Implementation Reference
- src/index.ts:820-829 (registration)Registration of the 'get_language' MCP tool. It has no input parameters (empty schema), and the handler fetches the user's Gmail language settings using the Gmail API and formats the response using shared helpers.
server.tool("get_language", "Gets language settings", {}, async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.getLanguage({ userId: 'me' }) return formatResponse(data) }) } ) - src/index.ts:823-828 (handler)The inline handler function for the 'get_language' tool. It uses the shared 'handleTool' helper to execute the Gmail API call to retrieve language settings.
async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.getLanguage({ userId: 'me' }) return formatResponse(data) }) } - src/index.ts:49-65 (helper)Shared helper function 'handleTool' used by 'get_language' and other tools to manage OAuth2 authentication, create Gmail client, execute the API call, and handle errors.
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 'formatResponse' used by 'get_language' and other tools to format API responses into MCP content format.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
