Filter Amazon keywords by product image similarity using AI vision analysis with MCP (zai-mcp-server). Searches Amazon, merges product images into grids, then uses MCP to analyze visual features (color, style, material, shape) for intelligent matching. Use for filtering keywords from Seller Sprite Excel files, analyzing product similarity with AI instead of perceptual hashing, batch processing keywords with semantic visual understanding, and reducing MCP calls by merging images (10+ calls becomes 2 calls per keyword).
