## Description

RiMCP Hybrid is a specialized MCP server developed by Hur Lu that provides AI-powered code search and retrieval capabilities for RimWorld game modding projects. Built in C# with .NET 8.0, it combines lexical search using Lucene.Net with semantic search powered by HuggingFace transformers (e5-base-v2 embeddings), creating a hybrid RAG system that indexes both C# source code and XML definition files. The implementation features incremental indexing with file change detection, graph-based relationship tracking between code symbols, and a persistent Python embedding server for fast semantic queries, making it valuable for mod developers seeking AI assistance with understanding complex codebases and finding usage patterns across the extensive RimWorld modding ecosystem.
