Q: Which is better, mcp-hangar or agents-shipgate?

By GitHub stars, agents-shipgate 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.; 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.
