Browser endpoints registry for mac-5 takeover and mac-7 automation

Date: 2026-03-18 Status: accepted

Purpose

Record the currently validated browser control endpoints so future automation and browser takeover tasks can reuse the right path without re-discovering ports.

mac-5 local intelligent browser takeover

Use OpenClaw local browser attach on mac-5 for takeover of the real local Chrome session.

Validated profile

OpenClaw browser profile: user
Driver/transport: existing-session via chrome-mcp

Validation result

Validated on 2026-03-18:

openclaw browser --browser-profile user status returned running: true
openclaw browser --browser-profile user tabs listed live local tabs

Operational meaning

This is the preferred path for smart takeover of the browser running on mac-5 itself.

mac-7 browser automation service

mac-7 hosts the dedicated automation Chrome instance.

Persistent local CDP service

LaunchAgent plist:
- ~/Library/LaunchAgents/com.lingyuzeng.chrome-cdp-mac7.plist
Chrome executable:
- /Applications/Google Chrome.app/Contents/MacOS/Google Chrome
Dedicated profile dir:
- ~/.openclaw/browser/mac7-automation-profile
Persistent local CDP listen address:
- 127.0.0.1:9333
Validation:
- http://127.0.0.1:9333/json/version returns standard CDP metadata and webSocketDebuggerUrl

Current tailnet-facing listener status

Observed on 2026-03-18:

Tailscale IP on mac-7: 100.64.0.23
A temporary Python TCP proxy was listening on:
- 100.64.0.23:9223
That proxy was forwarding toward a Chrome debug port for network reachability testing.

Important caveat

The 100.64.0.23:9223 listener was observed as a temporary proxy, not yet confirmed as a durable/persistent service managed by LaunchAgent or tailscale serve.

Also, tailscale serve status showed:

No serve config

So future tasks should treat the endpoints as:

stable local automation endpoint on mac-7: 127.0.0.1:9333
temporary observed tailnet endpoint on mac-7: 100.64.0.23:9223

Usage guidance

For mac-5 intelligent browser takeover: use OpenClaw local user profile.
For mac-7 automation on the same machine: use CDP on 127.0.0.1:9333.
For mac-5 controlling mac-7 across the tailnet, do not assume 100.64.0.23:9223 is durable unless a persistent proxy/serve configuration is explicitly installed later.
