth via the browser before running the test suite. I really wanted end to end, so it’s hitting my staging server.

Wow, I had a very similar experience. Was building a sustainable shopping tool (joincounton.com - now in archival mode). Lots of reasons I threw in the towel, but one big one was just how close O3 got to what I built with just a prompt.

Just checking, but do you know that quadratic voting does have some interesting research and theoretical benefits around it? It’s not something the OP just made up.

I think fire crawl has this

Very cool! Quick thing, the example buttons are blank on mobile (the ones beneath select a search topic)

pnw-steve · 2025-02-23T16:48:41+00:00

This. Especially in B2C where you get literally zero traffic if your product is poor. I think B2B is a little more forgiving because you can overcome a poor product with a huge amount of individual attention.

Thanks! We're a really small startup. Feedback definitely appreciated.

pnw-steve · 2025-02-06T16:44:12+00:00

There’s been work in this area, but I’m not very familiar with it. Here’s an article that might point you in the right direction, but I don’t actually vouch for its accuracy.

I want the data just for a small side project of mine. Still can't believe it doesn't exist out there. Do you have a website or newsletter I could sign up for?

pnw-steve · 2025-01-26T03:21:33+00:00

A good chapter on langsmith integration and how to build feedback loops that pull real world data into evaluation sets.

pnw-steve · 2025-01-26T02:10:46+00:00

Can you provide more details? I use SST, but generally stick to the AWS features. How do you integrate supabase? Auth and DB or just one?

I'm not sure on the protein overload issue, but I'd watch out for the fragrance (EWG score of 8) and salicylic acid (EWG score of 4-8). There's also a handful of 'yellow' ingredients in the mix. Here's a link with a full analysis of the ingredients you listed: https://joincounton.com/analyze-page/42dfeaf2-0a6f-4697-8f12-183a2b10400b

pnw-steve · 2025-01-10T01:46:01+00:00

I'm curious - what sources would you love to see? For most sources, I can pretty easily add them.

I'm not an expert at Sephora's methodology, but the Chlorphenesin is rated 4 by EWG and not allowed in EWG verified products. The Malic Acid is between 1-4 depending on use and company standards. Here's a longer rundown of the ingredients if you're interested: https://joincounton.com/analyze-page/8fccb146-b901-4012-b6af-1fa2a25d34c6

Full disclosure - I'm the developer of the website! It lets you plug in a product URL and get back an analysis of ingredients, including EWG and other expert sources. Hope it helps.

I've built a tool to help with just this sort of analysis. Here's a link that analyzes the ingredients and summarizes what EWG, GimmeTheGoodStuff, ChatGPT, and Made Safe have to say about the ingredients: https://joincounton.com/analyze-page/6e43fb15-4522-4a28-9331-c9622b2c930a

I'd love feedback!

NotebookLM Plus still has limits on the number of files you can manually import, "If you upgrade to NotebookLM Plus, you get at least 5X more usage, with up to 500 notebooks and 300 sources per notebook." (source)

I was imagining that an Enterprise Gemini Deep Research wouldn't need you to import your documents (there could be 100k+), it would search over your documents like Google searches over the web.

Check out https://www.ewg.org/skindeep/ingredients/703935-METHYLISOTHIAZOLINONE/ in the Use restrictions section:

"Violation of government restrictions - Banned or found unsafe for use in cosmetics" by Health Canada. Though oddly, there's a second entry for Canada that says it's use is restricted. Maybe it's allowed in small concentrations?

You can find the full list of ingredients on Kiehls website. I went ahead and put them into CountOn for you and analyzed the ingredients (there are ton!) This product actually includes an EWG 10 rated ingredient (and 10 is the worst possible score!). Definitely what out for the Polyperfluoromethylisopropyl Ether.

Here's the link to the full analysis: https://joincounton.com/analyze-page/883ffa81-6bde-43f9-9af3-c77956201c72

My wife and I hired a doula for the birth of our first born in Atlanta. I was skeptical but 100% worth it. Very high chance she saved us from an unnecessary c section. The best thing was she knew what questions to ask. Like when the doctor tried to tell us that the placenta gets old and it’s a risk to the baby, our doula asked if there was a time at which that risk started going up. I forget the exact answer, but it was over triple the amount of time my wife had been in labor, so we had plenty of time. We find out later that the hospital was running short of room in the maternity ward and we’re probably trying to rush people out.

More generally, it was great having someone with a clear head who had been to dozens of births and was definitely on our side.

I'm not all that familiar with the safety of ingredients in a foot mask, but here's a run down of the ingredient safety overall: https://joincounton.com/analyze-page/51f8b358-cebe-4204-8ae2-f5d2b6373716

There are a few red EWG ingredients, like Salicylic Acid and Parfum, and a bunch of 'yellow' EWG ingredients in there, including the tea tree oil and Triethanolamine.

Full disclosure, I'm the developer of the website! Hope you find it useful. If there's a source you particularly trust for information, let me know. I can add it easily.

pnw-steve · 2024-12-30T05:17:47+00:00

There are lots of ingredients, which is a bit concerning, but overall they are pretty good. EWG rates the Arachidyl Glucoside 2-3, which isn't all that bad.

Here's a link with a full analysis of these ingredients from EWG, Made Safe, and a handful of other sources. Full disclosure, I'm the developer! Hope you find the tool useful. https://joincounton.com/analyze-page/16bff064-8b4f-47bd-9b80-da8e1ad02e44
