arbor vs MCP-Nest
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.; MCP-Nest: This NestJS module simplifies exposing AI tools, resources, and prompts using the Model Context Protocol (MCP). It integrates seamlessly with NestJS's dependency injection to build complex, enterprise-ready MCP servers.
