Summary
Pietro Zullo, co-founder of Manufact, delivers a conference talk on MCP (Model Context Protocol) apps — covering the primitives that power them, how to distribute them, and why this architecture may define how all software is consumed going forward. Manufact builds open-source SDKs under the MCPUs brand (8M+ downloads, 10K GitHub stars) and a cloud platform purpose-built for MCP server deployment and publishing.
The talk traces MCP’s evolution from its 2024 launch through the emergence of MCP UI — now formalized as MCP apps, an official protocol extension allowing servers to return interactive UI components alongside standard JSON tool outputs. Zullo walks through concrete patterns: real-time widget rendering, SVG and Remotion video generation, and a privacy-preserving dual-output model where the UI displays full data while only a sanitized summary is forwarded to the LLM provider. This last pattern addresses a known pain point for enterprise deployments where sending raw user data to model providers is prohibited.
A major focus is distribution infrastructure. MCP stores from Claude (Connectors) and Character AI have moved beyond closed design partnerships and are now accepting broader submissions, enabling one-click install experiences for end users. Manufact’s Manifold Cloud handles the full publishing pipeline — GitHub-to-server deployment, publishing validation checks, and team collaboration tooling. For developers building or iterating on MCP servers and apps, this talk covers the complete lifecycle from protocol primitives to production-ready distribution.
