Unreal Engine Code Analyzer

Read an Unreal Engine codebase the way a senior engineer does — class internals, inheritance chains, every reference to a symbol, and the UPROPERTY patterns you should be following.

LABSCO SUMMARY

It answers Unreal questions with Unreal's own conventions attached.

The structural tools — class analysis, hierarchies, references — are what you would expect. The pattern detection is the part worth having: it finds a UPROPERTY, tells you a Category specifier would help, and links to Epic's specifier reference, which turns an analysis session into a review. And because the parser is generic C++, the same tools work on a Qt app or a custom engine once you set the codebase path.

What it is

An MCP server that parses C++ with tree-sitter and answers structural questions about it. It ships with Unreal Engine knowledge — subsystem overviews, pattern detection, best-practice guidance — but it will point at any C++ codebase, not only Unreal's.

What you get

  • Class internals: properties with types and access levels, methods with return types and virtual flags — analyze_class
  • Inheritance chains resolved all the way up, optionally including implemented interfaces — find_class_hierarchy
  • Every reference to a class, function or variable, with the file, line and surrounding context — find_references
  • Regex-capable code search scoped by file pattern, with comment inclusion optional — search_code
  • Pattern detection over a file that names the Unreal pattern, points at the line, and suggests improvements with documentation links — detect_patterns
  • Best-practice guidance for UPROPERTY, UFUNCTION, Components, Events, Replication and Blueprints, each with concrete examples — get_best_practices
  • API documentation search extracted from source comments, filterable by category and module, with relevance-ranked results — query_api
  • Subsystem overviews naming the core classes, key features and common use cases for areas such as Physics — analyze_subsystem
  • The same analysis pointed at any C++ project — a custom engine, a graphics library, a Qt application — set_custom_codebase, set_unreal_path

Requirements

Node, and a build from source: clone, npm install, npm run build, then register the built build/index.js in your Claude Desktop or Cline config. Before any analysis tool works you must set a path — either the Unreal Engine source directory or a custom codebase root — and the server errors clearly if you have not. Built on TypeScript with tree-sitter and tree-sitter-cpp for parsing. The subsystem analysis tool is the one part that is Unreal-only.

Setup effort

Build from source — git clone https://github.com/ayeletstudioindia/unreal-analyzer-mcp
