Empower Claude Code to run automated Playwright tests, fetch its own SMS verification codes via MCP, and complete full end-to-end user journeys.
Autonomous coding agents like Claude Code can author test code, launch headless browsers, and inspect application output. However, user authentication forms with SMS 2FA historically blocked autonomous execution. By connecting Claude Code to SMSRiver's MCP server, agents can test complete authentication lifecycles end-to-end.
1 The Autonomous Verification Workflow
1. Claude Code generates test script and launches Playwright.
2. When the phone prompt appears, Claude Code calls mcp__smsriver__get_active_numbers(country='US').
3. Enters the phone number into the form.
4. Calls mcp__smsriver__extract_otp(phone_number='+12025550199').
5. Receives the 6-digit code in its reasoning context and enters it to complete verification.

No. The MCP tool returns the parsed OTP directly into the model's tool-call response, allowing 100% autonomous execution in CI environments.
