Implementation Reference

• src/index.ts:1057-1068 (registration)

  Registration of the 'delete_forwarding_address' tool, including description, input schema (forwardingEmail), and inline handler function that executes the Gmail API deletion via handleTool.

  server.tool("delete_forwarding_address",
    "Deletes the specified forwarding address",
    {
      forwardingEmail: z.string().describe("The forwarding address to be deleted")
    },
    async (params) => {
      return handleTool(config, async (gmail: gmail_v1.Gmail) => {
        const { data } = await gmail.users.settings.forwardingAddresses.delete({ userId: 'me', forwardingEmail: params.forwardingEmail })
        return formatResponse(data)
      })
    }
  )

• src/index.ts:1062-1067 (handler)

  The handler function for the tool, which invokes the shared handleTool helper to perform OAuth-authorized deletion of the forwarding address using Gmail API.

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

• src/index.ts:1059-1061 (schema)

  Zod schema defining the input parameter 'forwardingEmail' as a required string.

  {
    forwardingEmail: z.string().describe("The forwarding address to be deleted")
  },

• src/index.ts:49-65 (helper)

  Shared helper function used by all Gmail tools to handle OAuth2 client creation, credential validation, Gmail client instantiation, and API call execution with 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) {
      return `Tool execution failed: ${error.message}`
    }
  }

• src/index.ts:47-47 (helper)
