 Acceptance: an MCP endpoint reachable from the node without traversing the
 workstation; remote `dev-hub` registration points at it; the reverse MCP tunnel
 removed.
+
+**Progress (2026-08-24):** chart support is written and validated — a gated
+`mcp` Deployment and ClusterIP Service running the same image with
+`-m mcp_server.server`, `API_BASE` defaulted to the in-cluster API Service, and
+tcpSocket probes. `helm lint` and `helm template` are clean, and the templates
+render nothing when `mcp.enabled` is false (the default).
+
+Two things had to be fixed before the YAML would have worked:
+
+- `mcp_server/server.py` hardcoded `host="127.0.0.1"`. A Service routes to the
+  pod IP, so a loopback bind is unreachable from anywhere but the pod itself.
+  Now `MCP_HOST`, still defaulting to loopback — the MCP layer proxies an
+  unauthenticated API and must not land on every interface by accident.
+- The container command uses `-m mcp_server.server` rather than the file path,
+  so `/app` lands on `sys.path` instead of `/app/mcp_server`.
+
+Deliberately **no Ingress** for this Service, for the same reason the API's
+ingress is disabled: neither has authentication.
+
+**Blocked on a release, not on more code.** The running image is
+`main-76e6eda`, which predates the `MCP_HOST` change, so enabling `mcp` today
+would deploy a pod that binds loopback and never becomes reachable. The order
+is: merge, let CI build `main-<sha>`, then bump the tag *and* flip
+`mcp.enabled: true` in `deploy/railiance/apps/helm/state-hub-values.yaml` in one
+commit, then `helm upgrade`. The values file is deliberately left at
+`enabled: false` so an unrelated `helm upgrade` cannot ship a broken MCP.
+
+Noticed in passing, not part of this task: that values file pins
+`main-697dd49` while the cluster runs `main-76e6eda`. Declared and running
+state disagree, which deserves its own look.
