Choose Xcomet MCP Server if your workspace requires Translation Services integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose MachineTranslation.com MCP when:
You need dedicated capabilities in the Translation Services domain.
You prefer remote streaming HTTP/SSE transport architecture.
Your security boundary fits: OAuth 2.0 (Paid Service).
Primary tools included: SMART translation across 22 AI models, Consensus-based translation output, Supported language code discovery.
Brings SMART consensus translation into any MCP client. Runs your text through 22 leading AI translation models at once and returns only the output the models agree on, so you get a confidence-backed result instead of a single engine's guess. Exposes two tools: smart_translate (text, source language, target language) and list_languages (all supported language codes). Hosted remote server at https://www.machinetranslation.com/mcp over streamable HTTP — no install, no API key, just connect the URL and sign in. Built for translators, localization and content teams, marketers, and developers.
Translation quality evaluation using xCOMET models. Provides quality scoring (0-1), error detection with severity levels (minor/major/critical), and optimized batch processing with 25x speedup.

Evaluate the quality of a translation using xCOMET model.
This tool analyzes a source text and its translation, providing:
- A quality score between 0 and 1 (higher is better)
- Detected error spans with severity levels (minor/major/critical)
- A human-readable quality summary
Args:
- source (string): Original source text to translate from
- translation (string): Translated text to evaluate
- reference (string, optional): Reference translation for comparison
- source_lang (string, optional): Source language code (ISO 639-1)
- target_lang (string, optional): Target language code (ISO 639-1)
- response_format ('json' | 'markdown'): Output format (default: 'json')
- use_gpu (boolean, optional): Use GPU for inference if available (default: false)
Returns:
For JSON format:
{
"score": number, // Quality score 0-1
"errors": [ // Detected errors
{
"text": string,
"start": number,
"end": number,
"severity": "minor" | "major" | "critical"
}
],
"summary": string // Human-readable summary
}
Examples:
- Evaluate EN→JA translation quality
- Check if MT output needs post-editing
- Compare translation against reference
xcomet_detect_errors
Detect and categorize errors in a translation.
This tool focuses on error detection, providing detailed information about
translation errors with their severity levels and positions.
Args:
- source (string): Original source text
- translation (string): Translated text to analyze
- reference (string, optional): Reference translation
- min_severity ('minor' | 'major' | 'critical'): Minimum severity to report (default: 'minor')
- response_format ('json' | 'markdown'): Output format (default: 'json')
- use_gpu (boolean, optional): Use GPU for inference if available (default: false)
Returns:
{
"total_errors": number,
"errors_by_severity": {
"minor": number,
"major": number,
"critical": number
},
"errors": [
{
"text": string,
"start": number,
"end": number,
"severity": "minor" | "major" | "critical"
}
]
}
Examples:
- Find critical errors before publication
- Identify areas needing post-editing
- Quality gate for MT output
xcomet_batch_evaluate
Evaluate multiple translation pairs in a batch.
This tool processes multiple source-translation pairs and provides
aggregate statistics along with individual results.
Args:
- pairs (array): Array of translation pairs, each with:
- source (string): Original source text
- translation (string): Translated text
- reference (string, optional): Reference translation
- source_lang (string, optional): Source language code
- target_lang (string, optional): Target language code
- response_format ('json' | 'markdown'): Output format (default: 'json')
- use_gpu (boolean, optional): Use GPU for inference if available (default: false)
- batch_size (number, optional): Inference batch size, 1-64 (default: 8).
Larger = faster but uses more memory.
Returns:
{
"average_score": number,
"total_pairs": number,
"results": [
{
"index": number,
"score": number,
"error_count": number,
"has_critical_errors": boolean
}
],
"summary": string
}
Examples:
- Evaluate entire translated document
- Compare MT system quality across test set
- Identify segments needing attention
