Rapidly MCP Server

Rapidly works inside your AI agent. Bring an idea you already have, or ask it to generate one from a company website. In about five minutes, you get a build prompt for the smallest Pretotyping experiment worth running. It is available as a remote MCP endpoint.

Teams that work with idea validation, pretotyping and rapidly and want a hosted endpoint instead of running a local process.
