AI Vision MCP Server: Visual Analysis Capabilities via Model Context Protocol

Overview: What is AI Vision MCP Server?

The AI Vision MCP Server is an MCP (Model Context Protocol) adapter that enables integration of AI-powered visual analysis tools with various AI applications through a standardized protocol. It enhances the capabilities of Claude Desktop and other compatible MCP clients by providing advanced features such as screenshot capture, UI analysis, file operations, report generation, and context maintenance across multiple steps.

🔧 Core Features & MCP Capabilities

The AI Vision MCP Server offers several key features that are critical for seamless integration with AI applications:

1. Screenshot URL: The server can capture screenshots of any specified website by accepting a URL. This functionality is powered by Playwright, which automates web browsers to ensure accurate and detailed screen captures.

2. Visual Analysis: Utilizing advanced AI vision techniques, the server analyzes UI elements, layouts, and content within captured screenshots. This analysis provides in-depth insights into visual components of web applications, ensuring that developers and analysts can quickly identify and resolve issues.

3. File Operations: The server supports reading from and editing files with precise line-level control. This capability allows for detailed modifications to text or code without affecting other parts of the document.

4. Report Generation: Based on the analysis performed, the server generates comprehensive UI/UX reports that can be used for documentation, feedback, or further development phases. These reports are structured and provide a clear understanding of the visual quality and usability aspects of an application.

5. Debugging Session Context: The server maintains context between different steps in the analysis process, ensuring that all operations performed remain consistent with previous analyses. This feature is particularly useful for iterative development cycles where multiple tests need to be conducted across various stages.

⚙️ MCP Architecture & Protocol Implementation

The AI Vision MCP Server adheres to the Model Context Protocol (MCP), which defines a standardized way of communicating between AI applications and external data sources or tools. The protocol ensures compatibility and ease of integration, making it simple for developers to add this server to their projects without extensive configuration.

The server architecture includes:

• MCP Client: Integration point between the AI application and the server.
• MCP Protocol: Standardized communication interface used by both the client and the server.
• Data Source/Tool: External resources that provide specific functionalities such as screenshot capture, content analysis, etc.

🚀 Getting Started with Installation

To get started, follow these steps to install and run the AI Vision MCP Server:

Prerequisites

• Node.js 14 or above
• Playwright for web automation
• Gemini API key for AI vision analysis

# Clone the repository
git clone https://github.com/samihalawa/mcp-server-ai-vision.git
cd mcp-server-ai-vision

# Install dependencies
npm install

# Build the server
npm run build

Starting the Server

Once installed, you can start the MCP server by running:

npm start

To integrate this server with your AI application’s MCP configuration, follow these steps:

Configuration

Add the server to your MCP configuration as shown below:

{
  "mcpServers": {
    "ai-vision": {
      "command": "/path/to/node",
      "args": ["/path/to/mcp-server-ai-vision/build/index.js"],
      "env": {
        "NODE_PATH": "/path/to/node_modules",
        "PATH": "/usr/local/bin:/usr/bin:/bin",
        "GEMINI_API_KEY": "your-gemini-api-key"
      }
    }
  }
}

This configuration ensures that your AI application can communicate with the MCP server using the correct paths and environment settings.

💡 Key Use Cases in AI Workflows

Workflow Scenario 1: Analyzing Website UI Elements

A web developer aims to improve the user experience of their website. They use the AI Vision MCP Server by integrating it into a custom development setup:

1. Capture Screenshot: Capture a screenshot from https://example.com using the screenshot_url(url: "https://example.com") command.
2. Analyze UI Elements: Use the analyze_screen() function to get detailed analysis of elements on the captured screen.
3. Generate Report: Using the results from step 2, generate a comprehensive report with generate_report().

Workflow Scenario 2: Debugging and Updating Documentation

A technical writer needs to ensure that documentation for an application is accurate and up-to-date. By incorporating the AI Vision MCP Server:

1. Capture Screenshot: Create a screenshot of the latest version of the application using screenshot_url(url: "https://app.example.com").
2. Generate Report: Extract key information from this screen to update documentation entries with relevant screenshots.
3. Modify Files: Use read_file and modify_file commands for precise updates to existing text files, ensuring every line is modified as needed.
