Implementation Reference

• src/index.ts:407-445 (handler)

  The handler implementation for the "deploy-percentage" tool which makes a POST request to the Chrome Web Store API to update the deploy percentage.

  server.tool(
    "deploy-percentage",
    "Set the published deploy percentage for staged rollout on Chrome Web Store. The new percentage must be higher than the current target. Only available for items with 10,000+ seven-day active users.",
    {
      percentage: z
        .number()
        .min(0)
        .max(100)
        .describe("Deploy percentage (0-100). Must be larger than the current target percentage."),
      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 ({ percentage, itemId, publisherId }) => {
      try {
        const id = resolveItemId(itemId);
        const pub = resolvePublisherId(publisherId);
  
        const url = `${API_BASE}/v2/publishers/${pub}/items/${id}:setPublishedDeployPercentage`;
        const result = await apiCall(url, {
          method: "POST",
          headers: { "Content-Type": "application/json" },
          body: JSON.stringify({ deployPercentage: percentage }),
        });
