Company level identification and person level identification are different products with different obligations, and this directory records what the vendor says it does rather than adjudicating either. Check your own jurisdiction and your own privacy notice before wiring any of these into an automated loop. Nothing here is legal advice. ## The numbers, generated at build time | Measure | Count | Of what | |---|---|---| | Entries tagged identify-anonymous-website-visitor | 11 | of 293 directory entries | | Distinct products | 10 | the rest are cross listings | | Official MCP server | 8 | vendor built and maintained | | Community MCP server | 0 | built by somebody else | | No server found | 3 | on the date each entry was checked | | Free to start | 3 | no payment, no sales call | | Solo reachable | 6 | free or paid self serve | | Bench tested | 0 | somebody here actually ran it | ## The ones with an official MCP server - [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... - [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... - [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... - [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... - [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... ## The ones with a free tier - [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... - [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... ## What this list is not It is not a ranking and it is not a recommendation. A job tag means the vendor says the tool does this. Nobody here has run any of them: 0 tools in this directory are bench tested. Two tools on the same list can be wildly different in coverage, price and quality, and this directory does not claim to know which. ## Sources - [The GTM MCP Directory, identify an anonymous website visitor](../jobs/identify-anonymous-website-visitor.md) this site - [The GTM MCP Directory, methodology](../methodology.md) this site - [The GTM MCP Directory, the counted data](../data.md) this site Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-08-25.
