emilia-protocol vs tsidp

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.; tsidp: `tsidp` is an experimental OpenID Connect (OIDC) and OAuth Identity Provider that integrates with your Tailscale network, enabling applications to authenticate users using their Tailscale identities. It supports both OIDC-compatible applications and authenticated MCP client/server connections, offering flexible deployment options via Docker or direct Go execution.
