# Perceived Exertion Converter MCP for AI Agents AI Agent Connect

> Perceived Exertion Converter turns your subjective effort into hard numbers. It maps your RPE (Borg or CR10 scales) to estimated heart rate, percentage of max capacity, and specific training zones like Aerobic or Threshold. It's built for athletes who need to track intensity without always wearing a heart rate monitor.

## Description

If you're training hard but don't have a heart rate monitor on your wrist, it's easy to lose track of whether you're actually hitting your target zones. This Connector fixes that by bridging the gap between how you feel and what your body is actually doing. Instead of guessing if that last set was too easy or just right, you can tell your agent how tired you feel on a standard scale. It'll then spit out your estimated heart rate, your percentage of max capacity, and exactly which training zone you're in. It even gives you coaching advice to help you adjust your intensity on the fly. You'll find this one in the Vinkius catalog alongside other tools that help turn subjective feedback into actionable data. It's about getting more consistent results without needing more gear. You get a clear picture of your workout intensity without the mental math.

## Tools

### convert_cr10_scale
Translates your CR10 effort level into physiological metrics like max capacity and heart rate. This helps you see your intensity as a percentage.

### get_training_guidance
Provides specific coaching advice and intensity descriptions based on your reported effort. It tells you what to do next based on how you feel.

### convert_borg_6_20_scale
Converts your Borg 6-20 effort rating into estimated heart rate and training zones. Use this to get data from a standard subjective scale.

## Prompt Examples

**Prompt:** 
```
I'm at a 15 on the Borg scale. My max HR is 195. What's my heart rate?
```

**Response:** 
```
Based on a Borg 6-20 score of 15 and a max HR of 195, here is your current status:

| Metric | Value |
| :--- | :--- |
| **Estimated Heart Rate** | ~161 BPM |
| **Training Zone** | Aerobic |
| **Intensity** | Moderate |

Keep your pace steady to stay within this zone.
```

**Prompt:** 
```
Convert a CR10 of 8 with a max HR of 180.
```

**Response:** 
```
For a CR10 effort of 8 and a max HR of 180, your estimated stats are:

* **Heart Rate:** ~144 BPM
* **Max Capacity:** 80%
* **Training Zone:** Threshold

You're hitting a solid intensity for a threshold workout.
```

**Prompt:** 
```
What should I do at an RPE of 19?
```

**Response:** 
```
An RPE of 19 represents very high intensity. 

* **Zone:** Anaerobic / Maximal
* **Characteristics:** Intense muscular effort, usually sustainable for very short durations.
* **Coaching Tip:** Focus on explosive power or high-intensity intervals. Don't attempt to maintain this level for long periods as it will lead to rapid fatigue.
```

## Capabilities

### Calculate heart rate from Borg scale
Get an estimated heart rate and training zone from a Borg 6-20 effort rating.

### Translate CR10 effort to metrics
Turn a CR10 scale score into your percentage of max capacity and specific training zones.

### Get real-time coaching advice
Receive qualitative intensity descriptions and practical tips based on your reported effort level.

### Identify specific training zones
See if your current effort lands you in the Aerobic, Threshold, or Anaerobic zones.

### Estimate max capacity percentage
Find out what percentage of your maximum capacity you're currently using.

## Use Cases

### Training without a watch
A runner feels tired and uses the Borg scale to see if they're still in the aerobic zone or if they need to back off.

### Gym progress tracking
A lifter uses CR10 to see if their intensity is high enough for hypertrophy or if they're coasting.

### Coaching advice
An athlete asks for guidance on what to do next after a high-effort set to avoid burning out.

### Zone checking
A cyclist wants to know their heart rate percentage during a steady state ride to ensure they stay on pace.

## Benefits

- Train without a heart rate monitor by using convert_borg_6_20_scale to get your stats.
- Get specific coaching advice from get_training_guidance to adjust your workout intensity.
- Know your exact training zone (Aerobic, Threshold, etc.) using convert_cr10_scale.
- Stay consistent with your training goals by turning 'how you feel' into data.
- Get immediate feedback on your max capacity percentage without manual calculations.

## How It Works

The bottom line is you get objective training metrics from your own subjective feedback.

1. Tell your agent your current effort level and your max heart rate.
2. Choose which scale you're using, like the Borg 6-20 or the CR10.
3. Get back your estimated heart rate, training zone, and coaching tips.

## Frequently Asked Questions

**How does the Perceived Exertion Converter work?**
It takes your subjective feeling of effort and converts it into estimated heart rate, training zones, and coaching advice using standard fitness scales.

**Can I use the Perceived Exertion Converter without a heart rate watch?**
Yes, that is exactly what it's for. It allows you to get data-driven insights even when you aren't wearing a heart rate monitor.

**What is the Borg scale used for in training?**
The Borg scale is a 6-20 scale used to rate how hard you are working. This Connector uses that rating to estimate your actual physiological output.

**How does this help me train more effectively?**
It helps you stay consistent. By turning 'how you feel' into a specific zone, you can ensure you're actually hitting your target goals for every workout.

**Is the heart rate estimation accurate?**
It provides a reliable estimate based on your reported effort and your max heart rate. It's a great way to stay in your zones without needing a chest strap.

**Can this Connector give me coaching tips?**
Yes, it provides qualitative descriptions and practical advice based on the effort level you report, helping you adjust your workout on the fly.

**What is the Borg 6-20 scale?**
The Borg 6-20 scale is a traditional method for measuring perceived physical exertion, where 6 represents no effort and 20 represents maximal intensity.

**How accurate are the heart rate estimates?**
The tool provides estimates based on the relative position of your RPE within the scale range applied to your maximum heart rate. It is a mathematical approximation for training guidance.

**Can I use this without a heart rate monitor?**
Yes, the primary purpose of these tools is to help you estimate intensity and training zones using only your subjective perception of effort.
