Cursor

ChatGPT — add it as a custom connector; see Connect in your AI client below.

A self-hostable Model Context Protocol (MCP) server for Google Search Console. Connect it to Claude.ai, Cursor, ChatGPT, or any MCP-compatible client and ask your AI assistant about your site's organic search performance — impressions, clicks, top queries, index status, and sitemap health — straight from your own Google account.

It runs on Cloudflare Workers and ships with one-click Google OAuth onboarding: connect the server in your client, sign in with Google once, grant the requested Google Search Console permissions, and you're done. No API keys to copy around and no service-account JSON to manage.

Prefer zero setup? The hosted version — with automatic weekly email digests delivered to your inbox — is at digestseo.com. This repository is the open-source core you can run yourself.

Tools

This server exposes 17 tools. Read-only analytics and reporting tools are marked with MCP's readOnlyHint; the write tools below can change Search Console properties, sitemaps, or indexing state.

Tool	Access	What it does
`server.capabilities`	Read	List every tool this server exposes and report whether your Google connection is currently authenticated (`connected` / `not_connected`). Takes no arguments — a good first call for discovery.
`sites.list`	Read	List the Search Console properties the connected Google account can access (`siteUrl`, `permissionLevel`).
`analytics.query`	Read	Impressions, clicks, CTR, and average position over a date range, with dimensions, filters, pagination, and selectable search type.
`urls.inspect`	Read	Google's URL Inspection report for a single page.
`sitemaps.list` / `sitemaps.get`	Read	List submitted sitemaps or retrieve one sitemap's details.
`insights.quick_wins` / `insights.cannibalization` / `insights.content_decay`	Read	Surface optimization opportunities, competing pages, and declining content.
`indexing.list_pages` / `analytics.compare`	Read	Analyze pages receiving impressions and compare two periods.
`reports.weekly_digest`	Read	Generate a plain-language seven-day performance report with movers, top pages, and one recommended action.
`sites.add` / `sites.delete`	Write	Add or remove a Search Console property.
`sitemaps.submit` / `sitemaps.delete`	Write	Submit or remove a sitemap.
`indexing.request`	Write	Requests indexing through Google's Indexing API. Google currently restricts this API to pages containing `JobPosting` structured data or livestream pages containing `BroadcastEvent` inside `VideoObject`. It is not available for general webpage submission.

The server requests Google Search Console and Indexing API scopes. Use a Google account with only the property access you intend to delegate, and review write-tool calls before approving them.

indexing.request eligibility. Google's Indexing API is not a general-purpose page submission tool — as of this writing, Google's own documentation limits it to two content types: pages with JobPosting structured data, and livestream pages with BroadcastEvent structured data nested inside VideoObject. Before submitting, the server fetches the target URL and checks its JSON-LD for one of those two types; if neither is present (or the page can't be fetched), it returns an error explaining why the URL is ineligible instead of calling the Indexing API. A successful submission is only an acknowledgment that Google received the notification — it does not guarantee the URL will be indexed.

What you can ask

Once connected, ask your assistant things like:

"What are my top 20 queries by clicks in the last 28 days?"
"Compare impressions for example.com this month vs last month — which pages dropped?"
"Is https://example.com/pricing indexed? When was it last crawled?"
"Which queries does my blog rank position 5–15 for? Those are my quick wins."
"Give me a weekly digest for sc-domain:example.com ending today."
"Do any of my sitemaps have errors or warnings?"
"Split my clicks into brand vs non-brand using a regex on the query."
"How is my site doing in Google Discover vs regular web search?"

Connect in your AI client

Once you've deployed the server (see SETUP.md), connect it by pasting your Worker's /mcp URL into your client:

https://<your-worker>.workers.dev/mcp

Claude.ai — Settings → Connectors → Add custom connector → paste the /mcp URL. Leave Client ID and Client Secret blank. On first use, Claude opens a Google sign-in flow; grant read access and the connector turns green.
Cursor — add it as a custom MCP server pointing at the same /mcp URL.
ChatGPT (with connector/MCP support) — add a custom connector with the /mcp URL.

Any MCP-compatible client works — they all point at the same /mcp endpoint and share the same OAuth flow.

Setup

Self-hosting means bringing your own Google OAuth credentials and Cloudflare account. The full, copy-pasteable walkthrough is in SETUP.md — including an important note about Google's OAuth verification and the 7-day refresh-token limit while your app is unverified.

Quick shape:

git clone https://github.com/<you>/mcp-gsc.git
cd mcp-gsc
npm install
cp wrangler.example.jsonc wrangler.jsonc       # then paste in your KV ids
# set GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET / TOKEN_ENCRYPTION_KEY as secrets
npm run deploy

See SETUP.md for every step in detail.

Development

npm install
npm test              # typecheck + offline unit tests (what CI runs)
npm run dev           # wrangler dev (local)
npm run test:smoke    # structural smoke tests against a deployment
