Sentinel-Gate: Access Control for AI Agents

MCP proxy and Policy Decision Point for AI agent access control, supporting CEL policies and RBAC.

Sentinel-Gate: AI Agent Access Control

Sentinel-Gate provides robust access control for AI agents, acting as an MCP proxy and Policy Decision Point (PDP). This tool is designed for developers building and deploying AI agents, offering a centralized mechanism to manage and enforce access policies. By integrating Sentinel-Gate, you can ensure that your AI agents interact with resources and other agents according to predefined rules, enhancing security and operational integrity.

What Sentinel-Gate Does

Sentinel-Gate intercepts requests directed at AI agents and evaluates them against configured policies. It functions as a gatekeeper, determining whether an incoming request should be allowed or denied. This is achieved through its role as an MCP (Message Communication Protocol) proxy, which sits between the client and the AI agent. The core of its functionality lies in its Policy Decision Point (PDP) capabilities, where it consults policy definitions to make authorization decisions.

Key Features

MCP Proxy: Acts as an intermediary for AI agent communication, enabling policy enforcement at the network level.
Policy Decision Point (PDP): Evaluates access requests based on defined policies.
CEL Policies: Supports Common Expression Language (CEL) for flexible and powerful policy definition. This allows for complex conditions and dynamic policy evaluation.
RBAC Support: Integrates Role-Based Access Control (RBAC) to manage permissions based on user or agent roles.
Source: Available on GitHub, promoting transparency and community contribution.

Who Sentinel-Gate is For

Sentinel-Gate is an essential tool for AI developers , ML engineers , and system architects who are responsible for the security and management of AI agent deployments. It is particularly useful for projects involving multiple AI agents, sensitive data, or regulated environments where strict access control is paramount. If you are building complex AI systems, managing distributed agents, or need to implement granular permissions for AI interactions, Sentinel-Gate offers a technical solution to enforce your security posture.
