Written by the SnapRender team. SnapRender is the capture service used in this guide; the setup works on its free plan.

A lot of legal work starts with a web page. A competitor's advertising claim, a platform's terms of service on the day a client signed up, a listing that infringes a trademark, a privacy policy that changed last month. The usual routine is to open the page, take screenshots by hand, print to PDF, rename the files and attach them to the matter, then go back to Harvey to ask questions about what the page says.

Harvey can now call external tools through custom MCP connectors. If one of those tools captures web pages, Harvey can open a URL, keep the capture as a file in the conversation, and work with the page text directly. This guide sets that up and shows the prompts that make it useful.

What the connector does

With SnapRender connected, Harvey can:

  • capture any public URL as a PDF or as a PNG, JPEG or WebP image
  • capture the full page, not just the visible part, so a long terms page arrives in one file
  • capture the page as a phone sees it (iPhone, Pixel, iPad profiles), which matters when a claim or disclosure only appears on mobile
  • read the page as text, so Harvey can quote and analyze what the page says

Cookie banners are removed before the capture, so it shows the content rather than a consent dialog.

Setup: one custom connector, OAuth, nothing to install

Harvey's custom connectors talk to remote MCP servers over HTTPS with OAuth. Harvey registers itself with the server automatically, so there is no client ID or secret to copy.

  1. In Harvey, add a custom MCP connector with these settings: 
 Name: SnapRender Server URL: https://app.snap-render.com/mcp Authentication: OAuth Client ID: (leave empty) Client secret: (leave empty) Scope: (leave empty)

If you do not see the option to add custom connectors, a Harvey workspace admin needs to enable them for you.

  1. Click Connect, sign in to SnapRender and click Allow. A free account is enough to start.

  2. In Harvey Assistant, turn SnapRender on under Sources.

The one thing to remember: ask for a file

Harvey keeps files that connectors return, but it does not display inline images from tool results. If you simply ask for "a screenshot", the image is dropped and you get a description at best.

So ask for the capture as a file:

Take a full-page screenshot of https://example.com/terms as a PDF file.

SnapRender then returns the capture as an attached file, and it stays in the conversation like any document you uploaded.

Prompts that work well

Terms or policy on a given day.

Take a full-page screenshot of https://example.com/terms as a PDF file and note today's date. Then summarize the limitation of liability clause.

Advertising claims, desktop and mobile.

Capture https://example.com/product on desktop and on iPhone as files, then list every performance or pricing claim on the page and where it appears.

Reading without capturing.

Read https://example.com/privacy as text and list what it says about data retention and transfers outside the EU.

Comparing versions. Capture a page today and again next week, then ask Harvey to compare the two files. For pages you need to watch continuously, SnapRender can also capture on a schedule and alert you when a page changes, set up from its dashboard.

What it does not do

It is worth being precise about the limits, especially for evidence work.

  • Public pages only. Captures are made from SnapRender's servers, so intranet pages and pages behind a login are out of reach.
  • It is a capture tool, not a certification service. A capture records what the page showed when it was rendered. If a matter needs formal evidence with chain of custody, use the capture alongside your firm's procedures or a dedicated web evidence provider.
  • Privacy. SnapRender only receives the URLs you ask it to capture. It never sees your Harvey documents or the rest of the conversation.

Cost

The free plan includes 200 captures a month. Every screenshot or page read uses one capture, and failed captures are not counted. Paid plans start at $9 a month for higher volume.
