description	Implements Google Analytics (GA4) reporting, metadata exploration, and account management using generated clients and MCP tools. Use when doing ANYTHING that touches Google Analytics or GA4 in any way, load this skill.

Major Platform Resource: Google Analytics

Common: Interacting with Resources

Security: Never connect directly to APIs. Never use credentials in code. Always use generated clients or MCP tools.

Two ways to interact with resources:

1. MCP tools (direct, no code needed): Tools follow the pattern mcp__resources__<resourcetype>_<toolname>. Use mcp__resources__list_resources to discover available resources and their IDs.
2. Generated TypeScript clients (for app code): Call mcp__resource-tools__add-resource-client with a resourceId to generate a typed client. Clients are created in /clients/ (Next.js) or /src/clients/ (Vite).

CRITICAL: Do NOT guess client method names or signatures. The TypeScript clients in @major-tech/resource-client have strongly typed inputs and outputs. ALWAYS read the actual client source code in the generated /clients/ directory (or the package itself) to verify available methods and their exact signatures before writing any client code.

Framework note: Next.js = resource clients must be used in server-side code only (Server Components, Server Actions, API Routes). Vite = call directly from frontend.

Error handling: Always check result.ok before accessing result.result.

Invocation keys must be static strings — use descriptive literals like "fetch-page-views", never dynamic values like `${date}-report`.

MCP Tools

• mcp__resources__googleanalytics_run_report — Run a GA4 report with dimensions, metrics, and date ranges. Args: resourceId, dimensions, metrics, dateRanges, orderBys?, limit?, offset?
• mcp__resources__googleanalytics_get_metadata — Get available dimensions and metrics for the property. Args: resourceId
• mcp__resources__googleanalytics_run_realtime_report — Run a realtime report showing live activity. Args: resourceId, dimensions?, metrics, limit?
• mcp__resources__googleanalytics_list_accounts — List all GA4 accounts. Args: resourceId, pageSize?, pageToken?
• mcp__resources__googleanalytics_list_properties — List GA4 properties, optionally by account. Args: resourceId, accountId?, pageSize?, pageToken?
• mcp__resources__googleanalytics_list_data_streams — List data streams for a property. Args: resourceId, propertyId?, pageSize?, pageToken?
• mcp__resources__googleanalytics_invoke — Execute any GA4 operation. Args: resourceId, operation, + operation-specific args

TypeScript Client

import { gaClient } from "./clients";

// runReport(dimensions, metrics, dateRanges, invocationKey, options?)
const result = await gaClient.runReport(
	[{ name: "country" }, { name: "city" }],
	[{ name: "activeUsers" }, { name: "sessions" }],
	[{ startDate: "30daysAgo", endDate: "today" }],
	"traffic-by-location",
	{ limit: 100 },
);

// getMetadata(invocationKey)
const metadata = await gaClient.getMetadata("discover-dimensions");

// listAccounts(invocationKey, options?)
const accounts = await gaClient.listAccounts("list-ga-accounts");

// listProperties(invocationKey, accountId?, options?)
const properties = await gaClient.listProperties("list-ga-properties", "accounts/12345");

// runRealtimeReport(metrics, invocationKey, dimensions?, limit?)
const realtime = await gaClient.runRealtimeReport([{ name: "activeUsers" }], "live-users");

Tips

• Property ID format: Use the numeric GA4 property ID (e.g., 123456789), not the measurement ID (G-XXXXXXXX). Find it in GA4 Admin > Property Settings.
• Date ranges: Use relative dates like today, yesterday, 7daysAgo, 30daysAgo, or absolute dates in YYYY-MM-DD format.
• Discover available data: Use get_metadata first to see which dimensions and metrics are available for the property before running reports.
• Dimension/metric names: Use API names like country, city, activeUsers, sessions, screenPageViews — not display names.
• Realtime reports: Do not support date ranges (they show live data only). Only a subset of dimensions/metrics are available.
• Pagination: Use limit and offset for report results, pageSize and pageToken for list operations.
