User Feedback MCP is a lightweight MCP server designed to enable human-in-the-loop workflows within MCP-enabled tools such as Cline and Cursor. It provides a user interface to collect user feedback during interactive tasks and supports testing of desktop applications that require complex user interactions. The README outlines installation with uv, registering the server in Cline's MCP Servers configuration, and a sample .user-feedback.json that controls how commands are run and whether they execute automatically on startup. A recommended prompt snippet guides LLM prompts to invoke the user_feedback MCP tool before task completion, ensuring feedback is gathered before marking work as complete. The project exposes a web interface at http://localhost:5173 for testing MCP tools and demonstrates an Available tools block that shows how to call the user_feedback tool with a JSON argument object. This setup emphasizes testability and repeatable steps for integrating user feedback into AI-assisted workflows.
