Codex CLI
codex mcp add powmcp-mobile-site-check --url https://powmcp.com/mobile-site-check/mcp

gemini mcp add --transport http powmcp-mobile-site-check https://powmcp.com/mobile-site-check/mcp

Manage, disable, or remove this connection in your agent's own MCP settings. PowMCP does not label an external connection as installed without confirmation from that client.

What it does

Renders your page in headless Chrome on four real device profiles and grades viewport scaling, sideways overflow, tap targets under 44px, and illegible text

A rendered-layout check of four measured small-screen signals, not a full mobile-friendliness or usability audit: the page loads in headless Chrome on four real device profiles (iPhone SE, iPhone 14 Pro, Galaxy S9+ and iPad Mini) and comes back graded on viewport meta scaling, sideways overflow in pixels, tap targets under the 44px platform-recommended size (WCAG 2.2's own minimum is 24px), and the share of text below the 12px legibility floor, with every finding tied to the device it appeared on.

Mobile Check

mobile_check

Renders one public URL in headless Chrome on four real device profiles (iPhone SE, iPhone 14 Pro, Galaxy S9+, iPad Mini) and grades exactly four rendered-layout signals: viewport meta scaling, sideways overflow, tap targets under 44px (the platform-recommended size: WCAG 2.2's minimum is 24px, and inline text links are exempt), and illegible text below 12px. Use only for an explicit layout or legibility symptom, or a request to rule these four causes in or out; unexplained mobile abandonment alone is outside scope. Usually done in 4-8 seconds.

Mobile Site Check questions

Scope and boundaries for Mobile Site Check.

01What can I check with Mobile Site Check?

Render https://example.com, or a public page with a reported small-screen layout problem, in the fixed iPhone SE, iPhone 14 Pro, Galaxy S9+, and iPad Mini profiles.

02How should I read the result?

Read issues from critical to warning before the score; the score deducts 30 per distinct critical issue, 20 per error, and 7 per warning after same-kind device findings are combined. Fix the viewport meta tag first, then horizontal overflow, tap targets, and legibility warnings on the named profiles. An empty issue list clears only these rendered signals, not overall mobile usability, performance, accessibility, or abandonment causes.

03What are its limits?

This measures exactly four rendered-layout signals, not overall mobile usability, performance, Core Web Vitals, accessibility conformance, or abandonment causes. The 44 px target threshold is a platform recommendation rather than WCAG 2.2's 24 px minimum, and inline text links are excluded from that target check.
