Quick Start

# Install globally
npm install -g @appsyogi/gsc-mcp-server

# Set up OAuth credentials
gsc-mcp init

# Verify setup
gsc-mcp doctor

# Start the server (for MCP clients)
gsc-mcp run

Prerequisites

1. Create Google Cloud OAuth Credentials

You need to create your own OAuth credentials in Google Cloud Console:

1. Go to Google Cloud Console
2. Create a new project or select an existing one
3. Enable the Google Search Console API:
   • Go to "APIs & Services" → "Library"
   • Search for "Google Search Console API"
   • Click "Enable"
4. Create OAuth credentials:
   • Go to "APIs & Services" → "Credentials"
   • Click "Create Credentials" → "OAuth client ID"
   • Choose "Desktop application"
   • Name it (e.g., "GSC-MCP")
   • Click "Create"
5. Copy the Client ID and Client Secret
6. Add test users (required while app is in testing mode):
   • Go to "APIs & Services" → "OAuth consent screen"
   • Scroll to "Test users" section
   • Click "Add users"
   • Add the Google account email(s) you'll use to authenticate
   • Click "Save"

Note: While your app's publishing status is "Testing", only test users can authenticate. You can add up to 100 test users.

2. Configure GSC-MCP

Run the init command and enter your credentials:

gsc-mcp init

This will:

• Prompt for your Client ID and Client Secret
• Open a browser for Google authentication
• Store your refresh token securely in the OS keychain

Usage

CLI Commands

# Initialize with OAuth (interactive)
gsc-mcp init

# Initialize with service account
gsc-mcp init --service-account /path/to/key.json

# Initialize with full scope (for sitemap submission, URL inspection)
gsc-mcp init --scope full

# Check configuration and connectivity
gsc-mcp doctor
gsc-mcp doctor --verbose

# Start MCP server (stdio mode)
gsc-mcp run

# Start in HTTP mode (for debugging)
gsc-mcp run --http 3333

# View current configuration
gsc-mcp config

# Clear credentials
gsc-mcp logout

MCP Client Configuration

Claude Desktop

Add to your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {

LLM Optimization (v0.2.0+)

All tools support parameters to reduce token consumption for LLM use cases:

Compact Response Format

Add format: "compact" to any tool for LLM-optimized output:

{
  "siteUrl": "sc-domain:example.com",
  "startDate": "2026-01-01",
  "endDate": "2026-01-28",
  "dimensions": ["query"],
  "format": "compact"
}

Compact format features:

• Short key names (imp instead of impressions, pos instead of position)
• CTR as percentage string ("5.41%" instead of 0.054123...)
• Natural language summary field
• URL prefixes stripped from page paths

Example compact response:

{
  "summary": "Top query 'example keyword' got 150 clicks at position 3.2",
  "rows": [
    {"key": "example keyword", "clicks": 150, "imp": 2800, "ctr": "5.36%", "pos": 3.2}
  ]
}

Date Rollup Granularity

For date dimension queries, use granularity to reduce row count:

{
  "siteUrl": "sc-domain:example.com",
  "startDate": "2025-07-01",
  "endDate": "2026-01-28",
  "dimensions": ["date"],
  "granularity": "weekly"
}

Options:

• daily — Default, returns daily data
• weekly — Aggregates by week (Monday-based)
• monthly — Aggregates by month
• auto — Picks based on date range (>90 days = monthly, >21 days = weekly)

Default Row Limits

Default rowLimit is 25 (optimized for LLM context windows). Use higher values when needed:

{
  "siteUrl": "sc-domain:example.com",
  "rowLimit": 100
}

Maximum: 25,000 rows.

Resources

The server exposes browsable resources:

• gsc://sites — List all properties
• gsc://sites/{siteUrl}/sitemaps — List sitemaps for a property

Scopes

GSC-MCP supports two permission levels:

Readonly (default)

• Search analytics queries
• List sitemaps
• SEO analysis tools

gsc-mcp init  # Uses readonly by default

Full

• Everything in readonly, plus:
• Submit/delete sitemaps
• URL inspection

gsc-mcp init --scope full

Configuration Files

GSC-MCP stores configuration in platform-specific locations:

Files:

• config.json — OAuth client ID/secret, scope settings
• cache.sqlite — Query cache and saved presets

Tokens are stored securely in the OS keychain when available.

Service Account Setup

For automated/server use, you can use a service account instead of OAuth:

1. Create a service account in Google Cloud Console
2. Download the JSON key file
3. Add the service account email as an owner in Google Search Console
4. Initialize:

gsc-mcp init --service-account /path/to/key.json

API Quotas

Google Search Console API has a default quota of 1,200 queries per day. GSC-MCP includes:

• Automatic retry with exponential backoff
• Query caching to reduce API calls
• Pagination handling for large result sets

Examples

Find Quick-Win Keywords

Use gsc-mcp to find quick-win opportunities for my site https://example.com

Weekly Report

Generate a weekly performance summary for https://example.com

Compare Periods

Compare search performance for https://example.com between last week and the week before

Export Data
