Launch HN: Manufact (YC S25) – MCP Cloud
Manufact (YC S25) is a cloud platform for deploying, testing, monitoring, and publishing MCP (Model Context Protocol) apps and servers. It offers preview deployments, automated testing, analytics, and store submission checks to help development teams build and ship MCPs. The company previously built open-source MCP SDKs under the name mcp-use.
Background
- MCP (Model Context Protocol) is an open standard developed by Anthropic that lets AI assistants (like Claude, ChatGPT) securely connect to external tools, databases, and APIs. Think of it as a universal "USB-C port" for AI — instead of each AI needing custom integrations, MCP provides one standard way for AI models to interact with any service.
- This launch is for Manufact, a cloud platform (YC S25) that helps developers build, test, deploy, and monitor MCP servers and apps — roughly analogous to how Vercel helps developers deploy websites. The team previously built open-source SDKs for MCP called "mcp-use".
- The key trend: major AI clients (ChatGPT, Claude, Cursor) now support MCP and are opening app marketplaces where MCPs can be discovered and installed with one click, similar to app stores for phones. Companies like Amplitude are seeing business benefits (e.g. 2x retention improvement) from offering MCP integrations with interactive UIs.
