Arbor

Arbor is an open-source, graph-native MCP server providing deep, explainable code analysis for AI assistants such as Claude, Cursor, and other MCP-compatible clients. It replaces embedding-based retrieval with semantic dependency graphs, enabling deterministic answers to code-related questions such as impact analysis, call hierarchies, and architectural pathfinding. Arbor integrates with major development languages and version control systems (like Git), supporting use cases in code review, developer productivity, CI pipelines, and refactoring risk analysis. It serves developers, code assistants, and teams seeking smarter, context-aware code intelligence natively accessible via MCP.
