Common questions

Is Boolsai Signals safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 6 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Context7, Codebase Memory, Exa

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](./boolsai-scan/server.json)	`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](./boolsai-directory/server.json)	`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](./boolsai-grep/server.json)	`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](./boolsai-signals/server.json)	`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 initialize response includes a detailed instructions block — 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).

Install

Claude Desktop / Claude Code / Cursor

"mcpServers": { "boolsai-scan": { "url": "https://boolsai.ai/mcp" }, "boolsai-directory": { "url": "https://directory.boolsai.ai/mcp" }, "boolsai-grep": { "url": "https://grep.boolsai.ai/mcp" }, "boolsai-signals": { "url": "https://signals.boolsai.ai/mcp" } } }

Restart the client. All four servers show up with their tools.

ChatGPT / Claude.ai Custom Connectors

Settings → Connectors → Add custom connector → paste any of the four URLs above. Add all four for the full suite.

One-liner test from a terminal

curl -sS https://boolsai.ai/mcp \

-H 'content-type: application/json' \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' | jq .

Example agent prompts

"What's the full tech stack of gymshark.com?"

→ boolsai_scan({ url: "https://gymshark.com" })

"List ten stores using Klaviyo with their company IDs."

→ boolsai-directory.sites_using_vendor({ vendor: "klaviyo" })

"Show me sites with window._fs_org (FullStory) in their inline scripts."

→ boolsai-grep.sites_with_signal({ pattern: "window._fs_org" })

"Find the highest-α tradeable signal in the last 30 days with n ≥ 20."

→ boolsai-signals.find_signals({ horizon_days: 30, min_n: 20 })
