Claw Relay — OpenClaw CLI Client

If your platform supports MCP (Copilot CLI, Claude Desktop, Gemini CLI), use skills/browser/SKILL.md instead. This skill is for OpenClaw, nanobot, ZeroClaw, and other agents that call tools via exec.

⚠️ IMPORTANT: No MCP Required

Do NOT write an MCP server, bridge, or wrapper. You already have everything you need:

• The exec tool (built into OpenClaw)
• The relay-client.cjs script (in this folder)

That's it. One exec call per browser action. No MCP, no bridge, no custom server.

Setup

Set environment variables (or pass as flags):

export CLAW_RELAY_URL="wss://relay.clawrelay.dev/"
export CLAW_RELAY_TOKEN="your-token"
export CLAW_RELAY_AGENT="your-agent-id"

The client script is at skills/openclaw/relay-client.cjs in the claw-relay repo.

Usage

node relay-client.cjs [--url URL] [--token TOKEN] [--agent-id ID] ACTION [ARGS...]

Flags override env vars. Every invocation connects, authenticates, performs ONE action, prints JSON, and exits.

Actions

Workflow

navigate → snapshot → find ref → act → snapshot → verify

1. Navigate to the target URL
2. Snapshot to read the page and get element refs (e.g. e3, e7)
3. Act — click, fill, type, press using refs from the snapshot
4. Verify — snapshot again to confirm the page changed

Example: Search GitHub

# Step 1: Navigate
node relay-client.cjs navigate https://github.com

# Step 2: Snapshot to find the search input ref
node relay-client.cjs snapshot

# Step 3: Fill the search box (say ref is e3)
node relay-client.cjs fill e3 claw-relay

# Step 4: Press Enter
node relay-client.cjs press Enter

# Step 5: Snapshot to read results
node relay-client.cjs snapshot

Example: Click a Button

# Find the button
node relay-client.cjs snapshot
# Output shows button at ref e7

# Click it
node relay-client.cjs click e7

# Verify
node relay-client.cjs snapshot

Example: Take a Screenshot

node relay-client.cjs screenshot /tmp/page.png
# Output: {"ok":true,"path":"/tmp/page.png","bytes":...}

Example: Run JavaScript

node relay-client.cjs evaluate "document.title"

OpenClaw exec Integration

Use the exec tool directly. Each call connects, authenticates, performs one action, and exits:

exec: node /path/to/relay-client.cjs snapshot
exec: node /path/to/relay-client.cjs navigate https://github.com
exec: node /path/to/relay-client.cjs click e3

Set CLAW_RELAY_URL, CLAW_RELAY_TOKEN, and CLAW_RELAY_AGENT in your environment or pass them as flags each time.

Do NOT try to keep a persistent connection, start a background process, or write wrapper scripts. The CLI handles connection lifecycle automatically.

Security Constraints

• Allowlist — your agent can only access sites explicitly allowed in its config
• Blocklist — banking, email, and auth providers are always blocked regardless of allowlist
• Rate limiting — actions are rate-limited per agent
• Audit log — every action is logged with agent ID, action, target, and result

Troubleshooting

"Invalid token or agent_id"

• Agent ID is case-sensitive. Check config.yaml for exact casing (e.g., Rusty ≠ rusty)
• Make sure the token matches exactly — no extra spaces or line breaks
• The relay must be restarted after editing config.yaml

"Agent lacks scope for 'navigate'"

• Your agent's scopes in config.yaml don't include the action you're trying to use
• Common scopes: read (snapshot/screenshot), navigate, interact (click/fill/type), execute (evaluate)
• Ask the relay admin to update your scopes

Script errors

• "require is not defined" — the script must be .cjs, not .js (the repo uses ES modules)
• "Cannot find module 'ws'" — run npm install in the relay-server/ directory first

Common mistakes

• ❌ Writing an MCP server or bridge — you don't need one
• ❌ Keeping a persistent connection — each call is stateless
• ❌ Wrapping the CLI in another script — just call it directly via exec

What Makes This Different

Local browser tools require agent and browser on the same machine. Claw Relay doesn't. Your agent runs anywhere and controls the user's real browser remotely — real cookies, real sessions, real logins. No headless browser, no fake profiles.
