Please add mcpCard property, it's important for the validation

It doesn't exist in the official spec, so we can't easily add it as mandatory without becoming incompatible.
This is something we should bring up in the official discussion, probably here: modelcontextprotocol/modelcontextprotocol#2152
The $schema could be used for this, too - but so far we don't have a standardized URL for this. Also versions in the $schema could change, so the validator function to determine the document type probably needs some startsWith() condition

Proposal is to extend the MCP registry server.schema.json to support the requirement for mcp-server-card.
The idea is to not have two different formats to describe MCP Servers, instead the server.json can be extended to cover for both scenarios (publishing to MCP Registries and describing Remote MCP Servers in one card file).
YAML format to support comments with TODOs for open discussion points.
