> **RESEARCHED** Facts from public sources with URLs. No usage claims. Nobody has run this tool. The other tier is BENCH-TESTED, which means Andrew personally ran the tool on a stated date and cannot be bought at any price. Across the whole directory that count is 1.

Vendor: [zoominfo.com](https://zoominfo.com) · entry id 01-zoominfo · source 01-data-enrichment.md line 7

**What it does**
A B2B contact/company database and go-to-market platform (500M+ contacts, 100M+ companies) built from web crawling, public filings, and human researchers, used for prospecting, account research, and lead enrichment.

**AI features, separated from automation with an AI label on it**
ML is used for record matching/deduplication and lead scoring; "Copilot" is an AI assistant that summarizes accounts, prioritizes leads, and drafts outreach emails on top of the database. The core value (the data itself) is not AI-generated - the AI layer is a research/writing assistant bolted onto a traditional data product.

**RevOps role**
Upstream contact/company data source feeding CRM, enrichment, and outbound tooling; typically the "system of record" for firmographic/contact data in larger RevOps stacks

**MCP server**

- **Status bucket**: Official MCP

- **Auth**: OAuth for user-level access, or client credentials for service accounts; no API keys stored by the client. A local mcp-remote bridge is used for stdio clients.

- **Parsed URLs**: 3 found in the mcp_url field

- **Endpoint probe**: answered, asking for a key
- **Endpoint URL**: [https://mcp.zoominfo.com/mcp](https://mcp.zoominfo.com/mcp)
- **Probed**: 2026-09-04, HTTP 401

The vendor ships and maintains the server itself. A wrapper built by Zapier, Composio or a similar third party does not count as official. The status was established by hand on 2026-09-03. On 2026-09-04 the recorded URL answered an MCP initialize as a server, which is liveness and nothing more: nobody has run its tools.

**Access gate**

- **Gate bucket**: Free to start

- **Can a solo operator reach it**: Yes, without talking to anyone

api_gate, verbatim from the file:

free (CHANGED 2026-08-25, see notes - the MCP/API path is now self-serve via GTM.AI; the classic seat-based ZoomInfo platform remains enterprise-only)

**API documentation**

[https://gtm.ai/docs](https://gtm.ai/docs)

No documentation text is reproduced anywhere on this site. Read the vendor page for the prose. The structured docs digest specced in SPEC section 3 has not been built or crawled: docs_digest is null on every entry in this build.

**GitHub health**

Not measured. github_url, github_stars, github_last_commit and github_archived are null on every entry in this build.

The refresh rail specced in SPEC section 7.2 has not been run. An unstamped star count is a lie, so nothing is shown rather than something stale.

A github.com URL already appears somewhere in this entry, which is a seed for that rail and not a measurement of repo health:

- [https://github.com/Zoominfo/zoominfo-mcp-plugin](https://github.com/Zoominfo/zoominfo-mcp-plugin)

**On GitHub**

[github.com/Zoominfo](https://github.com/Zoominfo) tied to the vendor by rule 1, account website https://www.zoominfo.com has the vendor's domain, confidence strong

- **Public repositories**: 8, forks excluded, as read on 2026-09-08
- **Mention MCP**: 1 of them
- **Look like CLIs**: 1 of them
- **Latest push**: 2026-09-03

The five most recently pushed, on 2026-09-08:

| Repository | Kind | Description | Stars | Pushed | Latest release |

| [gtm-ai-cli](https://github.com/Zoominfo/gtm-ai-cli) | CLI | A command-line tool for searching ZoomInfo's go-to-market data | 1 | 2026-08-30 | v1.1.0 |
| [homebrew-gtm-ai](https://github.com/Zoominfo/homebrew-gtm-ai) | infrastructure | Homebrew tap for gtm-ai formulae | 0 | 2026-08-26 | |

Kind is a heuristic guessed from the repository name, topics and description, not a fact the vendor stated. A repository count is activity, not a verdict. Read 2026-09-08.

**Jobs it can do**

- [Search people by criteria](../jobs/search-people-by-criteria.md)
- [Search companies by firmographics](../jobs/search-companies-by-firmographics.md)
- [Enrich a company from a domain](../jobs/enrich-company-from-domain.md)
- [Find a person's LinkedIn URL from a name and company](../jobs/find-linkedin-url-from-name-and-company.md)
- [Find a work email address](../jobs/find-work-email.md)
- [Find a phone number](../jobs/find-phone-number.md)
- [Research an account before a call](../jobs/research-account-for-call-prep.md)
- [Draft personalized outreach](../jobs/draft-personalized-outreach.md)
- [Score and prioritize leads](../jobs/score-and-prioritize-leads.md)

A job tag means the vendor says the tool does this. It is not a test result, not proof the capability is reachable through the tool's MCP server, and not proof it is available on the gate this entry records.

Tagged by machine-pass on 2026-08-25 against the closed 56 job vocabulary. 271 of 1,252 entries carry at least one tag; 849 tags are assigned in total.

**Notes, verbatim from the file**
MATERIAL CHANGE FOUND 2026-08-25, and it contradicts this directory's own headline finding that legacy incumbents are enterprise-gated. ZoomInfo launched GTM.AI (gtm.ai), a "headless GTM context layer," announced 2026-06-01, plus a GTM.AI CLI. The published pricing page states "one tier, no contract, no seat fees," 1,000 data credits plus 1,000 AI credits free to start with no credit card, then pay-as-you-go from a $20 minimum top-up at $0.10 per data credit (launch promo; $0.35 regular) and $0.05 per AI credit, charged once per record per year. Search, lookup, find-similar and GTM-context tools are documented as free to call; credits are consumed only on enrichment and AI research. The server card declares 22 tools (account_research, browse_audiences, browse_engagements, contact_research, conversation_intelligence, enrich_companies, enrich_company_signals, enrich_contacts, enrich_intent, enrich_news, enrich_scoops, find_recommended_contacts, find_similar_companies, find_similar_contacts, get_audience, gtm_context, lookup, search_companies, search_contacts, search_intent, search_scoops, update_gtm_context) at server version 3.0 over HTTP. gtm.ai also publishes /.well-known/agent-skills/index.json and /.well-known/api-catalog, which is the most agent-native discovery surface found anywhere in this directory. PRIOR STATE, kept on the record: as of 2026-08-24 this entry read api_gate enterprise-only, on the basis that no self-serve path existed and API access shipped inside annual contracts reportedly starting around $50K/year. That classic seat-based platform motion still exists; what changed is that a credit-metered self-serve door opened next to it. NOT VERIFIED THIS PASS: whether the free GTM.AI tier's data coverage matches a paid ZoomInfo seat, and whether "ZoomInfo Lite" (named in secondary sources as the permanent free tier) is the same thing as the GTM.AI free tier or a separate product. Both need a hands-on check before this is used on camera. 2026-09-03: vendor docs state the GTM.AI MCP tool Enrich Contacts accepts "a name paired with company context, an email address, or a ZoomInfo contact ID" and returns a LinkedIn URL among its fields, subject to package entitlements (https://gtm.ai/content/docs/mcp/tools/enrich-contacts.md); the docs state one bulk data credit per new contact, with re-enrichment within 12 months free.
