Run real Playwright E2E tests from your AI coding agent — no Playwright knowledge required. Describe what to test in plain English, Assert writes and executes the test against your live app, and reports back step-by-step results.
Works with Claude (Desktop & Code), Cursor, Windsurf, and any MCP-compatible client.
Overview
Assert MCP connects your AI agent (Claude, Cursor, Windsurf) directly to the Assert testing platform. Generate test scenarios from plain English, run them against your live app using Playwright, and get pass/fail results with step-level details and screenshot URLs — all without writing a single line of test code.
Tools included:
- assert_list — list your saved test scenarios
- assert_generate — generate a test scenario from a description
- assert_run — execute a scenario or ad-hoc markdown test
- assert_status — poll a run for step-level results
Free tier available at https://assert.click. No Playwright knowledge required.
