Implementation Reference
- src/index.ts:853-862 (registration)Registration of the 'get_language' MCP tool, including empty input schema and inline asynchronous handler function that retrieves Gmail language settings via the Gmail API.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:856-862 (handler)Handler function for 'get_language' tool: calls handleTool with Gmail client to execute gmail.users.settings.getLanguage API and formats response.async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.getLanguage({ userId: 'me' }) return formatResponse(data) }) } )
- src/index.ts:50-80 (helper)Shared helper function handleTool used by get_language (and other tools) to handle OAuth2 authentication, Gmail client creation, API call execution, and error handling including auth-specific responses.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:48-49 (helper)Shared helper formatResponse used by get_language (and other tools) to format API results into MCP content structure.const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
