- src/index.ts:1235-1238 (schema)Zod input schema defining the required parameters sendAsEmail and id for the delete_smime_info tool.{ sendAsEmail: z.string().describe("The email address that appears in the 'From:' header"), id: z.string().describe("The immutable ID for the S/MIME config") },
- src/index.ts:1233-1245 (registration)Registration of the delete_smime_info tool using server.tool(), including description, input schema, and handler function.server.tool("delete_smime_info", "Deletes the specified S/MIME config for the specified send-as alias", { sendAsEmail: z.string().describe("The email address that appears in the 'From:' header"), id: z.string().describe("The immutable ID for the S/MIME config") }, async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.sendAs.smimeInfo.delete({ userId: 'me', sendAsEmail: params.sendAsEmail, id: params.id }) return formatResponse(data) }) } )
