We built an MCP Test Kitchen aka "WTF Simulator" so you don't have to
TL;DR: we built a configurable test environment for exercising happy and not-happy scenarios using an MCP Test Kitchen, and we made it public to everyone.

MCP Test Kitchen was built by the engineers at Cakewalk, where we work on agent access and permissions. We ship an MCP client of our own, and a client that mishandles what a server sends it is not only a bug: it is a guardrail that did not hold. We needed a server that gets it wrong on demand, so we built one. Learn about Cakewalk.
