  "_note": "SPECULATIVE PATH. As of the 2026-07-28 specification, .well-known is standardised only for OAuth authorization discovery (SEP-2351). Capability discovery itself is neither speculative nor optional: the server/discover RPC is mandatory for every 2026-07-28 server, and this server answers it through the mcp gem rather than through this file. What remains unmerged is serving that description at a .well-known PATH -- /.well-known/mcp/server-card.json (SEP-1649) and /.well-known/mcp (SEP-1960) are on the published roadmap only, and the field shapes below are a best reading of those proposals rather than a validated schema. Served because it is a static file and costs nothing; do not treat its presence as spec compliance. The authoritative machine-readable description of this server is tools/list over the endpoint itself."
