Can NoClick check a page's Core Web Vitals automatically?

Yes. The Pagespeed node returns Core Web Vitals for a specific URL from lab tests and Origin Core Web Vitals from real Chrome user data, along with the raw lab metrics behind them. Wire it to a schedule or a deploy trigger and a workflow can track those numbers for any page without anyone opening a browser.

Does it test mobile and desktop separately?

It does. There are separate Analyze (Mobile) and Analyze (Desktop) operations, and Run Analysis (Full) returns the complete report. One workflow can score the same URL on both form factors and compare the results side by side.

How do I connect the Pagespeed node?

The node authenticates with a Google API key for the PageSpeed Insights API, which you add once in the node's credentials. After that any workflow can call it against public URLs, so there is no per-run setup.

Can it tell me what to fix, not just the score?

Yes. Get Opportunities returns the specific improvements PageSpeed suggests for a page, and Get Audit Details gives the underlying data behind each audit. Feed those into an AI step or a ticketing node to turn a low score into an actionable list.

Can a workflow react to a failing score?

The node itself is request and response, so it does not fire on its own, but you can schedule it or trigger it from another node. Run it on a cron or after a deploy, compare the Performance or SEO score against a threshold, and branch to an alert when a page regresses.

How does Codex get access to my apps?

You connect an integration to the agent's tools handle and select which operations to expose. Codex then calls those operations as tools, authenticated with the credentials you connect in NoClick.

Is this the same Codex CLI?

Yes. NoClick runs the Codex harness for you and adds your connected apps as tools. You do not have to install or manage anything locally.

Can I trigger a Codex agent automatically?

Yes. Because it runs hosted, you can start it from a schedule, a webhook, or another app event, not just by hand.

Which apps can I connect?

Any of NoClick’s tool-provider integrations, from Slack and Linear to GitHub, Notion, Google Sheets, Postgres, and dozens more.

Codex

Connect Codex to Google PageSpeed

Give an AI agent your Pagespeed node as a tool and it can measure a page's real performance itself instead of guessing at it. It can analyze a URL on mobile or desktop, pull the Performance, SEO, Accessibility, and Best Practices scores, read Core Web Vitals and lab metrics, and list the exact opportunities to fix, calling each one as a tool while it works. Wire it into a hosted coding agent in NoClick and it can audit a page, act on what it finds, and re-check the score afterward.

What happens next

Set up in minutes

The open button drops you into a guided setup. It asks exactly this, nothing else:

Choose where it runs
On your computer through your own Codex, or hosted in the cloud. The rest of setup adapts to your choice:
Pick what it can do in Google PageSpeed
A preset of real Google PageSpeed operations. Each one becomes a tool the agent can call, and it can't touch anything outside the list.
Connect Google PageSpeed
One sign-in. The agent acts through your account, scoped to the operations you picked.
Add your personal MCP link
The last step mints a private MCP URL for this agent and walks you through exactly this, with your real link filled in. The page flips to Connected the moment your Codex first calls in.
Run this in your terminal
$codex mcp add noclick --url https://mcp.noclick.app/s/<your-link>
<your-link> is your personal server URL — setup mints it for you.

Starting points

What you can build

Every morning, run a full analysis on your homepage and post the Performance score and Core Web Vitals to Slack so regressions get caught early.

When a deploy webhook fires, analyze the key landing pages on both mobile and desktop and flag any page whose Performance score drops below your threshold.

Pull the list of opportunities for a slow page, hand them to an AI step, and open a ticket with the ranked fixes.

On a weekly schedule, collect All Category Scores for a list of URLs and append them to a Google Sheet to track SEO and Accessibility over time.

Compare lab metrics against Origin Core Web Vitals for a URL to see whether real users experience the same speed your tests report.

Capture a screenshot and the Best Practices score for each new marketing page before launch and attach both to the review.

About Codex

Codex is OpenAI's command-line coding agent. NoClick runs it as a hosted agent and lets you connect your apps to it as tools, turning it from a coding assistant into an operator that can act across your systems. Connect an integration to the agent and Codex can query, create, and update records in that app directly. You keep the Codex experience and give it real reach into the tools your team already uses.

Fast, capable code generation and editing

Good at well-scoped, concrete tasks

Strong at API and data manipulation

Familiar to teams already on OpenAI tooling

Good to know
