Summary
Draft Go reference implementation for SEP-2127 MCP Server Cards.
This adds an experimental
mcp/experimental/servercardpackage that ports the server-side convenience helper from modelcontextprotocol/python-sdk#2951 for building a static Server Card frommcp.Implementationmetadata and serving it with the discovery CORS/cache headers.Tracking / coordination
guglielmoc/SEP-2133_extensions_frameworkThis is opened as a draft because it is a nontrivial experimental API and should be promoted after WG review / proposal soak.
Validation
go vet ./...go build ./...go test ./...Adds strong ETag generation plus If-None-Match conditional-request handling for Server Cards; see Discovery: recommend ETag + conditional requests (If-None-Match/304) as a SHOULD for card/catalog endpoints experimental-ext-server-card#33.
