Four Layers of Security for MCP Containers
The following protective measures are recommended for the security risks of containerized deployments:
- Permission Control:compulsory use
--security-opt=no-new-privilegesparameter to disable the--privilegedHigh-risk options such as - Key management:pass (a bill or inspection etc)
-eparameter dynamically injects the API key (e.g.-e NOTION_API_KEY=your_key), avoid hard-coding in the mirror - Network isolation:Using Docker Network Isolation (
--network) or Kubernetes NetworkPolicy restricts inter-container communication - Mirror Image Verification:pass (a bill or inspection etc)
docker scanCheck for image vulnerabilities and prioritize the use of officially verifiedghcr.io/metorialroot
Advanced solution: configure SecurityContext and PodSecurityPolicy in Kubernetes, and enterprise users can consider using Vault for key rotation.
