claude-historian-mcp vs subcog

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.; subcog: Subcog is a persistent memory system for AI coding assistants that captures decisions, learnings, and context from coding sessions. It features a single-binary distribution, three-layer storage architecture (SQLite, FTS5, usearch HNSW), MCP server integration, and Claude Code hooks. It achieves high accuracy on factual recall benchmarks.
