lumen
Local semantic code search via MCP with Go AST parsing and offline embeddings.
What is lumen?
Lumen indexes your codebase using Go AST parsing and embeds it with Ollama or LM Studio, then exposes vector search to Claude through an MCP server. Use it for precise semantic code search without cloud dependencies.
- Index codebases with Go AST parsing for accurate code structure understanding
- Embed code locally using Ollama or LM Studio
- Perform vector-based semantic search on indexed code through MCP
- Search code without sending data to cloud services
- Integrate with Claude Code and Cursor for in-editor code search
