Please install the `gtm-ga4` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Google Cloud service account** — Create a GCP service account JSON key with GTM and GA4 access (https://cloud.google.com/iam/docs/service-accounts)

Canonical MCP server config (stdio transport):
- command: `npx`

- required environment variables:
  - `GOOGLE_APPLICATION_CREDENTIALS`: Path to a GCP service account JSON key file (example: `/path/to/service-account.json`)

Note: Sandbox-safety: write operations refuse to target non-sandbox workspaces.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.

Note: Sandbox-safety: write operations refuse to target non-sandbox workspaces.
