JanuScope vs mcp-hangar

JanuScope: JanuScope is a local proxy that wraps any Model Context Protocol (MCP) server, enhancing AI tool usage with critical security features. It enforces policies, redacts sensitive data, audits all calls, and pre-injects database schemas to improve LLM accuracy and safety.; mcp-hangar: MCP Hangar is a self-hosted policy enforcement plane for your MCP server fleet, providing deterministic admission and egress policies, attributable audit, and SIEM export. It ensures tool integrity by enforcing tool-schema digest pinning, preventing unauthorized changes to tool descriptions.
