# Boolsai Grep

> Parallel regex over every scan in the Boolsai corpus. Part of a three-MCP system (scan + directory + grep). All no-auth, no key.

## What this is

This subdomain (grep.boolsai.ai) hosts the **Grep MCP**. Two sister MCPs share the system:

## Boolsai Grep

- **Connect URL**: `https://grep.boolsai.ai/mcp`
- **What it does**: Parallel regex search across every scan we've ever taken. Use when a signal isn't pre-indexed in the directory — discover new vendor patterns, leaked account IDs, niche tracking pixels.
- **Tools**: `grep_pattern`, `count_pattern`, `sites_with_signal`, `list_signal_types`
- **Sample question**: *"Show me sites with 'window._fs_org' (FullStory) in their inline scripts."*

## Boolsai Scan

- **Connect URL**: `https://boolsai.ai/mcp`
- **What it does**: Live stack scan of any public website. Returns every external host, inline script signature, route, vendor, account ID, and JSON-LD organisation block in one JSON response.
- **Tools**: `boolsai_scan`, `boolsai_scan_paths`
- **Sample question**: *"What is the full tech stack of gymshark.com?"*

## Boolsai Directory

- **Connect URL**: `https://directory.boolsai.ai/mcp`
- **What it does**: Query the pre-indexed Boolsai directory of scanned ecommerce sites. Sub-100ms lookups across tens of thousands of stores.
- **Tools**: `summary`, `site_dossier`, `sites_using_vendor`, `lookup_id`, `brands_in_city`, `brands_in_market`, `stack_archetype`, `compare_sites`, `similar_sites`, `brands_by_founder`
- **Sample question**: *"List ten stores using Klaviyo with their company_id."*
