# School Grade Average Engine MCP. AI Agent Connect

> School Grade Average Engine is a specialized calculation tool for academic performance. It gives your AI client the ability to compute weighted and unweighted averages, check if grade weights are correct, and ensure all scores stay within valid academic ranges.

## Overview

## Description

Calculating academic averages manually is tedious and prone to error. This MCP gives your AI agent a dedicated math engine to handle the heavy lifting of gradebook management. Instead of relying on the AI to guess math results, you can use these tools to get exact weighted averages and verify that your grading scales are mathematically sound. You can check how a single assignment affects a total grade or confirm that a set of scores doesn't exceed the allowed limits. It's built to handle the specific logic required for school grading, from simple means to complex weighted distributions.

## Tools

### calculate_average
This tool computes the final average grade based on a specific set of assessments.

### get_grade_contribution
Use this to see exactly how much a single grade impacts the total weighted average.

### validate_grade_bounds
This tool checks that all submitted grades fall within a valid academic range.

### verify_weight_distribution
This tool confirms that provided weights follow a specific distribution or hit a target sum.

## Prompt Examples

**Prompt:** 
```
What is the average of grades 80, 90, and 70?
```

**Response:** 
```
The average grade is 80.
```

**Prompt:** 
```
Calculate the weighted average for grades 90 and 80 with weights 0.7 and 0.3.
```

**Response:** 
```
The weighted average is 87.0, with a total weight of 1.0.
```

**Prompt:** 
```
Are the grades [95, 105, 85] valid for a range of 0 to 100?
```

**Response:** 
```
No, the grade 105 is out of bounds.
```

## Capabilities

### Weighted Average Math
Your agent uses this to calculate final grades when assignments have different values.

### Weight Verification
The AI uses this to make sure grading weights add up to the correct total.

### Score Validation
Your agent checks if any entered grades fall outside of the allowed academic range.

### Impact Analysis
The AI calculates how much a specific test or project changes a student's overall grade.

## Use Cases

### Final Grade Calculation
An agent calculates a student's end-of-term grade using various weighted assignments.

### Gradebook Auditing
The AI checks a list of grades to ensure no scores are impossible or out of range.

### Syllabus Planning
A user verifies that their planned assignment weights sum to exactly 1.0.

### Student Performance Queries
A teacher asks the agent how much a upcoming final exam will move a student's current average.

## Benefits

- Eliminates math errors in weighted grade calculations.
- Prevents invalid data entry by checking grade bounds.
- Provides instant insight into how individual assignments affect totals.
- Ensures grading weights are mathematically consistent.

## How It Works

Connect the MCP to your client and let your agent handle the math.

1. Connect your preferred MCP-compatible client to Vinkius.
2. The agent detects the available grading tools.
3. You provide the grades or weights in a natural language prompt.
4. The agent executes the specific calculation tool.
5. You receive the precise mathematical result.

## Frequently Asked Questions

**Can this MCP handle weighted averages?**
Yes, it includes specific tools to calculate weighted averages and verify weight distributions.

**How do I use this with Claude or Cursor?**
You connect your client to Vinkius once, and the tools become available to your agent in those environments.

**Does it check for invalid grades?**
Yes, the validate_grade_bounds tool ensures all scores stay within your defined academic range.

**Can I see the impact of one specific test?**
Yes, the get_grade_contribution tool determines the individual impact of a single grade on the total.

**Do I need to host this myself?**
No, Vinkius hosts and manages the MCP so it is ready to use immediately upon connection.

**How do I calculate a weighted average?**
Provide the list of grades and a corresponding list of weights to the `calculate_average` tool.

**Can I check if my grades are within a valid range?**
Yes, use the `validate_grade_bounds` tool to ensure all scores fall between your specified minimum and maximum values.

**What happens if I don't provide weights?**
If no weights are provided, the `calculate_average` tool treats every grade as having an equal weight of one.
