This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- McpServer initializes with server metadata and exposes the underlying low-level Server instance
- McpServer.tool registers tools with Zod schema validation and executes handlers over transport
- McpServer.tool returns structured error results with isError true when argument validation fails
- McpServer.resource registers static and dynamic templated resources and serves resource contents
- McpServer.prompt registers prompt templates with arguments and renders structured prompt messages
- McpServer pairs with Client over InMemoryTransport and closes cleanly
