A simple server to support mocking responses from any server / service that uses HTTP. The expectations that configure how the MockServer will respond to incoming requests can be setup using any language that can create JSON. A simple client is provided to make this easy in Java. MockServer includes a built-in MCP (Model Context Protocol) server for AI coding assistant integration.
