xcstrings-mcp

What it does

Provides a structured bridge between AI assistants and Xcode String Catalog (.xcstrings) files. It prevents context-window bloat by fetching keys in batches and ensures atomic writes that preserve Xcode's strict JSON formatting.

Tools

• parse_xcstrings: Caches and indexes localization files.
• get_untranslated: Retrieves untranslated strings in manageable batches.
• submit_translations: Validates and writes translations atomically to disk.
• validate_translations: Performs file-wide validation of format specifiers and plurals.
• export_xliff: Exports catalogs to XLIFF 1.2 for professional translation services.
• import_strings: Migrates legacy .strings and .stringsdict files to the new catalog format.
