Separately from the zero official list, some jobs are barely covered by any tool at all. These are the ones where the vocabulary describes something real and the market has almost nothing tagged against it.
Because a gap is the most actionable thing in a directory. If you were going to write an MCP server for something, the top of the first table is where an agent builder is currently stuck with no vendor maintained option, and the second table is where the market itself is thin.
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.
