Implementation Reference
- src/index.ts:990-995 (handler)The handler function for the 'list_delegates' tool. It invokes handleTool to authenticate and call the Gmail API's users.settings.delegates.list method, then formats the response.async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.delegates.list({ userId: 'me' }) return formatResponse(data) }) }
- src/index.ts:987-996 (registration)Registration of the 'list_delegates' MCP tool using server.tool(), including empty input schema (no parameters required).server.tool("list_delegates", "Lists the delegates for the specified account", {}, async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.delegates.list({ userId: 'me' }) return formatResponse(data) }) } )
- src/index.ts:50-66 (helper)Shared helper function used by list_delegates (and other tools) to handle OAuth2 authentication, Gmail 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:48-48 (helper)Helper function to format API responses into MCP-compatible content structure, used by list_delegates.const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
