- Make description required to match server.json schema - Make capabilities optional to avoid breaking existing server.json files - Remove MCP Resource endpoint (mcp://server-card.json) — discovery should happen pre-connection via .well-known, not post-connection - Remove registry endpoint section — registry already serves server.json - Clarify that local/stdio servers use server.json + Registry path Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

description→ required: Matches the existingserver.jsonschema wheredescriptionis in therequiredarray. Avoids an unnecessary divergence.capabilities→ optional: Sinceserver.jsonis being redefined in terms of the Server Card shape, makingcapabilitiesrequired would break all existingserver.jsonfiles that don't have it. Optional keeps the superset relationship clean.mcp://server-card.jsonresource requires an established MCP connection, which defeats the purpose of pre-connection discovery. Removed in favor of focusing on.well-knownfor remote servers.server.json— no need to spec a separate mechanism here.server.json+ the MCP Registry rather than Server Cards.
