• src/index.ts:237-273 (handler)

  The "upload" tool handler. It resolves the item/publisher IDs, reads the ZIP file, and performs a POST request to the Google Chrome Web Store upload API.

  server.tool(
    "upload",
    "Upload a ZIP file to update an existing Chrome Web Store item draft. Note: Creating new items via API is not supported in v2 — use the Developer Dashboard to create new items.",
    {
      zipPath: z.string().describe("Absolute path to the ZIP file to upload"),
      itemId: z
        .string()
        .optional()
        .describe("Extension item ID (defaults to CWS_ITEM_ID env var)"),
      publisherId: z
        .string()
        .optional()
        .describe("Publisher ID (defaults to CWS_PUBLISHER_ID env var or 'me')"),
    },
    async ({ zipPath, itemId, publisherId }) => {
      try {
        const id = resolveItemId(itemId);
        const pub = resolvePublisherId(publisherId);
        const zipData = readFileSync(zipPath);
  
        const url = `${UPLOAD_BASE}/publishers/${pub}/items/${id}:upload`;
  
        const result = await apiCall(url, {
          method: "POST",
          headers: { "Content-Type": "application/zip" },
          body: zipData,
        });
  
        return formatResponse(result);
      } catch (e: any) {
        return {
          content: [{ type: "text" as const, text: `Error: ${e.message}` }],
          isError: true,
        };
      }
    },
  );
