Boolsai Grep

Gives you regex search across Boolsai's entire corpus of ecommerce tech stack scans stored in R2. Four tools: `grep_pattern` for raw regex matches, `count_pattern` for frequency analysis, `sites_with_signal` to find which domains contain a specific pattern, and `list_signal_types` to see what's indexed. Useful when you need to discover new vendor fingerprints, hunt for leaked account IDs, or spot niche tracking pixels that aren't pre-indexed in the Directory server. Runs parallel searches across hundreds of thousands of historical scans. No auth required, connects via streamable HTTP. Part of the four-server Boolsai suite but works standalone if you just need pattern matching across live commerce site data.
