"Scratch" matching MCP servers:

An educational MCP server that wraps the Materials Project API, exposing tools to search chemical systems, get material summaries, find semiconductors by band gap, and retrieve crystal structure facts.

Enables AI agents to validate wireless communication ideas by providing standardized channel instances and physical measurements through MCP, eliminating the need to write simulations from scratch.

Enables a coding agent to search the last year of papers, repositories and packages for dated evidence that the library, format reader or model its plan assumes is unavailable already exists. This lets it reuse published work instead of rebuilding it from scratch or declaring the task impossible.
