martin-loop vs toolhive-registry-server

martin-loop: MartinLoop is a governance layer for AI coding loops that enforces budget caps, verifier gates, rollback evidence, and audit trails. It prevents unbounded retries by stopping unsafe or uneconomical work before execution, providing visibility and accountability for autonomous coding agents.; toolhive-registry-server: The ToolHive Registry Server implements the official MCP Registry API specification, serving as the centralized metadata engine for the ToolHive platform. It enables enterprises to curate, discover, and govern MCP servers with security and auditability built-in, aggregating multiple sources into a unified catalog.
