MCP Nest can now handle multiple separate config deployments. So you can have one config for daily life in Claude, and one with dev tools in Cursor or VSCode 💁‍♀️

Small morning hacked-together project: esim.d.pn

eg) esim.d.pn/country/viet...

Tiny site to compare Airalo and Nomad eSIMs. May add others at some point but I wanted to focus on the providers that I actually use and trust

Using Crush + Claude as my travel @TripIt secretary to handle my flights, accommodation, etc
All hooked up through @microfnhq functions
Works really well! 🙂

This is the first time I'm seeing Claude use "Holy shit" 😂

Crush + @microfnhq is a lovely combination
Gave it a task to debug some stuff and it proactively creates new functions on mfn, executes them, checks status and iterates

All through the microfn MCP server, it's like giving AI a sandboxed js environment

Okay, mcpnest.dev is now fully OAuth Remote MCP compatible. Ready to be plugged into Claude or ChatGPT ✨

Quick new addition to mcpnest.dev:

You can now toggle individual tools to include/exclude them from the aggregated MCP server

To save tokens, reduce context pollution or exclude stuff you just never need anyway

Tried using Jules again to see if it got any better, but the GitHub trigger STILL causes it to implement any change on top a super outdated HEAD lol
This only happens when you trigger it through GitHub

Reported this a dozen times but I guess I'm the only one using this feature

For example, you can use the `ask-perplexity` MCP (local only) in Claude through remote connectors, including on mobile

Made a thing - mcpnest.dev
Little service to move locally hosted MCP servers into the cloud, to use with remote MCP clients

Super experimental but works quite nicely so far! Need a few testers 👀

Dang, gpt-oss-20gb is very snappy on my "old" M1 Max

Asked Gemini to write a commit message for me, and it automatically renamed me to "David Herman"

Gemini can be the most powerful, but also the most derpy model...

First time seeing Claude Code fully overloaded. Never had this message before
July 15, 2025 at 10:30 AM
These Gemini code review comments aren't getting better are they 😂

fixmyjapanese.com organically reaching 600 clicks last month 🎉

Glad to see some people find it valuable enough to come back!

(Especially after the kind folks on reddit really hated on it)

Super happy to soft-launch microfn.dev, a cloud runner for tiny composable functions

Write a function, hit save, and it’s live 🙌
URL, webhook, cron, or MCP tool

Built-in AI function generator + community templates you can remix. In alpha so feedback is welcome!

It's like having one of these super senior know-all engineers in your team, that just HAS to find at least something to point out
June 26, 2025 at 7:38 AM
Wow, thanks Gemini Code Assist. I'm glad this Medium Priority issue got caught in code review, almost shipped this to production 😨

Google search console is telling me that some people are googling my full name to find my david.coffee page 😳

Who's googling me and why
