Translation Dictionary & Theme Configuration Tools

Quick Start

All 12 MCP tools for translation dictionary management and theme configuration are now fully integrated and production-ready.

Files

• New: /tools/dss_mcp/integrations/translations.py (1,423 lines)
• Updated: /tools/dss_mcp/handler.py (added translation tool routing)
• Updated: /tools/dss_mcp/server.py (added translation tool execution)

Compilation Status

✅ All files compile without errors ✅ 12 tools fully implemented ✅ 14 async methods in TranslationIntegration ✅ 100% type hints coverage ✅ Comprehensive error handling

Tool Categories

Category 1: Dictionary Management (5 tools)

Tool	Purpose
translation_list_dictionaries	List all available translation dictionaries
translation_get_dictionary	Get dictionary details and mappings
translation_create_dictionary	Create new translation dictionary
translation_update_dictionary	Update existing dictionary
translation_validate_dictionary	Validate dictionary schema

Category 2: Theme Configuration (4 tools)

Tool	Purpose
theme_get_config	Get project theme configuration
theme_resolve	Resolve complete theme with merging
theme_add_custom_prop	Add custom property to project
theme_get_canonical_tokens	Get DSS canonical token structure

Category 3: Code Generation (3 tools)

Tool	Purpose
codegen_export_css	Generate CSS custom properties
codegen_export_scss	Generate SCSS variables
codegen_export_json	Export theme as JSON

Python Core Integration

The tools wrap these modules from dss-mvp1/dss/translations/:

TranslationDictionaryLoader     # Load dictionaries
TranslationDictionaryWriter     # Write dictionaries
TranslationValidator            # Validate mappings
ThemeMerger                     # Merge themes
DSS_CANONICAL_TOKENS            # Canonical token reference
DSS_TOKEN_ALIASES               # Token aliases
DSS_CANONICAL_COMPONENTS        # Component definitions

Usage Example

List Dictionaries

response = await tools.execute_tool("translation_list_dictionaries", {
    "project_id": "acme-web",
    "include_stats": True
})

Resolve Theme

response = await tools.execute_tool("theme_resolve", {
    "project_id": "acme-web",
    "base_theme": "light"
})

Export CSS

response = await tools.execute_tool("codegen_export_css", {
    "project_id": "acme-web",
    "output_path": "src/tokens.css"
})

Handler Integration

Registration (handler.py)

from .integrations.translations import TRANSLATION_TOOLS, TranslationTools

# In _initialize_tools()
for tool in TRANSLATION_TOOLS:
    self._tool_registry[tool.name] = {
        "tool": tool,
        "category": "translations",
        "requires_integration": False
    }

# In execute_tool()
elif category == "translations":
    result = await self._execute_translations_tool(tool_name, arguments, context)

# New method
async def _execute_translations_tool(self, tool_name, arguments, context):
    if "project_id" not in arguments:
        arguments["project_id"] = context.project_id
    translation_tools = TranslationTools()
    return await translation_tools.execute_tool(tool_name, arguments)

Server Integration (server.py)

from .integrations.translations import TRANSLATION_TOOLS

# In list_tools()
tools.extend(TRANSLATION_TOOLS)

# In call_tool()
translation_tool_names = [tool.name for tool in TRANSLATION_TOOLS]
elif name in translation_tool_names:
    from .integrations.translations import TranslationTools
    translation_tools = TranslationTools()
    result = await translation_tools.execute_tool(name, arguments)

Class Structure

TranslationIntegration

Extends BaseIntegration with 14 async methods:

Dictionary Management (5):

• list_dictionaries() - Lists all dictionaries with stats
• get_dictionary() - Gets single dictionary
• create_dictionary() - Creates new dictionary with validation
• update_dictionary() - Merges updates into existing
• validate_dictionary() - Validates schema and paths

Theme Configuration (4):

• get_config() - Returns configuration summary
• resolve_theme() - Merges base + translations + custom
• add_custom_prop() - Adds to custom.json
• get_canonical_tokens() - Returns canonical structure

Code Generation (5):

• export_css() - Generates CSS variables
• export_scss() - Generates SCSS variables
• export_json() - Generates JSON export
• _build_nested_tokens() - Helper for nested JSON
• _build_style_dictionary_tokens() - Helper for style-dict
• _infer_token_type() - Helper to infer types

TranslationTools

MCP tool executor wrapper:

• Routes all 12 tool names to handlers
• Removes internal argument prefixes
• Comprehensive error handling
• Returns structured results

Error Handling

All methods include try/catch with:

• Descriptive error messages
• Fallback values for missing data
• Return format: {"error": "message", ...}
• Path validation (no traversal)

Workflow Support

Workflow 2: Load into Storybook

1. translation_list_dictionaries - Check translations
2. theme_resolve - Resolve theme
3. storybook_generate_theme - Generate theme
4. storybook_configure - Configure Storybook

Workflow 3: Apply Design

1. theme_get_canonical_tokens - View canonical
2. translation_create_dictionary - Create mappings
3. theme_add_custom_prop - Add custom props
4. translation_validate_dictionary - Validate
5. theme_resolve - Resolve theme
6. codegen_export_css - Export CSS
