description: Install or refresh Iron Proxy and its official Iron Control web console for NanoClaw. Use when selecting the Iron gateway, adding its management UI, configuring credentials and grants, or restoring the proxy, approval bridge, and agent guidance.
Add Iron Proxy gateway
Install the official iron-control console and PostgreSQL alongside one central Iron Proxy. NanoClaw core supplies the generic gateway seam and human approval flow. Read docs/gateway-seam.md before changing the integration.
Use the bundled setup scripts and the source revisions in versions.json. The console is the upstream Rails application; its UI is not generated or copied into NanoClaw. This is a local Docker installation. Reuse this copy's recorded services and keys when refreshing it.
Install the provider payload
Copy the package's provider, approval middleware, tests, and agent guidance into their normal NanoClaw paths.
The provider file makes the only product registration call. It declares idempotent sessions, typed runtime contributions, owned-resource cleanup, normalized approvals, network access, and agent guidance. NanoClaw core owns approval persistence, cards, clicks, authorization, and timeouts.
Setup pulls the pinned official Iron Control image and database image, starts them on a dedicated Docker network, creates a local operator account, and registers this copy's proxy and principal through Iron's API. It stores credentials and encryption keys in owner-only files under data/session-materials/iron-control/. The database has its own persistent volume and no published port. Neither the console credentials nor its database are mounted into agents.
The installer streams stage names and elapsed-time updates. Source downloads stop after two minutes, the image build after twenty minutes, and console startup after six minutes. It never opens a Git credential prompt. The proxy is built locally from the pinned public upstream source, so installation does not require a GitHub account or access to a private proxy image. The console and build dependencies use their pinned public images. On failure, fix the reported access or service issue and rerun setup; keep existing database volumes and encryption keys together. Raw subprocess output is not streamed because it can contain credentials.
Setup builds unmodified upstream Iron Proxy and a separate NanoClaw approval front in the same image. No Iron fork or source patch is used. The front is the only network-facing listener. It authenticates session identities, inspects each HTTP request inside HTTPS tunnels, checks the allowlist, and waits for an explicit approval before forwarding to Iron on 127.0.0.1:18080. Empty, malformed, rejected or timed-out decisions fail closed. Iron's own dial-time loopback and link-local deny rules prevent DNS aliases from reaching the internal backend. Managed control-plane updates only change Iron's credential transforms; they cannot remove the front's checks.
The front builds and runs the pinned OneCLI helper in gateway-compat/onecli-summary; do not add app-specific rules. Only method, host, path, response status, the resulting OneCLI summary and whether the request sends a body or upgrade reach the approval bridge. Raw bodies, authorization headers, query strings and Iron transform traces do not. The helper sees a bounded pre-injection body prefix; the full original stream is preserved. Read the approval-presentation contract in docs/gateway-seam.md. The build tests stock Iron, the front, and the summary helper, then records an immutable image ID and source hash.
NanoClaw's approval service uses a private Unix socket on Linux. On macOS it uses loopback with mutual TLS and a proxy-only client certificate. Credentials pass directly from Iron Control to Iron Proxy.
With NANOCLAW_GATEWAY_UNCREDENTIALED_READS=true in .env, a GET or HEAD that sends no body or upgrade skips the card when no Iron credential rule could apply to its host and method. The bridge reads the rules from the proxy's config.yaml and, when managed, from Iron Control's effective config for the principal the proxy is assigned now. It reads them fresh for each such request and keeps every card for 30 seconds after its first read, because Iron applies grant changes on its own 10-second sync. Every rule it has seen stays in scope, recorded in seen-credential-rules.json beside config.yaml, because Iron can keep applying a grant that Iron Control has dropped. Delete that file and restart the host to forget revoked grants. The card also stays when Iron Control cannot be read, when the assignment changes mid-read, when a rule has an unknown shape, when config.yaml or proxy.env is newer than the running proxy (restart it), or when proxy.env sets a custom sync interval. Two gaps remain. A grant created in the moment between that read and the forward can be used without a card. So can a grant created and revoked between two reads, if Iron synced it in between, until Iron drops it. A front built before this change never attests a payload-free request, so re-run setup to rebuild it. See docs/gateway-seam.md for the data-leak trade-off.
NANOCLAW_IRON_PROXY_PORT in .env sets the internal proxy port (default 8080). Setup uses the same value for the front listener and the agent proxy URL. This does not publish a host port. Re-run setup and restart this NanoClaw copy after changing it.
NANOCLAW_IRON_CONTROL_PORT sets the console port (default 10257). Only 127.0.0.1 is published. Set it before setup if another install uses that port; use the URL printed by setup. The official image currently targets linux/amd64; Docker on Apple Silicon runs it with emulation. On another architecture, setup checks the engine before it pulls anything and stops, printing the command that enables amd64 emulation, when the engine cannot run that image.
Source access fails: verify the pinned source is readable from this machine.
The installer uses the public source in versions.json and disables interactive
Git prompts. Check connectivity and the pinned revision, then retry.
A command times out: use the last printed stage to identify whether source
download, image build, or console startup failed. Check connectivity and Docker
health before retrying. The installer terminates the timed-out process group.
"Iron Control cannot run on this aarch64 Docker engine", or exec format error
at the Iron Control step: the pinned console image is amd64 only. Run the printed
tonistiigi/binfmt command against the Docker engine, or choose the OneCLI gateway;
then re-run setup. The registration lives in the kernel and is gone after a reboot:
re-run the command, or register it at boot (a systemd unit or your Docker host's
boot script), or Iron Control restart-loops with exec format error. Setup only checks an engine running on this machine's own kernel;
a VM or remote engine (Docker Desktop, Colima, a DOCKER_HOST elsewhere) is not
inspected and needs emulation enabled inside the engine.
The database exists but keys are missing: restore its matching control.env.
Keep the database volume and encryption keys together; do not generate replacement
keys for an existing database. nanoclaw uninstall removes both together: the
containers carry this copy's nanoclaw-install and nanoclaw-role=gateway labels
(gateway-owned: the gateway role and no session, so the update drain and residue
reaping keep them), and the uninstaller removes their Compose project's volume and
network with data/.
If the folder was deleted by hand, the error prints the docker rm -f and
docker volume rm commands that delete the old database; run them only if its
credentials can go.
The setup consumer writes NANOCLAW_GATEWAY_PROVIDER=iron-proxy only after every directive succeeds. Restart only this copy's NanoClaw service after an upgrade so its session contribution and approval bridge match the new installation. Check the proxy has synced its assigned principal before reporting the gateway ready.
The request order is front identity and allowlist → human approval → stock Iron credentials → upstream. The front also requires an explicit response decision before returning upstream data. HTTPS tunnels pin the target authority; each inner HTTP request is checked again. Streaming responses and WebSocket upgrades use this same request/response gate. Credentialed application requests use HTTPS; the approval bridge rejects plaintext HTTP destinations, except one keyless model on this machine pinned by host and port (see Serve a local model). Do not rewrite an HTTP request’s approval metadata as HTTPS to bypass that restriction. The bridge forwards every allowed HTTP request to core as a default approval request. Core uses the active agent provider’s model-domain declaration to permit model traffic without a card; other destinations retain human approval. CONNECT verifies identity; the inner HTTP request is the approval point. Existing standalone model credentials are moved into Iron Control during setup and removed from the old secret file after successful storage and grant.
Open and use the official console
Open the URL printed by setup. Give the operator the path to login.txt in the same private directory; keep passwords and API tokens out of chat and command logs. control.ts status prints only the URL and login-file location.
The pinned console provides Secrets, Credentials, OAuth Apps, and Principals. Use Secrets to create a credential, choose its source, and set its host, method, and path rules. The current console shows principals and grants but creates grants through its API. Apply a secret to this NanoClaw copy with the bundled helper:
pnpm exec tsx .claude/skills/add-iron-proxy/scripts/control.ts grant static <secret-id>
Other supported kinds are gcp, aws, oauth, postgres, and hmac. The command only grants an existing credential to this install's recorded principal. Read references/control-plane.md for the exact supported UI, source links, policy example, and verification steps.
The pinned source has no general egress Policies screen or audit search. Do not promise the screens shown in newer or hosted documentation. A grant's request rules govern credential use; the local egress allowlist remains separate.
To allow another destination explicitly, the operator runs:
For a standalone proxy without the console, omit --with-control on a fresh install. A recorded console is preserved on refresh. Both modes build the pinned public source. To reuse an independently built image, build the exact commit from versions.json
and label the image org.opencontainers.image.revision with that commit. Then run
pnpm exec tsx .claude/skills/add-iron-proxy/scripts/setup.ts --local-image <image>.
Setup checks the revision and records the immutable local image ID. All installs require the exact bundled approval-front label; a stock Iron image alone is not the full NanoClaw integration.
Codex authentication
Use the existing provider-auth entry point after /add-codex installs the
provider. Browser sign-in, device pairing, and API-key entry are the same for
all gateways; scripts/credential-store.ts supplies Iron's custody adapter.
Iron Control stores API keys and manages subscription refresh-token rotation
through its native broker. Agents receive only a synthetic auth.json file.
A subscription login uses a new, dedicated Codex session; never copy personal
Codex credentials. The setup flow and provider picker stay unchanged.
The OpenCode setup flow supports ChatGPT sign-in and API keys through Iron
Control. It installs no OneCLI service and needs no OneCLI management settings.
ChatGPT arrives as the seam's chatgpt OAuth profile: Iron creates three
records, a native broker from OpenCode's public OAuth client and refresh token,
a broker-backed bearer secret, and a separate granted secret that carries the
ChatGPT-Account-Id header; any other OAuth profile is rejected. The agent sees only placeholders. Initial sign-in and reauthentication wait for the
native broker to refresh successfully (up to two minutes) before setup continues. API keys use each backend's declared header
scheme. Setup grants the secrets to this install's principal and permits the
model hostname. Rotation and reauthentication keep IDs and grants; reauthentication
also resets a dead broker with the new refresh token. Moving a key to another
host requires confirmation and re-entering its value: Iron's update API replaces
a secret's source whenever its rules change, so a blank answer keeps a key only
on its existing host. Records use install-scoped foreign IDs, so an interrupted
save is retried on the same IDs, and missing grants are reconciled without
reading values. Before keeping or overwriting a record, setup rechecks its
ownership and rules and stops if they no longer match. Broker refresh may continue during login; a change to the broker's
client binding or the secrets' rules stops setup.
Native backends and keyless or custom HTTPS endpoints on port 443 are supported.
Setup refuses plain HTTP (except a local model, below), other ports, IP addresses
and private names such as *.home.arpa, because Iron trusts only public
certificates. Setup adds the model host to Iron's allowlist.
Follow your provider's skill to restart the host and test a real reply.
Serve a local model
A keyless model on this machine can use http://host.docker.internal:<port>/v1. Traffic still goes through Iron.
Run the server on a fixed port, bound to 127.0.0.1 (Docker Desktop) or the Docker bridge address, often 172.17.0.1 (Linux). Not 0.0.0.0: that exposes it to your network.
Enter the URL at the provider's endpoint prompt, and answer that it needs no key.
Restart the host.
Only that port and the OpenAI inference routes are reachable. Don't grant an Iron credential for host.docker.internal: Iron would send it over plain HTTP. A model that needs a key, or runs on another machine, needs https on a public DNS name.
Remove
Follow REMOVE.md. Stop only this copy's proxy and console services. Keep the database volume and encryption keys together when preserving data.
Provider credentials on shared model hosts
OpenCode and Codex use distinct non-secret markers. Iron replaces only the matching
header marker, so each runtime retains its own account on a shared HTTPS host.
Claude's managed model marker remains distinct. These replacements use
require: false: a request from another provider must pass without substitution.
The upstream API still rejects an unavailable or unmatched placeholder.
Refresh the installed provider payloads and rebuild the agent image before using
this version. Reconnect older Codex credentials to replace their host-wide injection
rules. If setup identifies a conflicting legacy or manual grant, reconnect that
provider with this version (including Claude's model credential), or remove the
conflicting grant in Iron Control. Stored secrets are write-only and are not
silently rewritten. Setup checks direct and role grants, including inactive OAuth
brokers. The installation's Iron principal remains the authorization boundary;
these markers select credentials, not permissions for separate untrusted tenants.
