Which integrations are available for this server?

Enables image analysis, OCR, image comparison, and video analysis using local vision models served by Ollama. Provides tools for image analysis, OCR, image comparison, and video analysis using OpenAI-compatible vision models.

How do I use Vision MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Vision MCP Server extract text from this image: receipt.jpg" 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.

🚀 Quick Start

1. Install

git clone https://github.com/Loveacup/vision-mcp-server.git
cd vision-mcp-server
npm install && npm run build

2. Configure

Create a .env file in the project root:

VISION_BASE_URL=http://your-server:port/v1/chat/completions
VISION_MODEL=Qwen3-VL-32B
VISION_API_KEY=your-api-key    # optional for local models

{
  "baseUrl": "http://your-server:port/v1/chat/completions",
  "model": "Qwen3-VL-32B",
  "apiKey": "your-api-key",
  "maxTokens": 4096,
  "temperature": 0.7
}

3. Run

npm start

The server communicates over stdio, designed to be launched by an MCP client such as Claude Code.

🔌 Claude Code Integration

Add to your ~/.mcp.json:

{
  "mcpServers": {
    "vision": {
      "command": "node",
      "args": ["/path/to/vision-mcp-server/dist/index.js"],
      "env": {
        "VISION_BASE_URL": "http://your-server:port/v1/chat/completions",
        "VISION_MODEL": "Qwen3-VL-32B",
        "VISION_API_KEY": "your-api-key"
      }
    }
  }
}

Replace /path/to/vision-mcp-server with the actual install path.
