# Language Detector Engine MCP for AI Agents AI Agent Connect

> Language Detector Engine identifies the language of any text using exact n-gram analysis. It supports over 400 languages and provides deterministic results, making it perfect for situations where your AI client might guess incorrectly on short or mixed strings. It returns standard ISO 639-3 codes and handles ambiguous text properly, returning 'undefined' instead of hallucinating.

## Description

The Language Detector Engine gives your AI client a reliable way to identify languages without the guesswork. When you're processing thousands of customer support tickets or scraping multi-lingual data, relying on a model's 'best guess' leads to messy routing and wasted time. This Connector uses a deterministic math approach to analyze character frequencies, ensuring you get consistent results every time. It handles everything from common languages like English and Spanish to obscure ones like Zulu or Esperanto. If the text is too short or confusing to identify with certainty, it tells you it's undefined instead of making something up. You can even restrict the search to a specific list of languages to keep your data clean. Finding this in the Vinkius catalog makes it easy to plug into your existing workflow. It's built for high-volume environments where accuracy is non-negotiable and you need to know exactly what language a user is speaking before you take action.

## Tools

### detect_language
Identify the language of a text string and get the ISO 639-3 code. The Language Detector Engine works across 400+ languages using deterministic math to ensure consistent results.

## Prompt Examples

**Prompt:** 
```
Detect the language of this support ticket: 'Não consigo acessar minha conta desde ontem'.
```

**Response:** 
```
### Detection Result

*   **Detected Language:** `por` (Portuguese)
*   **Confidence:** 100%
*   **Status:** Confirmed

This ticket has been correctly identified for the Portuguese support queue.
```

**Prompt:** 
```
We only support English and Spanish. Detect the language of 'Hola como estas' using the whitelist.
```

**Response:** 
```
### Detection Result

*   **Detected Language:** `spa` (Spanish)
*   **Allowed List:** `['eng', 'spa']`
*   **Status:** Valid

The input matches an allowed language in your supported list.
```

**Prompt:** 
```
Get the top 3 language probabilities for this ambiguous name: 'Alejandro'.
```

**Response:** 
```
| Rank | Language Code | Language Name | Probability |
| :--- | :--- | :--- | :--- |
| 1 | `spa` | Spanish | 100% |
| 2 | `glg` | Galician | 82% |
| 3 | `cat` | Catalan | 64%

Note: This name is highly ambiguous across multiple Romance languages.
```

## Capabilities

### Identify languages in text
The Language Detector Engine identifies the language of any text string to provide standard ISO 639-3 codes.

### Filter by specific languages
The Language Detector Engine allows you to restrict detection to a specific whitelist of supported languages.

### Get confidence scores
The Language Detector Engine provides exact probability scores for multiple language matches when requested.

### Handle ambiguous text
The Language Detector Engine returns an undefined status for text that is too short or confusing to identify.

### Process mixed content
The Language Detector Engine uses character frequency math to analyze strings with multiple languages.

## Use Cases

### Support Ticket Routing
A customer sends a message in Portuguese. An agent uses the Language Detector Engine to route it to the correct regional queue instantly.

### Content Moderation
A system scans posts in 50 different countries. It uses the Connector to group them by language for specific moderation rules.

### Data Cleaning
A dataset has mixed languages. You use the detection tool to flag rows that need manual review or translation.

### User Onboarding
A sign-up form captures input from global users. The agent identifies the language to set the correct UI preference automatically.

## Benefits

- Stop routing errors by using the Language Detector Engine to ensure support tickets go to the right team every time.
- Get high language coverage with the Language Detector Engine's support for over 400 different languages and dialects.
- Enforce strict evaluation using the Language Detector Engine's whitelist to limit detection to only the languages your business supports.
- Improve data integrity with the Language Detector Engine's undefined status for ambiguous text instead of a hallucinated guess.
- Track confidence scores with the Language Detector Engine's all flag to see the exact probability for multiple potential matches.

## How It Works

The bottom line is the Language Detector Engine provides deterministic results for multi-lingual data.

1. Connect your AI client to the Language Detector Engine via the Vinkius marketplace.
2. Send any text string to the detection tool along with any optional language filters.
3. Receive the primary language code and a list of confidence scores for the top matches.

## Frequently Asked Questions

**How does the Language Detector Engine handle short text?**
The Language Detector Engine uses n-gram analysis to identify languages even in short strings. If the text is too short to be certain, it returns an undefined status to prevent incorrect guesses.

**Can the Language Detector Engine identify rare languages?**
Yes, it supports over 400 languages. This includes common global languages as well as less common regional dialects and languages like Zulu or Esperanto.

**What happens if the Language Detector Engine can't find a match?**
If the input is too ambiguous or doesn't match any known patterns, the Language Detector Engine returns 'undefined'. This ensures your AI agent doesn't hallucinate a language.

**Does the Language Detector Engine support Spanish and Portuguese?**
Yes, the Language Detector Engine identifies both Spanish and Portuguese accurately, providing standard ISO 639-3 codes for both.

**How accurate is the Language Detector Engine for mixed text?**
The Language Detector Engine analyzes character frequencies to handle mixed content. It can identify the primary language even when multiple languages appear in the same string.

**Can I limit the Language Detector Engine to specific languages?**
Yes, you can use a whitelist to force the Language Detector Engine to only look for specific codes. This is ideal for businesses that only support a few specific regions.

**How does the Language Detector Engine help with support tickets?**
It identifies the language of incoming tickets instantly. This allows your AI agent to route messages to the correct regional team without manual intervention.

**Why is this better than asking Claude to detect the language?**
LLMs often hallucinate languages for short strings or names. They also struggle to provide standardized ISO codes reliably. This engine uses mathematical N-gram analysis (the same technique behind Google Search language detection) to deterministically map text to one of 400+ ISO 639-3 codes.

**What does it mean if it returns 'und'?**
'und' stands for Undefined. It means the text is too short, mostly numbers, or too ambiguous to confidently map to a single language. This is a feature — it prevents your routing logic from making false assumptions.

**Can I force it to choose between specific languages?**
Yes. Pass an array of ISO 639-3 codes to the 'only' parameter (e.g., ['eng', 'por', 'spa']). The engine will only calculate probabilities within that subset.
