Screenshot MCP Server: Enhancing AI Application Integration with Model Context Protocol

Overview: What is Screenshot MCP Server?

The Screenshot MCP Server is an implementation that leverages Puppeteer to capture screenshots of any web page or local HTML file. This server aligns with the broader Model Context Protocol (MCP) ecosystem, enabling seamless and standardized integration for AI applications like Claude Desktop, Continue, Cursor, among others. By providing a robust toolset for capturing visual data, this MCP server enhances the capabilities of these applications in various use cases.

🔧 Core Features & MCP Capabilities

1. Capture Screenshots

One of the primary features of the Screenshot MCP Server is its ability to capture both web and local HTML files as screenshots. This capability supports a wide range of AI workflows where visual data is crucial. With configurable viewport dimensions, full page screenshot support, and customizable output paths, this server caters to diverse use cases.

2. Viewport Customization

The server allows setting the viewport width and height in pixels, ranging from 1-3840 for width and 1-2160 for height. This customization ensures that screenshots are taken at optimal resolutions suitable for various AI applications.

3. Full Page Screenshot Support

By enabling full page screenshot support, this server can capture scrolling pages that extend beyond the initial viewport. This feature is particularly useful for complex web applications and documents where content may be spread across multiple screens.

4. Custom Output Path Management

Users have the flexibility to specify custom output paths for saved screenshots. This functionality ensures that captured images are stored in designated directories, making it easier to manage and organize data for AI workflows.
