Unreal Engine Code Analyzer MCP Server

What is Unreal Engine Code Analyzer MCP Server?

A Model Context Protocol (MCP) server that provides source code analysis for Unreal Engine codebases and custom C++ projects. It enables AI assistants like Claude and Cline to understand and analyze C++ source code including class hierarchies, references, patterns, and subsystem details.

How to use Unreal Engine Code Analyzer MCP Server?

Clone the repository, install dependencies with npm install, and build with npm run build. Add the server configuration to your Claude Desktop or Cline settings file, pointing to the built index.js. Before using any analysis tools, set either the Unreal Engine source path (set_unreal_path) or a custom codebase path (set_custom_codebase). Then issue tool commands such as analyze_class, search_code, find_class_hierarchy, or detect_patterns.

Key features of Unreal Engine Code Analyzer MCP Server

• Detailed class analysis (methods, properties, inheritance)
• Class hierarchy mapping with interface inclusion
• Context-aware code search across files
• Reference finding for classes, functions, or variables
• Subsystem analysis (e.g., Physics, Rendering)
• Pattern detection and best practices guidance
• Custom codebase support for any C++ project
• API documentation query with relevance ranking

Use cases of Unreal Engine Code Analyzer MCP Server

• Explore Unreal Engine source during game development or plugin creation
• Analyze custom game engines or graphics libraries for integration
• Understand class hierarchies and references in a C++ codebase
• Get best practices for Unreal Engine concepts like UPROPERTY or replication
• Search for specific code patterns across large projects

FAQ from Unreal Engine Code Analyzer MCP Server

What prerequisites are needed to run the server?

Node.js and npm are required. The server uses TypeScript, tree-sitter for C++ parsing, the MCP SDK, and glob for file pattern matching.

Can I analyze projects other than Unreal Engine?

Yes. Use set_custom_codebase to point to any C++ project—game engines, graphics libraries, frameworks (Qt, Boost), or any C++ application.

How do I configure the server for Claude Desktop?

Add an entry to %APPDATA%\Claude\claude_desktop_config.json with the command set to node and args pointing to the built index.js.

What tools does the server provide?

Tools include analyze_class, find_class_hierarchy, search_code, find_references, analyze_subsystem, detect_patterns, get_best_practices, and query_api.

Where does the source code data live?

Data is parsed live from the file system paths you provide—no external database is used. The server does not store or transmit your code.
