Printify MCP Server

Implementation Reference

• src/services/printify-shops.ts:10-52 (handler)

  Core handler logic for get_printify_status: the getPrintifyStatus function that validates the client, fetches shops and current shop, and formats the status response.

  export async function getPrintifyStatus(printifyClient: PrintifyAPI) {
    try {
      // Validate client is initialized
      if (!printifyClient) {
        throw new Error('Printify API client is not initialized. The PRINTIFY_API_KEY environment variable may not be set.');
      }
      
      // Get shops and current shop
      const shops = await printifyClient.getShops();
      const currentShop = printifyClient.getCurrentShop();
      
      return {
        success: true,
        shops,
        currentShop,
        response: {
          content: [{
            type: "text",
            text: `Printify API Status:\n\n` +
                  `Connected: Yes\n` +
                  `Available Shops: ${shops.length}\n` +
                  `Current Shop: ${currentShop ? `${currentShop.title} (ID: ${currentShop.id})` : 'None'}`
          }]
        }
      };
    } catch (error: any) {
      console.error('Error getting Printify status:', error);
      
      return {
        success: false,
        error,
        errorResponse: formatErrorResponse(
          error,
          'Get Printify Status',
          {},
          [
            'Check that your Printify API key is valid',
            'Ensure your Printify account is properly connected'
          ]
        )
      };
    }
  }

• src/index.ts:87-115 (registration)

  Registration of the 'get_printify_status' tool via server.tool(). The inline handler checks client initialization and delegates to the getPrintifyStatus service function, returning formatted response.

  server.tool(
    "get_printify_status",
    {},
    async ({}): Promise<{ content: any[], isError?: boolean }> => {
      // Import the printify shops service
      const { getPrintifyStatus } = await import('./services/printify-shops.js');
  
      // Check if client is initialized
      if (!printifyClient) {
        return {
          content: [{
            type: "text",
            text: "Printify API client is not initialized. The PRINTIFY_API_KEY environment variable may not be set."
          }],
          isError: true
        };
      }
  
      // Call the service
      const result = await getPrintifyStatus(printifyClient);
  
      // Return the result
      if (result.success) {
        return result.response as { content: any[], isError?: boolean };
      } else {
        return result.errorResponse as { content: any[], isError: boolean };
      }
    }
  );
