它能做什么

工具名称和描述与服务器在 2026年11月7日 报告的完全一致。这些内容由作者撰写,不是我们写的;我们以纯文本形式显示。

  • search_components

    Find the Echo UI item for a job ("a settings toggle", "confirm a delete") or by name. Leads with the best fit, or says plainly that Echo has nothing for the job yet, then lists every match with its install command. The cheapest way to find out what exists, and the first call befo

  • get_component

    The full record for one component: description, install command, usage (imports + smallest working snippet), composition (part tree), examples, accessibility, motion & sound, prop table and anti-patterns. It's for before writing code that uses the component: the anti-patterns are

  • get_tokens

    The token families: Layer-3 semantic colour roles (--echo-*), sound names, motion's whole vocabulary — the motion tokens, the spring presets, the morph feels and the CSS duration and ease steps — and the shadow recipes. Any name a component's record lists under Motion is here. Ec

  • get_examples

    Just the usage examples for one component, without the rest of its record. For when the component is already chosen and only its calling convention is needed.

  • get_accessibility

    The accessibility rules a consumer of Echo can still get wrong — names on controls, form errors, announcements, focus and target size — and, with a name, what that component's accessibility was actually tested against. Echo guarantees WCAG 2.2 AA; this is the part the guarantee c

  • check_code

    Echo's check on a piece of code you've written or are about to write: colours, spacing, radii, shadows and timing off Echo's scales, raw elements where Echo has the component, props a component doesn't take, controls without a name, markup a keyboard or screen reader can't use, r

  • list_styles

    Echo's own styles, the looks Echo publishes, each with its one line and its fingerprint on the seven axes styles are placed on; or, with a name, one of them in full: its settings, rules, refusals, fonts, decisions and the slop police's word. The builder's own styles aren't here:

  • fit_styles

    Style Fit's shortlist: Echo's styles, and the builder's own passed in, measured against where a product sits on the seven axes (warmth, volume, density, formality, era, craft, ornament) and put in order: a style that misses a locked axis last, then least past tolerance first, the

  • check_style

    Whether a style.json is one Echo can apply, as `npx echo-ui-cli style check` says it: what stops it, the device it makes (light or dark), what the theme corrects for AA contrast, what the slop police stops (with the question for the builder) or the builder kept, and the decisions

  • wear_style

    What a style gives a project: a link that makes the whole Echo site wear its colours, the commands that put it in a project, and, for a project without a terminal, its theme CSS and a DESIGN.md with its rules. One of Echo's styles by name, or the builder's own style.json. A style

常见问题

Echo UI 安全吗?

它在 3 项适用的基础检查中通过了 3 项。我们没有阅读代码。在添加密钥或令牌之前,请先看看这个服务器要求哪些权限,并使用只具备所需权限的密钥。

它需要哪些密钥或代码?

注册中心没有列出必需的密钥,不过有些服务器会在首次使用时要求你登录。

它在我的电脑上运行还是在云端?

它在作者的云端运行。通过互联网连接,无需安装,但你发送的内容会经过作者的服务器。

它还在维护吗?

GitHub 仓库最后更新于–,最新版本(0.3.5)于昨天进入注册中心。

哪些应用可以使用它?

支持 MCP 的应用,例如 Claude Desktop、Claude Code、Cursor 和 VS Code。它通过 URL 连接,所以接受远程 MCP 服务器的应用也可以使用,例如开启开发者模式的 ChatGPT。

有什么可以替代它?

echo-ui-mcp

An MCP server for Echo UI. It gives a coding agent ten tools over the Echo UI registry, so the agent can look up a component's props, usage, accessibility notes and anti-patterns before it writes code with it, check what it wrote, and find and wear a style.

Install

Every client runs the same command:

{

"mcpServers": { "echo-ui": { "command": "npx", "args": ["-y", "echo-ui-mcp"] } } }

  • Claude Code: claude mcp add echo-ui -- npx -y echo-ui-mcp
  • Codex: add it to ~/.codex/config.toml as [mcp_servers.echo-ui], with command = "npx" and args = ["-y", "echo-ui-mcp"].
  • Cursor: add the block above to .cursor/mcp.json.
  • VS Code: add it to .vscode/mcp.json, under servers instead of mcpServers.
  • Other clients: any client that runs a stdio MCP server takes the same command.

Requires Node.js 20 or later.

Hosted

For tools that only connect to a server on the web (ChatGPT, claude.ai, Lovable, v0, Bolt, Claude Design), the same tools run at https://mcp.echo-ui.com/mcp: nothing to install, no account. Add it as a custom connector (a remote MCP server) with that address, or:

  • Claude Code: claude mcp add --transport http echo-ui https://mcp.echo-ui.com/mcp
  • Cursor: { "mcpServers": { "echo-ui": { "url": "https://mcp.echo-ui.com/mcp" } } }

It reads the same published documents as the package, and keeps nothing it's sent: check_code reads your code and forgets it, and its request logs hold the path, the status and the timing, never a body. Cloudflare, which hosts it, keeps those logs, with the address a request came from, for up to 7 days (privacy policy). check_code takes up to 200,000 characters, a request past what that needs is refused with 413 before it's read, and one address can send 300 requests in ten seconds and about 2 MB of large code a minute, each whole 16 KB of a request counting (429 past either, with Retry-After).

In Claude and ChatGPT, with Echo's skills

Echo's plugin carries the hosted server and Echo's three skills (Echo UI, Design Eye and Style Fit) in one install: echo-ui.com/docs/plugin. In ChatGPT it's in the plugin directory. Until Claude's directory lists it too, it installs from the docs: the Claude ZIP for claude.ai and Claude Code, and the Codex ZIP for Codex and ChatGPT desktop.

Tools

ToolTakesAnswers with
search_componentsquery?The item for a job ("a settings toggle", "confirm a delete"), or a plain "Echo has nothing for this yet", then one line per matching component with its install command. The same answer as the CLI's which. With no query, every component.
get_componentnameThe full record: description, install command, usage, composition, examples, accessibility, motion & sound, props and anti-patterns. Accepts echo-hardware-button, hardware-button or HardwareButton.
get_tokens—The colour roles (--echo-*), sound names and motion names.
get_examplesnameJust the examples for one component.
get_accessibilityname?The rules a consumer of Echo can still get wrong. With a name, that component's own record of what was tested and what is not.
check_codecode, file?Echo's check on a piece of code: the same rules as npx echo-ui-cli check, against the default theme, each finding with the Echo way to fix it. For a tool with no terminal to run the CLI in.
list_stylesname?Echo's own styles, each with its one line and fingerprint; with a name, that style in full.
fit_stylesprofile, tolerance?, yours?Echo's styles and the builder's own (by fingerprint), ranked against where the product sits on the seven axes. The same arithmetic as npx echo-ui-cli style fit.
check_stylestyleWhether a style.json is one Echo can apply, as npx echo-ui-cli style check says it.
wear_stylename or style, files?A link that makes the Echo site wear the style (one of Echo's whole, your own in its colours), the command that puts it in a project, and, for a project with no terminal, its theme CSS and DESIGN.md.

When it connects, the server also sends instructions: how to set the project up, how to wire the theme and sound, and the corrections agents most often need (Base UI's package is @base-ui/react; Echo components are installed with npx echo-ui-cli add, not npm install).

get_component returns the same text as the component's page in the Echo UI docs and its entry in llms-full.txt, plus what the component ships as: its version, the echo-ui-core range it needs, and its accessibility record. That half is read from the same registry echo-ui-cli installs from, with the same client, so the two cannot disagree.

Configuration

The server reads two published documents and re-reads them after five minutes: the catalog at https://echo-ui.com/r/catalog.json and the registry at https://echo-ui.com/e. To point it at a fork or a local build, set either:

{

"mcpServers": { "echo-ui": { "command": "npx", "args": ["-y", "echo-ui-mcp"], "env": { "ECHO_CATALOG": "/absolute/path/to/catalog.json", "ECHO_REGISTRY": "https://example.com/e" } } } }

If the registry cannot be reached the server still answers from the catalog, with the versions the catalog was built at. A copy it has already read keeps answering while its source can't be read, and is tried again every minute. If a file does not match the hash the registry published for it, the server says so rather than answering.
