Add transport information to MCP server listings #219
Description
Currently, MCP server images in the Docker MCP registry don’t indicate which transport(s) they expose/require (e.g., stdio, sse, streamableHTTP). Since some MCP clients need a specific transport to connect, this lack of information makes integration harder. Developers often have to experiment or read the source to figure out compatibility.
- Add a field to the MCP registry metadata (or include in the Docker Hub listing) that specifies which transports the server supports.
