# Pair a phone with Build Remote Agent

Wave can use **Build Remote Agent** as a pairing device: the paid iOS/Android app spectates (and can inject into) this desktop Wave session through the free MIT [`gbr-agent`](https://github.com/LinespottingOrg/GrokBuildRemote-Agents). Phone and PC never open ports to each other.

Website: [grokbuildremote.com](https://grokbuildremote.com/)
Protocol: `gbr/1` · need agent **v0.6.0+**

Independent product by Linespotting AB. Not affiliated with xAI or SpaceX.

This does **not** replace Wave AI, durable SSH, or [Claude Code tab badges](./claude-code). The phone is spectator + veto. Orchestration stays in Wave.

## Install + pair

```bash
# macOS / Linux
curl -fsSL https://grokbuildremote.com/install.sh | bash
gbr-agent version # must print v0.6.0 or newer
gbr-agent pair # QR in browser + printed 8-char code
gbr-agent run # leave running

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Handle the macOS/Linux PATH after installation.

When ~/.local/bin is not already in the current shell's PATH, the installer cannot update that shell. The documented gbr-agent version command at Line 23 then fails with command not found. Add the export or instruct the user to open a new terminal before running the version check. (grokbuildremote.com)

Proposed documentation fix 
 # macOS / Linux
 curl -fsSL https://grokbuildremote.com/install.sh | bash
+export PATH="$HOME/.local/bin:$PATH"  # or open a new terminal
 gbr-agent version

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@docs/docs/gbr.mdx` around lines 20 - 25, Update the macOS/Linux installation
instructions before the gbr-agent version check to account for ~/.local/bin not
being present in the current shell PATH: add the required PATH export or
explicitly instruct users to open a new terminal, then preserve the existing
version, pair, and run commands.

```

```powershell
# Windows
irm https://grokbuildremote.com/install.ps1 | iex
gbr-agent version
gbr-agent pair
gbr-agent run
```

Phone: open Build Remote Agent → **Scan QR from computer** (or type the 8-char code). **Unpair** in Settings before changing PCs. Force-close is not enough.

## Attach

After `gbr-agent run`:

Document the separate gbr-mcp installation and MCP client configuration.

The agent installer does not install a standalone gbr-mcp command. Document the Node.js 20+ prerequisite, repository clone, npm install, diagnostic command, and the MCP configuration with "command": "node" and an absolute bin/gbr-mcp.js path under mcpServers.

Optional: `wsh` stays Wave's workspace CLI. GBR attach is only `:8788` / `gbr-mcp`.
