GSCPAP - Google Search Console, GA4, PageSpeed Insights & live SERPs MCP

GSCPAP - Google Search Console & GA4 MCP Server for Claude, ChatGPT and Cursor

Ask Claude about your Google Search Console data: top queries, decaying pages, ranking trends, quick wins, cannibalization, Core Web Vitals, and GA4 conversions per landing page.

Free. 38 read-only tools. Hosted, so there is no Google Cloud project, no Python and no JSON credentials to manage. You sign in with Google at gscpap.com and connect; the OAuth client is already registered, for everyone.

What it adds

A single MCP server (gsc-pap) exposing 38 tools over the Search Console, Google Analytics 4, PageSpeed Insights and SERP APIs:

Spot quick SEO wins

• find_quick_wins: queries at positions 5 to 20 with at least 100 impressions but under 5% CTR, which is where a title or snippet rewrite pays
• find_cannibalization: several of your URLs competing for one query, splitting the clicks

Find what is losing traffic

• find_content_decay: pages losing organic traffic over time
• historical_position_trend: one query's position over the last N days, trending up, down or just volatile
• compare_periods: diff any two windows, for example the last 28 days against the prior 28
• find_dead_pages: pages appearing for months that have never earned a click, split by whether Google shows them and nobody clicks or barely shows them at all

Beat the 16-month limit

• search_analytics_archive: query your full history, past Google's 16-month retention
• archive_status: per-site coverage, earliest and latest day, row count, last run

See the SERP your rankings live in

• serp_top_results: the live top organic results for a query and country, plus which SERP features are present (featured snippet, map pack, People Also Ask; AI Overviews are reported as unknown)
• serp_competitor_analysis: where your domain sits for a query and the full top 10 around it
• serp_features_audit: up to 25 queries at once, to explain a low CTR at a good position

Diagnose performance and Core Web Vitals

• pagespeed_insights: Lighthouse audit, the four scores, Core Web Vitals and the top opportunities
• pagespeed_field_data: real-user CrUX metrics (LCP, INP, CLS at p75) for a URL and for the origin

Diagnose indexing issues

• get_index_coverage_summary: account-wide breakdown of indexing states
• inspect_url: one URL in depth, straight from the URL Inspection API
• batch_inspect_urls: bulk URL inspection, up to 2,000 URLs
• find_new_pages: pages Search Console started showing this week, and whether each has earned a click yet

Pull performance data

• get_performance_overview: clicks, impressions, CTR and position in one line
• search_analytics_query: the whole Search Analytics surface, any dimension and filter
• get_search_by_page_query: the query mix behind one page

See how AI assistants send you traffic (GEO)

• ga4_ai_traffic: visits from ChatGPT, Perplexity, Gemini, Claude and Copilot, per engine, against organic, and the pages they send people to; property_id="all" compares every site
• find_ai_overview_suspects: queries whose CTR fell while their position held, the footprint an AI Overview leaves

Connect search to engagement and revenue (GA4)

• list_ga4_properties: find the property_id the other GA4 tools need
• ga4_overview: users, sessions, views, bounce and engagement, with a daily breakdown
• ga4_top_pages: top landing pages by sessions
• ga4_traffic_sources: channel, source, medium, campaign
• ga4_realtime: active users in the last 30 minutes
• ga4_conversions_by_source: source and medium with conversions and revenue
• ga4_user_demographics: country, device and browser slices
• ga4_engagement: engagement rate, duration and bounce per page
• ga4_events_by_name: scroll depth, outbound clicks, downloads and custom events, optionally per page
• ga4_compare_periods: diff any window for any GA4 metric
• correlate_gsc_to_ga4: the cross-tool one. Search Console clicks per page joined to GA4 sessions, conversions and revenue for that same page

Manage sites and sitemaps

• list_sites, get_site_details: your verified properties
• list_sitemaps, get_sitemap_details: sitemap health
• detect_duplicate_properties: domain and URL-prefix properties that split your reporting in two

Use it in chat:

Run a Lighthouse audit on https://example.com/pricing and list the top 3 opportunities by potential ms savings.

Pull my Search Console data from January 2024, which is past Google's 16-month retention.

Correlate my Search Console pages with GA4 conversions for the last 28 days. Which top-clicked pages bring zero conversions?

Why is my CTR 1% at position 4 for this query? Check what else is on that SERP.

Install

Claude.ai: add it as a connector (no token, no file)

1. Open the connector settings in Claude.ai: your avatar, then Settings, then Connectors, then "Add custom connector"
2. Paste the URL https://mcp.gscpap.com/mcp
3. Approve the Google sign-in when the client opens it

The server implements OAuth 2.0 with Dynamic Client Registration (RFC 7591), so the client registers itself. Step by step, with screenshots: Add a Search Console connector to Claude.ai.

ChatGPT supports the same flow, but custom MCP connections there are a Business and Enterprise/Edu feature on ChatGPT web, which is OpenAI's rule rather than ours: Connect ChatGPT to Google Search Console.

Claude Code: let Claude install it (about 30 seconds)

1. Open gscpap.com and sign in with Google (read-only Search Console scope)
2. Pick which sites to grant access to. This is a per-site allowlist on top of the OAuth scope
3. On app.gscpap.com/account/tokens, hit + New token, then click Copy install prompt under the Claude Code tab
4. Paste that prompt into any Claude Code session. Claude runs the install command, verifies it, and lists your sites so you can see that it worked

Manual install

If you would rather drive the CLI yourself:

claude mcp add --transport http --scope user gsc-pap https://mcp.gscpap.com/mcp \
  --header "Authorization: Bearer YOUR_TOKEN_HERE"

This plugin variant reads a ${GSC_PAP_TOKEN} env var instead. Set it once:

# macOS / Linux
echo 'export GSC_PAP_TOKEN="paste-your-token-here"' >> ~/.zshrc
source ~/.zshrc

# Windows (PowerShell, persistent)
[Environment]::SetEnvironmentVariable("GSC_PAP_TOKEN", "paste-your-token-here", "User")

Restart Claude Code, or run claude mcp list to check, and the gsc-pap server shows up as Connected.

Setup guides for the other clients (Cursor, VS Code with Copilot, Cline, opencode, Codex CLI, Gemini CLI, Windsurf, Zed, JetBrains, Continue, Warp, Goose, LM Studio, ChatGPT, plain HTTP) are at gscpap.com/integrations.

How it works

• Hosted bridge: mcp.gscpap.com exposes a streamable-HTTP MCP endpoint. We do the OAuth exchange with Google for you and store an encrypted refresh token.
• Per-site allowlist: Google's scope is account-wide (webmasters.readonly), so the server adds a per-user, per-site authorization layer on top. You decide which properties Claude can see.
• Per-token site scope: each token can be narrowed to a subset of your authorized sites, at app.gscpap.com/account/tokens under Edit access. Useful for per-client tokens, a scoped CI token, or limiting the blast radius if a token leaks.
• Rate limits: 30 requests per minute and 500 per hour per token, 60 per minute and 1,000 per hour for the account across all its tokens. Live usage is on app.gscpap.com/account.
• Usage log: every tool call is logged and shown in your own account at app.gscpap.com/account.
• Read-only: nothing in the surface can modify your sites, sitemaps or settings.

Privacy and data

• Your Google refresh token is encrypted at rest with AES-256-GCM; bearer tokens are stored only as SHA-256 hashes
• Aggregate analytics through Google Analytics 4 with IP anonymisation. No marketing pixels, no third-party ad networks. See the Privacy Policy
• Your data is not sold, rented or traded, and it is not used to train AI models. It is shared only with the providers that run the service, which the Privacy Policy names
• Use of data received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements
• Revoke at any time from app.gscpap.com/account/tokens, or from your Google account permissions

Pricing

Free. $0, no credit card, no trial expiry and no feature behind an upgrade prompt. The only ceilings are the rate limits above. Paid plans arrive at v1.0, with at least 60 days notice and a free tier for light use. The full answer, limits included, is at gscpap.com/pricing.
