Model Context Protocol Security

The Model Context Protocol standardizes how AI applications connect to resources, prompts, and tools. Standardization improves interoperability but does not make a connected server trustworthy. A malicious or compromised server may present misleading tool descriptions, return hostile content, request inappropriate access, or change behavior after approval. Clients may also expose capabilities more broadly than users expect.

Important risks include token theft, confused-deputy flows, insecure local server execution, server-side request forgery, command or path injection, cross-server tool confusion, excessive scopes, and approval fatigue. Tool names and model-generated explanations are not substitutes for enforceable policy.

A reference design maintains an allowlisted server registry with owner, origin, transport, version, and review state. The client connects through an identity and policy layer that binds tokens to the intended server and validates redirect behavior. A tool broker maps stable internal identifiers to approved schemas, constrains arguments and destinations, and separates read from write authority. Sandboxing limits local servers; egress rules restrict network reach; and consent screens identify the concrete action and resource.

Subject to agreement, Alexa Cybersecurity can inventory MCP clients and servers, review authentication and authorization, analyze tool schemas and implementation paths, assess local execution and network exposure, and design misuse tests. Outputs may include trust maps, findings, hardened configuration guidance, allowlisting criteria, approval patterns, and monitoring requirements. Coverage is limited to the versions, servers, tools, and environments made available.

Controls may sit in a managed desktop environment, developer workstation, enterprise AI host, remote MCP gateway, or isolated test lab. The design follows an assessment of transport, client behavior, identity provider, server ownership, sensitivity, and tool impact. New servers should start with minimal read-only access and graduate only after review.

MCP can support developer tools, enterprise knowledge access, data analysis, support workflows, and agent automation in technology, finance, healthcare, government, and research environments. Related technologies include OAuth, workload identity, endpoint management, application sandboxing, API gateways, secrets management, EDR, and SIEM. This offering does not imply endorsement of a server, complete protocol conformance, guaranteed containment, or a partnership with protocol maintainers.
