# Google Search Console MCP

Read-only MCP server for Google Search Console. Five tools cover the read surface: properties, Search Analytics (filters, auto-pagination past the 25,000-row cap, hourly data), sitemaps, URL inspection, batch inspection with throttling. We run this server in production for every SEO client.

<!-- mcp-name: io.scalably/gsc-mcp -->

## Install

Claude Code:

```bash
claude mcp add gsc -e GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json -- uvx scalably-gsc-mcp
```

Codex:

```bash
codex mcp add gsc --env GOOGLE_APPLICATION_CREDENTIALS=/path/to/service-account.json -- uvx scalably-gsc-mcp
```

Claude Desktop: download `gsc-mcp.mcpb` from the latest GitHub release and open it.

## Setup

1. In Google Cloud, create or pick a project and enable the Google Search Console API on it (APIs and Services, Library).
2. Create a service account in that project and download its JSON key.
3. Add the service account's email as a user on each Search Console property you want to query (Settings, Users and permissions). Full or restricted permission both work for reading.

No OAuth consent screen is needed; the server authenticates as the service account with the `webmasters.readonly` scope.

## Tools (5)

| Tool | What it does |
|---|---|
| `gsc_list_sites` | List the Search Console properties the service account can read |
| `gsc_query_search_analytics` | Query Search Analytics with filters, auto-pagination and hourly data |
| `gsc_list_sitemaps` | List sitemaps for a property or read one sitemap |
| `gsc_inspect_url` | Inspect one URL's index status |
| `gsc_batch_inspect_urls` | Inspect many URLs with client-side throttling |

## Configuration

| Variable | Required | Purpose |
|---|---|---|
| `GOOGLE_APPLICATION_CREDENTIALS` | yes | Path to a Google service-account JSON file with the Search Console read-only scope; share each property with the service account email |
| `GSC_LOG_LEVEL` | no | INFO (default) or DEBUG |
| `GSC_RETRY_BASE_SECONDS` | no | Base delay in seconds for the retry backoff on transient API errors (default 1) |
| `GSC_WEBMASTERS_BASE`, `GSC_SEARCHCONSOLE_BASE` | no | Override the two Google API base URLs (used by the test suite to point at a local fake; leave unset in normal use) |
| `GSC_TEST_ACCESS_TOKEN` | no | Test-suite only: a literal bearer token that bypasses the service account. Never set it in normal use |

## Reply shape

Every tool returns JSON with `status` (`succeeded`, `partial`, `no_op`), `summary`, `result`, `proof`, `warnings`, `recovery`. A `partial` status with `proof.nextStartRow` means: continue from that row.

## Limits

25,000 rows per Search Analytics call (the server auto-paginates past it up to `max_rows`). URL inspection: Google allows 600 per minute and 2,000 per day per property. The server paces batch inspection client-side (default 8 requests per second) and warns when a batch exceeds the daily quota; it does not track daily usage across calls, so keep your own count.

## Verify

Each release lists the package version, the `.mcpb` sha256 and the production commit it was derived from in CHANGELOG.md. CI runs the tests and a clean install of the built wheel on every push.
