• src/rollbar.ts:357-373 (handler)

  Handler for 'rollbar_get_item' tool: validates project token, extracts item ID from arguments, fetches item data from Rollbar API endpoint '/item/{id}', and returns JSON response.

  case "rollbar_get_item": {
    // Project Token is required
    if (!projectClient) {
      throw new Error("ROLLBAR_PROJECT_TOKEN is not set, cannot use this API");
    }
  
    const { id } = args as { id: number };
    const response = await projectClient.get<ItemResponse>(`/item/${id}`);
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(response.data, null, 2),
        },
      ],
    };
  }

• src/rollbar.ts:141-151 (schema)

  Schema definition for 'rollbar_get_item' tool, specifying input requirements: object with required 'id' property of type number.

  const GET_ITEM_TOOL: Tool = {
    name: "rollbar_get_item",
    description: "Get a specific item (error) from Rollbar using the internal item ID maintained by Rollbar's system.",
    inputSchema: {

      GET_ITEM_TOOL,
      GET_ITEM_BY_UUID_TOOL,
      GET_ITEM_BY_COUNTER_TOOL,
