Counted 2026-08-25. Domain to company is the most common single call in a GTM agent's loop, because a domain is the one identifier that arrives from everywhere: a form fill, an email address, a news item, a website visit. It is also the most widely tagged job in this directory's enrichment family. ## The numbers, generated at build time | Measure | Count | Of what | |---|---|---| | Entries tagged enrich-company-from-domain | 34 | of 293 directory entries | | Distinct products | 31 | the rest are cross listings | | Official MCP server | 26 | vendor built and maintained | | Community MCP server | 2 | built by somebody else | | No server found | 6 | on the date each entry was checked | | Free to start | 12 | no payment, no sales call | | Solo reachable | 21 | free or paid self serve | | Bench tested | 0 | somebody here actually ran it | ## The ones with an official MCP server - [Cargo](../tools/cargo.md) Official MCP · Free to start A GTM/RevOps engineering platform (YC S23) that lets revenue teams define, version, and automate go-to-market logic - lead sourcing, enrichment,... - [Diffbot](../tools/diffbot.md) Official MCP · Free to start A web-extraction and "Knowledge Graph" company that crawls the public web and structures it into an entity graph (organizations, people, articles)... - [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... - [LeadMagic](../tools/leadmagic.md) Official MCP · Free to start A B2B contact/company data API and CLI that finds and validates work emails, mobile numbers, and social-to-email matches, plus... - [Lusha](../tools/lusha.md) Official MCP · Free to start A B2B contact and company database (300M+ profiles) accessed via a browser extension, web prospecting platform, and bulk CSV/API enrichment for... - [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... - [Prospeo](../tools/prospeo.md) Official MCP · Free to start A B2B contact database/lookup tool that finds verified work emails and mobile phone numbers for a given person or domain and returns basic... - [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... - [ZoomInfo](../tools/zoominfo.md) Official MCP · Free to start A B2B contact/company database and go-to-market platform (500M+ contacts, 100M+ companies) built from web crawling, public filings, and human... - [Apollo.io](../tools/apollo-io.md) Official MCP · Paid, self-serve A combined B2B contact database (265M+ contacts) and sales engagement platform in one product - prospect search/filtering, email and call sequencing,... - [Clay](../tools/clay.md) Official MCP · Paid, self-serve A spreadsheet-style workflow/orchestration tool that runs lead and company records through "waterfall" lookups across 100-200+ third-party data... - [Coresignal](../tools/coresignal.md) Official MCP · Paid, self-serve Sells structured B2B datasets and APIs (company, employee/people, job-posting records) scraped and normalized from public and professional-network... 11 more are on the linked page.

The cut is the display limit, not a ranking. ## 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, enrich a company from a domain](../jobs/enrich-company-from-domain.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.
