ZoomInfo

A live handshake means the URL answered an MCP initialize as a server on the probe date. It is liveness and nothing more: nobody has run its tools. A tool being catalogued means a server names it, by answering tools/list, in its own source, or in the vendor's documentation. None of them has been called. A tool count of 0 means not measured, never zero tools.

12 distinct job labels, the union across 2 products, tagged 2026-08-25. 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.

• https://mcp.zoominfo.com/mcp (ZoomInfo, endpoint, probed 2026-09-04)
• https://github.com/opensourceops/chorus-mcp-server (Chorus, docs page, probed 2026-09-04)

An endpoint is where an agent connects. A docs page is where a person reads about connecting. Both are published because both are what the probe found; an agent needs the first.

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.

A job tag is a vendor claim: it means the vendor says the product does this, and it is not a test result. A listed tool has not been run: the catalogue says what an agent could try, not what works. 1 of 1,252 directory entries are bench tested, meaning somebody personally ran the tool on a stated date, and 0 of this vendor's 2 products are among them. There is no verdict here on whether this vendor is better than another.

Vendor pages group the directory's canonical product entries by vendor_domain. The vendor name is the product display name that matches the domain when several products share it; nothing on this page is typed by hand. Data baked 2026-09-27 by build_directory.py (phase 1).
