## Description

You know that feeling when you look at your electricity bill and wonder where all the money went? A lot of it is from electronics drawing power just to stay 'ready.' This MCP lets you stop guessing about vampire draw. You can first browse a full catalog of common appliances, checking out their specific standby wattage. From there, you calculate the exact monthly cost for any single device, like your TV or gaming console. Finally, if you want the big picture—the total impact across ten different gadgets—you run an aggregate report. It pulls together all that waste data to give you a combined energy usage number, the expected annual bill increase, and the CO2 emissions. When you connect this MCP via Vinkius, your agent handles the math, giving you clear numbers instead of vague estimates.

## Tools

### calculate_single_device_waste
Calculates the monthly energy waste and financial cost for a single, specified electronic device.

### fetch_device_catalog
Returns a list of common electronics and their estimated power consumption in Watts.

### generate_aggregate_waste_report
Creates one total report summarizing the combined energy waste, cost, and CO2 emissions for all selected devices.

## Prompt Examples

**Prompt:** 
```
Show me a list of available devices.
```

**Response:** 
```
Running `fetch_device_catalog` would return a list of electronics like Televisions, Gaming Consoles, and Microwaves with their standby power ratings.
```

**Prompt:** 
```
How much does my TV cost me in standby energy per month?
```

**Response:** 
```
By using `calculate_single_device_waste` for your Television, you can determine the monthly kWh usage and the specific financial cost based on your local electricity rate.
```

**Prompt:** 
```
Calculate the total waste for a Laptop Dock (5 hours/day) and a Smart Speaker (24 hours/day).
```

**Response:** 
```
The `generate_aggregate_waste_report` tool would process these devices to provide the total monthly energy consumption, annual cost, and CO2 emissions.
```

## Capabilities

### Cataloging Devices
Retrieves a list of available electronics along with their estimated standby wattage ratings.

### Calculating Single Device Costs
Determines the monthly energy usage and financial cost for one specific appliance based on its power draw.

### Generating Total Waste Reports
Compiles a single report showing the combined total waste, annual cost, and CO2 footprint for multiple listed devices.

## Use Cases

### Pre-Sale Home Audit
A homeowner needs to calculate total waste before selling. They ask their agent to first run `fetch_device_catalog` for all major rooms, then use the data to estimate the combined annual cost and CO2 emissions from everything left plugged in.

### Optimizing Office Power Draw
A facility manager needs to know the baseline power drain of a specific server room setup. They run `calculate_single_device_waste` for each monitor, docking station, and mini-fridge to identify which piece of equipment is most inefficient.

### Event Exit Checklist
An event coordinator needs a quick estimate of waste when leaving a large hall. They use the agent to process a list of 20 different types of electronics (projectors, sound systems) through `generate_aggregate_waste_report` for an instant total.

### Comparing Appliance Models
A buyer is deciding between two brands of smart TVs. They use the agent to run `calculate_single_device_waste` on both models using the same usage hours, allowing them to compare the financial cost differences directly.

## Benefits

- Stop guessing about your bill. Instead of just knowing you waste energy, use `calculate_single_device_waste` to see the exact monthly kWh usage and dollar cost for any appliance.
- Get a complete inventory picture instantly. Run `fetch_device_catalog` once to get wattage data on dozens of devices without having to look up specs individually.
- Create one final, actionable report. The `generate_aggregate_waste_report` combines everything—total waste, annual cost, and CO2 footprint—into a single document for easy review.
- Pinpoint the biggest culprits. By breaking down consumption using individual device calculations, you find out which appliance needs attention first.
- Improve sustainability reporting. You can quantify not just the cost in dollars, but also the associated carbon emissions (CO2) from standby power.

## How It Works

The bottom line is: it turns vague electronic standby drain into clear financial and environmental metrics.

1. Ask your agent to retrieve the full list of electronics you own using the device catalog.
2. Select specific items and calculate the monthly waste impact for each one individually.
3. Submit all calculated data points to generate a single, consolidated report summarizing total energy usage and carbon emissions.

## Frequently Asked Questions

**How does `fetch_device_catalog` help me start an audit?**
It gives you the necessary starting point. Instead of looking up wattage for every device, this tool returns a list of common electronics and their estimated power draw right away.

**I only want to know the cost for my TV; do I need `calculate_single_device_waste`?**
Yes. This specific tool calculates the monthly energy consumption, financial cost, and CO2 footprint solely for your television set, giving you a focused number.

**Can I use `generate_aggregate_waste_report` if my devices are in different rooms?**
Yes. The tool doesn't care about location; it only processes the data points and wattage figures you provide to calculate a single, combined total for all your listed electronics.

**Is this MCP just for calculating energy waste or does it help with carbon footprint?**
It handles both. The final report generated by `generate_aggregate_waste_report` includes the total CO2 emissions alongside the dollar cost, giving you a full environmental and financial picture.

**When I run `calculate_single_device_waste`, can I input my own local electricity rate?**
Yes, you specify the rate directly in the tool's parameters. The MCP lets you override default assumptions for both cost and kilowatt-hour rates. This makes sure your financial calculation matches your actual utility bill.

**Does `generate_aggregate_waste_report` have limits on how many devices I can include in one report?**
The tool is designed for comprehensive auditing and handles hundreds of listed items. If you hit a very large dataset limit, your agent will prompt you to break the calculation into smaller groups.

**If I use `fetch_device_catalog` and find a device not in the list, how do I proceed with my calculations?**
You must manually provide the wattage for that specific appliance. You can then feed those custom figures into `calculate_single_device_waste` to continue your audit without interruption.

**Are the usage patterns reported by `generate_aggregate_waste_report` kept private?**
Your energy consumption data remains confidential. The MCP processes and generates reports using only the inputs you provide through your AI client, ensuring no external tracking occurs.

**What is vampire power?**
Vampire power refers to the electricity consumed by devices while they are in standby mode or switched off but still plugged in.

**How can I see which devices use the most energy?**
You can use the `fetch_device_catalog` tool to view a list of common electronics and their estimated standby wattage.

**Can I calculate the total impact for all my devices at once?**
Yes, the `generate_aggregate_waste_report` tool allows you to input multiple devices to see your cumulative monthly energy waste and annual carbon footprint.
