Review frontend code and live pages against 386 quality-gated web development rules.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • review_code

    Runs a non-exhaustive static heuristic review of pasted HTML, CSS, or JavaScript against multiple frontend best practices and returns prioritized issues, fix guidance, and suggestions for manual verification. Use it when the user requests a review, audit, or debugging of source c

  • audit_url

    Fetches a public HTTPS page and performs a non-exhaustive static review of its HTML, returning prioritized issues and fix guidance. Use it when the user requests an audit of a deployed public page. Localhost, private networks, and plain HTTP URLs are refused. It does not execute

  • get_workflow

    Returns the ordered steps of a curated audit workflow, including rule slugs, priorities, and categories. Use it when the user requests a structured audit such as a pre-launch checklist. Available workflows: accessibility-essentials, comprehensive-audit, core-web-vitals, html-foun

  • get_checklist_rules

    Returns titles, priorities, verification and remediation prompts for every rule in a curated checklist. Use it when the user requests guidance for an entire checklist. includeContent optionally adds each rule’s long-form body. Available checklists: accessibility-essentials, compr

  • get_quick_reference

    Returns a compact checklist for one frontend category, filtered by priority and formatted as JSON, Markdown, or a task list. Use it when the user requests a concise checklist for a deployment, review, or team handoff.

  • get_rule

    Returns complete guidance for one known rule slug: requirements, rationale, verification and remediation prompts, code examples, sources, and related rules. Use it when the user requests detailed guidance for a specific frontend rule. Unknown slugs return similar suggestions.

  • search_rules

    Finds frontend rules by keywords, category, and priority, returning paginated slugs, titles, and short summaries. Use it when the user requests relevant practices for a technology, concern, or pattern, such as web fonts or accessible forms.

  • check_rule

    Checks a code snippet against one named frontend rule using static heuristics and returns findings and verification guidance. Without code, returns manual verification guidance. Use it when the user requests a check of a specific rule or a proposed fix. Results do not establish r

  • fix_rule

    Returns step-by-step remediation guidance and priority for one named frontend rule. Use it when the user requests implementation or fix instructions for a known issue. Optional codeSnippet provides context; the tool does not edit files or apply changes.

  • explain_rule

    Explains one frontend rule, including its background, impact on users and the business, and related categories. Use it when the user asks why a practice matters or requests educational context. It returns explanation guidance rather than applying a fix.

  • list_categories

    Lists available frontend rule categories, their descriptions, and rule counts. Use it when the user asks what the checklist covers or needs valid category names.

Common questions

Is Front-End Checklist safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed 10 days ago, and the latest version (2.0.1) reached the registry 36 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
