codebase-memory-mcp vs lean-ctx
codebase-memory-mcp: codebase-memory-mcp is a structural analysis backend that indexes codebases into a persistent knowledge graph, drastically reducing token usage for code exploration by providing precise structural results. It integrates with AI assistants like Claude Code, offering advanced capabilities such as call graph tracing, architecture overviews, and dead code detection.; lean-ctx: lean-ctx is an open-source MCP server designed to drastically reduce LLM token costs for AI coding tools like Claude Code, Cursor, and Copilot. It achieves this by transparently compressing CLI output and file context, offering up to 99% savings and making AI coding faster, cheaper, and more effective without changing workflows.
