title: "Gateway-owned pairing"
---

In Gateway-owned pairing, the **Gateway** is the source of truth for which nodes
are allowed to join. UIs (macOS app, future clients) are just frontends that
approve or reject pending requests.

**Important:** WS nodes use **device pairing** (role `node`) during `connect`.
`node.pair.*` is a separate pairing store and does **not** gate the WS handshake.
Only clients that explicitly call `node.pair.*` use this flow.

## Concepts

- **Pending request**: a node asked to join; requires approval.
- **Paired node**: approved node with an issued auth token.
- **Transport**: the Gateway WS endpoint forwards requests but does not decide
  membership. (Legacy TCP bridge support has been removed.)

## How pairing works

1. A node connects to the Gateway WS and requests pairing.
2. The Gateway stores a **pending request** and emits `node.pair.requested`.
3. You approve or reject the request (CLI or UI).
4. On approval, the Gateway issues a **new token** (tokens are rotated on re‑pair).
5. The node reconnects using the token and is now “paired”.

Pending requests expire automatically after **5 minutes**.

## CLI workflow (headless friendly)

```bash
openclaw nodes pending
openclaw nodes approve <requestId>
openclaw nodes reject <requestId>
openclaw nodes status
openclaw nodes remove --node <id|name|ip>
openclaw nodes rename --node <id|name|ip> --name "Living Room iPad"
```

`nodes status` shows paired/connected nodes and their capabilities.

## API surface (gateway protocol)

Events:

- `node.pair.requested` — emitted when a new pending request is created.
- `node.pair.resolved` — emitted when a request is approved/rejected/expired.

Methods:

- `node.pair.request` — create or reuse a pending request.
- `node.pair.list` — list pending + paired nodes (`operator.pairing`).
- `node.pair.approve` — approve a pending request (issues token).
- `node.pair.reject` — reject a pending request.
- `node.pair.remove` — remove a stale paired node entry.
- `node.pair.verify` — verify `{ nodeId, token }`.

Notes:

- `node.pair.request` is idempotent per node: repeated calls return the same
  pending request.
- Repeated requests for the same pending node also refresh the stored node
  metadata and the latest allowlisted declared command snapshot for operator visibility.
- Approval **always** generates a fresh token; no token is ever returned from
  `node.pair.request`.
- Requests may include `silent: true` as a hint for auto-approval flows.
- `node.pair.approve` uses the pending request's declared commands to enforce
  extra approval scopes:
  - commandless request: `operator.pairing`
  - non-exec command request: `operator.pairing` + `operator.write`
  - `system.run` / `system.run.prepare` / `system.which` request:
    `operator.pairing` + `operator.admin`

<Warning>
Node pairing is a trust and identity flow plus token issuance. It does **not** pin the live node command surface per node.

- Live node commands come from what the node declares on connect after the gateway's global node command policy (`gateway.nodes.allowCommands` and `denyCommands`) is applied.
- Per-node `system.run` allow and ask policy lives on the node in `exec.approvals.node.*`, not in the pairing record.

</Warning>

## Node command gating (2026.3.31+)

<Warning>
**Breaking change:** Starting with `2026.3.31`, node commands are disabled until node pairing is approved. Device pairing alone is no longer enough to expose declared node commands.
</Warning>

When a node connects for the first time, pairing is requested automatically. Until the pairing request is approved, all pending node commands from that node are filtered and will not execute. Once trust is established through pairing approval, the node's declared commands become available subject to the normal command policy.

This means:

- Nodes that were previously relying on device pairing alone to expose commands must now complete node pairing.
- Commands queued before pairing approval are dropped, not deferred.

## Node event trust boundaries (2026.3.31+)

<Warning>
**Breaking change:** Node-originated runs now stay on a reduced trusted surface.
</Warning>

Node-originated summaries and related session events are restricted to the intended trusted surface. Notification-driven or node-triggered flows that previously relied on broader host or session tool access may need adjustment. This hardening ensures that node events cannot escalate into host-level tool access beyond what the node's trust boundary permits.

Durable node presence updates follow the same identity boundary. The `node.presence.alive` event is
accepted only from authenticated node device sessions and updates pairing metadata only when the
device/node identity is already paired. Self-declared `client.id` values are not enough to write
last-seen state.

## Auto-approval (macOS app)

The macOS app can optionally attempt a **silent approval** when:

- the request is marked `silent`, and
- the app can verify an SSH connection to the gateway host using the same user.

If silent approval fails, it falls back to the normal “Approve/Reject” prompt.

## Trusted-CIDR device auto-approval

WS device pairing for `role: node` remains manual by default. For private
node networks where the Gateway already trusts the network path, operators can
opt in with explicit CIDRs or exact IPs:

```json5
{
  gateway: {
    nodes: {
      pairing: {
        autoApproveCidrs: ["192.168.1.0/24"],
      },
    },
  },
}
```

Security boundary:

- Disabled when `gateway.nodes.pairing.autoApproveCidrs` is unset.
- No blanket LAN or private-network auto-approve mode exists.
- Only fresh `role: node` device pairing with no requested scopes is eligible.
- Operator, browser, Control UI, and WebChat clients stay manual.
- Role, scope, metadata, and public-key upgrades stay manual.
- Same-host loopback trusted-proxy header paths are not eligible because that
  path can be spoofed by local callers.

## Metadata-upgrade auto-approval

When an already paired device reconnects with only non-sensitive metadata
changes (for example, display name or client platform hints), OpenClaw treats
that as a `metadata-upgrade`. Silent auto-approval is narrow: it applies only
to trusted non-browser local reconnects that already proved possession of local
or shared credentials, including same-host native app reconnects after OS
version metadata changes. Browser/Control UI clients and remote clients still
use the explicit re-approval flow. Scope upgrades (read to write/admin) and
public key changes are **not** eligible for metadata-upgrade auto-approval —
they stay as explicit re-approval requests.

## QR pairing helpers

`/pair qr` renders the pairing payload as structured media so mobile and
browser clients can scan it directly.

Deleting a device also sweeps any stale pending pairing requests for that
device id, so `nodes pending` does not show orphaned rows after a revoke.

## Locality and forwarded headers

Gateway pairing treats a connection as loopback only when both the raw socket
and any upstream proxy evidence agree. If a request arrives on loopback but
carries `X-Forwarded-For` / `X-Forwarded-Host` / `X-Forwarded-Proto` headers
that point at a non-local origin, that forwarded-header evidence disqualifies
the loopback locality claim. The pairing path then requires explicit approval
instead of silently treating the request as a same-host connect. See
[Trusted Proxy Auth](/gateway/trusted-proxy-auth) for the equivalent rule on
operator auth.

## Storage (local, private)

Pairing state is stored under the Gateway state directory (default `~/.openclaw`):

- `~/.openclaw/nodes/paired.json`
- `~/.openclaw/nodes/pending.json`

If you override `OPENCLAW_STATE_DIR`, the `nodes/` folder moves with it.

Security notes:

- Tokens are secrets; treat `paired.json` as sensitive.
- Rotating a token requires re-approval (or deleting the node entry).

## Transport behavior

- The transport is **stateless**; it does not store membership.
- If the Gateway is offline or pairing is disabled, nodes cannot pair.
- If the Gateway is in remote mode, pairing still happens against the remote Gateway’s store.
