CaptureFullPage MCP

An MCP server that lets Claude capture full-page screenshots directly from Chrome.

Setup

1. Install the Chrome Extension

• Download the extension from the Chrome Web Store (or load it manually — see below)

2. Add the MCP server to Claude Code

claude mcp add capturefullpage -- npx capturefullpage-mcp

That's it. The extension auto-connects to the MCP server when Chrome is open.

What Claude can do

Tool	Description
capture_fullpage	Capture a full-page screenshot of any URL or the active tab
capture_visible	Capture just the visible viewport
capture_element	Capture a specific element by CSS selector
list_tabs	List all open browser tabs
get_tab_info	Get details about a specific tab

How it works

Claude Code  →  MCP Server (WebSocket on localhost:19876)  ←  Chrome Extension

The MCP server starts a local WebSocket server. The Chrome extension connects to it automatically. No native messaging hosts, no manual bridging — just install and go.

Loading the extension manually

If the extension isn't on the Chrome Web Store yet:

• Clone this repo and build: git clone https://github.com/HarshitSingh-PM/MCP-capturefullpage.git && cd MCP-capturefullpage && npm install && npm run build
• Open chrome://extensions in Chrome
• Enable Developer Mode
• Click Load unpacked and select the dist/extension folder
