# Backside Spin Mechanics Analyzer AI Agent Connect

> Backside Spin Mechanics Analyzer uses physics-based modeling to help you understand the mechanics of backside rotations. It calculates takeoff momentum, predicts how different grabs affect your spin axis, and evaluates landing stability to help you prepare for high-consequence maneuvers.

## Description

You can use this MCP to run physics simulations on your freestyle snowboard tricks. Instead of guessing if you have enough speed or if a specific grab will throw off your axis, you can feed your approach data into your AI client to get hard numbers. The engine looks at your approach speed, the angle of your takeoff edge, and your body rotation to determine exactly how you will behave in the air. 

If you are working on a new backside rotation, you can model the entire flight path. You can check how much edge pressure you need to generate the right momentum or how an Indy grab versus a Melon grab changes your rotation speed. It even helps you assess the risk of blind landings by calculating stability ratings. It is a technical tool for anyone who wants to move from intuition to calculated execution in their freestyle riding.

## Tools

### analyze_takeoff_dynamics
This tool calculates the initial forces and rotational impulses generated during your takeoff.

### calculate_rotation_profile
Use this to determine your predicted spin axis and rotation speed based on specific grab types.

### evaluate_landing_safety
This tool assesses the stability and risk level of your landing.

### simulate_full_maneuver
This provides a complete overview of the entire backside spin attempt from takeoff to landing.

## Prompt Examples

**Prompt:** 
```
Analyze a takeoff with 8 m/s speed, 15 degree edge angle, and 50 units of body rotation.
```

**Response:** 
```
The required edge pressure is 45.2 N, providing an initial angular momentum of 120.5 and a linear takeoff trajectory.
```

**Prompt:** 
```
How will an Indy grab affect my rotation if my momentum is 100?
```

**Response:** 
```
With an Indy grab, your rotation axis will be diagonal, your rotation speed will be 12.5 rad/s, and your stability rating is 8.5.
```

**Prompt:** 
```
Will I land safely with a rotation speed of 15 and a Melon grab during a blind landing?
```

**Response:** 
```
Your landing stability is 4.2, which is considered Moderate risk. It is recommended to open your chest earlier to spot the landing.
```

## Capabilities

### Takeoff Force Calculation
Your agent uses this to find the necessary edge pressure and momentum for a specific approach.

### Spin Axis Prediction
The AI calculates how different grab styles shift your center of mass and rotation axis.

### Landing Risk Assessment
Your client evaluates stability ratings to predict if a landing will be smooth or unstable.

### Full Flight Simulation
The MCP runs a complete sequence from the initial edge engagement to the final landing impact.

## Use Cases

### Optimizing Takeoffs
Calculate the exact edge angle and speed needed to clear a specific jump height.

### Grab Selection
Compare how an Indy grab versus a Melon grab changes your rotation speed.

### Safety Checks
Run a simulation to see if your rotation speed makes a blind landing too unstable.

### Trick Progression
Model a full maneuver to understand the relationship between momentum and rotation.

## Benefits

- Reduces guesswork by providing specific Newton and rad/s values for rotations.
- Identifies landing risks before you attempt a high-consequence maneuver.
- Shows how different grab types physically alter your flight path.
- Provides a mathematical basis for improving takeoff edge pressure.

## How It Works

Connect your AI client to Vinkius to start running physics simulations immediately.

1. Connect your MCP-compatible client to the Vinkius hosted environment.
2. Provide your approach data like speed, edge angle, and rotation units to your agent.
3. The agent calls the specific physics tools within the MCP.
4. Receive calculated values for momentum, axis, and landing stability.

## Frequently Asked Questions

**What kind of data do I need for a takeoff analysis?**
You should provide your approach speed, the angle of your takeoff edge, and your body rotation units.

**Can this MCP predict how a grab changes my spin?**
Yes, the rotation profile tool calculates how different grabs affect your spin axis and rotation speed.

**How does it determine landing safety?**
The tool assesses stability ratings based on your rotation speed and the type of grab used during the flight.

**Which AI clients can I use with this MCP?**
You can use any MCP-compatible client like Claude, Cursor, or Windsurf.

**Do I need to host this myself?**
No, Vinkius hosts the MCP and manages everything so you can use it with one click.

**How does the grab type affect my rotation?**
The grab type changes your moment of inertia. Using `calculate_rotation_profile` will show how different grabs like Indy or Melon affect your rotation speed and axis.

**Can I simulate a whole jump at once?**
Yes, you can use the `simulate_full_maneuver` tool to get a complete breakdown of takeoff, rotation, and landing in one go.

**What determines my landing stability?**
Landing stability is determined by your rotation speed and the difficulty of the blind landing. You can check this using `evaluate_landing_safety`.
