Printify MCP Server

Implementation Reference

• src/services/printify-products.ts:313-367 (handler)

  Core handler function for the publish_product MCP tool. Validates the current shop selection, calls the Printify API client's publishProduct method, handles errors, and formats structured success/error responses.

  export async function publishProduct(
    printifyClient: PrintifyAPI,
    productId: string,
    publishDetails?: {
      title?: boolean;
      description?: boolean;
      images?: boolean;
      variants?: boolean;
      tags?: boolean;
    }
  ) {
    try {
      // Validate shop is selected
      const currentShop = printifyClient.getCurrentShop();
      if (!currentShop) {
        throw new Error('No shop is currently selected. Use the list-shops and switch-shop tools to select a shop.');
      }
  
      // Publish product
      const result = await printifyClient.publishProduct(productId, publishDetails);
  
      return {
        success: true,
        result,
        response: formatSuccessResponse(
          'Product Published Successfully',
          {
            ProductId: productId,
            Shop: currentShop
          }
        )
      };
    } catch (error: any) {
      console.error('Error publishing product:', error);
  
      return {
        success: false,
        error,
        errorResponse: formatErrorResponse(
          error,
          'Publish Product',
          {
            ProductId: productId,
            PublishDetails: publishDetails,
            Shop: printifyClient.getCurrentShop()
          },
          [
            'Check that the product ID is valid',
            'Ensure your Printify account is properly connected',
            'Make sure you have selected a shop'
          ]
        )
      };
    }
  }

• src/index.ts:385-422 (registration)

  MCP server.tool registration for 'publish_product' tool, including Zod input schema validation and thin wrapper handler that injects the global printifyClient and delegates to the core handler.

  server.tool(
    "publish_product",
    {
      productId: z.string().describe("Product ID"),
      publishDetails: z.object({
        title: z.boolean().optional().default(true).describe("Publish title"),
        description: z.boolean().optional().default(true).describe("Publish description"),
        images: z.boolean().optional().default(true).describe("Publish images"),
        variants: z.boolean().optional().default(true).describe("Publish variants"),
        tags: z.boolean().optional().default(true).describe("Publish tags")
      }).optional().describe("Publish details")
    },
    async ({ productId, publishDetails }): Promise<{ content: any[], isError?: boolean }> => {
      // Import the printify products service
      const { publishProduct } = await import('./services/printify-products.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 publishProduct(printifyClient, productId, publishDetails);
  
      // Return the result
      if (result.success) {
        return result.response as { content: any[], isError?: boolean };
      } else {
        return result.errorResponse as { content: any[], isError: boolean };
      }
    }
  );

• src/index.ts:387-396 (schema)

  Zod schema for input parameters of the publish_product tool: productId (string) and optional publishDetails object specifying which product fields to publish.

  {
    productId: z.string().describe("Product ID"),
    publishDetails: z.object({
      title: z.boolean().optional().default(true).describe("Publish title"),
      description: z.boolean().optional().default(true).describe("Publish description"),
      images: z.boolean().optional().default(true).describe("Publish images"),
      variants: z.boolean().optional().default(true).describe("Publish variants"),
      tags: z.boolean().optional().default(true).describe("Publish tags")
    }).optional().describe("Publish details")
  },

• src/printify-api.ts:390-402 (helper)

  PrintifyAPI class method that wraps the Printify SDK's products.publishOne call, with shop ID validation and enhanced error handling.

  async publishProduct(productId: string, publishData: any) {
    if (!this.shopId) {
      throw new Error('Shop ID is not set. Call setShopId() first.');
    }
  
    try {
      // Use the products.publishOne method with the product ID and publish data
      return await this.client.products.publishOne(productId, publishData);
    } catch (error) {
      console.error(`Error publishing product ${productId}:`, error);
      throw this.enhanceError(error, publishData);
    }
  }
