[Bug] macOS: Browser connection fails with "Cannot read properties of undefined (reading 'url')" despite doctor showing success

[cuishiqing]

Environment

• OS: macOS (Darwin 25.3.0)
• opencli version: v0.9.5
• @playwright/mcp: [运行 npm list -g @playwright/mcp 查看]
• Node.js: [运行 node -v 查看]
• Chrome: 已安装并运行
• Playwright MCP Bridge: 已安装

Bug Description

opencli doctor --live 显示所有检查通过，但实际运行命令时报错连接浏览器。

Steps to Reproduce

1. Install: sudo npm install -g @jackwener/opencli@0.9.5
2. Setup: opencli setup (token detected successfully)
3. Verify: opencli doctor --live → All checks passed
4. Run: opencli bilibili hot --limit 10 -f json

Expected Behavior

Return Bilibili hot videos in JSON format

Actual Behavior

Error [BROWSER_CONNECT]: ### Error
TypeError: Cannot read properties of undefined (reading 'url')
Hint: Please check if the browser is running or if the Playwright MCP / CDP connection is configured correctly.

这里浏览器是开的debug port模式还是什么？

Additional reproduction info

Environment:

• macOS Darwin 24.6.0 (Apple Silicon)
• opencli v0.9.8
• @playwright/mcp v0.0.68
• Chrome 146.0.7680.80
• Node.js 22+
• Playwright MCP Bridge extension installed

Confirmed behavior:

• opencli doctor --live → ✅ all checks pass, browser connected in 5.2s
• opencli hackernews top → ✅ works (public API, no browser)
• opencli bilibili hot -v → ❌ fails at [1/4] navigate → https://www.bilibili.com

Root cause analysis:

The TypeError: Cannot read properties of undefined (reading 'url') is not thrown by opencli code — it originates from @playwright/mcp v0.0.68 server-side during the browser_navigate tool call. opencli's Page.call() method in src/browser/page.ts correctly detects the ### Error prefix in the MCP response text and wraps it in a BrowserConnectError.

This suggests a compatibility issue between @playwright/mcp v0.0.68's browser_navigate implementation and the Chrome extension bridge. The MCP server appears to receive an undefined page/response object when navigating via the extension relay.

What I tried (all failed):

1. Extension mode with token ✅ configured → same error
2. CDP mode (--remote-debugging-port=9222) → opencli still routes through extension mode
3. OPENCLI_CDP_ONLY=true + PLAYWRIGHT_CDP_ENDPOINT → timeout connecting to extension WebSocket
4. Downgrading to @playwright/mcp@0.0.60 → extension connection timeout (version mismatch)

Suggestion: The issue might be fixed by pinning a compatible @playwright/mcp version in opencli's dependencies, or by adding a fallback in the navigate step when the MCP response is undefined.
