Browserbase uses direct WebSocket connections (wss://) rather than the
standard HTTP-based /json/version CDP discovery flow used by Browserless.
This change teaches the browser tool to accept ws:// and wss:// URLs as
cdpUrl values: when a WebSocket URL is detected, OpenClaw connects
directly instead of attempting HTTP discovery.
Changes:
- config.ts: accept ws:// and wss:// in cdpUrl validation
- cdp.helpers.ts: add isWebSocketUrl() helper
- cdp.ts: skip /json/version when cdpUrl is already a WebSocket URL
- chrome.ts: probe WSS endpoints via WebSocket handshake instead of HTTP
- cdp.test.ts: add test for direct WebSocket target creation
- docs/tools/browser.md: update Browserbase section with correct URL
format and notes
