Signals are the trigger layer: the thing that starts an agent's loop rather than something it calls halfway through. Coverage here is decent and the access gate is the harder problem. Tools that try to answer "who is about to buy, and how do you know." The category splits cleanly into two eras: the legacy enterprise intent-data incumbents (6sense, Demandbase, Bombora, HG Insights) sold on annual contracts with no self-serve path, and a newer wave of visitor-ID/job-change/ API-first tools (RB2B, Warmly, Crustdata, TheirStack, PredictLeads) built for solo operators with free tiers and documented MCP servers. ## The ones an agent can call - [Leadfeeder (product line rebranded/merged under Dealfront; dealfront.com redirects to leadfeeder.com)](../tools/leadfeeder.md) Official MCP · Free to start Identifies companies visiting a website via IP-to-company matching, tracks page-level visit behavior, and surfaces intent signals plus verified... - [PredictLeads](../tools/predictleads.md) Official MCP · Free to start Aggregates five signal categories (job openings, technology detections, news events, business connections, firmographics) across 129M companies in... - [TheirStack](../tools/theirstack.md) Official MCP · Free to start Tracks 233M+ job postings across 195+ countries and 33,000+ technologies to detect hiring signals, technographic footprint, and buying-intent signals... - [Warmly (Warmly.ai)](../tools/warmly.md) Official MCP · Free to start De-anonymizes website visitors at the person and company level from site traffic, and aggregates first-party (web/product/CRM), second-party... - [Crustdata](../tools/crustdata.md) Official MCP · Gate unknown A real-time API for company and person firmographic/growth data (headcount trends, funding, tech stack, web traffic, social signals), positioned as... - [Factors.ai](../tools/factors-ai.md) Official MCP · Paid, self-serve De-anonymizes website visitors and tracks named-account behavior (page visits, LinkedIn/Google ad engagement, email/content engagement, third-party... - [RB2B](../tools/rb2b.md) Official MCP · Paid, self-serve Deanonymizes B2B website traffic by matching visitor IP/device identifiers and first/third-party data against a contact database to reveal the... - [Snitcher](../tools/snitcher.md) Official MCP · Paid, self-serve Identifies anonymous website visitor companies via IP-to-company database matching, tracks on-site behavior (pages viewed, session length, return... - [Sumble](../tools/sumble.md) Official MCP · Paid, self-serve Builds an account-intelligence knowledge graph by continuously scanning tens of millions of public sources (job boards, company sites, social media,... - [6sense](../tools/6sense.md) Official MCP · Enterprise only Detects B2B buying intent by combining IP-based website deanonymization, a proprietary third-party intent/content-consumption network... - [Common Room](../tools/common-room.md) Official MCP · Enterprise only Aggregates buyer/community engagement signals - Slack, Discord, GitHub activity (stars, PRs, issues), product usage, and third-party intent data... - [Crossbeam](../tools/crossbeam.md) Official MCP · Enterprise only Compares your account list against your partners' account lists to surface overlaps, partner-shared contacts, and warm introduction paths for... - [Demandbase (Demandbase One)](../tools/demandbase.md) Official MCP · Enterprise only Identifies and scores in-market B2B accounts by combining IP/website deanonymization, a global firmographic/technographic database, and intent-signal... - [G2 Buyer Intent](../tools/g2-buyer-intent.md) Official MCP · Enterprise only Surfaces which companies are researching your product and your competitors on G2's review marketplace, plus the review and category data behind those... - [HG Insights (Phoenix platform)](../tools/hg-insights.md) Official MCP · Enterprise only Aggregates B2B technographic data (software/tech a company runs, sourced from job postings, web crawling, public filings, partner feeds),... - [Similarweb](../tools/similarweb.md) Official MCP · Enterprise only Web, app and market intelligence platform that estimates traffic, audience, keyword and competitive metrics for any domain, used in sales as an... - [UserGems](../tools/usergems.md) Official MCP · Enterprise only Tracks job changes of known contacts (past customers/champions moving to new companies) plus 30+ other native signals (new hires, promotions,... - [Trigify (Trigify.io)](../tools/trigify.md) Community MCP · Paid, self-serve Monitors LinkedIn, X/Twitter, Reddit, YouTube, and podcasts for keyword mentions and engagement (likes, comments, shares, job changes), mapping who... ## The rest of the category 10 entries here had no server found, or the check could not settle it.
