## Description

When you're working with complex digital assets, you can't just assume a mesh is perfect. This MCP gives your AI client the tools to analyze 3D triangular meshes down to their fundamental structure. You can calculate real-world metrics like volume and surface area, which is essential for physics simulations or resource management. It also tells you how much space an asset occupies by computing its spatial boundaries—things like Axis-Aligned Bounding Boxes and bounding spheres. Beyond size, the calculator checks the mesh's integrity. It confirms if the geometry is manifold, ensuring that every edge is correctly connected to guarantee clean simulation results. If your workflow demands reliable geometric data, connecting this MCP via Vinkius gives your agents immediate access to these specialized calculations.

## Tools

### get_mesh_enclosures
Calculates the Axis-Aligned Bounding Box (AABB) and the minimal bounding sphere that contains the entire mesh.

### get_mesh_metrics
Computes critical physical properties: surface area, enclosed volume, and the center of mass for a given mesh.

### get_mesh_topology
Analyzes mesh connectivity to determine if the geometry is manifold and calculates weighted vertex normals for accurate shading.

## Prompt Examples

**Prompt:** 
```
What are the total volume and surface area for these vertices?

## Capabilities

### Determine physical size and mass metrics
Calculate the total surface area, enclosed volume, and center of mass for any given mesh.

### Define accurate spatial boundaries
Compute the minimum bounding box (AABB) and the smallest possible enclosing sphere for a 3D asset.

### Analyze structural integrity and connectivity
Assess if the mesh is topologically sound, detecting manifold geometry and calculating weighted vertex normals.

## Use Cases

### Checking asset readiness for a game engine
A developer needs to know if all environmental props passed into the game are collision-ready. They ask their agent to run get_mesh_enclosures on 50 assets, getting immediate AABB and bounding sphere data for optimized collision meshes.

### Estimating material volume for a sculpture
A sculptor needs to know the exact capacity of a complex, organic shape. They run get_mesh_metrics, which returns a precise volume measurement, allowing them to order the correct amount of resin or filler.

### Debugging CAD models for leakage
An engineering team suspects their simulated pipe network has gaps. Using get_mesh_topology, they verify if the mesh is truly manifold and identify exactly where edges are only used by one face, pointing out structural leaks.

### Verifying physics simulation boundaries
A researcher needs to calculate the total gravitational influence of a complex object. They use get_mesh_metrics to get the center of mass and surface area, ensuring their simulation's physical constants are correct.

## Benefits

- Accurate Volume and Surface Area: Instead of guessing, you use get_mesh_metrics to calculate exact volumes and surface areas needed for physics or material estimates.
- Optimized Collision Detection: Using get_mesh_enclosures, your agent instantly gets the AABB and bounding sphere data required for faster, more reliable collision checks in games.
- Structural Validation: The ability to run get_mesh_topology confirms if a mesh is truly manifold, saving hours of debugging time caused by faulty geometry.
- Center of Mass Calculation: Get precise center-of-mass coordinates using get_mesh_metrics, which is vital for simulating realistic physics interactions in your models.
- Fast Connectivity Checks: Quickly analyze the mesh structure with get_mesh_topology to ensure vertices and edges are connected correctly before export.

## How It Works

The bottom line is that your agent gets precise, calculated data about the mesh's size and structure without you needing to run complex external geometry software.

1. Your AI client sends the mesh data (vertices and indices) to this MCP.
2. You specify exactly what analysis you need—for instance, just the bounding box, or full volume metrics.
3. The MCP executes the calculation and returns a clean, structured set of geometric measurements.
