GUI-MCP

Overview

GUI-MCP is a visual development tool that allows users to create FastMCP servers through a node-based interface similar to Unreal Engine's Blueprints. It provides a Turing-complete visual programming environment with support for creating tools, resources, and prompts through connecting nodes without writing code. The tool features live code preview, simulation of tool calls, and the ability to export generated Python code for running MCP servers.
