mcp-hangar vs helm-ai-kernel

Q: Which is better, mcp-hangar or helm-ai-kernel?

By GitHub stars, helm-ai-kernel has more community adoption, but the best choice depends on your specific use case.

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.; helm-ai-kernel: HELM AI Kernel acts as a fail-closed execution firewall, intercepting AI agent requests to enforce default-deny policies and quarantine unknown tools. It provides verifiable evidence through signed receipts and EvidencePacks for audit and tamper checks, ensuring secure and governed AI operations.
