# Currency Converter MCP for precise math. AI Agent Connect

> Currency Converter MCP provides the mathematical logic your agent needs to handle money. It handles everything from standard conversions to validating ISO currency codes and calculating inverse rates. Instead of letting your AI guess at math, this MCP gives it the specific tools to perform exact financial calculations on demand.

## Description

You can stop worrying about your AI client hallucinating exchange rates or failing at basic currency math. This MCP gives your agent a set of reliable tools to handle monetary conversions with precision. If you're building workflows that involve international pricing, budget tracking, or financial reporting, you need a way to ensure the math is actually correct. 

This MCP works by providing specific functions for common financial tasks. Your agent can check if a currency code is valid before attempting a calculation, look up supported identifiers, or flip an exchange rate to find the reciprocal. It acts as a dedicated math engine for currency, ensuring that every conversion follows strict logic rather than probabilistic guessing. You connect it once to your preferred MCP-compatible client and it's ready to work.

## Tools

### calculate_inverse_rate
This tool finds the reciprocal exchange rate. It determines what the rate would be if you swapped the source and target currencies.

### convert_currency
This tool performs the actual math for monetary conversions. It uses a provided rate to change an amount from one currency to another.

### get_supported_currencies
This tool returns a list of all currency identifiers the system recognizes. Use it to see which codes are available for use.

### validate_currency_code
This tool checks if a string follows standard ISO formatting. It ensures your agent is using valid international currency identifiers.

## Prompt Examples

**Prompt:** 
```
Convert 100 USD to EUR using an exchange rate of 0.92.
```

**Response:** 
```
100 USD is equal to 92 EUR.
```

**Prompt:** 
```
Is 'US' a valid currency code?
```

**Response:** 
```
No, 'US' is not a valid currency code. Valid codes must be exactly three alphabetic characters.
```

**Prompt:** 
```
What is the inverse of an exchange rate of 1.25?
```

**Response:** 
```
The inverse exchange rate is 0.8.
```

## Capabilities

### Exact Math
Your agent uses this to perform specific monetary conversions instead of estimating.

### Code Validation
The agent checks currency strings against ISO standards to prevent errors.

### Rate Reciprocals
Your agent calculates inverse rates when you need to flip the direction of an exchange.

### Currency Discovery
The agent pulls a list of supported currency codes to verify what it can work with.

## Use Cases

### International Pricing
An agent converts product prices from a base currency to multiple target currencies for global storefronts.

### Budget Auditing
Your agent uses the conversion tool to normalize different currency expenses into a single reporting currency.

### Data Cleaning
The agent uses validation to scrub a list of currency codes to ensure they are all valid ISO identifiers.

### Forex Math
An agent calculates inverse rates to quickly switch between direct and indirect exchange perspectives.

## Benefits

- Eliminates mathematical hallucinations in financial tasks.
- Ensures currency codes meet international standards.
- Provides a direct way to calculate reciprocal rates.
- Reduces errors by validating identifiers before processing.

## Frequently Asked Questions

**How do I use this MCP in Claude?**
You connect to the Vinkius catalog once, and the tools become available to your AI client immediately.

**Does this MCP handle the exchange rates itself?**
The conversion tool uses a provided rate to perform the math, ensuring the agent controls the specific rate used.

**Can it check if a currency code is correct?**
Yes, the validate_currency_code tool checks if a string follows standard ISO formatting.

**What happens if I use an invalid currency code?**
The validation tool will identify that the code does not follow the three-character alphabetic standard.

**Do I need to host this myself?**
No, Vinkius hosts and manages the MCP so it is ready to run the moment you connect.

**How do I know which currency codes are valid?**
You can use the `get_supported_currencies` tool to retrieve a full list of all valid three-letter currency identifiers recognized by the system.

**Can I verify if a specific code is correct?**
Yes, the `validate_currency_code` tool allows you to check if a string follows the standard three-letter alphabetic format.

**How is the conversion calculated?**
The `convert_currency` tool calculates the result by multiplying the base amount by the provided exchange rate.
