Implementation Reference
- src/index.ts:440-445 (handler)The handler function for the 'get_label' tool. It uses handleTool to manage authentication and Gmail client creation, then calls the Gmail API to retrieve the specific label by its ID, and formats the response.
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:437-439 (schema)Input schema for the 'get_label' tool, defining a required string parameter 'id' for the label ID.
{ id: z.string().describe("The ID of the label to retrieve") }, - src/index.ts:435-446 (registration)Registration of the 'get_label' tool on the MCP server, specifying name, description, input schema, and handler function.
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:49-65 (helper)Shared helper function used by all Gmail tools, including get_label, to handle OAuth2 authentication, client creation, and error handling around API calls.
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 to format API responses into MCP-compatible content structure for tools like get_label.
const formatResponse = (response: any) => ({ content: [{ type: "text", text: JSON.stringify(response) }] })
