dev.getsnap由 getsnap.dev 發布v1.14.5更新於 Oct 31, 2026
Screenshots, PDFs, visual diffs and accessibility audits, returned inline so a model can see them
getSnap.dev 官方 MCP 伺服器，讓助理透過託管截圖 API 對網頁截圖、產生 PDF、做像素比對與無障礙稽核。
Desktop only，透過 STDIO。 STDIO 服務會啟動本機處理程序，因此需要 SourceWeft 桌面主機。
參照 儲存庫 中的啟動說明。
Official MCP server for getSnap.dev. Gives Claude and other agents the ability to capture a web page, compare two pages and audit one for accessibility.
The capture tools return the image itself, not a link to it. A model can look at the page it just asked for, so "screenshot this and tell me what's broken" works in a single turn.
No install step. Your client runs it with npx.
Get a free API key at getsnap.dev — 100 captures a month, no card.
claude_desktop_config.json:
The same block works in any client that speaks MCP over stdio.
Cookie banners and ad overlays are removed by default on captures. Cached responses cost nothing and say so.
Large images are not inlined. Past about 1.5 MB the capture still
happened and is still on the CDN, so the tool returns the link and says
why. A full_page capture of a long page will usually hit this — pass
format: "jpeg" or full_page: false to get it inline instead.
Every capture spends a credit, so each tool description states its cost. An agent deciding whether to call something should be able to see what it will cost before it does.
compare_pages costs 2, because it launches a browser per URL.
Without a key the server exits immediately with a message explaining where to get one, rather than starting and failing on first use.
Once connected, ask your agent in plain language:
This package versions independently of the getSnap REST API and the Node and Python SDKs. It shared their number until 1.14.3, when it moved out of the API monorepo into this repository; from here it moves on its own schedule.

Capture a screenshot
Render a URL in a real browser and return the image, so you can see the page. Removes cookie banners and ad overlays by default. Costs 1 credit per call. Use full_page for the whole scrollable page, or device to emulate a phone or tablet.
url必填delaydeviceformatfull_pagereturn_imageviewport_widthviewport_heightCapture a page as PDF
Render a URL to PDF and return a link to it. Costs 1 credit per call. A PDF cannot be shown to you inline - use capture_screenshot if you need to read the page yourself.
url必填delayfull_pageCompare two pages visually
Capture two URLs and compare them pixel by pixel. Returns a similarity score and an overlay image marking what changed, which you can look at. Costs 2 credits - it launches a browser per URL. Use for staging against production, or a page before and after a change.
after_url必填full_pagethresholdbefore_url必填Audit a page for accessibility problems
Run axe-core against a URL in a real browser and return WCAG 2.0/2.1/2.2 violations by severity, with the elements responsible. Costs 1 credit per call. Returns structured findings rather than an image, so you can act on them directly.
url必填max_violationsCheck remaining credits
How many credits are used and remaining on this key this period. Free - spends no credit.
