title: "Gateway-owned pairing"
---

In Gateway-owned pairing, the **Gateway** is the source of truth for which
nodes may 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, legacy 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 rotate on re-pair).
5. The node reconnects using the token and is now paired.

Pending requests expire automatically **5 minutes after the node's last
retry** — an actively reconnecting node keeps its one pending request alive
rather than generating a fresh request (and approval prompt) per attempt.

## 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, or
  expired.

Methods:

- `node.pair.request` - create or reuse a pending request.
- `node.pair.list` - list pending and paired nodes (`operator.pairing`).
- `node.pair.approve` - approve a pending request (issues a token).
- `node.pair.reject` - reject a pending request.
- `node.pair.remove` - remove a paired node. For a device-backed pairing, this
  revokes the device's `node` role: it mutates `devices/paired.json` and
  invalidates/disconnects that device's node-role sessions. A **mixed-role**
  device (for example one that also holds `operator`) keeps its row and only
  loses the `node` role; a node-only device row is deleted. It also clears any
  matching legacy gateway-owned node pairing entry. Authz: `operator.pairing`
  may remove non-operator node rows; a device-token caller revoking its
  **own** node role on a mixed-role device additionally needs
  `operator.admin`.
- `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 refresh the stored node
  metadata and the latest allowlisted declared command snapshot for operator
  visibility.
- Approval **always** generates a fresh token; `node.pair.request` never
  returns a token.
- Operator scope levels and approval-time checks are summarized in
  [Operator scopes](/gateway/operator-scopes).
- 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, filtered by
  the gateway's global node command policy (`gateway.nodes.allowCommands` and
  `denyCommands`).
- 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 that request is approved, all pending node commands from that node are
filtered and will not execute. Once pairing is approved, the node's declared
commands become available, subject to the normal command policy.

This means:

- Nodes that previously relied on device pairing alone to expose commands must
  now also 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 keeps node events from escalating 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. A self-declared `client.id` value is not enough to write
last-seen state.

## Auto-approval (macOS app)

The macOS app can 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` stays 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 a fresh `role: node` device pairing request 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 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 `Forwarded`, any `X-Forwarded-*`, or `X-Real-IP` header evidence, that
forwarded-header evidence disqualifies the loopback locality claim, and the
pairing path 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.
- In remote mode, pairing happens against the remote Gateway's store.
