# Portfolio Volatility Calculator MCP for AI Agents AI Agent Connect

> Portfolio Volatility Calculator lets you calculate asset volatility, covariance, and portfolio risk metrics. It handles the heavy lifting of financial risk analysis so your AI client can give you precise data on how assets move together and where your biggest risks are hiding. Use it to get standalone volatility for individual stocks, generate full covariance matrices for asset pairs, and identify the primary drivers of risk in your portfolio.

## Description

Managing a portfolio means staying on top of how different assets behave when the market gets messy. Instead of manually pulling data into a spreadsheet and wrestling with complex variance formulas, this Connector handles the math for you. You can ask your agent to check how much an individual stock is swinging or see how a group of assets correlates. It digs into the covariance between every pair in your list to show you the hidden connections. When you need the big picture, it identifies which specific assets are driving your risk and which ones are actually providing the diversification you're looking for. It's built for people who need accurate risk modeling without the headache of manual calculations. By adding this to your setup through Vinkius, you give your AI client a professional-grade finance toolkit that turns raw data into actionable risk insights. You can quickly pivot from checking a single asset's volatility to viewing a full matrix of correlations, allowing for a much deeper understanding of your holdings. It removes the friction of manual data entry and replaces it with direct, queryable answers about your financial exposure. Whether you are balancing a conservative retirement fund or a high-growth tech basket, having these calculations ready at your fingertips changes how you approach every trade. It provides a clear, data-driven foundation for your strategy, ensuring that your moves are based on actual math rather than gut feelings.

## Tools

### get_asset_volatilities
Calculates the standalone volatility for every individual asset provided in the dataset. This is perfect for checking the risk of a single stock or bond.

### get_covariance_matrix
Generates a matrix showing the covariance between every possible pair of amounts in the portfolio. Use this to find hidden correlations between different asset classes.

### analyze_portfolio_risk
Calculates aggregate portfolio risk and identifies the primary drivers of risk and diversification. Use this to see what's actually moving your risk needle.

## Prompt Examples

**Prompt:** 
```
What's the volatility for these two stocks with returns [[0.01, 0.02], [-0.01, 0.03]]?
```

**Response:** 
```
Based on those returns, here is the individual volatility for each asset:

- **Stock A**: 0.0141
- **Stock B**: 0.0212

Both assets show different risk profiles, with Stock B exhibiting higher volatility.
```

**Prompt:** 
```
Calculate the risk for a portfolio of Apple (0.6 weight) and Microsoft (0.4 weight) using this covariance: {'Apple|Apple': 0.0002, 'Microsoft|Microsoft': 0.0004, 'Apple|Microsoft': 0.0001}
```

**Response:** 
```
The total portfolio volatility is **0.0155**.

Here is the breakdown:
- **Highest Risk Adder**: Apple
- **Highest Diversifier**: Microsoft

This shows that while Apple contributes more to the overall risk, Microsoft is doing the heavy lifting for diversification.
```

**Prompt:** 
```
Show me the covariance between Asset A and Asset B with returns [[0.01, 0.02], [0.01, 0.02]].
```

**Response:** 
```
The covariance between Asset A and Asset B is **0.0001**. This figure helps you understand how closely these two assets move in tandem.
```

## Capabilities

### Calculate standalone volatility
Get the risk profile for every individual asset in your dataset instantly.

### Generate covariance matrices
See how every possible pair of assets in your portfolio moves in relation to each other.

### Identify risk drivers
Pinpoint the specific assets that are contributing the most to your overall portfolio risk.

### Determine aggregate risk
Get a single, clear metric for the total risk of your entire investment portfolio.

### Analyze diversification
Check if your portfolio is truly diversified or if you're over-exposed to the same underlying trends.

## Use Cases

### Checking for over-exposure to a specific stock
An analyst wants to see if adding a new tech stock makes the portfolio too volatile. The agent uses `get_asset_volatilities` to check the swing and `analyze_portfolio_risk` to see the new total risk.

### Finding hidden correlations in a diverse basket
A manager needs to know if two different stocks move too closely together. The agent runs `get_covariance_matrix` to find the correlation between specific pairs of assets.

### Identifying the source of a portfolio drop
A user wants to know why their portfolio is down despite having many different holdings. The agent uses `analyze_portfolio_risk` to pinpoint the primary risk drivers.

### Stress testing new investment ideas
A trader wants to see the risk of a new group of assets. The agent calculates the aggregate volatility of the entire group instantly to see if it fits the risk profile.

## Benefits

- Stop wasting time on manual variance math by using `get_asset_volatilities` to get instant data on individual assets. This lets you see the risk profile of every stock or bond in your list without opening a single spreadsheet.
- See hidden correlations between assets with a full covariance matrix from `get_covariance_matrix`. It maps out how every possible pair in your portfolio moves together, highlighting potential overlapping risks you might otherwise miss.
- Identify exactly which assets are causing the most trouble using `analyze_portfolio_risk`. This tool pinpoints the primary drivers of your risk, so you know exactly which positions need your attention and which ones are performing well.
- Get a clear view of your diversification to ensure your portfolio isn't over-concentrated in one area. The Connector analyzes your asset mix to confirm if your diversification is real or if you're just holding different names of the same underlying risk.
- Make faster investment decisions by having your agent provide real-time risk metrics. Instead of waiting for a weekly report, you can ask your AI client to run a quick risk check on a new asset class the moment you consider adding it.

## How It Works

The bottom line is you get professional risk analysis without having to build the math yourself.

1. Provide your AI client with a list of assets and their historical returns.
2. Ask the agent to calculate specific metrics like covariance or aggregate risk.
3. Receive a detailed breakdown of risk drivers and portfolio volatility.

## Frequently Asked Questions
