Implementation Reference
- src/index.ts:831-840 (registration)Registration of the 'get_pop' MCP tool, including description, empty input schema (no parameters), and inline handler function.
server.tool("get_pop", "Gets POP settings", {}, async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.getPop({ userId: 'me' }) return formatResponse(data) }) } ) - src/index.ts:834-839 (handler)The handler function for the 'get_pop' tool. It invokes the shared handleTool helper to perform OAuth2 authentication/validation and calls the Gmail API's users.settings.getPop method for the current user ('me'), then formats the response.
async () => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.settings.getPop({ userId: 'me' }) return formatResponse(data) }) } - src/index.ts:833-833 (schema)Input schema for 'get_pop' tool: empty object, indicating no parameters are required.
{}, - src/index.ts:49-65 (helper)Shared helper function 'handleTool' used by 'get_pop' (and other tools) to handle OAuth2 client creation, credential validation, Gmail client instantiation, API call execution, and 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:47-47 (helper)Helper function 'formatResponse' used to standardize tool responses into MCP content format with JSON-stringified data.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
