Claude can now watch a web page for you, and prove what it saw

TL;DR. We shipped an MCP server for Captureze. Add it to Claude in one click, then ask Claude to screenshot any page, watch it on a schedule, tell you what changed, and issue a certificate that proves what the page said and when.

Add Captureze to Claude and sign in. Nothing to install, no key to paste.

Then ask: "Capture https://example.com and show me what it looks like."

Four things to ask on day one

"Show me what this page looks like right now." Claude takes the shot and actually looks at it. It works on sites that block bots, and you can pin the capture to a country, so "what does our checkout look like from Germany" is now an ordinary question with a picture for an answer.

"Watch our competitor's pricing page every morning at 9 and tell me when it moves." Claude sets up the schedule and then reports back with the picture and one number: how much the page changed. Not a wall of HTML for the model to guess at.

"Put this claim on the record." You get the screenshot plus a Certificate of Capture: SHA-256 of the image, UTC timestamp, where in the world it was captured from, and a public verification URL anyone can check without an account. That is the one that survives "how do we know you didn't edit it afterwards".

"Audit this site's cookie banner as seen from the EU." Claude finds the consent banner and tells you whether rejecting is as easy as accepting, with a screenshot from the right jurisdiction attached.

Why this beats handing your agent a screenshot tool

Plenty of MCP servers will take a picture of a page. They take it, hand it over, and forget it ever happened. That is genuinely fine when the question is "what does this look like".

Captureze files every capture against the page it came from, which is what makes the interesting questions answerable at all:

Ask your agent	Screenshot MCP	Captureze
What does this page look like?	yes	yes
What changed since Tuesday, and by how much?	no	yes
Has this page moved at all since you started watching?	no	yes
Check it every morning without me	no	yes
Prove the page said this, to someone who disputes it	no	yes
Is rejecting cookies as easy as accepting?	no	yes

Memory and proof. Everything else is a picture.

Install

One click, and you are done: Add Captureze to Claude, then sign in with your Captureze account.

Anything that isn't the one-click connector wants an API key. You create one in the Captureze console at Settings → API keys, copy the cap_... value it shows you once, and use it below.

Claude Code, running locally:

claude mcp add captureze --env CAPTUREZE_API_KEY=cap_xxx -- npx -y @captureze/mcp

ChatGPT, Cursor, agent frameworks, anything else that speaks MCP: point it at https://mcp.captureze.com/mcp.

The server is free and MIT, on npm as @captureze/mcp, source at github.com/Captureze/mcp. It talks to your Captureze account, so it needs a plan or the 7-day trial, which takes no card.

Every client, every option, and what happens when a capture goes wrong: the full guide.
