gsc-mcp

A Model Context Protocol (MCP) server that turns Google Search Console into an SEO copilot for any MCP client (Claude Desktop, Claude Code, Cursor, …). Query search analytics, inspect URLs, manage sitemaps, switch between properties, and surface SEO opportunities — in plain language.

Status: Phase 1. The GSC data layer + multi-site + onboarding are built and working. Coverage-report reconstruction, on-page audits, page-speed, scoring, and a dashboard are on the roadmap — see SPEC.md.

Install & connect (Tier 0: bring-your-own Google client)

A hosted "just sign in" client is coming; for now you create a one-time Google Cloud client.

1. Google Cloud (once):

1. Create or pick a project at https://console.cloud.google.com/.

2. Enable the Google Search Console API (and, later, the PageSpeed Insights API).

3. OAuth consent screen → External → add your Google account as a test user (test users skip app verification).

4. Credentials → Create OAuth client ID → type Desktop app.

5. Copy the Client ID and Client secret.

2. Sign in (once):

GSC_OAUTH_CLIENT_ID=xxx GSC_OAUTH_CLIENT_SECRET=yyy npx -y @ajmalaksar/gsc-mcp login

A browser opens; approve access. The token is stored at ~/.gsc-mcp/token.json (mode 0600). You can also let Claude do this in-conversation with the auth_login tool.

3. Add to your MCP client (Claude Desktop / generic):

{
  "mcpServers": {
    "gsc": {
      "command": "npx",
      "args": ["-y", "@ajmalaksar/gsc-mcp", "serve"],
      "env": {
        "GSC_OAUTH_CLIENT_ID": "xxx",
        "GSC_OAUTH_CLIENT_SECRET": "yyy",
        "GSC_DEFAULT_SITE": "sc-domain:example.com"
      }
    }
  }
}

Claude Code one-liner: claude mcp add gsc -- npx -y @ajmalaksar/gsc-mcp serve.

CLI

gsc-mcp login            Sign in with Google (opens a browser)
gsc-mcp logout           Remove the stored token
gsc-mcp status           Authentication + onboarding status
gsc-mcp setup            Guided first-run
gsc-mcp sites …          Manage the property registry (list / add / remove / default)
gsc-mcp serve            Start the MCP server over stdio (default)

Multi-site

siteUrl is optional on every tool. It resolves in order: explicit arg → session active site → persisted default. Register friendly aliases so you can say "the blog":

gsc-mcp sites add blog sc-domain:example.com
gsc-mcp sites default blog

In chat: use_site switches the active property; account_overview gives a portfolio view across all properties.

Tools (Phase 1)

auth_status, auth_login, list_sites, use_site, get_active_site, set_default_site, account_overview, gsc_deep_link, query_search_analytics, top_queries, top_pages, find_opportunities, compare_periods, inspect_url, list_sitemaps, get_sitemap. With GSC_ENABLE_WRITE=1: submit_sitemap, delete_sitemap.

Develop & extend

npm install
npm run build
npm test

The server is a tool registry. To add a capability, create src/tools/<group>.ts exporting register: ToolModule, then add it to MODULES in src/tools/index.ts. Each module receives the McpServer and a shared ToolContext (auth, GSC client, site resolution). See the architecture notes in SPEC.md.
