Zero Trust for AI - Securing MCP Servers-1](https://solutions.cerbos.dev/hs-fs/hubfs/eBook%20-%20Zero%20Trust%20for%20AI%20-%20Securing%20MCP%20Servers-1.png?width=1425&height=1848&name=eBook%20-%20Zero%20Trust%20for%20AI%20-%20Securing%20MCP%20Servers-1.png "eBook - Zero Trust for AI - Securing MCP Servers-1") # Zero Trust for AI: Securing MCP Servers MCP servers are now among the most privileged components in your AI stack.  They represent a fundamental new risk that traditional security controls weren't designed to address, requiring immediate attention from security, compliance, and risk management teams. This ebook provides a practical blueprint for securing MCP servers using externalized, fine-grained authorization. Download the ebook ## **What's inside the ebook** Drawing from customer implementations, security architect discussions, and emerging MCP security research, we cover: - ## Strategic risk considerations How MCP servers fit into your broader risk management and compliance framework, and what security leaders need to know. - ## Implementation frameworks Authorization policies and deployment patterns to transform your MCP server from a “confused deputy” into a governed, trusted co-pilot. - ## Externalized authorization architecture The PEP/PDP pattern that decouples policy enforcement from policy decisions, enabling Zero Trust for AI systems. ![Frame 2147215472-2](https://solutions.cerbos.dev/hs-fs/hubfs/Frame%202147215472-2.png?width=328&height=328&name=Frame%202147215472-2.png "Frame 2147215472-2") Download the ebook ## Created for IAM, security and engineering team ## Strategic guidance for enterprise risk management ## Proven frameworks and deployment patterns ## 50+ pages of in depth content ## **Zero Trust architecture to prevent MCP servers from becoming your biggest liability** ![Your MCP server is the new high privilege account](https://solutions.cerbos.dev/hs-fs/hubfs/Screenshot%202025-09-25%20at%202.22.27%20PM.png?width=732&height=953&name=Screenshot%202025-09-25%20at%202.22.27%20PM.png "Your MCP server is the new high privilege account") ## Your MCP server is the new high privilege account We establish why MCP servers represent a fundamental shift in enterprise security architecture. You will learn how changes in identity workflows create new considerations for risk management teams and what this means for your organization's security posture. Topics covered: Broken identity chains, high risk workflow anatomy, streaming state complexity, privilege concentration, transaction tokens. ## Why traditional roles fail in a dynamic world We examine the critical flaws of Role-Based Access Control when applied to AI agents. You will see the pattern of role explosion, understand context blindness as RBAC's fatal flaw, and learn why teams resort to dangerous admin role bypasses. Topics covered:Role explosion patterns, context-aware authorization requirements, hard coded logic antipatterns, principle of least privilege violations. ![Why traditional roles fail in a dynamic world](https://solutions.cerbos.dev/hs-fs/hubfs/Screenshot%202025-09-25%20at%202.24.29%20PM.png?width=734&height=949&name=Screenshot%202025-09-25%20at%202.24.29%20PM.png "Why traditional roles fail in a dynamic world") ![An architectural pattern for modern authorization](https://solutions.cerbos.dev/hs-fs/hubfs/Screenshot%202025-09-25%20at%202.26.36%20PM.png?width=730&height=947&name=Screenshot%202025-09-25%20at%202.26.36%20PM.png "An architectural pattern for modern authorization") ## An architectural pattern for modern authorization We introduce externalized authorization as the solution, covering Policy Enforcement Points and Policy Decision Points. You will learn deployment patterns including standalone service and sidecar models, plus specific integration strategies for MCP servers. Topics covered: PEP/PDP architecture, deployment patterns, authorization checkpoints, integration workflows. ## Writing rules that your business can understand We cover the paradigm shift from imperative code to declarative policy-as-code. You will master the anatomy of modern policies using principals, actions, resources, and conditions, and learn the careful role of AI in policy management. Topics covered:Declarative vs imperative authorization, policy components, human-readable governance, collaborative security, AI assisted policy tools. ![Writing rules that your business can understand](https://solutions.cerbos.dev/hs-fs/hubfs/Screenshot%202025-09-25%20at%202.28.03%20PM.png?width=730&height=950&name=Screenshot%202025-09-25%20at%202.28.03%20PM.png "Writing rules that your business can understand") ![Extensibility](https://solutions.cerbos.dev/hubfs/Screenshot%202024-12-09%20at%205.10.16%20PM.png "Extensibility") ## Bonus: A comprehensive list of NHI security vendors We’ve compiled a thorough list of NHI security vendors that can help you close this security gap before attackers make use of it. ![Writing rules that your business can understand](https://solutions.cerbos.dev/hs-fs/hubfs/Screenshot%202025-09-25%20at%202.30.41%20PM.png?width=732&height=948&name=Screenshot%202025-09-25%20at%202.30.41%20PM.png "Writing rules that your business can understand") ## How Cerbos delivers on this architecture We demonstrate how purpose-built authorization engines provide the performance and developer experience needed for production MCP deployments. You will see real implementation examples, with stateless architecture benefits, sub-millisecond performance benchmarks, and derived roles in action. Topics covered: Stateless authorization, performance optimization, derived roles, developer workflows, deployment flexibility. ![Emre](https://solutions.cerbos.dev/hubfs/Emre.png "Emre") #### About the author #### Emre Baran, co-founder of Cerbos, ex-Googler, entrepreneur & software executive with 20+ years of experience.
