Overview
Agent Guard delivers secure secret retrieval and observability for AI agent communications by reducing the risks of unmonitored access and hardcoded secrets. Designed for environments using STDIO communication, it helps keep secrets ephemeral, centrally managed, and out of code. By auditing all interactions and integrating with AWS Secrets Manager or CyberArk Secrets Manager (previously CyberArk Conjur), Agent Guard provides dynamic, just-in-time secret injection, empowering organizations to meet high standards of compliance, traceability, and operational security without compromising performance or flexibility.
Usage instructions:
- github.com/cyberark/agent-guard/blob/main/docs/agent-guard-containerized.md
Key capabilities and differentiators:
- Auditing and monitoring: Interactions between the AI agent and MCP servers are logged, providing complete traceability and compliance with enterprise security standards.
- STDIO-based deployment support: Ideal for local or containerized environments, the proxy supports STDIO communication while isolating the MCP server from direct access to sensitive data on the host.
- Dynamic secret injection: Secrets are ephemeral, so they are not stored in code or local files. Instead, they are dynamically retrieved from your secrets manager (AWS Secrets Manager or CyberArk Secrets Manager), injected into the MCP server session, and disposed of after use.
- Lightweight and flexible: Easy to deploy and integrate into existing AI workflows without introducing significant overhead.
Integration with AWS:
- Agent Guard is configurable with the Amazon Q Developer agent to trace and audit interactions with MCP servers using Agent Guard MCP proxy capability. It can be used for securely retrieving secrets required by the AWS Q Developer agent and its tools. Those secrets can be retrieved from AWS Secrets Manager or CyberArk Secrets Manager.
- Optional integration with AWS CloudWatch: Centralized logging and monitoring for enhanced observability.
- IAM Role support: Allows only authorized agents to access specific secrets or perform actions.
Please note: this offering is offered free-of-charge and is therefore subject to section 1.4 of the CyberArk SaaS Terms of Use.

Container image
Containers are lightweight, portable execution environments that wrap server application software in a filesystem that includes everything it needs to run. Container applications run on supported container runtimes and orchestration services, such as Amazon Elastic Container Service (Amazon ECS) or Amazon Elastic Kubernetes Service (Amazon EKS). Both eliminate the need for you to install and operate your own container orchestration software by managing and scheduling containers on a scalable cluster of virtual machines.
