What it does

I built a lovable for MCP apps, after installing my free mcp server, you can directly generate mcp apps/tools inside your Claude, it can do all kinds of stuff! media gen/internal tools/games etc. The biggest difference this and Lovable/Replit etc. is the generated app is agent-callable, you can either use it through ui, or directly prompt inside your Claude to run it. I personally feel this makes my Claude 10x fun and productive. Instructions: https://www.constants.io/claude-tool

Describe any tool in plain English — Claude generates a real, sandboxed tool and runs it right inside the chat. One MCP install, available in every Claude conversation.

Click Add → Connect, continue with your email. Ask in a new chat to create a tool. Done — I built the tool and ran it for 6/1. $48,920 in revenue, posted to #revenue . Want me to run this automatically everyfrom constants.io

  Agent 37Mar 2026 · agent37.com · ▲401

  Hey HN, I noticed there are 1,000+ MCP skills on GitHub with zero way for creators to charge for them. So I built Agent37. Selling Claude skills today means asking customers to download your skill, set up Claude Code on their laptops, configure MCP servers, and pray it works. No trial, no updates, often you're just handing over the source. Agent37 lets creators upload a skill, share a link, and anyone can try it instantly (no Claude account needed). Built-in Stripe, creators keep 80%. Looking for feedback on the approach. Would you use something like this?

  Codemcp – Claude Code for Claude Pro subscribers – ditch API bills2025 · github.com · ▲172

  Hi all! I normally work on the PyTorch project but I've been on baby leave for the past month, so I've been playing around with AI as a user rather than a framework implementor. I really liked the agent experience with Claude Code, but I couldn't really justify spending so many dollars on API costs for random side projects. I already pay for a Claude Pro subscription though, and it turns out you can simulate many of Claude Code's features with an MCP. If you have a Pro subscription, check this out! I think it really captures the Claude Code experience quite well, without forcing you to pay…

  Claudable – OpenSource Lovable that runs locally with Claude Code2025 · github.com · ▲38

  Hey, HN! I'm Aaron. I built an open-source Lovable for Claude Code users. Platforms like Lovable, Replit Agent, and Bolt require separate API keys and $25+/month subscriptions. But if you’re already subscribed to Claude Pro or Cursor, you can use those plans directly without extra costs. Claudable runs entirely locally through Claude Code (Cursor CLI also supported) and provides: - Instant UI preview (similar to Lovable) - Web-optimized, production-ready designs - Direct Git integration - One-click Vercel deployment - Zero additional API costs It’s open source and available today. I’m…

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
