## Description

You can use this MCP to run precise hydrodynamic simulations for surfboard design and performance testing. Instead of guessing how a new rail profile or fin setup will behave, you can feed your board's geometry and intended speed into your AI client to get hard numbers. It handles the heavy lifting of calculating turning paths, the gravitational load on a rider during a carve, and the specific trajectory of water spray. Whether you are modeling a new rocker profile or testing how a specific mass affects turn intensity, this MCP gives your agent the physics engine it needs to provide accurate performance predictions.

## Tools

### calculate_carve_radius
This tool determines the primary turning radius of the board. It uses rider input and board geometry to find the path.

### calculate_turn_gforce
This tool calculates the physical gravitational load. It tells you the G-force a rider experiences during a carve.

### get_optimized_configuration
This tool recommends equipment setups. It suggests the ideal fin setup or rocker to hit a target radius.

### simulate_spray_trajectory
This tool predicts water displacement. It models the visual pattern and direction of the spray kicked up by the rail.

## Prompt Examples

**Prompt:** 
```
What is the turning radius for a 180cm board at 5m/s with a 30 degree edge angle and a thruster fin setup?
```

**Response:** 
```
The calculated turning radius is 3.45 meters with a stability score of 0.82.
```

**Prompt:** 
```
How much G-force will I feel if I carve at 6m/s with a 2.5 meter radius and a total mass of 85kg?
```

**Response:** 
```
You will experience a G-force of 1.48, which is categorized as moderate load intensity.
```

**Prompt:** 
```
Predict the spray pattern for a hard rail at 4m/s with a high rocker profile and 45 degree edge angle.
```

**Response:** 
```
The spray will reach a height of 0.85 meters at a 35 degree angle with high volume intensity.
```

## Capabilities

### Turning Path Modeling
Your agent uses this to find the exact radius of a board's carve.

## How It Works

Get physics-driven surfboard data in your AI client in four steps.

1. Connect your AI client to the Vinkius hosted MCP.
2. Provide board geometry, speed, or rider mass to your agent.
3. The agent calls the specific physics tool needed for the calculation.
4. Receive precise numerical results for radius, G-force, or spray patterns.

## Frequently Asked Questions

**What kind of physics does this MCP handle?**
It handles hydrodynamic and planing hull physics, specifically focusing on turning radii, G-forces, and water spray trajectories.

**Can I use this with Claude or Cursor?**
Yes, you can use this with any MCP-compatible client like Claude, Cursor, or Windsurf once you connect it via Vinkius.

**How does it recommend equipment?**
The get_optimized_configuration tool analyzes your target radius to suggest the best fin setup or rocker profile.

**Do I need to host the physics engine myself?**
No, Vinkius hosts and manages the MCP, so it is ready to use immediately after you connect.

**What inputs are required for a carve calculation?**
You typically need to provide board geometry, rider input, and speed to get an accurate turning radius.
