mcp-hangar vs toolhive
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.; toolhive: ToolHive simplifies and secures the deployment of Model Context Protocol (MCP) servers, offering a comprehensive solution for managing AI toolchains in production. It provides a modular architecture with a Gateway, Registry Server, Runtime, and Portal for instant, secure, and scalable operations across various environments.

Preventing unauthorized or malicious changes to LLM tool descriptions and behavior.

When to choose:
- You want MCP servers to run in isolated containers with scoped permissions and managed secrets, on Docker, Podman or Kubernetes.
- You want the same tooling from a laptop (desktop app or CLI) to a Kubernetes Operator.
- Your team needs a registry with provenance verification, an SSO-capable gateway and audit logging.
When to skip:
- You just want to run one MCP server: it needs Docker, Podman or Kubernetes and is heavier than starting the server directly.
- You want a single component: the Runtime, Registry, Gateway and Portal take time to understand, and parts live in separate repositories.
- You expect container isolation to replace reviewing what each server can reach.
