Auth Handler

Auth Handler

Ensures a valid MCP browser session exists before page exploration. Procedural checklist — not an LLM prompt.

Skip condition

If setup/auth.ts does not exist, skip this skill entirely. The explorer will proceed without auth (public routes only).

Step 1 — Check environment variables

Read credentials from .env:

• TEST_EMAIL or ADMIN_EMAIL — the admin username
• TEST_PASSWORD or ADMIN_PASS — the admin password

If both are missing → stop and report:

Auth handler: TEST_EMAIL and TEST_PASSWORD must be set in .env

Step 2 — Log in via MCP browser

The MCP browser always starts with a fresh session (no cookies). setup/auth.json is used only by Playwright test runs — it cannot be injected into the MCP browser. Always perform a fresh login here regardless of whether auth.json exists.

Execute these steps in order using Playwright MCP tools:

1. Navigate to APP_URL — wait for page to settle.
2. Click the Login button (role button, name Login).
3. Fill the Username field (role textbox, name Username) with TEST_EMAIL (or ADMIN_EMAIL).
4. Fill the Password field (role textbox, name Password) with TEST_PASSWORD (or ADMIN_PASS).
5. Click the Sign In button (role button, name Sign In).
6. Wait until the URL no longer contains /sso — use mcp__playwright__browser_wait_for with a 20-second timeout.
7. Wait for networkidle.

If still on /sso after 20 seconds → stop and report:

Auth handler: login failed — still on SSO page after Sign In. Check credentials in .env.

If login succeeds → go to Step 3.

Step 3 — Confirm to caller

Auth handler: MCP browser session authenticated. Exploration can proceed.

Note: This skill authenticates the MCP browser session only. It does NOT update setup/auth.json. Test execution uses storageState: 'setup/auth.json' (managed separately by npm run auth). MCP exploration uses this live login session.

Mid-run session expiry

If a failure shows an unexpected redirect to /login during exploration, re-invoke this skill from Step 2 to perform a fresh login.

Security note

setup/auth.json must be in .gitignore. It contains live session tokens. Never commit it. Never log its contents.
