Access control for AI agents. MCP proxy + Policy Decision Point. CEL policies, RBAC, full audit trail. Any container, any sandbox.

SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.

    Policy definitions are readable and auditable, not opaque config.

    CEL policy-based access control for AI agents is the right approach to agent governance.

    Good for organizations that need fine-grained control over what agents can access.
