Fathom

关于

Fathom is a free, open-source Rider plugin designed to bridge the knowledge gap for AI coding assistants working with Unreal Engine 5 C++ projects. Traditional LLMs often struggle with UE5 projects due to their reliance on binary assets linked to C++ code, leading to hallucinations and inaccurate code generation. Fathom solves this by exposing the project's full context, including C++ code, Blueprints, and asset relationships, through Model Context Protocol (MCP) tools. This allows your LLM agent of choice to query pertinent UE5 data on demand, ensuring it works with an accurate, up-to-date understanding of your project.

主要功能

• Solution-Wide Code Analysis for LLMs
• Integration with various LLM agents (e.g., Claude, Gemini, Cursor)
• 4 GitHub stars
• Blueprint and Asset Discovery for AI Assistants
• Over 15 MCP Tools to inspect UE5 project aspects
• Automatic Data Freshness for Project Context

使用案例

• Improving LLM accuracy for C++ development in Unreal Engine 5 projects
• Allowing AI assistants to understand Blueprint relationships and asset dependencies
• Providing LLMs with real-time, solution-wide code diagnostics and inspections
