The idea
“Launch HN: Manufact (YC S25) – MCP Cloud https://manufact.com Founder's Show HN post: Hi HN, we are Pietro and Luigi, cofounders of Manufact (https://manufact.com), a cloud for MCP apps and servers. We used to be called mcp-use, and still build open source SDKs for MCP under that name: https://github.com/mcp-use/mcp-use. We did a Show HN about that last year: https://news.ycombinator.com/item?id=44747229. Today we want to tell you about our cloud product, Manufact, which is to mcp-use as Vercel is to Next.js. Manufact is an MCP vertical cloud designed for dev teams putting MCP Apps and servers in production.You can ship, iterate on, test and monitor your MCPs, and get them ready for the store submissions. All with the best developer and agent experience in mind. Here is a demo video of the product: https://www.youtube.com/watch?v=R2rbr5OT9LI. We have been working on MCP since April 2025. Our first focus was making it easy to build agents that could use any MCP server, and a lot of people started using our SDKs. Then the harness revolution kicked off: Claude Code, Claude Cowork, ChatGPT, Codex, OpenCode started shipping agent harnesses that made most standalone agent frameworks redundant. That pushed us to the other side of the connection, the servers. If agents were going to consolidate into a few harnesses, then first-class integration with the rest of a company's systems (i.e. MCP) would become the thing that mattered, so we started building up our server SDKs. Then in succession: 1. Oct 2025. ChatGPT Apps SDK. OpenAI brings app UIs to ChatGPT, built on top of MCP and the work of mcp-ui. 2. Late 2025. The stores open. ChatGPT starts accepting app submissions, Claude grows its connector directory with selected partners. 3. Jan 2026. MCP Apps becomes official. SEP-1865 merges as the first MCP extension (io.modelcontextprotocol/ui): one UI standard any host can render. Today, all the major clients fully support MCP and are opening marketplaces of reviewed MCPs that can be one click installed. All major tech companies have an MCP server, and many Landing page content (): # Manufact — Build and deploy MCP Apps and Servers > The mcp-use SDK is the fullstack MCP framework to develop MCP Apps for ChatGPT / Claude and MCP Servers for AI Agents. Open-source. 9M+ downloads. Backed by Y Combinator. Start deploying · Browse templates · Book a call Developer resources: manufact.com/developers · developers.md · prompt.md --- ## What is Manufact? Manufact is two tightly linked things: 1. mcp-use — an open-source, fullstack SDK for building MCP Apps and MCP Servers in TypeScript and Python. 2. Manufact Cloud — a zero-config hosting platform for deploying what you built. Connect your GitHub repo once; every push auto-deploys. Together they cover the entire MCP lifecycle: scaffold → inspect → deploy → publish → monitor. --- ## Build by hand. Or with Manufact. | Without Manufact | With Manufact | | --- | --- | | Stitch together MCP server, React UI, hosting, auth, and scaling. | `npx create-mcp-use-app` scaffolds the whole stack. | | Test by connecting to a live LLM and hoping. | Visual Inspector. Sandbox testing. No LLM required. | | Manage your own deployment pipeline and branch previews. | `git push` auto-deploys via the GitHub App. | | Build for ChatGPT or Claude or Gemini — separately. | Build once. Deploy to ChatGPT, Claude, and Gemini. | --- ## Start from an SDK, a skill, or a vibe. Scaffold with the mcp-use SDK. Install a skill into your coding agent. Or describe your app and watch it scaffold. Already writing MCP servers? Drop your existing code in unchanged. - SDK — Scaffold in one command: `npx create-mcp-use-app my-app` - Skill — Install the mcp-apps-builder skill for your coding agent: `npx skills add https://github.com/mcp-use/mcp-use --skill mcp-apps-builder` - Official CLI — Install the npm CLI for scripted deploys and cloud workflows: `npm install -g @mcp-use/cli` - Vibe — Describe your MCP App and let the AI scaffold it for you. --- ## One push. Live in seconds. Connect your repo once. Every push auto-deploys to Manufact Cloud. No YAML. No Dockerfile archaeology. - GitHub App — Connect once. Every push auto-deploys. - Preview per branch — A live, unique URL for every pull request. - Custom domains — Ship your app under your own domain. SSL handled. --- ## Preview it before a user sees it. Cloud Inspector runs your MCP server against real clients. Fire tool calls, inspect JSON-RPC, swap models — no local setup. - Cloud Inspector — Debug from any browser. - Model swap — Test the same call against GPT”
