heddle vs agents-shipgate

heddle: Heddle provides a policy-and-trust layer for Model Context Protocol (MCP) tool servers, enabling secure and declarative exposure of APIs as AI agent tools. It offers built-in security features such as trust enforcement, credential brokering, and tamper-evident audit logging, alongside containerized sandboxing and AI-powered configuration generation.; agents-shipgate: Agents Shipgate is an open-source CLI and GitHub Action that serves as a deterministic merge gate for AI-generated agent capability changes. It performs local-first, static Tool-Use Readiness review, scanning various agent artifacts to ensure explicit approval policies, scope coverage, and idempotency evidence before merging.
