authserver vs loomcycle

authserver: Authplane is a self-hosted authorization server designed for the Model Context Protocol (MCP), simplifying secure authentication and authorization for AI agents and services. It handles token issuance, validation, IdP federation, and agent-to-agent delegation, offering a complete solution for securing MCP servers.; loomcycle: loomcycle is a lightweight, self-hostable agentic runtime implemented as a single Go binary, designed to run alongside your application. It provides a hardened agent loop, multi-provider routing, memory, and channel primitives for building robust AI agent systems, offering a unique sidecar approach instead of embedded libraries or managed cloud services.
