cloudcompare-mcp

Cross-platform Model Context Protocol (MCP) server for CloudCompare — lets AI assistants (Claude, etc.) process 3D point clouds and meshes via natural language.

Features

Tool

Description

get_cloudcompare_info

Check installation & version

load_cloud_info

Inspect file stats (points, bounding box, scalar fields)

subsample

Reduce density — random / spatial / octree

compute_cloud_to_cloud_distances

C2C nearest-neighbour distances

compute_cloud_to_mesh_distances

C2M signed distances

icp_registration

Align two clouds with ICP

compute_normals

Estimate surface normals

filter_by_scalar_field

Threshold points by scalar value

statistical_outlier_removal

Remove noise with SOR filter

merge_clouds

Merge multiple clouds into one

convert_format

Convert between LAS/LAZ, PLY, PCD, XYZ, E57, OBJ…

run_cloudcompare_command

Escape hatch for arbitrary CLI commands

Requirements

  • CloudCompare ≥ 2.12 — download

  • Python ≥ 3.10

  • uv (recommended) or pip

Installation

Quickstart with uvx (no install needed)

uvx cloudcompare-mcp

Install locally

pip install cloudcompare-mcp
cloudcompare-mcp

CloudCompare binary detection

The server looks for CloudCompare in this order:

  1. CLOUDCOMPARE_PATH environment variable

  2. System PATH (cloudcompare / CloudCompare)

  3. Platform default locations:

Platform

Default path

macOS

/Applications/CloudCompare.app/Contents/MacOS/CloudCompare

Windows

C:\Program Files\CloudCompare\cloudcompare.exe

Linux

/usr/bin/cloudcompare

Set CLOUDCOMPARE_PATH to override:

export CLOUDCOMPARE_PATH="/opt/custom/cloudcompare"

MCP client configuration

Claude Desktop (claude_desktop_config.json)

{
  "mcpServers": {
    "cloudcompare": {
      "command": "uvx",
      "args": ["cloudcompare-mcp"]
    }
  }
}

Claude Code (~/.claude/settings.json)

{
  "mcpServers": {
    "cloudcompare": {
      "command": "uvx",
      "args": ["cloudcompare-mcp"]
    }
  }
}

With a custom binary path:

{
  "mcpServers": {
    "cloudcompare": {
      "command": "uvx",
      "args": ["cloudcompare-mcp"],
      "env": {
        "CLOUDCOMPARE_PATH": "/path/to/cloudcompare"
      }
    }
  }
}

Usage example

Once configured in Claude Desktop or Claude Code:

"Load my scan.las file and subsample it spatially to 5 cm, then remove statistical outliers."

Claude will call the appropriate tools in sequence and report results.

Supported file formats

LAS · LAZ · PLY · PCD · XYZ · ASC · TXT · E57 · OBJ · BIN · SHP
