- Real-world use case 01
Fixing broken pluralization
A developer pushes a change that breaks pluralization; they ask their agent to check the new string using validate_category_logic.
- Real-world use case 02
Mapping required data keys
An engineer needs to know which keys to add to a JSON file; they use extract_template_variables to get the list.
- Real-world use case 03
Auditing large translation batches
A localization lead is worried about broken quotes in a large batch of strings; they run validate_structural_braces on the set.

Validate category logic
Checks that your plural and select blocks use valid categories like 'one' or 'other'. It ensures you never miss a required fallback category.
- 02 Capability
Extract template variables
Scans your message strings to find every unique variable name used. This gives you an instant list of all necessary interpolation parameters.
- 03 Capability
Validate structural braces
Inspects the string for unmatched curly braces or broken quote escaping. It prevents structural errors from corrupting your translation engine.

Before you connect
Questions about ICU MessageFormat Validator.
The practical details behind the request, access and result.
How can I use ICU MessageFormat Validator Alternative to check my translations?
You provide your ICU strings to your AI client, and it will analyze them for syntax errors or missing categories.
Does ICU MessageFormat Validator Alternative catch unmatched braces?
Yes, it specifically looks for any opening or closing curly brackets that do not have a matching pair.
Can I find all variables in a message using ICU MessageFormat Validator Alternative?
Absolutely. You can ask your agent to list every dynamic parameter used within a specific template string.
Will ICU MessageFormat Validator Alternative help with pluralization errors?
It checks that all categories like 'one', 'few', and 'many' are correctly defined and that the 'other' category is present.
Is ICU MessageFormat Validator Alternative compatible with Claude or Cursor?
Yes, it works with any MCP-compatible client including Claude, Cursor, and Windsurf.
How does the validator handle single quotes?
The validate_structural_braces capability implements a state machine to track escaping. It recognizes that two consecutive single quotes (double-single-quote) represent a literal single quote, preventing the parser from incorrectly terminating an escaped sequence.
What happens if I use an invalid category in a plural block?
If you include an unsupported keyword like 'none' or 'all', the validate_category_logic capability will flag a syntax error, identifying the exact character offset where the invalid category was detected.
Can I use this to find all variables in my translation files?
Yes, by using the extract_template_variables capability, you can provide any ICU string and receive a complete list of all unique variable names found within the template, such as 'userName' or 'itemCount'.
