Sentinelgate vs toolhive-registry-server

Sentinelgate: SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.; 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.
