title: "Peekaboo bridge"
---

OpenClaw can host **PeekabooBridge** as a local, permission-aware UI automation broker (`PeekabooBridgeHostCoordinator`, backed by the `steipete/Peekaboo` Swift package). This lets the `peekaboo` CLI drive UI automation while reusing the macOS app's TCC permissions.

## What this is (and is not)

- **Host**: OpenClaw.app can act as a PeekabooBridge host.
- **Client**: the `peekaboo` CLI (there is no separate `openclaw ui ...` surface).
- **UI**: visual overlays stay in Peekaboo.app; OpenClaw is a thin broker host.

## Relationship to other desktop-control paths

OpenClaw has three desktop-control paths that intentionally stay separate:

- **PeekabooBridge host**: OpenClaw.app hosts the local PeekabooBridge socket. The `peekaboo` CLI is the client and uses OpenClaw.app's macOS permissions for screenshots, clicks, menus, dialogs, Dock actions, and window management.
- **Codex Computer Use**: the bundled `codex` plugin checks and can install Codex's `computer-use` MCP plugin (`extensions/codex/src/app-server/computer-use.ts`), then lets Codex own native desktop-control tool calls during Codex-mode turns. OpenClaw does not proxy those actions through PeekabooBridge.
- **Direct `cua-driver` MCP**: OpenClaw can register TryCua's upstream `cua-driver mcp` server as a normal MCP server, giving agents the CUA driver's own schemas and pid/window/element-index workflow without routing through the Codex marketplace or the PeekabooBridge socket.

Use Peekaboo for the broad macOS automation surface via OpenClaw.app's permission-aware bridge host. Use Codex Computer Use when a Codex-mode agent should rely on Codex's native plugin. Use direct `cua-driver mcp` to expose the CUA driver to any OpenClaw-managed runtime as a normal MCP server.

## Enable the bridge

In the macOS app: **Settings -> Enable Peekaboo Bridge**.

When enabled, OpenClaw starts a local UNIX socket server at `~/Library/Application Support/OpenClaw/<socket-name>`. If disabled, the host stops and `peekaboo` falls back to other available hosts. The coordinator also maintains legacy socket symlinks (`clawdbot`, `clawdis`, `moltbot` under Application Support) pointing at the current socket for older `peekaboo` installs.

## Client discovery order

Peekaboo clients typically try hosts in this order:

1. Peekaboo.app (full UX)
2. Claude.app (if installed)
3. OpenClaw.app (thin broker)

Use `peekaboo bridge status --verbose` to see which host is active and which socket path is in use. Override with:

```bash
export PEEKABOO_BRIDGE_SOCKET=/path/to/bridge.sock
```

## Security and permissions

- The bridge validates **caller code signatures**; an allowlist of TeamIDs is enforced (Peekaboo host TeamID plus the running app's own TeamID).
- Prefer the signed bridge/app identity over a generic `node` runtime for Accessibility. Granting Accessibility to `node` lets any package launched by that Node executable inherit GUI automation access; see [macOS permissions](/platforms/mac/permissions#accessibility-grants-for-node-and-cli-runtimes).
- Requests time out after 10 seconds (`requestTimeoutSec: 10`).
- If required permissions are missing, the bridge returns a clear error message rather than launching System Settings.

## Snapshot behavior (automation)

Snapshots are stored in memory with a 10-minute validity window and a cap of 50 snapshots (`InMemorySnapshotManager`); artifacts are not deleted on cleanup. If you need longer retention, re-capture from the client.

## Troubleshooting

- If `peekaboo` reports "bridge client is not authorized", ensure the client is properly signed or run the host with `PEEKABOO_ALLOW_UNSIGNED_SOCKET_CLIENTS=1` in **debug** mode only.
- If no hosts are found, open one of the host apps (Peekaboo.app or OpenClaw.app) and confirm permissions are granted.
