- src/index.ts:1168-1185 (registration)Registers the 'update_send_as' MCP tool, including schema definition and inline handler function that updates a Gmail send-as alias using the Gmail API.server.tool("update_send_as", "Updates a send-as alias", { sendAsEmail: z.string().describe("The send-as alias to be updated"), displayName: z.string().optional().describe("A name that appears in the 'From:' header"), replyToAddress: z.string().optional().describe("An optional email address that is included in a 'Reply-To:' header"), signature: z.string().optional().describe("An optional HTML signature"), isPrimary: z.boolean().optional().describe("Whether this address is the primary address"), treatAsAlias: z.boolean().optional().describe("Whether Gmail should treat this address as an alias") }, async (params) => { const { sendAsEmail, ...updateData } = params return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.sendAs.update({ userId: 'me', sendAsEmail, requestBody: updateData }) return formatResponse(data) }) } )
- src/index.ts:1178-1184 (handler)The handler function for 'update_send_as' tool. Destructures parameters, uses shared handleTool to authenticate and call Gmail API's users.settings.sendAs.update method.async (params) => { const { sendAsEmail, ...updateData } = params return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.sendAs.update({ userId: 'me', sendAsEmail, requestBody: updateData }) return formatResponse(data) }) }
- src/index.ts:1171-1177 (schema)Zod schema defining input parameters for the 'update_send_as' tool.sendAsEmail: z.string().describe("The send-as alias to be updated"), displayName: z.string().optional().describe("A name that appears in the 'From:' header"), replyToAddress: z.string().optional().describe("An optional email address that is included in a 'Reply-To:' header"), signature: z.string().optional().describe("An optional HTML signature"), isPrimary: z.boolean().optional().describe("Whether this address is the primary address"), treatAsAlias: z.boolean().optional().describe("Whether Gmail should treat this address as an alias") },
- src/index.ts:49-65 (helper)Shared helper function used by 'update_send_as' and other tools 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}` } }
- src/index.ts:47-47 (helper)Shared helper to format API responses as MCP content.const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
