Launch HN: Manufact (YC S25) – MCP Cloud
MCP just became the new API layer. Manufact is doing for Model Context Protocol what Vercel did for Next.js—and companies are already seeing 2x retention lifts.
Why it matters
MCP (Model Context Protocol) has crossed an inflection point: major AI clients (Claude, ChatGPT, Cursor) now have official app stores with dynamic discovery and one-click installation. Manufact is capturing the infrastructure layer—deployment, testing, monitoring, and analytics—for teams shipping MCPs at scale. This is the bet that if AI apps are the new browsers, MCPs are the new websites.
The key facts
6 to knowMCP is now official across major clients: ChatGPT Apps SDK (Oct 2025), store launches (late 2025), SEP-1865 standard merged (Jan 2026)
Early adoption signal: companies reporting 15%+ of usage from their MCP connectors
Retention impact: Amplitude's MCP saw 2x increase in retention after adding interactive UI
Manufact uses GitHub-to-deploy model; includes automated testing across ChatGPT and Claude clients, submission pre-flight checks, and MCP-native analytics
Founders (Pietro and Luigi) previously built mcp-use open-source SDKs; now backed by YC S25
Broader context: dynamic client discovery and UI standardization (io.modelcontextprotocol/ui) now live across platforms
