      responseBodyPlainText: z.string().describe("Response body in plain text format"),
      restrictToContacts: z.boolean().optional().describe("Whether responses are only sent to contacts"),
      restrictToDomain: z.boolean().optional().describe("Whether responses are only sent to users in the same domain"),
      startTime: z.string().optional().describe("Start time for sending auto-replies (epoch ms)"),
      endTime: z.string().optional().describe("End time for sending auto-replies (epoch ms)")
    },
    async (params) => {
      return handleTool(config, async (gmail: gmail_v1.Gmail) => {
        const { data } = await gmail.users.settings.updateVacation({ userId: 'me', requestBody: params })
        return formatResponse(data)
      })
    }
  )

      return formatResponse(data)
    })

• src/index.ts:931-938 (schema)

• src/index.ts:50-66 (helper)

  Shared helper function used by 'update_vacation' handler (and others) to handle OAuth2 authentication, client creation, and API call execution.

  const handleTool = async (queryConfig: Record<string, any> | undefined, apiCall: (gmail: gmail_v1.Gmail) => Promise<any>) => {
    try {
      const oauth2Client = queryConfig ? createOAuth2Client(queryConfig) : defaultOAuth2Client
      if (!oauth2Client) throw new Error('OAuth2 client could not be created, please check your credentials')
  
      const credentialsAreValid = await validateCredentials(oauth2Client)
      if (!credentialsAreValid) throw new Error('OAuth2 credentials are invalid, please re-authenticate')
  
      const gmailClient = queryConfig ? google.gmail({ version: 'v1', auth: oauth2Client }) : defaultGmailClient
      if (!gmailClient) throw new Error('Gmail client could not be created, please check your credentials')
  
      const result = await apiCall(gmailClient)
      return result
    } catch (error: any) {
      return `Tool execution failed: ${error.message}`
    }
  }
