Interactive Feedback MCP Server: Human-in-the-Loop for AI Development

The Interactive Feedback MCP (Model Context Protocol) Server, developed by Fábio Ferreira, is a powerful tool designed to optimize AI-assisted development workflows within environments like Cursor, Cline, and Windsurf. This server facilitates a crucial human-in-the-loop approach, enabling developers to directly interact with and provide feedback to AI models during the development process. By integrating this MCP server, you can significantly enhance the efficiency, accuracy, and cost-effectiveness of your AI-driven projects.

What is MCP?

Before diving deeper, let’s clarify what an MCP server does. MCP is an open protocol that standardizes how applications provide context to Large Language Models(LLMs). Think of it as a bridge that connects AI models with the outside world, allowing them to access real-time information, leverage specialized tools, and receive direct input from users. This is crucial because LLMs, while powerful, are only as good as the data and context they receive. MCPs enable a more dynamic and interactive AI experience.

The Interactive Feedback MCP specifically addresses the challenge of ensuring that AI models remain aligned with human intent and project goals. It provides a mechanism for developers to review the AI’s output, provide corrections, and guide the AI towards the desired outcome. This iterative feedback loop is essential for refining AI models and ensuring they deliver optimal results.

Key Features and Benefits

• Human-in-the-Loop Workflow: Enables direct interaction and feedback between developers and AI models, ensuring alignment with project goals.
• Cost Reduction: Minimizes unnecessary tool calls by prompting the AI to request user feedback before completing tasks, leading to significant savings on platforms like Cursor.
• Improved Performance: Consolidates multiple tool calls into a single, feedback-aware request, optimizing AI performance and reducing latency.
• Customizable Configuration: Utilizes Qt’s QSettings for per-project configuration, allowing you to tailor the server to your specific needs.
• Seamless Integration: Designed to work seamlessly with popular AI development tools like Cursor, Cline, and Windsurf.

Use Cases

1. Code Generation and Refactoring: During code generation tasks, the Interactive Feedback MCP allows developers to review the AI’s output, identify potential errors or inefficiencies, and provide specific instructions for improvement. This ensures that the generated code meets the project’s requirements and adheres to coding best practices.
2. Documentation and Commenting: When using AI to generate documentation or add comments to code, the MCP server enables developers to verify the accuracy and clarity of the generated content. They can provide feedback on the language used, the level of detail provided, and the overall effectiveness of the documentation.
3. Testing and Debugging: The MCP server can be used to integrate AI into testing and debugging workflows. Developers can use the AI to generate test cases, analyze code for potential bugs, and provide feedback on the AI’s findings. This can significantly accelerate the testing process and improve the quality of the code.
4. Content Creation and Editing: For tasks involving content creation or editing, the Interactive Feedback MCP allows users to review the AI’s output, provide feedback on the writing style, grammar, and factual accuracy, and guide the AI towards the desired tone and message.
5. AI Agent Development: UBOS, as a full-stack AI Agent Development Platform, understands the importance of controlled and precise AI agent behavior. The Interactive Feedback MCP aligns perfectly with this philosophy, allowing developers to fine-tune agent actions and responses in real-time. This level of control is crucial for building reliable and effective AI Agents for various business applications.

Installation and Configuration

The Interactive Feedback MCP Server is designed for easy installation and configuration within your development environment. The following steps outline the installation process for Cursor:

1. Prerequisites:
   • Ensure you have Python 3.11 or newer installed.
   • Install uv, a Python package manager. Use pip install uv on Windows or curl -LsSf https://astral.sh/uv/install.sh | sh on Linux/Mac.
2. Get the Code:
   • Clone the repository: git clone https://github.com/noopstudios/interactive-feedback-mcp.git or download the source code.
3. Navigate to the Directory:
   • cd path/to/interactive-feedback-mcp
4. Install Dependencies:
   • uv sync (creates a virtual environment and installs necessary packages).
5. Run the MCP Server:
   • uv run server.py
6. Configure in Cursor:

   • Point Cursor to the running server in its settings. Refer to Cursor’s documentation for specific instructions on adding custom MCPs.

   • Manual Configuration (e.g., via mcp.json):

     { “mcpServers”: { “interactive-feedback-mcp”: { “command”: “uv”, “args”: [ “–directory”, “/Users/fabioferreira/Dev/scripts/interactive-feedback-mcp”, “run”, “server.py” ], “timeout”: 600, “autoApprove”: [ “interactive_feedback” ] } } }

     Remember to replace the /Users/fabioferreira/Dev/scripts/interactive-feedback-mcp path with the actual path to the cloned repository on your system.

Similar setup principles apply for Cline and Windsurf. Configure the server command (e.g., uv run server.py with the correct --directory argument) in the tool’s MCP settings, using interactive-feedback-mcp as the server identifier.

Development Mode

To run the server in development mode with a web interface for testing, use the following command:

sh uv run fastmcp dev server.py

This will open a web interface allowing you to interact with the MCP tools for testing purposes.

How it Works: An Example

Here’s an example of how an AI assistant would call the interactive_feedback tool:

xml <use_mcp_tool> <server_name>interactive-feedback-mcp</server_name> <tool_name>interactive_feedback</tool_name>{ “project_directory”: “/path/to/your/project”, “summary”: “I’ve implemented the changes you requested and refactored the main module.” }</use_mcp_tool>

In this example, the AI assistant is using the interactive-feedback-mcp server to call the interactive_feedback tool. The arguments section provides the necessary information for the tool to function, including the project directory and a summary of the changes made by the AI.

UBOS Integration and the Future of AI Agent Development

The Interactive Feedback MCP Server aligns seamlessly with the UBOS philosophy of empowering businesses with AI Agents. UBOS provides a comprehensive platform for orchestrating AI Agents, connecting them with enterprise data, and building custom AI Agents using your own LLM models and Multi-Agent Systems. Integrating the Interactive Feedback MCP within a UBOS-managed environment enables even finer-grained control over agent behavior and ensures that AI-driven processes are continuously aligned with business objectives.

By incorporating human feedback directly into the AI development lifecycle, you can build more robust, reliable, and effective AI solutions that drive real business value. UBOS and tools like the Interactive Feedback MCP are paving the way for a future where AI Agents are not just intelligent, but also adaptable and responsive to human guidance.

In conclusion, the Interactive Feedback MCP Server is an invaluable asset for any developer working with AI-assisted tools. Its ability to facilitate human-in-the-loop workflows, reduce costs, and improve performance makes it a must-have for modern AI development.
