3D Visualizer MCP Server

View, compare and inspect point clouds, meshes, gaussian splats, depth maps and disparity images in your editor or browser - with Rust and WebAssembly doing the heavy decoding, so files with millions of points open in seconds. It runs locally over stdio via the published package.

People who work with 3d visualization, colmap and depth estimation and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install 3D Visualizer

Claude Code

claude mcp add kleinicke-ply-visualizer -- uvx 3d-visualizer

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "kleinicke-ply-visualizer": {
      "command": "uvx",
      "args": [
        "3d-visualizer"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
