Provides AI vision analysis using Google Gemini models, enabling image understanding, OCR, error diagnosis, chart analysis, and UI design evaluation.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-vision-analyze What's shown in this screenshot?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
A lightweight Model Context Protocol (MCP) server that provides AI vision analysis capabilities. Analyze images using Google's Gemini models via OpenRouter.
Works with: Claude Desktop, Claude Code CLI, Antigravity, Cursor, Pi Agent, Windsurf, Cline, VS Code, and any MCP-compatible client.
🖼️ Analyze images from local file paths or HTTP(S) URLs
🧠 Powered by Google Gemini models (2.5 Flash Lite, 3 Flash Preview, etc.)
💰 Ultra cheap — ~$0.001 per image with Gemini 2.5 Flash Lite
📝 Extract text from screenshots (OCR)
🐛 Diagnose error messages in screenshots
📊 Analyze charts, diagrams, and UI designs
🔒 Secure — API key stays local, never sent anywhere except OpenRouter

The MCP server itself is free and open-source. The Gemini models on OpenRouter are paid but very cheap (~$0.001 per image).
Currently supports OpenRouter models. You can change VISION_MODEL to any model available on OpenRouter that supports vision (GPT-4o, Claude, etc.).
No. It requires an internet connection to call the OpenRouter API.
No. Images are processed in-memory and sent directly to OpenRouter's API. Nothing is stored on disk (except temporary files that are auto-cleaned).
