Spec 2026-07-28 readiness

NOT OBSERVABLE

Not determinable from the public probe. Credential-gated endpoints do not complete an unauthenticated handshake, so the negotiated revision cannot be read. This is a coverage limit, not a finding.

3 of 6 signals evaluable on the public probe · deprecation windows close 2027-07-28
  • RDY-01Transport generationcurrent
    Streamable HTTP: the transport the 2026-07-28 stateless core is built on.
  • RDY-02Protocol revisionn/a
    Revision negotiation could not be observed.
  • RDY-03Stateless corecurrent
    Operates without a session header, matching the 2026-07-28 stateless core.
  • RDY-04Client registrationcurrent
    Advertises Client ID Metadata Document support, the 2026-07-28 replacement for Dynamic Client Registration.
  • RDY-05Cacheable tool catalogn/a
    Tool catalog cache posture not observable.
  • RDY-06Deprecated capabilitiesn/a
    Capability set not observable.

Readiness measures migration posture against the specification finalized 2026-07-28. It is reported separately because a well-authenticated server on deprecated transport is a migration risk, not a security defect — scoring both on one axis would misprice both. Signals that could not be evaluated are excluded from the score rather than counted as passing.

CFM-01AuthenticationPASS
Endpoint refuses unauthenticated MCP initialize.
CFM-02Authorization (OAuth)PASS
401 challenge with WWW-Authenticate and RFC 9728 protected-resource metadata: spec-conformant OAuth discovery.
CFM-03Tool poisoningN/A
Tool surface is behind authentication: requires the authenticated battery (Cleared-to-Connect).
CFM-04Scopes & least privilegeN/A
Tool surface is behind authentication: requires the authenticated battery (Cleared-to-Connect).
CFM-05Secrets exposureN/A
Server metadata is behind authentication: requires the authenticated battery (Cleared-to-Connect).
CFM-06Destructive-tool guardrailsN/A
Tool surface is behind authentication: requires the authenticated battery (Cleared-to-Connect).
CFM-08Transport securityPASS
TLS transport.
CFM-10Exposed configuration surfacePASS
No configuration or credential documents served at well-known paths.
CFM-09Command-injection exposure (advisory)INFO
Tool surface is behind authentication: the command-execution sink surface is not publicly visible. STDIO config-injection hardening (OX Security, 2026-04-15) is attested via Cleared-to-Connect, not remotely tested.
