Spec 2026-07-28 readiness
Verdict: at-risk(requires the removed Mcp-Session-Id session mechanism).

| Accepts handshake-free calls | no |
| server/discover implemented | no |
| Session independence | session required |
| Routing headers enforced | ignored |
Advisory: no resultType on results; no cache metadata on list results; negotiates 2025-06-18.
