Implementation Reference

• src/tools/staticData.js:17-26 (handler)

  Main handler function that executes the get_values tool logic. Maps CANONICAL_VALUES to labeled tokens and returns them with usage instructions.

  export function handleGetValues() {
    return {
      values: CANONICAL_VALUES.map(v => ({
        token: v,
        label: VALUE_LABELS[v] || v
      })),
      total: CANONICAL_VALUES.length,
      usage: 'Pass the "token" values in the "values" array when calling search_products or search_brands.'
    };
  }

• src/tools/staticData.js:8-15 (schema)

  Tool schema definition (name, description, inputSchema) for get_values. Input schema accepts an empty object as this tool requires no parameters.

  export const getValuesTool = {
    name: 'get_values',
    description: 'List all supported ethical/ownership values that can be used to filter products and brands. Returns canonical value tokens with display labels.',
    inputSchema: {
      type: 'object',
      properties: {}
    }
  };

• src/index.js:59-68 (registration)

  Tool registration in the MCP server. getValuesTool is added to the tools array returned by ListToolsRequestSchema handler.

  server.setRequestHandler(ListToolsRequestSchema, async () => ({
    tools: [
      searchProductsTool,
      searchBrandsTool,
      refineSearchTool,
      getValuesTool,
      getCategoriesTool,
      getCountriesTool
    ]
  }));

• src/index.js:90-92 (registration)

  Tool handler registration in the CallToolRequestSchema switch statement. Dispatches 'get_values' calls to handleGetValues().

  case 'get_values':
    result = handleGetValues();
    break;

• src/types.js:6-49 (helper)

  Data constants and label mappings used by the get_values handler. CANONICAL_VALUES defines the valid tokens and VALUE_LABELS provides human-readable display labels.

  export const CANONICAL_VALUES = [
    'women-owned', 'black-owned', 'indigenous-owned', 'latino-owned', 'aapi-owned',
    'veteran-owned', 'family-owned', 'lgbtq-owned', 'minority-owned',
    'b-corp', 'organic', 'sustainable', 'vegan', 'non-gmo', 'fair-trade', 'social-impact',
    'fragrance-free', 'plastic-free', 'cruelty-free', 'non-toxic', 'gluten-free'
