There was no runnable example showing how to wire the ADK auth subsystem into an MCP toolset, or how the different built-in credential providers map onto mcptoolset.Config.Auth. examples/mcpauth is a buildable template that selects a provider via AUTH_MODE: GCP (per-user; supports interactive 3-legged consent), header API key, static bearer, 2-legged OAuth (client credentials), ADC, and service account. Comments walk through both the non-interactive path (applied transparently by the transport RoundTripper) and the interactive consent flow (adk_request_credential, resumed once the user consents). The live consent flow requires a real MCP server and GCP auth resource. Testing: go build ./..., golangci-lint run, go mod tidy -diff — all green (buildable template; no unit tests).
