SentinelGate

SentinelGate is an open-source MCP (Model Context Protocol) server that serves as a proxy and policy decision point for controlling AI agent access to system tools via deterministic rules. It enables fine-grained access control, RBAC (Role-Based Access Control), and full audit trails for every AI-initiated action (tool calls, shell commands, file access) before execution. Integrating with container and sandbox orchestration platforms (Docker, Kubernetes, Firecracker, Podman, Modal, Fly.io, systemd, LXC/LXD, Daytona, AWS ECS/Fargate), SentinelGate is designed for developers and DevOps teams running self-hosted AI agents who need to enforce security, policy, and auditing for sensitive system interactions.
