Overview

AI-generated overview

Lets an assistant query quant-research signals derived from public-company website technology stack changes, benchmarked against SPY.

What you can do
Boolsai Signals is a remote MCP server for quant research on tradeable signals found in website stack changes across 316 public companies, covering 1,761 events. Its seven tools include universe_summary, find_signals, test_filter, recent_events, event_dossier, scan_at_date and ticker_history. It draws on a historical scan corpus with Wayback Machine integration, and its methodology is described in the initialize response.
When to use it
Use it when an assistant needs to explore whether changes in a public company's website technology stack line up with tradeable signals, review recent events, or inspect a specific company's history. It suits research and screening rather than live trading.
Requirements
A remote streamable HTTP endpoint at signals.boolsai.ai; no package install. The provider states no authentication, API key, environment variables or headers are required. Network access to the endpoint is needed.
Before you install
The server presents itself as no-auth and read-only, so no credentials are requested. Signals are research output, not investment advice, and the provider's own benchmark and methodology claims are unverified here. Confirm the data's freshness and licensing before relying on it for decisions.

Installation

In SourceWeft

  1. Open Boolsai Signals in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.boolsai%2Fsignals/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

Boolsai — MCP server suite

[MCP] [License: MIT] [No-auth]

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

ServerConnect URLToolsWhat it does
Boolsai Scanhttps://boolsai.ai/mcpboolsai_scan, boolsai_scan_pathsLive 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 Directoryhttps://directory.boolsai.ai/mcpsummary, site_dossier, sites_using_vendor, lookup_id, brands_in_city, brands_in_market, stack_archetype, compare_sites, similar_sites, brands_by_founderPre-indexed directory of tens of thousands of ecommerce sites by vendor, account ID, country, founder, city, archetype.
Boolsai Grephttps://grep.boolsai.ai/mcpgrep_pattern, count_pattern, sites_with_signal, list_signal_typesParallel 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 Signalshttps://signals.boolsai.ai/mcpuniverse_summary, find_signals, test_filter, recent_events, event_dossier, scan_at_date, ticker_historyQuant-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).

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 })

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 daysRequired25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declaredRequired10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts
