Reading the open index

519 slips. Each row is a pointer: origin, the command that loads it, the subscription if there is one. We do not warehouse the trees. Install counts are editorial. This page is the anatomy of the catalog, derived at render from the same listing file the market board uses.

Filter on the market board. A harness is a worker. A skill is a package the worker knows how to load. An advance is the layer that makes a thousand workers cheaper or safer. MCP is a tool server. Do not rank them on one axis.

Open means the runtime is free to fetch. Seat, usage, and enterprise are the bill. Community-tier cannot load on a fleet with prodOnlySigned. That last line is the security product.
