Refine auth server integration design - Move embedded auth server wrapper to pkg/authserver/runner/ for better dependency ordering (proxy runner consumes authserver APIs) - Replace auth-server-specific transport changes with generic PrefixHandlers mechanism (map[string]http.Handler) to keep transport package agnostic - Add Alternative 3: Auth Server Sidecar Container to alternatives considered, noting tradeoffs vs embedded approach (secret/process isolation vs implementation complexity and operational overhead)

Summary
This RFC proposes integrating ToolHive's authorization server (
pkg/authserver/) directly into the proxy runner process for Kubernetes deployments. This enables MCP servers to authenticate users via upstream identity providers (Okta, Azure AD, etc.) and issue tokens for MCP access.Key Changes
