Quick start

Option A: OAuth (recommended)

1. Create a Google Cloud project and enable the Search Console API
2. Go to Credentials > Create Credentials > OAuth client ID, choose Desktop app
3. Download the client secrets JSON
4. Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json):

{
  "mcpServers": {
    "gsc": {
      "command": "node",
      "args": ["/path/to/Suganthans-GSC-MCP/dist/index.js"],
      "env": {
        "GSC_AUTH_MODE": "oauth",
        "GSC_OAUTH_SECRETS_FILE": "/path/to/client_secrets.json",
        "GSC_SITE_URL": "sc-domain:yoursite.com"
      }
    }
  }
}

First use opens a browser for Google sign in. Token is cached after that.

Option B: Service Account

1. Create a Google Cloud project and enable the Search Console API
2. Go to IAM & Admin > Service Accounts, create one, download the JSON key
3. Add the service account email to your GSC property (Settings > Users and permissions > Full access)
4. Add to your Claude Desktop config:

{
  "mcpServers": {
    "gsc": {
      "command": "node",
      "args": ["/path/to/Suganthans-GSC-MCP/dist/index.js"],
      "env": {
        "GSC_KEY_FILE": "/path/to/service-account.json",
        "GSC_SITE_URL": "sc-domain:yoursite.com"
      }
    }
  }
}

Indexing API (optional)

To use submit_url, submit_batch, and submit_sitemap:

1. Enable the Web Search Indexing API in your Google Cloud console
2. Your service account (or OAuth credentials) need owner-level access in Search Console

Note: Google officially says the Indexing API is for JobPosting and BroadcastEvent schema types. In practice, it processes requests for all page types.

Multi-site

For multiple properties, add GSC_SITE_URLS:

"env": {
  "GSC_SITE_URL": "sc-domain:primarysite.com",
  "GSC_SITE_URLS": "sc-domain:primarysite.com,sc-domain:secondsite.com"
}

content_decay	Pages declining across three consecutive 30-day periods
topic_cluster_performance	Aggregated performance for all pages matching a URL path pattern
ctr_vs_benchmark	Your actual CTR per position vs industry benchmarks
inspect_url	Is this URL indexed? Last crawl date, canonical, robots/noindex issues
check_alerts	Position drops, CTR collapses, click losses, disappeared pages. Severity-rated
content_recommendations	Prioritised actions: pages to update, content to create, pages to consolidate
advanced_search_analytics	Custom queries with flexible dimensions and filters
generate_report	Full markdown report saved to disk
multi_site_dashboard	Health check across all properties in one command

Indexing

What makes this different from other Google Search Console MCP servers

Analysis, not just API access. Most Google Search Console MCP servers wrap the raw API. This one ships with pre-built analysis: opportunity scoring, cannibalisation detection, decay tracking, CTR benchmarking, traffic drop diagnosis. You ask a question, it runs the analysis and tells you what to do.

Hallucination guardrails. Every tool instructs Claude to base analysis only on returned data. Provenance metadata in every response. The verify_claim tool lets Claude fact-check its own numbers. Credit to Krinal Mehta for pushing this.

Visual dashboards. Results render as rich, interactive visualisations in Claude Desktop. Summary cards, colour coded indicators, bar charts, and tabbed sections. Not plain text dumps.

Fresh data. Uses dataState: 'all' so data matches the GSC dashboard, not 2-3 days stale.

Proactive, not reactive. Alerting, content recommendations, and scheduled reports catch problems before you think to look.

Environment variables

Variable	Required	Description
GSC_AUTH_MODE	No	oauth or service_account (default: service_account)
GSC_KEY_FILE	Service account mode	Path to service account JSON key
GSC_OAUTH_SECRETS_FILE	OAuth mode	Path to OAuth client secrets JSON
GSC_OAUTH_CLIENT_ID	OAuth mode (alt)	OAuth client ID
GSC_OAUTH_CLIENT_SECRET	OAuth mode (alt)	OAuth client secret
GSC_SITE_URL	Yes	Primary GSC property URL
GSC_SITE_URLS	No	Comma-separated list for multi-site
