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.

get_quick_referenceReturns 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_ruleReturns 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_rulesFinds 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_ruleChecks 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_ruleReturns 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_ruleExplains 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_categoriesLists available frontend rule categories, their descriptions, and rule counts. Use it when the user asks what the checklist covers or needs valid category names.
We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 10, 2026

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed 10 days ago, and the latest version (2.0.1) reached the registry 36 days ago.
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.
