Playwright Network Chaos Mcp

Exposes eight Playwright network interception tools for testing how web apps handle API failures, latency, connection drops, and third-party outages. You get simulate_api_failure to force error codes, inject_latency to add delays with jitter, block_resources for analytics and CDN blocking, simulate_network_drop for mid-flight aborts, trigger_system_network_error for DNS and firewall failures, simulate_stateful_failure for retry testing, inject_response_corruption for malformed JSON, and assert_chaos_handled for pass/fail verdicts. Each tool returns structured results showing intercepted request counts, whether fallback UI appeared, console errors, and page state. Useful when you need AI agents to verify error boundaries, loading states, and resilience logic that only surfaces when networks behave badly.
