Implementation Reference
- src/index.ts:454-465 (registration)Registers the MCP tool 'get_label' with input schema (id: string) and inline handler. The handler uses the shared 'handleTool' utility to authenticate, create a Gmail client, and call gmail.users.labels.get to retrieve the label by ID, then formats the response.
server.tool("get_label", "Get a specific label by ID", { id: z.string().describe("The ID of the label to retrieve") }, async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.labels.get({ userId: 'me', id: params.id }) return formatResponse(data) }) } ) - src/index.ts:459-464 (handler)The inline handler function for the 'get_label' tool, which delegates to 'handleTool' for auth and API execution.
async (params) => { return handleTool(config, async (gmail: gmail_v1.Gmail) => { const { data } = await gmail.users.labels.get({ userId: 'me', id: params.id }) return formatResponse(data) }) } - src/index.ts:456-458 (schema)Input schema for 'get_label' tool using Zod: requires 'id' as string.
{ id: z.string().describe("The ID of the label to retrieve") }, - src/index.ts:50-66 (helper)Shared helper 'handleTool' used by 'get_label' and other tools to manage OAuth2 authentication, validate credentials, instantiate Gmail client, execute the provided API callback, 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:48-48 (helper)Utility to format API responses for MCP tools, used by 'get_label' handler.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
