Visual-diff & change-detection tools that catch agentic UI drift for coding agents.
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
SNAPDIFF_API_KEY, SNAPDIFF_API_URL标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。
你需要
你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"snapdiff": {
"command": "npx",
"args": [
"-y",
"@corralimited/snapdiff-mcp"
],
"env": {
"SNAPDIFF_API_KEY": "your-value",
"SNAPDIFF_API_URL": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add snapdiff --env SNAPDIFF_API_KEY=your-value --env SNAPDIFF_API_URL=your-value -- npx -y @corralimited/snapdiff-mcp运行前请先填写空着的值。
粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

"SNAPDIFF_API_URL": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

Standalone MCP server for SnapDiff. Exposes four tools to local agents:
Hits the public SnapDiff REST API. Bring your own API key.
Get an API key at https://snapdiff.ai/dashboard, then drop the snippet for your agent below.
claude mcp add snapdiff -e SNAPDIFF_API_KEY=sk_live_... -- npx -y @corralimited/snapdiff-mcp
Or edit ~/.claude/settings.json:
{
"mcpServers": { "snapdiff": { "command": "npx", "args": ["-y", "@corralimited/snapdiff-mcp"], "env": { "SNAPDIFF_API_KEY": "sk_live_..." } } } }

| Name | Purpose |
|---|---|
snapdiff_verify_ui_change | Checks whether a visual change matches the agent's stated intent. Returns verdict (pass / expected_change_detected / unexpected_regression / no_change_detected / needs_human_review) and a next_action. Requires a project + baseline. Use this in the verification loop. |
snapdiff_compare_pages | Raw visual diff between two URLs, or a URL vs. a stored project baseline. Use for ad-hoc diffs that don't fit the verify-ui-change verdict shape. |
snapdiff_capture_screenshot | Single screenshot of a URL. |
snapdiff_html_to_image | Render HTML/CSS to an image (OG cards, social images, email headers). |
Schemas live in src/tools/ and are exported from @corralimited/snapdiff-mcp/tools. The hosted SnapDiff backend imports the same schemas so its in-process /mcp endpoint and this standalone stdio server expose an identical surface — agents see the same tool names, descriptions, and parameters whether they connect to https://api.snapdiff.ai/mcp or run this server locally.
This package speaks stdio only — your editor spawns it as a subprocess, and the Playwright-backed localhost tools run on your machine, where your dev server actually is. It does not open a port.
If you need an HTTP endpoint, use the hosted one at https://mcp.snapdiff.ai/mcp, which authenticates every request with your API key and exposes the same tool surface.
| Env var | Required | Notes |
|---|---|---|
SNAPDIFF_API_KEY | yes | Get one at https://snapdiff.ai/dashboard |
SNAPDIFF_API_URL | no | Override the API base. Defaults to https://api.snapdiff.ai/v1. |
There are no CLI flags beyond --help.
