(registered 2025-08-22, last updated 2025-08-22) Scheme Name: mtrust Status: Provisional Contact: Name: Egbert von Frankenberg Organization: Knightfox App Design Ltd. Email: egbert&knightfox.com Specification Document(s): https://github.com/knightfoxapps/mtrust-uri-spec/blob/main/mtrust-uri-specification.txt Scheme Semantics: The `mtrust` URI scheme is designed for trusted communication between ModelTrust Protocol (MTP) clients and servers. It enables resource identification and command signaling within AI Model Proxy Control (MPC) environments. General form: mtrust:///? Example: mtrust://controller.domain.example/task/execute?model_id=xyz123 Encoding Considerations: The scheme uses UTF-8 encoding for the path and query segments, with percent-encoding as specified in RFC 3986 [RFC3986]. Applications/Protocols Using This Scheme: ModelTrust Protocol (MTP) Clients and Servers AI MPC Systems for secured model control and command messaging Interoperability Considerations: Interoperability is ensured within systems implementing MTP; usage outside this scope requires compatible implementation. Security Considerations: The scheme requires strict access control, authentication, and encrypted transport (TLS). Improper use may result in unauthorized access to AI control systems.
