4. Skip Login Forever: Playwright MCP + Claude Storage State Explained
How do you handle logins in Playwright MCP without exposing credentials? The most secure method is using Playwright’s --save-storage flag to create an auth.json file. This allows Playwright MCP to inherit an authenticated browser context, keeping your passwords safe and out of the LLM prompt.
In this JKC Tutorials guide, we bridge the gap between AI automation and security. You'll learn how to bypass the "flaky login" hurdle by injecting a pre-authenticated session directly into your MCP server.
⌨️ Quick Command Reference
To capture your session locally, use: npx playwright codegen https://www.instagram.com --save-storage=auth.json --browser=firefox
