arbor vs fastmcp

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.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
