RevOps Infra is the most agent reachable category at 22 of 23 entries with a server. Enablement & Coaching is the least at 2 of 14. The pattern is that categories which already sold an API adopted MCP, and categories whose product is a screen did not.

Counted 2026-08-25 from the category blocks in directory.json. Reachable means an official or community MCP server was found on the date the entry was checked.
The categories sold hardest on artificial intelligence are the least usable by anybody else's artificial intelligence. AI SDRs sits at 4 official servers across 23 entries. Enablement & Coaching is at 1 of 14. Meanwhile the plumbing layer, RevOps Infra, is at 22 of 23.
The explanation is commercial rather than technical. If your product is an API, a server is a weekend of work and a new distribution channel. If your product is a seat somebody logs into, a server is a way for customers to stop logging in.
Video Prospecting has 6 community servers against 3 official, the only category in this directory where outsiders built more than the vendors did. Community servers work. They are also maintained by people with no contractual obligation to keep doing it.
Build the agent driven parts of a stack from the top of that table, and expect to write glue or click at the bottom of it. Then apply the second filter, which is the access gate: reachable and purchasable are different columns, and 45 entries need a contract before any of this is relevant.
Every number on this page is generated from directory.json at build time and carries the date it was baked: 2026-08-25. 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.
