Tools and MCPs
What a tool is to the model, what a server adds, and when neither is the right shape. A tool exists as a name, a description and a schema, so most failures traced in these items are failures of that surface rather than of the code behind it. A server earns its transport and its authentication only where several independent consumers need the same access. The last objective is a sorting exercise, since skills, servers, built-in capability and subagents each answer a different complaint.

Drilling one domain tells you about one domain. A full-length timed mock in blueprint proportions is what produces a score you can read.
