Implementation Reference

• src/index.ts:943-960 (registration)

  Tool registration for 'update_vacation' using server.tool(), defining the tool name, description, input schema parameters, and an async handler callback.

  server.tool("update_vacation",
    "Update vacation responder settings",
    {
      enableAutoReply: z.boolean().describe("Whether the vacation responder is enabled"),
      responseSubject: z.string().optional().describe("Optional subject line for the vacation responder auto-reply"),
      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)
      })
    }
  )

    responseBodyPlainText: z.string().describe("Response body in plain text format"),

• src/index.ts:954-960 (handler)

  Handler function for update_vacation. Calls gmail.users.settings.updateVacation() with the provided parameters and returns the response.

    async (params) => {
      return handleTool(config, async (gmail: gmail_v1.Gmail) => {
        const { data } = await gmail.users.settings.updateVacation({ userId: 'me', requestBody: params })
        return formatResponse(data)
      })
    }
  )

• src/index.ts:50-80 (helper)

  The handleTool helper function that wraps all tool handlers, providing OAuth2 validation and error handling.

  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) {
      // Check for specific authentication errors
      if (
        error.message?.includes("invalid_grant") ||
        error.message?.includes("refresh_token") ||
        error.message?.includes("invalid_client") ||
        error.message?.includes("unauthorized_client") ||
        error.code === 401 ||
        error.code === 403
      ) {
        return formatResponse({
          error: `Authentication failed: ${error.message}. Please re-authenticate by running: npx @shinzolabs/gmail-mcp auth`,
        });
      }
  
      return formatResponse({ error: `Tool execution failed: ${error.message}` });
    }
  }
