authserver vs emilia-protocol

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.; emilia-protocol: EMILIA Protocol is an open-source framework designed to provide action-level authorization and verifiable evidence for autonomous AI agents, ensuring that machine actions are explicitly approved by a human or institution. It acts as a consequence firewall, preventing unauthorized or unverified consequential actions by agents and enabling audit-ready compliance for AI deployments.
