+- Packaged in with the source code of an MCP server, so as to have a structured way to identify a server given just its source code
 
 All of these scenarios (and more) would benefit from an agreed-upon, standardized format that makes it easy to port around and maintain a consistent experience for consumers and developers working with the data. At the end of the day, it's all the same data (or a subset of it). MCP server maintainers should have to manage one copy of this file, and all these use cases can serve that file (or a programmatic derivative/subset of it).
