Monorepo checkout

Inside the lomi. monorepo:

git submodule update --init apps/tools/gsc-mcp
cd apps/tools/gsc-mcp
pnpm install
pnpm run build
pnpm auth

Quick start

npx -y @lomi./gsc-mcp auth

Place your Google OAuth desktop client JSON at:

~/.config/lomi-gsc-mcp/oauth_credentials.json

Then add to Cursor:

{
  "mcpServers": {
    "google-search-console": {
      "command": "npx",
      "args": ["-y", "@lomi./gsc-mcp"]
    }
  }
}

Authentication

Choose one:

• Desktop OAuth with PKCE (lomi-gsc-mcp auth)

• Service account JSON via GSC_SERVICE_ACCOUNT_KEY_FILE

• Application Default Credentials for automation

Default OAuth scope is read-only. Set GSC_OAUTH_SCOPE=write and GSC_ENABLE_WRITES=true only when you need sitemap or property mutations.

Self-hosted HTTP

GSC_MCP_TRANSPORT=http \
GSC_MCP_CLIENT_BEARER_TOKEN=replace-me \
GSC_MCP_ALLOWED_HOSTS=localhost \
GSC_MCP_ALLOWED_ORIGINS=http://localhost:3000 \
npx -y @lomi./gsc-mcp-http

Non-loopback HTTP requires GSC_MCP_CLIENT_BEARER_TOKEN.
