Claude Computer Use Coordinate Normalizer MCP Connector for Claude

Transforms absolute pixel coordinates into the standardized 1024x768 viewport space for Anthropic's Computer Use API.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides a deterministic utility to bridge the gap between varying physical screen resolutions and the fixed virtual viewport required by Anthropic's Computer Use API. By using tools like calculate_coordinate, verify_dimensions, and get_viewport_constants, AI agents can accurately map interaction points from any resolution (e.g., 1920x10Far or 4K) into the standard 1024x768 coordinate space. The server handles proportional scaling, boundary clamping using V8 Math operations, and dimension validation to ensure every interaction point is precisely placed within the target viewport boundaries.

I have a 1920x1080 screen and I want to click at pixel (960, 540). What is the normalized coordinate?

The normalized coordinates are X: 512 and Y: 384.

Check if a resolution of 0x0 is valid for processing.

The dimension validation failed because the width and height must be greater than zero.

What are the standard viewport boundaries for this API?

The maximum width is 1024 and the maximum height is 768.

It takes your screen width, height, and target X/Y pixels to calculate the corresponding normalized coordinates within the 1024x768 space.
