async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.labels.delete({ userId: 'me', id: params.id }) return formatResponse(data) }) } - src/index.ts:443-445 (schema)Input schema using Zod for the 'delete_label' tool, requiring a string 'id' parameter.
{ id: z.string().describe("The ID of the label to delete") }, - src/index.ts:441-452 (registration)Registration of the 'delete_label' MCP tool on the server, specifying name, description, input schema, and handler function.
