# OnCrawl MCP Server

MCP server that exposes OnCrawl's API for use with Claude Code and Claude Desktop. Enables Claude to perform deep technical SEO analysis by querying crawl data, Google Search Console metrics, and crawl-over-crawl comparisons.

## Features

- **12 MCP Tools** for comprehensive SEO analysis
- **Raw data access**: Query pages, links, clusters, structured data with flexible OQL
- **Schema discovery**: Claude learns available fields before querying
- **Aggregations**: Group/count by any dimension for pattern detection
- **Full exports**: No 10k limit for complete datasets
- **Crawl-over-crawl analysis**: Track changes between crawls (new pages, status changes, etc.)
- **Google Search Console integration**: 600+ GSC fields including clicks, impressions, CTR, position by device, brand/non-brand, and more
- **Google Analytics 4 integration**: Session, user, and engagement metrics

## What Makes This Powerful

OnCrawl combines crawl data with GSC/GA4 traffic data, enabling analyses like:

- **Orphan pages with traffic**: Pages getting clicks from Google but not linked internally
- **Underlinked high-performers**: Popular pages with weak internal linking
- **Low CTR opportunities**: Pages with high impressions but poor click-through rates
- **404s still in Google**: Broken pages still appearing in search results
- **Deep pages with traffic**: Buried content that Google values
- **Mobile vs desktop performance**: Traffic breakdowns by device

## Prerequisites

- Python 3.11+
- OnCrawl account with API access
- OnCrawl API token (from your OnCrawl settings)

## Installation

### Option 1: Install from PyPI (Recommended)
