mcp-video-analyser

A stdio-based MCP (Model Context Protocol) server for video analysis using Google Gemini and Moonshot Kimi AI.

Features

• Analyze video files with AI vision models
• Support for multiple providers: Google Gemini and Moonshot Kimi
• Interactive setup wizard for easy configuration
• User-scope or project-scope configuration
• Environment variable support with fallback defaults
• Video file validation (format, size, magic bytes)
• TypeScript with strict type checking

Installation

npm install -g mcp-video-analyser
# or
bun install -g mcp-video-analyser

Quick Start

1. Run Setup

mcp-video-analyser setup

This will guide you through configuring your providers and API keys.

2. Configure Your MCP Client

Add to your MCP client configuration (e.g., Claude Desktop):

{
  "mcpServers": {
    "mcp-video-analyser": {
      "command": "mcp-video-analyser",
      "env": {
        "GOOGLE_API_KEY": "your-google-api-key",
        "MOONSHOT_API_KEY": "your-moonshot-api-key"
      }
    }
  }
}

3. Use the Tools

The server provides these MCP tools:

• analyze_video - Analyze a local video file with an AI prompt
• list_providers - List available providers and their models
• get_config - View current configuration (API keys masked)
