The short answer
77 of the 293 entries in this directory are enterprise only: API access needs a contract, a seat count or a procurement cycle. One more is enterprise leaning. 28 of them ship an official MCP server that a solo operator still cannot reach.
Enterprise gated with no public documentation is the single most useful fact a directory like
this can publish, so it is surfaced rather than hidden. It is also the fact vendors are least happy
to see counted.
Where the gate falls hardest
Counted 2026-08-28. 32 further entries do not publish enough
for the gate to be established at all and are recorded as unknown rather than guessed into a
bucket.
The cruel intersection
28 of these enterprise gated products ship an official MCP server. The protocol
works, the server is real, the vendor built it properly, and the reader of this page cannot call it
without a purchase order. Agent readiness is two questions and this is why they are published as two
columns.

What to do about it
If you are inside a company that already has the contract, the server is a genuine unlock and
worth asking for. If you are one person, build from the
123 solo reachable entries instead
and treat the enterprise tier as something you graduate into rather than something you are blocked
by.

Every number on this page is generated from directory.json at build time and carries
the date it was baked: 2026-08-28. Nothing is typed by hand, nothing is rounded, and nothing is
estimated. The underlying data is published in full. Where the honest
answer is a zero, the zero is printed.
