If you've used Cypress Cloud MCP, you know what it looks like when your agent triages a CI failure on its own: no copy-pasting, no context switching.

But what about when you're developing locally? When a test fails in cypress open, your agent is still on the outside. It can't see the runner, the DOM, or what the app looked like when it broke. You're still the one relaying that information.

Connecting the Chrome DevTools MCP to your Cypress session changes that. Your agent gets direct access to

Cypress's platform is a resource for developers and QA engineers, offering insights into end-to-end testing, test automation frameworks, and modern web application testing. Through articles, tutorials, and documentation, Cypress offers insights into writing and running automated tests for web applications. Developers can learn about Cypress's testing features, including real-time feedback, browser snapshots, and debugging tools, to ensure the quality and reliability of their web applications.

Connecting the Chrome DevTools MCP to a local Cypress session lets an AI agent directly access the live browser state during test failures — including DOM state, console logs, network requests, and Cypress command logs. Setup requires just two steps: setting a Chrome remote debugging port in the MCP config and passing the same port via CYPRESS_REMOTE_DEBUGGING_PORT when launching cypress open. This complements Cypress Cloud MCP (for CI triage) by covering the local development loop, enabling agents to autonomously diagnose and fix failing tests without manual context-relaying.
