Could you build this?
Partial The site and MCP server are straightforward to build, but the value lies in 600+ carefully sourced, unit-verified material property profiles, which takes domain expertise and data curation effort.
What it would actually take: The stack is a standard web app with a database, a read-only API and an MCP server wrapper. The hard part is the data: each property needs test conditions, methods and citations verified against primary sources. That requires materials science expertise and a sustained curation process.
