I'm 13, and I built an open-source MCP that gets AI coding agents to actually talk to each other

Claude Code, Antigravity, and OpenCode, three different companies, same repo, same time. They discussed. Nothing broke. All free, all running locally on my machine.

We got accepted into Google Cloud for Startups — here’s why that matters for us

Hey PH community

We re currently building MasterPlan, a SaaS platform for paid media professionals, and we re still in waitlist mode.

Recently, we were accepted into the Google Cloud for Startups program and I wanted to share why this milestone actually matters at this stage.

For early-stage SaaS products, infrastructure is a strategic decision, not just a technical one.

DMT

Hi everyone
I m the founder and developer of DMT.

This project was built around one simple idea: people should decide who can contact them before communication begins.

DMT is currently in early Android testing, so I m especially interested in honest feedback about onboarding, invitations, trusted contacts and everyday usability.

If you test it, please tell me what feels clear, confusing or unnecessary. Every real-world observation helps.

I applied financial market-making logic (IBKR TWS) to eBay tech deals. Here is my free extension.

Hey everyone,

As a developer and hardware enthusiast, I got tired of doing manual price research and calculation every time I wanted to buy or flip used IT gear.

So I built a free browser extension that treats the used electronics market like a financial asset class. It acts like a mini Trading Workstation (TWS) directly overlaid on eBay:

  • Real-time Valuation: Instantly calculates the weighted market median price using API data.

  • Smart Risk/Condition Assessment: Runs background logic and OCR image checks (detecting everything from pristine chassis to minor wear like a slightly scratched asset tag).

  • Instant Margins: Shows you the exact spread, target margin, and whether a deal is a "Green Signal" buy or not.

What feature would make VocalAI a no-brainer for you?

We've been live for 10 days now. We have voice cloning, 200+ voices, multi-voice scripts, auto-split for long content all for a one-time payment.

But I want to hear from you directly.

What's the one thing missing that would make this an instant buy for your workflow? Brutally honest feedback welcome I'm reading every reply.
