Implementation Reference
- src/index.ts:943-960 (registration)Complete MCP tool registration for 'update_vacation', defining the tool name, description, Zod input schema for vacation responder parameters, and handler function that delegates to handleTool for authenticated Gmail API call to updateVacation.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) }) } )
- src/index.ts:50-80 (handler)Core handler utility used by update_vacation (and all tools) to manage OAuth2 authentication, validate credentials, create Gmail client, execute the API call, and handle authentication-specific errors gracefully.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}` }); } }
- src/index.ts:48-48 (helper)Utility function used by all tools, including update_vacation, to format API responses as MCP-compatible content blocks with JSON-stringified text.const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
