Instructions

Implementation Reference

• src/index.ts:1200-1212 (registration)

  Registration of the 'delete_smime_info' MCP tool, including inline input schema using Zod and the handler function that invokes the Gmail API to delete the specified S/MIME configuration for a send-as alias.

  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)
      })
    }
  )

• src/index.ts:1206-1211 (handler)

  Handler function for 'delete_smime_info' tool that uses the shared handleTool utility to authenticate and call the Gmail API's users.settings.sendAs.smimeInfo.delete method.

  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)
    })
  }

• src/index.ts:1202-1205 (schema)

  Input schema for 'delete_smime_info' tool defined inline using Zod, requiring sendAsEmail and id parameters.

  {
    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:49-65 (helper)

  Shared helper function 'handleTool' used by all Gmail API tools, including 'delete_smime_info', to handle OAuth2 authentication, client creation, 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)

  Shared helper 'formatResponse' used to standardize tool responses as MCP content blocks with JSON stringified data.

  const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
