Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Answers "what CSS can I actually ship?" from live Baseline data and MDN browser-compat-data. Pick a tool by the question: - Which features exist for X, and are they safe yet? -> search_css_features - What became usable recently? -> whats_new - Everything about one feature -> get_feature - Which browser versions support one property/value/selector? -> check_support - Does this stylesheet work for my users? -> audit_css - How should this UI be designed, or is this page any good? -> dont_make_me_think Baseline levels: "widely" means interoperable across Chrome, Edge, Firefox and Safari (desktop and mobile) for 30+ months; "newly" means interoperable but recently so; "limited" means at least one major engine is missing it. search_css_features, whats_new and get_feature query api.webstatus.dev live. check_support and audit_css answer from bundled data (browser-compat-data 8.0.8, web-features 3.34.2) and need no network access.

search_css_features — Search CSS features
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Search CSS features on the Web Platform Dashboard (webstatus.dev) by keyword, Baseline status, and the date range in which they reached Baseline. Use this to answer questions like "which CSS features for scroll animations are Baseline yet?" or "what limited-support CSS is there for anchoring?". Returns live Baseline data. For the browser versions a specific property shipped in, use check_support instead.

whats_new — What's new in CSS
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

List CSS features that crossed a Baseline threshold within a date range, newest first. Use this to answer "what CSS can I start using now?", to write release notes, or to catch up after time away. Defaults to the last 180 days. The date is when a feature became interoperable across browsers, which is usually well after it first shipped in one.

Accepts a web-features id ("container-queries") or a display name ("Container queries"). Use search_css_features first if you do not know the id.

Advertised by the server during the last successful anonymous check.

Look up which browser versions support a CSS property, value, selector, at-rule or function, from MDN browser-compat-data bundled with this server (no network call). Give either a BCD key ("css.properties.anchor-name") or a property with an optional value ("display" + "grid"). Also reports vendor prefixes, partial implementations and the Baseline status of the feature the key belongs to.

audit_css — Audit CSS against browser targets
Advertised by the server during the last successful anonymous check.
Advertised read-only

Scan CSS source and report every feature in it that does not meet a browser support target. Targets are either a Baseline level ("baseline-widely", "baseline-newly") or an explicit browser list ("chrome 120, safari 17.4, firefox 128"). Reports the offending line, what is wrong (unsupported, too old, prefix-only, partial), and the minimum version that would work. Browserslist queries like "last 2 versions" are not supported. IMPORTANT when reading Baseline-level results: Baseline describes a whole feature, and a feature can be "Limited" because one part of it is not interoperable while the exact declaration you wrote works everywhere. "Cursor styles" is Limited, so `cursor: pointer` is reported — yet it only lacks iOS Safari, where a cursor is meaningless rather than broken. Each finding therefore also names the browsers missing that specific key, or says that the key ships everywhere and the status comes from elsewhere in the feature. Read that line before removing anything: a key that ships everywhere is still not proof the code works, since it may be inert without the parts that do not.

dont_make_me_think — Don't Make Me Think
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

UI/UX guidelines and a review of a page against them. mode="guidelines" returns the principles — Nielsen's 10 heuristics, Hick's and Fitts's laws, WCAG 2.2, neurodiversity-inclusive design, motion and microinteractions (including when Lottie or Rive are worth their bundle cost), SVG craft and animation, light-first theming, lightness and responsiveness — optionally filtered by topic. Read them BEFORE designing or building UI. mode="review" statically reviews supplied HTML and CSS, or a URL, and reports what violates which principle. The review reads source and does not render it, so it cannot measure computed contrast, real target sizes, or where focus lands — it catches what is visible in the markup, which is most of what actually goes wrong.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http css-sota-mcp https://css-sota-mcp.lusrodri.workers.dev/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add css-sota-mcp --url https://css-sota-mcp.lusrodri.workers.dev/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable css-sota-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "css-sota-mcp": {
      "url": "https://css-sota-mcp.lusrodri.workers.dev/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration

      "url": "https://css-sota-mcp.lusrodri.workers.dev/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start css-sota-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "css-sota-mcp": {
      "type": "http",
      "url": "https://css-sota-mcp.lusrodri.workers.dev/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http css-sota-mcp https://css-sota-mcp.lusrodri.workers.dev/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://css-sota-mcp.lusrodri.workers.dev/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "css-sota-mcp": {
      "serverUrl": "https://css-sota-mcp.lusrodri.workers.dev/mcp"
