Boolsai — MCP server suite
Stack-intelligence MCPs for AI agents. Live, no-auth, public access to every commerce site's tech stack — every vendor, every account ID, every inline script signature, plus a quant-research signal layer on top.
Built for AI agents doing competitive intel, agency prospect research, ecommerce due diligence, and ad-hoc commerce-data discovery.
This repo contains the Anthropic MCP Registry manifests for the four-server Boolsai suite. The actual servers live at *.boolsai.ai.
The four servers
| Server | Connect URL | Tools | What it does |
|---|---|---|---|
| Boolsai Scan | https://boolsai.ai/mcp | boolsai_scan, boolsai_scan_paths | Live tech-stack scan of any public site. Returns every external host, inline script signature, route, vendor, account ID, and JSON-LD organisation block in one response. |
| Boolsai Directory | https://directory.boolsai.ai/mcp | summary, site_dossier, sites_using_vendor, lookup_id, brands_in_city, brands_in_market, stack_archetype, compare_sites, similar_sites, brands_by_founder | Pre-indexed directory of tens of thousands of ecommerce sites by vendor, account ID, country, founder, city, archetype. |
| Boolsai Grep | https://grep.boolsai.ai/mcp | grep_pattern, count_pattern, sites_with_signal, list_signal_types | Parallel regex search across the R2 corpus of every scan we've ever taken. Use when a signal isn't pre-indexed — discover new vendor patterns, leaked account IDs, niche tracking pixels. |
| Boolsai Signals | https://signals.boolsai.ai/mcp | universe_summary, find_signals, test_filter, recent_events, event_dossier, scan_at_date, ticker_history | Quant-research MCP. Hunts for tradeable signals in 316 public-company website stack changes (1,761 events), SPY-benchmarked. Wayback Machine integration. Methodology baked into the initialize response. |
Each server is independently published to the Anthropic MCP Registry under the ai.boolsai/* namespace (DNS-verified via boolsai.ai).
Why Boolsai
- No auth, no key, no rate limit gymnastics. Paste a URL into Claude.ai → Settings → Connectors. Done.
- First-party data. Every scan runs live on demand. No third-party feeds, no stale catalogue.
- Built for AI consumption. Each server's
initializeresponse includes a detailedinstructionsblock — vendor recognition tips, output schemas, methodology. Agents don't have to guess. - Suite, not silo. Cross-discovery: each server's instructions reference the other three so agents can chain queries (scan → look up in directory → grep historical → test as signal).
