Implementation Reference
- src/index.ts:1248-1253 (handler)The handler function that executes the list_smime_info tool logic, calling the Gmail API to list S/MIME configurations for the specified send-as email address.async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.sendAs.smimeInfo.list({ userId: 'me', sendAsEmail: params.sendAsEmail }) return formatResponse(data) }) }
- src/index.ts:1245-1247 (schema)The Zod input schema defining the parameters for the list_smime_info tool, requiring a sendAsEmail string.{ sendAsEmail: z.string().describe("The email address that appears in the 'From:' header") },
- src/index.ts:1243-1254 (registration)The registration of the list_smime_info tool on the MCP server, including name, description, schema, and handler reference.server.tool("list_smime_info", "Lists S/MIME configs for the specified send-as alias", { sendAsEmail: z.string().describe("The email address that appears in the 'From:' header") }, async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.sendAs.smimeInfo.list({ userId: 'me', sendAsEmail: params.sendAsEmail }) return formatResponse(data) }) } )
- src/index.ts:49-65 (helper)Shared helper function used by list_smime_info (and other tools) 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 function used by list_smime_info (and other tools) to format the API response into MCP content structure.const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
