arcade-mcp vs bub

arcade-mcp: The Arcade MCP Server Framework is a Python framework for building custom Multi-modal Communication Protocol (MCP) servers. It simplifies the creation of AI-callable tools, handling aspects like secrets, authentication, and different communication transports.; bub: Bub is a small Python agent runtime built on agents.md and Agent Skills, where every stage of a turn is a pluggy hook that plugins can override. Context is rebuilt from append-only tape records, and the same pipeline serves the CLI, Telegram and custom channels.
