One question, otherwise looks good.

| The [`server.json` schema](schema.json) MAY contain a `repository` property at the root of the JSON object. The `repository` object provides metadata about the MCP server's source code. This enables users and security experts to inspect the code of the MCP service, thereby improving the transparency of what the MCP server is doing at runtime. | ||

Good q - we expect people to create server.json files, but then we want a schema to describe these server.json files. Which is 'the server.json schema', or 'server.schema.json'. So this is correct :)
