Ensure your marketing copy remains professional and error-free with the Personalization Token Validator. This MCP server provides a suite of specialized tools to audit dynamic merge fields (e.g., {{first_name}}) within templates. Use check_syntax_integrity to find malformed or orphaned braces, verify_fallback_availability to ensure every token has a defined default value, and evaluate_density_threshold to prevent 'over-personalization' that makes text feel robotic. Additionally, audit_grammatical_flow flags potential 'a/an' mismatches caused by dynamic insertions. By integrating this tool into your workflow via Vinkius Edge, you can maintain high linguistic standards and prevent broken templates from reaching your customers.

Check if this template has any broken braces: 'Hello {{first_name}}, welcome to {{company}}!'

The syntax is valid. All braces are properly matched and no malformed tokens were detected.

Is the token density too high in this text: 'Hi {{name}}, welcome to {{city}}! We love {{brand}}!'

The current density is 100 tokens per 100 words, which exceeds the threshold.

Check for grammar risks in: 'An {{user_name}} is joining us.'

A risk was detected: the article 'An' precedes a token where the fallback value might start with a consonant.

It identifies malformed tokens or broken braces within your template string, ensuring all `{{tokens}}` are properly closed. Tools available: `validate_token`.
