27 read tools · Read-only by design.

Run locally with your own platform credentials and a client that supports stdio MCP, such as Claude Desktop, Claude Code or Cursor. Your requests go directly to the platform. For managed connections, including supported ChatGPT setups, use the hosted option.

What's new

v2.1.0: Property allowlist and revoked-token handling · October 23, 2026

• Add the optional GA4_PROPERTY_IDS allowlist, checked before every request. ga4_list_properties, ga4_list_accounts and ga4_health_check list only the allowed properties and the accounts that hold them. Unset, the server prints a recommendation on stderr. It becomes required in 3.0.0.
• Refuse a GA4_PROPERTY_ID outside GA4_PROPERTY_IDS at startup, when both are set.
• Port the gateway's handling of a refused refresh token (invalid_grant, admin_policy_enforced): one re-authorization message naming GA4_REFRESH_TOKEN, and no further token requests until restart.
• Give the token request a deadline and bound every response body.
• Require Node.js ^22.23.4 || ^24.22.1 || >=26.12.1, warn on stderr at startup and in npm run doctor on older releases, and test Node 22, 24 and 26 in CI.
• Update @modelcontextprotocol/sdk to 1.32.1 and regenerate the lockfile.
• Publish from version tags with release.yml, which replaces publish-mcp.yml. Add Dependabot.
• No tool is added or removed: 27 read tools, no write tools.

Upgrade notes

Requires Node.js 22.23.4, 24.22.1 or 26.12.1, or a newer release of one of these lines. Older releases lack the October 2026 security fixes, and the server prints a warning on stderr when it starts on one. CI covers Node 22, 24 and 26.

This release makes no breaking change to the configuration. One change is announced for 3.0.0: GA4_PROPERTY_IDS is optional in 2.x and becomes required. When set, every tool is limited to the listed properties, and GA4_PROPERTY_ID must be one of them. When unset, the server starts as before and prints one line on stderr recommending it. The tools and their schemas are unchanged.

What you get

Compatibility, checked before the call

GA4 rejects many metric and dimension combinations, and its errors rarely explain which pair is at fault. This server carries the compatibility matrix, so ga4_check_compatibility and ga4_validate_query let the model verify a combination before spending a call and a quota token on it.

Quotas matter here more than on ad platforms: GA4 charges tokens per property per day, and a few careless exploratory queries can exhaust them. ga4_get_property_quotas_snapshot shows what is left.

Read-only, and why it stays that way

There are no write tools, and no environment variable that adds any. Every tool calls a read method of the Data API or the Admin API.

This is not caution for its own sake. A misread report is a wrong answer you can spot. A mistaken write to an analytics property, a deleted audience or an edited data stream, corrupts the record you use to judge everything else, and often silently. The other servers we publish do have write tools, guarded by a mandatory preview. This one has none.

Personal data

Analytics data is not anonymous by default. A GA4 property can carry a userId you set yourself, a device identifier, or a Google Signals pseudonymous ID. An MCP conversation sends whatever a tool returns to a model.

Identifiers are redacted by default wherever this server can return them, and showing them is an explicit opt-in, never the default.

Every one of these accepts includePersonalIdentifiers: true to return raw values, and defaults to false.

Audience export rows are positional, so the redaction reads the export's dimension metadata to find identifier columns. If that metadata is missing, every value in the row is redacted rather than guessing which column is safe. Failing closed is the point.

Report rows are not redacted. ga4_run_report and the other reporting tools return what you asked for. Altering the numbers a report returns would be worse than returning them.

So one decision stays yours: if your property carries a userId you consider personal, do not request it as a report dimension in a conversation whose transcript leaves your machine.

Getting credentials

Three values, obtained once.

1. OAuth client

In a Google Cloud project, enable the Google Analytics Data API and the Google Analytics Admin API, then create an OAuth client under APIs & Services → Credentials. Choose Desktop app for local use. Note the client ID and client secret.

2. Refresh token

Run the OAuth consent flow once, signed in as a Google account with access to your GA4 properties, and keep the refresh token. The analytics.readonly scope is enough, and it is the only one you should grant.

📖 Google OAuth for installed apps

The refresh token does not expire. It is the sensitive value: anyone holding it can mint access tokens indefinitely. Use an OAuth client dedicated to this server so you can revoke it on its own.

3. Property ID, optional

Set GA4_PROPERTY_ID to avoid passing it on every call. Find it in GA4 under Admin → Property Settings, or list them with ga4_list_properties.

Run ga4_health_check as your first call. It verifies the credentials and lists the properties you can actually reach, without printing any secret.

Setup

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "google-analytics": {
      "command": "npx",
      "args": ["-y", "@getmcpads/google-analytics-mcp-server"],
      "env": {
        "GA4_CLIENT_ID": "your-client-id",
        "GA4_CLIENT_SECRET": "your-client-secret",
        "GA4_REFRESH_TOKEN": "your-refresh-token",
        "GA4_PROPERTY_IDS": "123456789"
      }
    }
  }
}

Restart Claude Desktop. Ask it: "list my Google Analytics properties".

Claude Code

claude mcp add google-analytics --env GA4_CLIENT_ID=... --env GA4_CLIENT_SECRET=... --env GA4_REFRESH_TOKEN=... -- npx -y @getmcpads/google-analytics-mcp-server

Cursor

.cursor/mcp.json in your project, same shape as the Claude Desktop config above.

From source

git clone https://github.com/get-mcp-ads/google-analytics-mcp-server.git
cd google-analytics-mcp-server
npm install && npm run build
cp .env.example .env   # then fill in your credentials
npm start

Security

• The client secret and refresh token are never logged, at any log level, or written to disk.
• A revoked refresh token is reported once. When Google answers invalid_grant, every later call returns the same message with the steps to authorize again, and the server stops asking Google for a token until it restarts.
• Properties can be limited. With GA4_PROPERTY_IDS set, a call naming another property is refused before any request, and discovery lists only the allowed properties.
• Three hosts are contacted, and only three: analyticsdata.googleapis.com, analyticsadmin.googleapis.com and oauth2.googleapis.com. A test fails the build if a fourth host appears in the source.
• No fetch follows a redirect. Every outbound call sets redirect: "error", so a redirect cannot forward a bearer token or client secret to another host. A test fails the build if any fetch omits this.
• No telemetry. The server makes no network call other than to Google.

Looking for a managed, multi-platform version?

Try hosted GA4 if you want to use this source without operating a local server. getmcpads also connects advertising, Search Console and GA4 through one MCP URL. Source availability and plan limits are listed on the site; connecting an account is still required.

1. Follow the GA4 connection guide.
2. Select the account or property your assistant may read.
3. Connect Claude, ChatGPT or Codex.
4. Try a read-only review: “Compare acquisition channels, landing pages and configured key events. State missing data and do not change anything.”

See the current hosted tool catalogue and pricing before choosing a paid plan. This Apache 2.0 adapter remains independently useful with your own credentials.

MCP contracts and desktop bundle

Every tool declares read/write annotations, parameter descriptions and a structured output schema. Successful calls expose the payload as structuredContent.result; errors retain isError: true. The generated server card contains definitions only.

Run npm run bundle -- /path/to/output to build a .mcpb desktop bundle from the current catalog. Credentials are entered locally during installation. This server remains read-only.
