lumen vs claude-historian-mcp

lumen: Lumen is a 100% local semantic code search engine for AI coding agents. It uses open-source embedding models, SQLite, and your CPU to provide fast and cost-effective code understanding. No API keys or cloud required.; claude-historian-mcp: claude-historian-mcp is an MCP server that gives Claude access to your conversation history locally. It provides two tools (search and inspect) with 11 scopes, zero dependencies, and runs completely offline. It helps find past solutions, track file changes, and learn from previous work without burning tokens on idle.
