npm run build

Configuration

Service Account Setup

1. Create a Google Cloud service account with Search Console API access
2. Download the JSON key file
3. Add the service account email as a user in Google Search Console for each property

Config File

Create a config.json in the project root (see config.example.json for the full structure):

{
  "default_credentials": "/path/to/service-account-key.json",
  "clients": {
    "my-project": {
      "site_url": "sc-domain:example.com",
      "credentials": "/path/to/service-account-key.json"
    }
  }
}

Environment Variable

Alternatively, set GOOGLE_APPLICATION_CREDENTIALS to the path of your service account key file. The config file takes precedence when present.

Usage

Add to your Claude Code .mcp.json:

{
  "mcpServers": {
    "gsc": {
      "command": "node",
      "args": ["/path/to/mcp-gsc/dist/index.js"]
    }
  }
}

Or if installed globally:

{
  "mcpServers": {
    "gsc": {
      "command": "npx",
      "args": ["mcp-gsc"]
    }
  }
}
