Two security fixes for PR #5933: 1. Add safe_mode flag to WorkflowFactory (default True) mirroring AgentFactory. Gates =Env.* exposure inside DeclarativeWorkflowState PowerFx symbols via _safe_mode_context, so workflow YAML loaded from untrusted sources no longer leaks the host's full os.environ snapshot into PowerFx evaluation. The flag is also forwarded to the internally-constructed AgentFactory so inline agent definitions follow the same policy. 2. Pin the invoke_foundry_toolbox_mcp sample's _client_provider to the resolved toolbox endpoint. The bearer-authenticated httpx client is now only returned when MCPToolInvocation.server_url matches the toolbox URL case-insensitively; any other URL gets None (the default unauthenticated path), preventing the Foundry AAD bearer token from being attached to a mis-configured or injected server URL. Mirrors the .NET sample's httpClientProvider guard. The sample is updated to opt in to safe_mode=False because its YAML intentionally uses =Env.FOUNDRY_TOOLBOX_* to keep configuration in env vars under the developer's control.
