Toward Composition-Aware Operational Assurance for MCP: Observable Control Gaps, Outcome-Evidence Classes, and a Status-Bounded Design-Science Case

Composable Model Context Protocol (MCP) workflows require assurance beyond endpoint reachability. This position and design-science preprint defines observable objects and bounded closure conditions for three related problems: the Registry-Runtime Gap, pre-execution and runtime Co...

Measurement Drift During the MCP 2026 Transition: Two Revision-Aware Audit Waves of Publicly Discovered Endpoint URLs

Measuring protocol migration while the measurement instrument is itself changing creates a risk of mistaking instrument coverage for ecosystem change. This preprint reports two revision-aware audit waves derived from a frozen, append-only Model Context Protocol (MCP) observation...
