authserver vs tsidp

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.; 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.
