Model Context Protocol releases new spec, launches server audit tool

The Model Context Protocol (MCP) has released its 2026-07-28 specification, introducing a stateless request lifecycle. The accompanying mcpscore tool provides a one-command audit for MCP servers, generating a quality score out of 100 based on 72 deterministic rules covering protocol adherence, tool quality, security, and readiness for the new spec. This tool now supports auditing authenticated servers via OAuth 2.0 tokens and offers partial audits for unauthenticated servers, ensuring that sensitive tokens are not logged. AI

IMPACT Enhances the reliability and security of AI model context protocols through automated auditing.

RANK_REASON The cluster describes a new tool for auditing servers adhering to a specific protocol.
