MCP server exposing a Node-RED instance's admin API as agent tools. Single Deployment + Service + Ingress, image tracked off the upstream releases -- the tags are v-prefixed but the ghcr image tags are not, hence the version-pattern. MCP_HTTP_TOKEN is required rather than optional: upstream's listener binds all container interfaces, so there is no loopback-trust mode. The chart therefore requires existingSecret instead of defaulting it away. readOnly defaults on, so an agent cannot deploy flows by accident.
