}Attempted to read tenant/app context for app_code `merino` via the tenant_context_read tool, but the call failed because the required backend transport/endpoint is not bound in this environment. No tenant data (namespaces, workloads, owners, or action envelope) could be retrieved. No write actions were performed.
Re-run the request binding transport 'stub' (i.e. {"tenant.context.read": {"transport": "stub"}}) to retrieve sample data in this test deployment, since no live Backstage endpoint is available.
Alternatively, set the MCP_BACKSTAGE_ENDPOINT environment variable to a valid Backstage URL so tenant_context_read can query live data for app_code 'merino', then re-run the read.
