arbor vs claude-historian-mcp

arbor: Arbor builds a semantic dependency graph for codebases, enabling deterministic impact analysis, symbol resolution, and git-aware risk gating. It provides a CLI, GUI, and MCP integration to help developers understand and control the consequences of changes before they happen.; 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.
