GA4 SEO MCP

io.github.GermaniUPublished by GitHub account GermaniUv0.1.2Updated Nov 7, 2026

Set up and audit site measurement: GA4, Search Console and PageSpeed. Read-only unless enabled.

Overview

AI-generated overview

Local MCP server for GA4, Search Console and PageSpeed Insights: read reports, audit SEO data, and optionally set up site measurement.

What you can do
  • List GA4 accounts, properties, data streams, key events, custom dimensions and Ads links
  • Run GA4 reports, realtime reports, top pages, events, traffic sources, conversions and multi-property portfolio audits
  • Query Search Console sites, top queries, page performance, per-page query breakdowns and sitemaps
  • Run PageSpeed Insights audits and CrUX field data checks on public URLs
  • Plan or apply a full site measurement setup with bootstrap_site_measurement, plus optional keyword research via DataForSEO and Google Ads Keyword Planner
When to use it
Useful when you work with Google Analytics 4, Search Console or Core Web Vitals data and want an assistant to pull reports, audit a site's tracking, or plan and apply a new site's measurement setup from one conversation.
Requirements
Runs locally over stdio via uvx (uv 0.13.4+) or Docker. Needs Google credentials: a service account key file via GOOGLE_APPLICATION_CREDENTIALS or Application Default Credentials from gcloud, usually with your own OAuth client. Optional: PAGESPEED_API_KEY, DATAFORSEO_LOGIN and DATAFORSEO_PASSWORD, GOOGLE_ADS_DEVELOPER_TOKEN, GOOGLE_ADS_LOGIN_CUSTOMER_ID. Toolsets chosen with GA4SEO_TOOLSETS.
Before you install
Write tools that create, update, delete, submit or verify are only registered when GA4SEO_ENABLE_WRITES=1 or --enable-writes is set; applying a bootstrap plan changes real GA4 and Search Console configuration, so review the plan first. Credentials and secrets (service account key, DATAFORSEO_PASSWORD, GOOGLE_ADS_DEVELOPER_TOKEN, PAGESPEED_API_KEY) are read from environment variables or a restricted file. DataForSEO keyword data is paid. HTTP mode should use MCP_AUTH_TOKEN.

Installation

In SourceWeft

  1. Open GA4 SEO MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

ga4-seo-mcp — site measurement for AI agents, end to end

Get a site's measurement ready end to end: GA4 + Search Console + PageSpeed, with optional, guarded writes. An open source Model Context Protocol server for Google Analytics 4 & Search Console. Most MCP servers for Google read your data; this one can also set it up: property, web stream, key events, custom dimensions, Search Console DNS verification, sitemap and a PageSpeed baseline — read-only until you say otherwise.

[An agent audits a public site with PageSpeed and plans the GA4 + Search Console setup of a new site]

Real run: psi_audit on a public site and bootstrap_site_measurement(apply=False) planning a new site. The demo script redacts the account ID.


💡 Why this one?

Launching a site means the same chores every time: create the GA4 property and its web stream, mark the key events, register custom dimensions, add the domain to Search Console, publish a DNS TXT record, verify it, submit the sitemap, and record a PageSpeed baseline. ga4-seo-mcp turns that into one plan your agent shows you, and one confirmation.

Based on each project's README on 2026-10-19; "—" means we did not find it documented. Corrections welcome. Those projects go wider than this one (Bing, AdSense, WordPress, GEO audits…); this one goes deeper on setting up measurement.

🤝 Need this done for you?

This server is built and maintained by Germani Uicab. If you'd rather not run it yourself, ServerStack Solutions can get your GA4 + Search Console measurement ready: a written plan, property and key events configured, the DNS verification and sitemap in place, and a PageSpeed baseline — with a QA pass before handover.


Extras: optional keyword research with DataForSEO (exact long-tail volumes) and Google Ads Keyword Planner (free, bucketed volumes), with es-MX defaults that you can override.


⚡ Quick start

1. Install uv 0.13.4 or newer — the client launches the server with uvx; nothing else to install.

2. Log in with the minimum scopes. The CLI prints the exact gcloud command for the toolsets you enable:

bash
uvx ga4-seo-mcp auth-command --client-id-file=oauth-client.json# gcloud auth application-default login --client-id-file=oauth-client.json --scopes=https://www.googleapis.com/auth/cloud-platform,https://www.googleapis.com/auth/analytics.readonly,https://www.googleapis.com/auth/webmasters.readonly

Run the printed command. Google blocks Analytics and Search Console scopes on gcloud's built-in OAuth client, so you need your own (a one-time, few-minute setup) or a service account — both are explained in docs/AUTH.md.

3. Check everything before connecting a client (read-only, changes nothing):

bash
uvx ga4-seo-mcp doctor# [ok] credentials found: Credentials via Application Default Credentials# [ok] access token refreshed# [ok] token has the 2 scope(s) these toolsets need# [ok] admin: <n> account(s) visible on the first page# [ok] data: responded (<n> metrics in the schema)# [ok] gsc: <n> site(s) visible# [ok] psi: no Google login needed; PAGESPEED_API_KEY set# all checks passed

4. Add it to your client (Claude Code shown; others below):

bash
claude mcp add ga4-seo -- uvx ga4-seo-mcp

Ask: "List my GA4 properties and show last week's sessions for the first one."


🧰 Toolsets, scopes and tools

Enable only what you need with --toolsets (or GA4SEO_TOOLSETS). Default: admin,data,gsc,psi. Only the tools of active toolsets are registered, and the OAuth scopes follow.

Tool counts from the real registry: 24 with the defaults, 37 with --enable-writes, 8 with --toolsets data, 41 with every toolset and writes. The full list with descriptions is in docs/TOOLS.md (generated from the registry and checked in CI).

Prompts: audit_ga4_setup, seo_360_audit, portfolio_performance_digest and launch_site_measurement (the guided flow: plan → your confirmation → apply → DNS verification → sitemap → PageSpeed baseline).

bootstrap_site_measurement

text
bootstrap_site_measurement(site_url="https://example.com", account_id="123456789",                           property_display_name="Example", time_zone="America/Mexico_City",                           currency_code="USD", key_events=["generate_lead"],                           custom_dimensions=[{"parameter_name": "plan_type", "display_name": "Plan type"}])
  • apply=False (default): a plan. Read-only and always registered. It finds the existing property and web stream by the site's domain, the key events and custom dimensions already declared, and the Search Console domain property, and lists what would be created.
  • apply=True: executes the plan. Only works when the server runs with --enable-writes; otherwise it fails before touching anything. Idempotent: it skips what exists, so you can re-run it. Returns a step-by-step report with the measurement ID (G-…) and the DNS TXT token.
  • DNS verification (sc_verify_site_dns) and the sitemap (sc_submit_sitemap) stay explicit follow-up steps: you have to publish the TXT record first.

🔒 Security model

Defaults are safe for a single user on a laptop. Details and threat model: SECURITY.md.

  • Read-only by default. Without --enable-writes (or GA4SEO_ENABLE_WRITES=1), tools that create, update, delete, submit or verify are not registered at all — the model cannot call what does not exist.
  • MCP annotations on every tool: readOnlyHint on reads, destructiveHint on deletes and updates, idempotentHint where repeating is harmless, openWorldHint everywhere. Clients that honor them can auto-approve reads and ask before writes.
  • Minimum scopes: each Google client requests only the scope of the call it makes; auth-command asks only for the scopes of your toolsets.
  • HTTP transport (--transport streamable-http): binds to 127.0.0.1, DNS-rebinding protection on, CORS off unless MCP_CORS_ORIGINS, and an optional bearer token MCP_AUTH_TOKEN (401 without it). Listening on 0.0.0.0 without a token prints a warning, and LAN clients need MCP_ALLOWED_HOSTS or the rebinding protection answers 421.
  • Secrets (DataForSEO, Ads developer token, PageSpeed key) come only from environment variables or a chmod 600 file, and are never logged or returned in errors.

⚙️ Configuration

VariableDefaultDescription
GOOGLE_APPLICATION_CREDENTIALS—Service account key file. Unset = Application Default Credentials from gcloud.
GA4SEO_TOOLSETSadmin,data,gsc,psiSame as --toolsets.
GA4SEO_ENABLE_WRITES01 = same as --enable-writes.
PAGESPEED_API_KEY—Recommended: the anonymous PageSpeed quota is shared and often exhausted (429).
DATAFORSEO_LOGIN, DATAFORSEO_PASSWORD—dataforseo toolset.
GOOGLE_ADS_DEVELOPER_TOKEN—ads toolset, or ~/.config/ga4-seo-mcp/dev-token with chmod 600.
GOOGLE_ADS_LOGIN_CUSTOMER_ID—Only when operating through a manager (MCC) account.
MCP_TRANSPORTstdiostdio, streamable-http or sse.
MCP_HOST / MCP_PORT127.0.0.1 / 8000HTTP bind address and port. A specific non-loopback address is added to the allowed Host headers; 0.0.0.0 is not, so set MCP_ALLOWED_HOSTS for LAN clients.
MCP_AUTH_TOKEN—Require Authorization: Bearer <token> on every HTTP request.
MCP_CORS_ORIGINS—Comma-separated exact origins for a browser client. Never *.
MCP_ALLOWED_HOSTS—Comma-separated host/IP values clients use (e.g. 192.168.1.10). Required when binding 0.0.0.0 and connecting over the LAN; DNS-rebinding protection rejects everything else with 421.

Copy .env.example as a starting point.


🔌 Connect your client

Every client launches the server over stdio. Add --enable-writes to args only for the session where you actually want to set up a site.

Docker (stdio). Mount your credentials file read-only — the ADC file from gcloud or a service account key — and run as your own user so the container can read a 0600 file:

bash
docker run -i --rm --user "$(id -u):$(id -g)" \  -v ~/.config/gcloud/application_default_credentials.json:/creds/credentials.json:ro \  -e GOOGLE_APPLICATION_CREDENTIALS=/creds/credentials.json \  ghcr.io/germaniu/ga4-seo-mcp

HTTP (several clients sharing one server):

bash
MCP_AUTH_TOKEN=$(openssl rand -hex 32) uvx ga4-seo-mcp --transport streamable-http# endpoint: http://127.0.0.1:8000/mcp  (send Authorization: Bearer <token>)

🩹 Troubleshooting

SymptomCause and fix
This app is blocked / access_denied during gcloud ... logingcloud's built-in client cannot request Analytics or Search Console scopes. Use your own OAuth client (--client-id-file) and add yourself as a Test User of its consent screen — docs/AUTH.md.

list_account_summaries

List every GA4 account you can access, with a summary of its properties. Start here to find the account_id and property_id the other tools need.

Takes no parameters.

list_properties

List the GA4 properties under an account. Args: account_id: numeric account ID or 'accounts/123456789'. include_deleted: also return properties in the trash (soft-deleted, kept 35 days).

Parametersaccount_idrequiredinclude_deleted

get_property

Get the full settings of a GA4 property (time zone, currency, industry, type).

Parametersproperty_idrequired

list_data_streams

List the data streams (web, iOS, Android) of a GA4 property. Web streams include their measurement ID (G-XXXXXXX) and default URI.

Parametersproperty_idrequired

get_data_stream

Get one data stream, including the measurement ID of a web stream.

Parametersstream_idrequiredproperty_idrequired

list_key_events

List the key events (formerly conversions) declared on a GA4 property.

Parametersproperty_idrequired

list_custom_dimensions

List the custom dimensions declared on a GA4 property, with their scope.

Parametersproperty_idrequired

bootstrap_site_measurement

Plan, and optionally apply, the full measurement setup of a website. With apply=False (default) nothing is changed: it detects what already exists for the site (GA4 property and web stream matched by the site's domain, key events, custom dimensions, Search Console domain property) and returns the steps that would run. Show this plan to the user and get explicit confirmation before calling apply=True. With apply=True (requires the server to run with --enable-writes) it creates only the missing pieces, skipping what exists, so it is safe to re-run. It returns a step-by-step report with the GA4 measurement ID (G-...) and the DNS TXT token for Search Console. DNS verification and sitemap submission stay manual follow-up steps (sc_verify_site_dns, sc_submit_sitemap) because the TXT record must be published first. Args: site_url: the site, e.g. 'https://example.com'. account_id: GA4 account that owns (or will own) the property; see list_account_summaries. property_display_name: name for a new property; also used to find an existing one. time_zone: IANA time zone for a new property, e.g. 'America/Mexico_City'. currency_code: ISO 4217 currency for a new property, e.g. 'USD'. key_events: event names to mark as key events, e.g. ['generate_lead']. custom_dimensions: parameters to register as custom dimensions. apply: False = plan only (default); True = execute the plan.

run_report

Run a flexible GA4 report. Args: property_id: numeric ID or 'properties/123456789'. metrics: e.g. ['sessions', 'activeUsers', 'keyEvents']. Catalog: https://developers.google.com/analytics/devguides/reporting/data/v1/api-schema#metrics dimensions: optional, e.g. ['date', 'sessionSource', 'pagePath']. Catalog: https://developers.google.com/analytics/devguides/reporting/data/v1/api-schema#dimensions date_start: 'YYYY-MM-DD', 'today', 'yesterday' or 'NdaysAgo' (e.g. '28daysAgo'). date_end: same formats as date_start. limit: maximum rows (default 25). order_by_metric: sort by this metric, e.g. 'sessions'. order_desc: sort descending (default True). Returns the dimension and metric names, the date range, row_count and the rows.

web_vitals_summary

Core Web Vitals reported by your own site as GA4 events. Requires the site to send web-vitals events with the parameters `web_vital_metric` and `web_vital_rating`, both registered as event-scoped custom dimensions. For Google's field data use psi_field_data_only instead.

Parametersdate_enddate_startproperty_idrequired

audit_portfolio

Summary metrics for several GA4 properties in one call. Returns sessions, active users, conversions, bounce rate and average session duration per property, plus the properties that failed and why. Args: property_ids: e.g. ['123456789', '987654321'].

Parametersdate_enddate_startproperty_idsrequired

sc_list_sites

List the Search Console sites you can access. Each entry has `siteUrl` ('sc-domain:example.com' for domain properties or a URL prefix like 'https://example.com/') and `permissionLevel` ('siteOwner', 'siteFullUser', 'siteRestrictedUser' or 'siteUnverifiedUser').

Takes no parameters.

Parameterssite_urlrequired

psi_audit

Run a PageSpeed Insights audit (Lighthouse lab test + CrUX field data) on a public URL. Takes 30-90 seconds. Without PAGESPEED_API_KEY the anonymous quota is small and Google may answer 429; set the key for regular use. Args: url: absolute public URL, e.g. 'https://example.com/'. strategy: 'mobile' (default) or 'desktop'. categories: subset of ['performance', 'accessibility', 'best-practices', 'seo']. Default: all four. Returns 0-100 category scores, lab Core Web Vitals (LCP, FCP, CLS, TBT, SI, TTFB) and, when Chrome has enough real-user traffic, CrUX p75 field data for the URL and its origin.

Parametersurlrequiredstrategycategories

psi_field_data_only

Only the CrUX field data (real Chrome users, p75 over 28 days) for a URL and its origin. PageSpeed Insights still runs a performance-only Lighthouse pass, so expect 15-40 seconds. `overall_category` is FAST, AVERAGE or SLOW; it is null when the page has too little traffic.
