Screenshots, PDFs, visual diffs and accessibility audits, returned inline so a model can see them
Official getSnap.dev MCP server that lets an assistant screenshot, PDF, visually diff and accessibility-audit web pages through a hosted capture API.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Follow the launch instructions in the repository.
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.

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.
urlrequireddelaydeviceformatfull_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.
urlrequireddelayfull_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_urlrequiredfull_pagethresholdbefore_urlrequiredAudit 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.
urlrequiredmax_violationsCheck remaining credits
How many credits are used and remaining on this key this period. Free - spends no credit.
Takes no parameters.
90% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
