# Options Greeks Calculator MCP for AI Agents MCP

> Options Greeks Calculator uses the Black-Scholes model to calculate theoretical prices for Call and Put options. It quantifies complex market risks, letting you instantly measure how option values change based on underlying price movement, volatility, time decay, or interest rate shifts.

## Description

This MCP is a high-precision financial engine designed specifically for quantifying the risk inherent in European-style option positions using the Black-Scholes model. Instead of manually calculating sensitivity metrics across different market variables, your AI client accesses this tool to assess how underlying asset prices, volatility levels, time decay, and interest rates impact your portfolio's value. You can instantly gauge directional exposure by checking price movements, or you can determine theoretical fair values for Call and Put options. This level of granular risk assessment is vital for professional traders and quantitative analysts who need real-time data. Vinkius hosts this MCP within its catalog, giving your AI client access to a comprehensive suite of financial tools alongside the option Greeks calculator.

## Tools

### calculate_directional_risk
Shows how much an option price changes if the underlying asset's price moves.

### calculate_environmental_sensitivities
Measures how outside factors like time, volatility, and interest rates change the option’s value.

### calculate_option_valuation
Calculates Black-Scholes theoretical prices for both Call and Put options based on inputs.

## Prompt Examples

**Prompt:** 
```
What is the current theoretical value for a Call option if I use these parameters: underlying at 100, strike of 95, 3 months left, 25% volatility, and 4% interest rate?
```

**Response:** 
```
**Call Option Valuation Report**

| Metric | Value |
| :--- | :--- |
| Theoretical Price (Call) | $8.12 |
| Delta | 0.75 |
| Gamma | 0.03 |

This indicates a strong positive directional exposure to the underlying asset.
```

**Prompt:** 
```
If I hold an option, how much will its value decrease just due to time passing over the next week?
```

**Response:** 
```
Based on your parameters, the calculated Theta is -0.12. This means that, all else being equal, your option loses approximately $0.12 in theoretical value each day. Time decay is a significant factor here.
```

**Prompt:** 
```
Show me the total risk if volatility jumps to 35% and rates are 5%, assuming my current position.
```

**Response:** 
```
**Environmental Sensitivity Check**

*   **Impact of Volatility (Vega):** A jump to 35% would increase your option value by approximately $1.50.
*   **Impact of Rates (Rho):** The change in interest rates has a minor impact, shifting the value by about $0.25.

Overall risk is highly sensitive to changes in market volatility.
```

## Capabilities

### Assess directional price impact
Determines how much an option's value reacts when the underlying asset's price moves up or down.

### Measure external factor sensitivities
Quantifies how outside elements—like passing time, changes in volatility, or shifts in interest rates—affect the option’s theoretical value.

### Calculate theoretical option prices
Runs Black-Scholes calculations to provide estimated fair market values for both Call and Put options.

## Use Cases

### Stress-testing a new hedge position
A trader needs to know if their current option spread is safe from sudden volatility swings. They ask their agent to run the calculator, checking environmental sensitivities for Vega and Gamma against a simulated market shock.

### Calculating theoretical value for an audit
An analyst must provide a fair-market valuation for a large block of options expiring next month. They prompt their agent to run the calculation_option_valuation tool, generating verifiable Black-Scholes prices instantly.

### Assessing immediate price risk
A hedge fund manager gets an alert that the underlying asset is moving fast. They immediately ask the MCP for directional risk metrics to determine how aggressively their current options positions are exposed to rapid price changes.

## Benefits

- Pinpoint directional exposure. Instead of guessing how a price drop impacts your options, the calculator uses `calculate_directional_risk` to give you precise Delta and Gamma metrics.
- Understand market time decay. You can determine exactly how much value an option loses each day by running calculations for environmental sensitivities, which includes Theta.
- Model complex scenarios instantly. Need to know how a rate hike or volatility shift affects your trade? The MCP measures this via `calculate_environmental_sensitivities` in seconds.
- Get theoretical pricing immediately. Use the tool to perform black-scholes calculations and get estimated fair prices for both Call and Put options using `calculate_option_valuation`.
- Reduce modeling time dramatically. By centralizing all these complex calculations, you cut down hours of spreadsheet work into single AI prompts.

## How It Works

The bottom line is that you get instant, multi-variable risk reports without having to run complex financial models manually or through separate software.

1. Specify the parameters: you tell your AI client the underlying asset price, the strike price, time remaining until expiration, current volatility, risk-free rate, and whether it's a Call or Put option.
2. The MCP invokes the necessary financial models to process these variables against the Black-Scholes framework.
3. Your agent returns a detailed breakdown, providing not only the calculated theoretical price but also key metrics like Delta, Gamma, Theta, Vega, and Rho.

## Frequently Asked Questions

**How does the Options Greeks Calculator help me price options?**
It calculates the theoretical fair value for both Call and Put options using the Black-Scholes model. You input key market variables, and it gives you an estimate of what the option *should* cost based on established financial principles.

**Can this MCP tell me how much my trade is exposed to price changes?**
Yes. The calculator determines directional risk using Delta and Gamma metrics, which quantify exactly how much your options position will react if the underlying stock's price moves up or down.

**What are environmental sensitivities in the Options Greeks Calculator?**
This refers to external market factors. The MCP measures how things like time passing (Theta), volatility changes (Vega), or interest rate shifts (Rho) affect your option's value, giving you a holistic risk view.

**Is this tool only for advanced traders?**
No. While it handles complex models, the goal is to give clear answers. It takes highly technical inputs and outputs easy-to-understand metrics that help anyone assess market risk confidently.

**Does the Options Greeks Calculator handle different expiration dates?**
Yes. You can input varying time remaining until expiration, allowing you to compare how your options value changes as they approach their maturity date.
